Filter Sand
Filter Sand is naturally occurring, graded and washed silicon dioxide. An inert media, it is hard and durable and has a long service life.
Both silica sand and gravel are carefully selected grade of hard, uniformly graded silica material. They are free from minerals which may precipitate to the systems.
Silica sand is naturally rounded particles of silica or milled angularly shaped particles if silica quartz which usually found in many water filtration system.
Gravel is often being placed at the bottom most layer for backwash enhancement and also avoid damage to the underdrain system.

Graded River Silica Sand
Silica sand is hard grained quartz which able to with sand extreme temperature and high pressure condition. It is an economically feasible filter media for water purification.
Size : 0.6mm - 1.2mm
- Cost effective filter media
- Suitable for most filtration system
- Suitable for multi-media or single media application.
Graded Gravel
Gravel has the ability to hold back precipitates containing impurities, which make it an extremely effective filter media. Its has high uniformity in term of angularity, hardness and size to ensure proper filtering process.
Size : 3mm - 6mm
- Cost effective filter media
- Suitable for most filtration system
- Suitable for multi-media or single media application.
