Continuous waste water treatment

Polishing is a high-stream filtering process where suspended solids and BOD are removed from wastewater. Polishing removes remaining suspended solids and BOD that may be left after secondary effluent treatment. Polishing usually is the end phase in wastewater treatment process to make water more hygienic and environmentally safe for discharge into receiving waters. HOW DOES WASTEWATER POLISHING WORK During polishing process, wastewater passes through a cascade of fine high-stream sand, charcoal, fabric and/or carbon filters that gradually reduces particle size in the effluents to 10 microns (0,001 μm). Filters cause the waste particles from water to attach to the filter media thus making the water free of such particles. EQUIPMENT NEEDED FOR WASTEWATER POLISHING The goal of wastewater polishing is to create a system which produces water that is ready for release in environment. Technology of wastewater polishing include various filtering and and automatic air-water backwashing solutions. Backwashing (also known as CIP - cleaning in place) is crucial to prevent the filters from clogging. Incorrect backwashing may decrease filters’ life significantly and result in extra maintenance costs. For wastewater polishing, FlotLife delivers following equipment and services: -high-stream sand media filters for micro-filtration (particle size >0,2 μm) -membrane filters for ultra-filtration (particle size >0,1 μm) -membrane filters for nano-filtration (particle size >0,01 μm) -semipermeable membrane filters for reverse osmosis (particle size >0,001 μm) -installation, training and support
