1. Coarse Sand (2.4mm) is the most ideal use in domestic & industrial water filtration due to high density and the high level of hardness and toughness. It is efficient for removing particles, sediments, mud and suspended solids in the water.

2. Fine Silica Sand (1.2mm) removes dirts and prevent diseases such as Typhoid, Chlolera, Bihdryia & Amoeba.

3. Fine Sand (0.45mm), further trapping of very fine sediment at the surface of fine silicon sand.

4. Zeolite Sand has an unusual crystalline structure and with greater absorbing power, meanwhile also removes suspended solids, soluble heavy metals & soluble ammonium.

5. Anthracite absorption and high precision, can remove particles, colloidal impurities, suspended solids, or removing iron and manganese. While trapping the sediments, being the primary function of the carbon, it leaves some chlorine in the water.
