What Is a Quartz Sand Coarse Filter?

Quartz sand coarse filters are primarily used to remove suspended solids from water. The outer shell is made of high-quality carbon steel, lined with natural rubber or other anti-corrosion layers. The internal structure includes an advanced water distributor, and the internal media can be quartz sand of varying mesh sizes. The equipment features an air flushing function, which maximizes the removal of dirt from the media and bed, improving effluent quality and extending the operating cycle. It can also be combined with a coagulant injection system to form a more efficient filtration system.
