Product Introduction
Shallow sand filters utilize advanced deep filtration technology, using high-quality quartz sand as the filter media. They are specifically designed to remove suspended solids, particulate impurities, and organic matter from water, and are widely used in industrial circulating water, agricultural irrigation, municipal water supply, and wastewater reuse.
Core Advantages
- High Efficiency Filtration: Wide flow range per unit; can be connected in parallel to meet the needs of systems of different sizes.
- Automatic Backwashing: Equipped with a PLC intelligent control system, enabling timed or differential pressure automatic backwashing without manual intervention.
- Robust Structure: The housing is made of Q235 carbon steel, with a maximum working pressure of 10 bar; corrosion resistant and long service life.
- Flexible Installation: Modular design, small footprint, supports multiple tanks operating in parallel; backwashing does not affect the continuous water supply of the system.

| Notes: 1) When only one filter housing, the filter cannot be backwashed. It can be backwashed only when two filter housings or more in parallel. 2) Clients can choose different quantities of parallel filter housings according to their flow rate requirement. 3) Working temperature: 10-80℃. | ||||||||
