Why Use FRP Quartz Sand Filter?

1. Lightweight and corrosion-resistant

- Compared with carbon steel or stainless steel, fiberglass reinforced plastic (FRP) material is lighter and easier to install and maintain.

- It is corrosion-resistant. It is not easy to rust, especially suitable for high humidity, salt spray or weak acid and alkali environments (such as seawater desalination, swimming pool water treatment).

2. The main effect of quartz sand is to effectively remove suspended solids, sediment, colloid, part of the organic matter, and improve the clarity of water.

- Can be used as drinking water, industrial water, reverse osmosis (RO) system of pre-treatment

- Applicable to industrial circulating water, boiler make-up water, swimming pool water treatment, agricultural irrigation, etc.

3. Lower cost

- FRP material is cheaper than stainless steel and carbon steel.

- No anti-corrosion coating, low maintenance costs, suitable for long-term operation.

- Through the backwashing function, the filter media can be cleaned regularly to prolong the service life.

4. Wide range of application, can be used for different water quality treatment

- Household, swimming pool, industrial water treatment: remove particles impurities, improve water quality.

- Agricultural irrigation: prevent clogging of pipes and sprinkler heads, improve the efficiency of the irrigation system.

- Sewage reuse: used for primary filtration, reduce suspended solids in water.

5. Customizable for different flow requirements

- Fiberglass reinforced plastic (FRP) tanks are available in different sizes and flow rates, suitable for small commercial water purification to large industrial treatment systems.

- It can be matched with different filter media (such as manganese sand, activated carbon) to achieve finer water quality optimization.
