Clauger assisted an industrial in the management of its liquid effluents, emanating from its air decontamination installation
It had a twofold objective:
A test of the filtration has been set up with a band filter prototype, designed by Clauger and entirely made out of plastic.
This trial lead to the manufacturing and installation of a motorized and automated filter, enabling to filter the filtration of the total volume of re-circulating liquids, at a flow of 8 m3/h.
The solution consisted of using a series of 3 tanks measuring 1 cubic meter each, filled with marble that is transformed into gravel.
As the liquid flows through the gravel, the acid will dissolve the marble and neutralize (calcium chloride and calcium acetate will form).
At the end of the cycle, the liquid effluent are at a pH rate located between 5,5 and 6. The liquid effluents may then be rejected in the production plant’s wastewater collection system, instead of being disposed.
With this solution, the estimated savings made by the client are significant; approximately 700€ per operating day.
