Ecopure Crushed Glass

Waterco's Glass Filter media is manufactured from recycled glass, it is an environmentally friendly and viable alternative to sand. Plis it offers finer filtration than sand. 

High Purity

Whereas other filter media may contain a variety of contaminants, Waterco's Glass filter media is chemically inert for superior purity. In fact, it does not contain any crystalline free silica or heavy metals.


Raw material is taken directly from household recycling schemes and is 100% recycled glass.

This offers environmental savings when compared with alternative natural resources which would otherwise be used.

Chemical Compositions

Silicon dioxide (SIO2)72.2%
Sodium oxide (Na2O)13.3%
Calcium oxide (CaO)10.9%
Magnesium oxide (MgO)1.65%
Aluminium oxide (AL2O3)1.5%

Depth Filtration

Glass filter media operate on the basis of "depth filtration" : dirt is driven through the filter bed and trapped in minute spaces between the particles of filter media allowing the cleansed water to pass through.


It removes more materials and pollutants  than sand, saving on backwashing and resultant water, heating and chemical treatment costs.


It is less susceptible to bio-fouling. The heat-treated surfaced are smooth, requiring less remedial action and less chemical treatment to kill pollutants.

Long Life

It has undergone specialised heat treatment process, which means that its degradation is lower and it therefore has a longer life span.
