What is the capacity of the facility?: 2,530 m3/h peak flow Describe the biological treatment technology used.: "The wastewater is pumped via a sewage pumping station through the sewage system to the treatment plant. A sand trap then sucks the sand from the bottom and removes bulky waste using grids. The water then flows to a pre-settling tank. In this concrete tank the remaining heavier particles sink to the bottom: sludge. The sludge is swept from the bottom here and sucked away. The most important part of the purification then takes place in the aeration tank. In this tank are billions of bacteria that eat all the leftover waste. They need sufficient oxygen for this. That is why a lot of air is blown into this tank, causing the water to swirl and foam. The next container is the secondary settling tank. The saturated bacteria sink to the bottom here. There they are swept together with a slowly rotating reamer. Because the bacteria can be reused, they are pumped back to the aeration tank with a large screw. What remains is clean water. We pump this back to a river or canal. But beware: this is not drinking water! There are still substances in the water that only disappear after a longer period of time. In addition to the clean water, there is also sludge left over. This sludge is pumped to the 'sludge thickener' with a large pump. Here the heavier particles from the sludge stick together, leaving a kind of thick mud. In the end, enough water has been extracted from the sludge and it is temporarily stored in a silo. When there is enough thickened sludge in the silo, it is dumped into a truck and transported to SNB's 'sludge incineration plant' on the Moerdijk industrial estate, where it is incinerated. We have sludge digesters at the Bath, Nieuwveer, Dongemond and Waalwijk treatment plants. At these four purifications we fermented all the sludge from all purifications. All digesters supply biogas, ie energy." https://www.brabantsedelta.nl/rioolwaterzuivering How are biosolids (sludge) managed?: Storage in a silo What technology is used for disinfection prior to dicharge of treated water?: Ozone Who is the owner/operator fo the facility?: Waterschap Brabants Delta How is the facility governed?: By the regional government What is the website of the WWTP?: [Web Link]

Please post at least 2 original photographs of the site. We would much rather see photos of the plant itself as opposed to the front office, but we also understand that security and site layout may limit your opportunities.
