WATER TREATMENT SYSTEM COMPRISING WATER-SOLUBLE GLASS

摘要

A water treatment system for submersion in a body of water to be treated comprises a water-soluble glass treatment agent and a water-insoluble retaining means for the water-soluble glass treatment agent. The retaining means is adapted, in use, to retain water in contact with the water-soluble glass and may be a hollow container for the water-soluble glass or a moisture penetrable polymer composition which can be used as a matrix containing particulate water-soluble glass. The water treatment system may be immersed in water to act over an extended period of time in preventing or reducing problems caused by corrosion, scaling and/or fouling.
