Sludge coming from biological processes, physical and chemical processes, etc., both from WWTPs and from industrial WWTPs, is treated by means of THICKENING and DEWATERING systems, by mechanical means.
MANAGEMENT COSTS ARE DRASTICALLY REDUCED thanks to sludge volume decrease.

SIL-PRO: dewatered sludge storage systems
Our dewatered sludge storage systems, SIL-PRO, have an advanced and automated manufacturing system which adds quality and competitiveness to our products, paying attention even to the slightest detail during all manufacture processes. All of them are equipped with:
- Motorized or pneumatic slide gate.
- Sludge collection system equipped with automatic valves (collector cleaning by means of water and air).
- Control panel (silo's opening and closing, and cleaning automation).
- Two stage sludge pump for transferring sludge up high elevations, equipped with heat sensor.
- Access to slide gate via stairs and footbridges.
