Washing Tower - Solution from 436 € HT

Physico-chemical absorption techniques consist to divert smelly compounds or COV from a gaseous phase to an aqueous phase by using Exchange columns. The aqueous solutions used in the gas washing towers are most often associated with specifically targeted chemicals (sulphuric acid, bleach, soda...) to obtain a complete cleaning.

Issues
- Odors rejected by re-circulating water

Solution: Process of finishing in the last tower by mass incorporation of reagent.
- Hardware : Adjustable pump
- Product : NORASYSTEM C 503 L0 (Link to product sheet).
- Amount : 0,025%
- Cost = 11,2 €/m³ of water dilution (overflow)

Clarifier (Decanter vessel) - Solution from 11 301 € HT*

* for a pool of 50 m of perimeter

The clarifier allows decantation by flake gravity. A part of the formed mud is then sent for fermentation of the aeration basin. Treated waste water is retrieved by overflow, then via a channel are returned to the middle.

Issues
- Ammoniac, H2S, Mercaptans

Solution: Processing gazeous cloud basins. Establishment of nozzle broadcasting at the edges around the basin.

Traitement of sludge site - Solution from 9 136 € HT

Sludge is retrieved from clarifier and pre-thickened in a static thickener. They are ejected either to be thickened (liquid sludge 60 g/l), or dehydrated (Pasty sludge to 200 g/l). Thickened sludge is recoverable by agricultural spraying.

Issues
- Ammonia, H2S, Mercaptans

Solution : Implementation of nozzle broadcast around the sass to handle the building’s atmosphere and to doors opening vacuum effect..
