Product description

Working principle of sand filter
• Mechanical sand filter, also known as pressure filter, is an important part of the pre-pure water pretreatment and water purification systerms. Mechanical sand filter packing is mainly used to reduce water turbidity, remove the water suspended particles, organic matter, colloidal particles, microorganisms, residual chlorine and some heavy metal ions.
• The turbidity of raw water require less than 20 degrees, and it will up to 3 degrees when the filtration completed.


Application of sand filter
• Chemical, petroleum industrial, pharmaceutical, light industry, food, mineral processing, water treatment, electroplating, metallurgy, textile, dye industry.
• Preparation of cooling water
• Filtration of gray or surface water
• Pre filtration for RO (membrane) systems
• Drinking water
• Treatment of waste water
