“Turning (waste)water into PROFIT”

Every photo tells a personal story that clarifies what “PROFIT” means for Nijhuis customers, Nijhuis team members, business partners and our environment, as a response towards a CIRCULAR economy.

​June | The value of digestate/manure - Nijhuis GENIUS

By: the Nijhuis team and our partners

The award-winning Nijhuis GENIUS solution turns manure/digestate into biogas, green minerals and clean water. The first large-scale “Green Mineral Mining Center” will be built at Groot Zevert Vergisting B.V. Beltrum, the Netherlands. GENIUS is consisting of several modular building block solutions to treat digestate/manure.

Several farmers and manure processing facilities in Western Europe and North America are challenged to manage their manure or digestate. Digestate is the solid/liquid fraction after digesting manure into biogas. Manure consists for more than 90% out of water and low concentrations of minerals, resulting in high transportation costs and impact on the environment by not valorizing the manure. However, pig, cow and chicken manure can be turned into biogas and electricity and green minerals such as clean water and fertilizers.

Total modular solution for manure
Nijhuis GENIUS (in Dutch "GENIAAL")
is a total modular solution for manure and turns raw manure or digestate (the solid/liquid fraction after digesting manure into biogas) into separated phosphate, nitrogen and potassium fertilizer and clean water. The principle of GENIUS is based on producing valuable green minerals from raw manure and digestate and will help for example to contribute by solving the manure- and phosphate surplus in Western Europe based on an innovative, cost saving and sustainable way.

Modular building block solutions
GENIUS is consisting of several modular building block solutions. After the digesters and biogas production, the first step of GENIUS is the separation of manure or digestate into a solid and liquid fraction. The second step is treating the liquid fraction with flotation technology where a large part of the total suspended solids will be removed from the liquid fraction. The third step is treating the liquid fraction with an ammonia stripper and recovery system (AECO-NAR), producing ammonium based nitrogen fertilizer. The fourth step is treating the liquid fraction with membrane filtration followed by evaporation into organic potassium fertilizer and clean water. However, depending on the local situation not all solutions have to be included. At Nijhuis we will closely develop with the client to best possible business case to generate sustainable profit with the lowest OPEX and/or lowest CAPEX.

Green Mineral Mining to achieve regional balanced fertilization
GENIUS is a real “Green Mineral Mining Center” and can produce for example 10-20% in volume of phosphate rich solid fraction with 3-6 % of phosphate, 5-10% in volume of liquid nitrogen fertilizer with 7-8% of ammonium sulphate, 5-10% in volume of organic potassium liquid fertilizer with 7-10 % of potassium and 60-80% of clean water. Clean water can be used as cattle feed water or discharged to surface water. The produced green minerals ensure regional balanced fertilization by dosing sufficient individual nitrogen, phosphate or potassium fertilizers for pasture land or arable crops. This will reduce the rinse of fertilizers into ground and surface water and reduces the use of the chemical fertilizers.

We are proud to build the first Green Mineral Mining Center at Groot Zevert Vergisting together with our partners, turning manure into sustainable profit as green fertilizers and clean water!

Last February, the Dutch television program “Het Groene Oosten” interviewed Arjan Prinsen from Groot Zevert Vergisting and Wilbert Menkveld from Nijhuis Industries about the modular GENIUS solution.

May | Rehabilitated seals return to nature

By: the Nijhuis team

In September 2016, the Nijhuis team visited the Seal Rescue and Rehabilitation Center (SRRC) Pieterburen and released three rehabilitated seals. Five years ago, the Nijhuis water reuse installation was installed at the center. Previously, fresh water was needed to prevent the pollution in the pools because the existing treatment didn’t work sufficiently.

Water reuse installation

As a solution to prevent quickly polluted pools, Nijhuis provided a water reuse installation which ensures huge water savings and clean effluent which meets the customer’s sustainable requirements. The water in the pools has a constantly clear quality which is a huge advantage for the seals and for the team members of the center that visually monitor the condition of the seals. This type of installation is another successful example that Nijhuis supplies smart customized installations in combination with their application knowledge which meets the requirements of the environment and customers.

Nijhuis team reference visit

Early in the morning, the Nijhuis team left by bus to be on time at “Lauwersoog” in the North of the Netherlands. A ship brought the team to the “Engelsmanplaat” for a short walk before visiting the seal center. On board were three young seals which were rehabilitated by the center and were looking forward to enjoy their freedom.

The Nijhuis Staff Association supports the good work of the seal center and therefore they have adopted the three seals. The adopted seals “Hilkia”, “Spetter” and “Lucky “were released back into the Dutch Wadden Sea.

At the seal center, the dedicated staff of the Pieterburen center explained how the Nijhuis installation works and how the seals are rehabilitated. The Nijhuis installation is continuously in operation in order to ensure a good water quality and is consisting of two filters (NDF), Flocculator-DAF (PFR and IPF), effluent polishing (CarboPure) and a disinfection step.

We thank the seal center for their hospitality during this beautiful day and very special moment, turning (waste)water into sustainable profit!

April | Fast track delivery of Nijhuis smart and MODULAR (waste)water treatment solutions

By: the Nijhuis team

Five Nijhuis experts shared their vision about the modular Nijhuis BoxFrame solutions and their impact on fast track delivery and turning (waste)water into sustainable profit.

“Modular and temporary solutions address the requirements of a growing number of customers to extend production infrastructure lifetime, improve sustainability and reduce total cost of ownership”, said Emiel Koster, Area Sales Director at Nijhuis Industries and actively involved in marketing and sales.”

“We design, build and realize containerized, prefabricated skid or/and BoxFrame plants ensuring we have the flexibility to realize a modular plant with the lowest possible total cost of ownership. Our BoxFrame solution is a state-of-the-art modular set-up reducing footprint and simplify civil construction in comparison to conventional plant design and delivery.”

Prefabrication of Nijhuis BoxFrames
According to Barry Domhof, production manager at Nijhuis Industries: “Each modular BoxFrame is manufactured, pre-assembled and equipped with our decentralized electrical control system (i-CONTROL) at our state-of-the-art facilities and thoroughly tested at our sophisticated Nijhuis workshop in the Netherlands.”

Standardization of modules - plug and play
“Due to the standardization and modular nature of the Nijhuis BoxFrames the lead time for the engineering of the project is significantly reduced”, said Eric Thuis, Team Leader Lead Mechanical Engineering at Nijhuis Industries. “Sometimes it feels like we are playing with Lego blocks for adults.”

According to Max Gruson, Service Manager at Nijhuis Industries: “Operators are also actively engaged during the engineering and factory acceptance test acquainting themselves with the technology, which is shortening the hand-over time on site and improving the reliability of the operation.”

Cities of the Future

“Smart and flexible solutions secure trouble-free treatment of wastewater and potable water supply for ‘cities of the future’. By using our innovative modular design philospy cities will contribute to the Sustainable Development Goals, such as SDG 6 (clean water and sanitation), SDG 11 (sustainable cities and communities) at lower costs compared to regular designed solutions!”, ended Wilbert Menkveld, Research & Development at Nijhuis Industries.

We would like to thank Emiel, Barry, Eric, Max and Wilbert for sharing their vision on fast track delivery of smart and MODULAR (waste)water treatment solutions, turning (waste)water into sustainable profit.

MARCH | CLEAN WATER and SANITATION for all

Made by: Toon van den Heuvel, Nijhuis process engineer

Behind the photo
“I made this photo after a field trip to Acherensua where we came to look at works on a water tower that was built there with Dutch development aid. I made it because the people were so happy and grateful seeing us. The particular picture was made at a stand-pipe that is supplied by the new water tower.”

Lessons learned
“We all can learn a thing from the hospitality and gratefulness these people had. The people are genuinely happy receiving water and sanitation facilities even though they have to share one stand pipe with 20 families. In the Netherlands, we consider fresh water from our tap to be normal and don’t ever think about it. I’m privileged to have been born in the Netherlands and could be complaining less and be satisfied more with our standard of living.”

Photo location - Acherensua in Ghana
“Acherensua is a town close to the capital town of the Brong-Ahafo region Sunyani. Brong-Ahafo was created in 1958 from Bono state and named after the dominant and native inhabitants, from the Akan tribe, Brong and Ahafo. The people of Acherensua are mostly farmers working in the cocoa production.”

Brong Ahafo is renowned for its large cocoa production and agriculture agribusiness industries. Brong-Ahafo contains many Akan cultural and wildlife attractions, but it is less known to tourists than the Ashanti or Central region. Major attractions of Brong-Ahafo include Kintampo, with its beautiful waterfalls (Kintampo waterfalls) and nature reserves, and Fiema, home of the Boabeng monkey sanctuary, a short distance outside Sunyani, and national parks, Bui National Park and Digya National Park.

The project
“After completion of the new water tower and 10 stand-pipes the acces to potable water improved. Also the time they had to walk to get water for basic use reduced significantly for a lot of families. The water tower project is part of the aim to improve way of life of about 5000 people in the peri urban area of Acherensua, communities that until now were deprived of access to safe drinking water. Extension of the distribution system coupled with public standpipe construction will improve the access to drinking water against the regular water tariff. This, together with the water and hygiene training will improve health for 5000 people."

We thank Toon for his personal photo and story about improving sanitation and acces to clean water, turning water into sustainable profit for the people in Acherensua, Ghana.

February | MELAMINE REMOVAL from mineral fertilizer wastewater

Made by: Doru Popa, Nijhuis supervisor and health & safety representative on site during the Azomures project

“The story of Azomures WWTP dates back to 2012 when Swiss group Ameropa bought the largest fertilizer plant in Romania-Azomures and engaged in an environmental revamping masterplan. In June 2014 Nijhuis came with the BIOCTOR-MELAMINE solution to treat melamine and other nitrogen containing components and won the contract to deliver this large turnkey wastewater treatment plant for Azomures. We had roughly one and a half years to have a running treatment plant in December 2015. As it was a big project with lots of local subcontractors, Nijhuis hired a local site supervisor to breach the language barrier and also have a local Health and Safety representative on site. This is where I came in!”.

My first contact with Azomures and Nijhuis
“My first contact with this project was in September 2014 when I met the Nijhuis Projects & Engineering Manager and Project Manager for Azomures in a small Italian restaurant near the city centre of Targu Mures.

I enjoyed this first meeting, I really liked the job and after dozens of e-mails, a trip to Doetinchem to meet the project team and other couple of meetings, I was on board in June 2015. By then the works already started and Henk Oosterveld was the permanent Nijhuis staff on site. I must say that it was fortunate that Henk was on site as he is a real character, a good friend and made my transition to this new job easy and smooth”.

The Azomures site
“When I arrived on site the reebars were being mounted for the 2 big clarifiers and the first wall of the biological tank was poured so we needed to put the pedal to the metal because December was fast approaching so from then on, as Henk used to say: “Never a boring day on site”. The pace was unbelievable and soon the empty site started to look like a treatment plant.”

Coordination was the key to success
“Sometimes there were 4-5 companies working at the same time on a relatively small area so coordination was the key to success. You can imagine 2,3 crane trucks, concrete trucks, supply trucks, machinery, tens of workers on an area not much bigger than a football pitch and only one small, muddy access road. I must say Project Manager Rick did an amazing job always supporting us and coordinating everyone. We were also fortunate to have an incredibly helpfull Azomures team which were a huge support during the project.

“With the help of Azomures, our subcontractors CONA, Comterm and Spoting and the Nijhuis project team we managed to meet our deadline and in December the plant was up and running and performing over everyone’s expectations. The test period came soon after, the plant passed with flying colours and it was time to the handover in February 2016 which was a success as well!”.

Official inauguration September 2016
“Azomures decided to leave the operation of the WWTP to Aquaserv, the Mures county water company which took the operation over from Nijhuis and is still running the plant today. The final step of the project was the official inauguration in September 2016 and despite the bad weather it was a huge success. There was a big crowd with government officials, Azomures and Aquaserv staff, lots of media coverage, nice pictures, good food, cutting of the ribbon and champagne. The delegation from Nijhuis consisted of Project Manager Rick Knoops, Henri Besselink, Tomasz Jagielski, Menno M. Holterman, Ronald Ruijtenberg, Emiel Koster, Nijhuis agent/partner Anela Bobocea and myself.

The WWTP has one manager and 2 24/7 operators working there and the results are better than expected. The most important thing is that the client is quite happy with the results of the plant.

As for me, I am still working on the plant as a service engineer and also as a local sales representative and I must say Henks words of wisdom “never a boring day on site” still applies. As I am writing this I’m supervising and improving an emergency return pump. So it’s still a lot of fun!”.

The history of the city of Tirgu Mures
“First of all the city of Targu Mures is my hometown. The name translated to English would be “The Market on Mures river”. It’s a medium size city in the heart of Transylvania, located on the banks of Mures river surrounded by hilly terrain and forests. Its early origins are not clear but archaeological discoveries suggest there were human settlements dating to the stone age so it is as old as it gets. In the medieval period it was a part of the Austro Hungarian empire for hundreds of years and you can still see this as population of Targu Mures is 50% Romanian, 50% Hungarian.

The terrain surrounding Targu Mures is rich in salty water so there are lots of spa resorts and wellness centers. We were almost football champions last year, lost the title in the last game and now our team is bankrupt. After all, we have nice people, good restaurants, interesting nightlife, lots of sporting facilities and state of the art wastewater treatment plant!”

We thank Azomures S.A. for this wonderful project by turning wastewater into sustainable profit towards a circular economy!

Melamine Removal from fertilizer wastewater - BIOCTOR-MELAMINE
The R&D division of Nijhuis Industries developed specially adopted bacteria as seeding sludge to break the melamine in the wastewater, which is quite unique. Worldwide, there are more fertilizer producers who are searching for solutions to treat similar wastewater streams. To break down the melamine, you need specially adopted bacteria as seeding sludge during the start-up of a biological system. Using bacteria from conventional biological treatment plants as seeding sludge will not work. For this particular case, Nijhuis successfully developed these special bacteria.

January | A lone river house with a beautiful view

Made by: Milan Krajnović, Sales Manager Nijhuis Industries in the Balkan region in Europe

Why and when did you make this photo?

“I took the photo of the river house in December 2014 when I visited friends in a small town, Bajina Bašta, in the west of Serbia to celebrate my friend's birthday. We spent three days together exploring the beautiful Drina valley and neighbouring National Park Tara.

Combination of the unique surrounding nature
In Serbia this site is quite well known, however, I enjoyed seeing it with my own eyes. What makes it so special is the combination of the unique, man- made structure and fascinating, intact surrounding nature.

Drina River house

The house on the Drina River is visible at the town entrance and it is one of the town's authentic symbols. From locals I learned that it was a group of boys that came up with the idea to build a resting place in the middle of the river and make sunbathing on the rock more comfortable. The year was 1968 when they put their plan in motion.

They used kayaks to transport some building material. Larger pieces were lowered into the river a few kilometers upstream, carried by the flow, then caught and pulled out on the rock plank by plank. The full standing house was erected on the rock in the middle of the Drina in the following year.

Fishing and resting place
From the time it was built, the house has been used for fishing and as a resting place for any swimmer or a passing kayaker .The Drina is an untamed river and the house was flooded and washed away many times. Sometimes it was successfully brought back, and sometimes the new house had to be built, each time better and stronger. 45 years later, we have the 6th house standing, which was built in 2010.

Drina Regatta
It was this place where the idea of organizing the annual Drina Regatta was thought up - a unique three-day summer event. It features rafting, concerts, parties as well as various contests such as competing in swimming , playing the trumpet and preparing a fish stew.

Hundreds of rafts and boats descent the Drina river starting at Perućac Lake, passing by this beautiful house, and finishing downstream in the town Rogačica. This manifestation gathers ten thousands visitors each year, the river house being its central stop.

I would recommend visiting this magnificent site to any traveller!”
