Optimization model sludge streams – Waternet
On the site of WwTW Amsterdam West, the sewage sludge of twelve WwTW’s managed by Waternet (Water board of Amsterdam and surrounding areas) is being processed. The sludge is digested, dewatered and subsequently burned at AEB. After the shutdown of the digestion facility at WwTW Hilversum the load to the facility in Amsterdam increased. As a result, the hydraulic residence time in the digester decreased, which may lead to a lower biogas yield. By optimizing the logistics of the supply of sludge to the Central Sludge Receiver (CSI) the overall biogas output of the digester could be increased.
Surface water system – Efteling
The Efteling, the most famous Dutch theme park in the South of the Netherlands invests in water-themed attractions, shows and facilities continuously. Water is a very important factor in the park and hence both water quality and quantity needs to be managed carefully. Brightwork engineered the water system and re-mapped the present set-up in order to improve maintenance and operational efforts.
Startup plan WwTW Hilversum – Waternet
The new WwTW Hilversum was completed in autumn 2013. The start-up procedure of WwTW Hilversum has been registered and implemented by Brightwork.
A startup and conversion plan indicating what to do before, during and after the startup of the new WwTW has been designed
Master plan waste water treatment plant Venray – Rixona BV
A master plan how to deal with waste water treatment and water reuse was composed. The plan has led to concrete recommendations for optimization of the waste water treatment plant.
Masterplan RWZI Utrecht – Hoogheemraadschap de Stichtse Rijnlanden
Water authority Hoogheemraadschap de Stichtse Rijnlanden, abbreviated HDSR, manages the sewage treatment of Utrecht with a capacity of 450,000 PE. At this site, situated in the center of the city of Utrecht, domestic wastewater treatment and sludge handling takes place.
Green energy from GFT – Attero
Attero’s compost plant in Venlo has been processing vegetable, fruit and garden (GFT) waste from the households of South Netherlands for over fifteen years. To promote sustainability and boost the energy efficiency, research has been conducted to extract GFT biogas by integrating anaerobic conversion of organic material with existing aerobic composting process.
New sanitation Rijnenburg – Hoogheemraadschap de Stichtse Rijnlanden
The study involved a scan for separate collection and treatment of domestic wastewater at source and translating the result into actual implementation at the new district of Rijnenburg. A blueprint was prepared to provide a new sanitation system in the district.
CADoS – Cellulose Assisted Dewatering of Sludge
The concept of CADoS is based on the efficient separation of cellulose fibers from raw wastewater and their reuse for dewatering excess sludge. This form of resource recycling proves to be advantageous due to a simpler sludge handling on site, minimal chemical consumption, lower energy consumption and lesser sludge transport.
Contract management
Brightwork performs contract management in the broadest sense of the word for various clients. Here are some examples of projects that we have co-designed.
Development of Sand-Cycle for continuous sand filtration
The use of RFID tags for “chipping” cats is well-known. Likewise, the use of similar tags for monitoring purification/treatment technology has not been available till the recent past. Brightwork has made RFID technology suitable for continuous moving bed sand filters therewith initializing an important step towards remote monitoring and remote control.
Applied research into new sludge separation technique initiated
Brightwork is working on a new technique for advanced sludge separation, without using chemicals and with low energy input. After the proof-of-principle further development for various applications is required. This research will be executed in 2018 at the Water Application Centre (WAC) in Leeuwarden.
