Audited Supplier Media sand filter for chilled water as a by-pass filtering equipment of closed industrial circulating water is used to filter the circulating chilled water and its control modes consist of manual backwash and automatic backwash. The system is generally backwashed once every three to seven days in the circulating process, effectively improving the quality of chilled water and ensuring excellent and stable water quality after intervention to long-term running. The device has small water consumption and is widely used in the cleaning of all types of industrial and commercial chilled water circulation system as well as refrigerant water and heat medium water systems of central air conditioning, improving the stability of equipment operation. Users may weld and conned in parallel the by-pass filters in main return pipes depending on the conditions of circulation system and the pipe diameter should be determined based on the retaining water yield of parallel circulating water. The sewage water is then discharged into the sewerage network.
Media sand filter advantages:
State of the art fabrication provides added strength under pressure and long system life
Head construction for durability and safety
Stainless steel wedgewire underdrain
Ensures structural integrity in the harshest conditions
Hydraulically balanced to increase effectiveness of backwash while reducing flush frequency and waste of water
High strength stainless steel wedgewire will withstand a collapse pressure in excess of 600 psi
Standard carbon steel products use 6-12mm thick material
Backwash automatically initiated by elapsed time or pressure differential
Easy-entry lid closure with weld tabs for operator safety
Available in welded carbon steel or stainless steel
Epoxy coating on interior surfaces
Made in China

Media Sand Filter applications :
Multi media sand filter: Removal of turbidity and suspended solids from lightly contaminated water sources such as deep wells and municipality water supplies. Used frequently upstream of reverse osmosis and demineralization systems.
Dual Media or Sand / Anthracite Filters: emoval of turbidity and suspended solids from heavily contaminated water sources such as gray water and domestic sewage tertiary treatment. Also used as a roughening-filters a head of two stage filtration systems.
Activated Carbon Filters: Removal of free chlorine upstream of RO or Softening plants and removing from smell and odor from lightly contaminated water supplies.
