Filteration System
Used to produce drinking or process water, filtration water treatment processes ground, surface or wastewater using many technologies. These include fine mesh screening, media filtration and membrane filtration. Each method effectively separates solids from water.
The filteration process in water treatment have a clear objective: to provide the correct quality of water for the specific industrial application.
Filtration is an important stage when treating water. Firstly, multiple methods of pre-treatment are common. This could include flocculation, coagulation and sedimentation.
Following pre-treatment, various forms of water filtration can be used. For fine screening, drumfilters and discfilters are common. They remove suspended solids from the water and polish effluent from wastewater treatment plants.
Should media filtration be chosen, pressure gravitational filters can be used. These work by the media forming a barrier to the passage of suspended solids, absorbing some compounds contained in the liquids.
Finally, membrane technologies can be used. These include ultrafiltration, microfiltration, nanofiltration, and reverse osmosis. They will retain different sizes of particles and ions, whilst allowing pure water to flow through.
