Waste water stations (WWTP)

The problem

A WWTP had 2 parallel lines designed for treating 11,000 m3 per day each’ and the incoming waste3 flow had reached 14,000 m3 per day.3 Operating the second line would have resulted in additional costs of electricity and maintenance.

The solution

Injection of Sodium Aluminate in the primary settler to reduce the load on the biological reactor, following the well-accepted CEPT technology (Chemically Enhanced Primary Treatment)


The plant continued to operate
using a single line for more than a year.
The quality of
the treated water was not reduced.
