In order to eliminate any object or particle that can block or disrupt any type of treatments, more specifically the raising of raw water, pretreatment of water in urban areas is the most recommended filtration solution for removing dirt and waste from dirty or worn water.
To achieve optimal sieving, several types of screens are proposed: Multi-squeegee scraper and screen with grid spaces ranging respectively from 1 to 20mm, from 6 to 30mm for each one and perforated hole spaces from 1 to 8mm for the bands’ scraper. Available in two versions with the only difference of being either lateral or central inlet and can also be equipped with rotary sieve.
The type of screening can vary depending on the quality of the water, and at its expense, various operations are possible.
Sand classifiers and heavy body separators are also supplied by Akis.
Once screening refusals are collected, they can be washed or compacted to assure limited costs and nuisances and be valued. We provide compactors with screw or hydraulic piston, compactors and sand washers.
