why treat the wastewater of your restaurant?

Whether in the kitchen, dining room or bathroom, the water you use is loaded with various pollutants. 

  • cooking water  is often discharged untreated and at a high temperature. They will make oils and greases water-soluble, increasing the risk of them not being properly processed.
  • dishwater, dishes are often washed by machines using high-temperature water, which will produce bacteria that will destabilize the receiving environment.
  • cooking fats and oils  have a devastating effect on the environment.
  • ornagic solids : As these elements decompose in water, they ferment, producing among other things hydrogen sulfide (H2S) and methane.
  • cleaning water : Many detergents and surfactant-based products are used.
  • black water can contain pathogens, bacteria and parasites that can cause diseases and infections.

  • static degreaser : A static degreaser physically separates grease and oil. 
  • aerated degreaser : An aerated degreaser, air is blown at the bottom of the tank to improve its efficiency. (recommended for separating the most stubborn greases/oils).

all our degreasers can be fitted with sensors and an alarm system.

desilter and buffer tank

  • desilter : The desilting process separates solid and floating matter from the wastewater. It can also be used to protect the pumping solutions in the next module. Desilting can be carried out either in a separate module or directly in the degreaser, depending on the type of restaurant.
  • buffer tank : The buffer tank will homogenize the quality and temperature of the water coming from your restaurant, while controlling the flow of water to be treated by the downstream solution. Particularly well-suited to restaurants with high hydraulic variations. The installation of a buffer tank is optional and used only for projects that require it.

  1. oxyfix technology : The oxyfix® technology is the most commonly used solution for the treatment of restaurant water. For small and medium-sized kitchens. There are three steps : primary settling /biological reaction /clarification. 
  2. SBR technology : Aeration and clarification take place alternately in a single tank. The water is then discharged to the receiving environment. for community or intensive kitchens.
