For swimming pools, aquaculture, industrial water treatment, and landscape water feature purification. Utilizing the interception and adsorption capabilities of a multi-layer bed of precision-graded quartz sand, it effectively removes suspended particles as small as 20-40 microns, delivering crystal-clear, high-quality water you can trust. It is the dependable core component for large-scale water treatment systems.

Key Benefits

Superior Filtration Accuracy for Crystal-Clear Water：Uses specially graded, high-purity quartz sand as media to efficiently remove impurities like silt, algae, organic matter, and suspended particles. With a filtration rating down to 20-40 microns, the output water clarity far surpasses standard filtration methods, achieving a truly "crystal-like" result.

High Dirt-Loading Capacity for Stable, Extended Operation：The deep sand bed provides a vast surface area and tremendous capacity for holding contaminants, significantly extending filtration cycles. This reduces the frequency of backwashing, saving water and energy, and making operation more economical and efficient.

Multi-Port Valve for Simple, Intelligent Operation：Equipped with a top-tier top-mounted or side-mounted multi-port valve. It integrates multiple functions into one: Filter, Backwash, Rinse, Re-Circulate, Waste, and Closed.

Wide Range of Applications & Extreme Adaptability：Excels in diverse settings from private villas and commercial water parks to aquaculture ponds, public aquariums, industrial cooling water loops, and landscape lake treatment. Can be configured as a single unit or in multiple parallel setups for various needs.

How It Works

Sand filters operate on the principle of depth filtration. Pressurized water enters the filter at the top through a diffuser, which distributes the flow evenly over the bed of quartz sand. The water then percolates down through the multi-layered sand bed. Tiny impurities in the water are trapped, adsorbed, and physically screened out by the filter media. The purified water is then collected by the bottom lateral assembly and returned to the pool via the outlet pipe, completing the filtration cycle.
