Synoptic of a wastewater treatment plant
For each treatment process of a wastewater treatment plant, there is a standard turnkey process, called BOX. As a matter of fact, like a lego, these boxes fit into each other to form a custom-made processing unit dedicated to each project.
The number of different assemblies is almost unlimited! Choose your boxes and assemble your custom water treatment unit!
To mechanically remove large waste that cannot be eliminated by biological or physico-chemical treatment
2 Lifting station
In-line pumping lifts water while avoiding odors and protecting concrete
3 Grit removal
Sand removal allows the sand to be trapped at the head of the plant, thus protecting the downstream equipment. This sand can be revalued later
4 Oil remover
Separates the oil and grease fraction contained in the wastewater (high COD load) for further recovery.
5+6+7 Multi-chamber primary clarifier
All-in-one primary treatment: Sludge separation, denitrification, buffering and sludge storage
5 Buffer tank
Avoid hydraulic and organic overloads, smooth the treatment over time for better efficiency
6 Primary clarifier
To separate the primary sludge from the wastewater, and remove a large part of the TSS, COD and BOD5
7 Mud storage
To store and concentrate primary and biological sludge for final disposal, without generating bad odors
MBBR technology provides advanced carbon and nitrogen treatment, as well as phosphorus bioassimilation
To separate suspended solids and concentrate the sludge, while eliminating the floating sludge fraction
11 Drum filtration
Ideal for achieving high TSS removal when flow rates are high and space is limited
The purified water passes through a UV reactor that eliminates pathogens before it is released into the natural environment.
To avoid unpleasant odors, the stale air extracted from the different stages of the process is filtered on an activated carbon deodorizer.
14 Coagulation Floculation
Coagulation and flocculation are technologies used to agglomerate particles in order to better separate them
