According to the regulations, the waste water must be poured into the natural environment at a temperature below 30°C. To achieve it, the use of plate heat exchangers gaskets are the most appropriate instrument for energy savings with the recovery of calories from effluents.
In addition, the fact of controlling the temperature of these effluents is also essential in the optimisation of the different treatment phases.
Finally, it goes through a process of methanization in which biogas is obtained thanks to the recovery of the waste. Moreover, the degradation of waste requires a constant and controlled temperature achieved by the use of heat exchangers.
