At the suction opening of the pump, it removes algae and large floating matter by means of
a resin fiber suction filter and coarse unwove cloth.
Second Stage Purification Filter
A chemical fiber spool-type filter that removes floating matter larger than 5 microns
including Algae, Rust, and Grains of sand, and protects the membrane.
Third Stage Purification Filter
A Pleat-type membrane filter, same grade as used in generation pure water in the semiconductor
industry, effectively filters and removes microbes and bacteria through its microscopic
openings of 0.05 microns. Furthermore, fibrous activated carbons are employed to absorb
ionized toxic substances, and copper fiber filters and used for sterilication.
All these arrangement combine to produce safe drinking water that meets most strict standards.
