ARCK's standard sand filter tank has an octagonal design for the water collector. Its unique precision gap can collect filtered water evenly. The water outlet is designed at the bottom, making the overall structure more compact and occupying less space. With anti-rust treatment, the sand filter tank becomes strong and durable.

• High filtration speed, low pressure loss, high filtration efficiency.
• Especially suitable for filtering suspended impurities in water.
• There are many sizes to choose from. From 16"(400mm) to 60"(1500mm)
• Stainless steel material, corrosion-resistant
• Configure automatic controller, built-in intelligent chip, can run automatically.
• Using quartz sand as filter medium.
• The maintenance port is reserved for easy cleaning and maintenance at any time.

The filter system consists of filter unit, three-way back flushing filter valve, automatic back flushing controller and other major components, and to connect with Y-type filter, air valve, pressure gauge, manifold, support frame and other spare parts , the filter unit is filled with the appropriate filter media.

Filtering:Under the control of the automatic controller, when the whole system are in the filter state, the sewage enter with the high pressure, through a unique water distributor to keep the water distribution filter sand smooth, the flow of laminar flow through the filler layer, Impurities are trapped in the filler layer. Through the bottom of the distribution of multiple water collectors, Filtered can clean water ,evenly collected through the outlet pipe out. The advection filter allows the filter to operate at high flow rates.

Backflushing:As the impurities accumulate in the filter medium, the pressure loss increases, and when the differential pressure increases to a certain setting value or reaches the setting cleaning time, the system automatically switches to the backflush state. The pressurized water enters the filter medium through the water collecting device, flushes it, separates the trapped contaminants and discharges the filtration system through the sewage outlet. The backflush ends after 2 minutes, the back flushing control valve returns to the filter state, then the rinsed filter tank continues to enter the filter working condition. The automatic controller issues an instruction to start the backflushing process of the next filter sand column ,until all the filter cylinders are rinsed again.
