Intelligent Backwash Sand Filter High Efficiency Filtration for Circulating Water Systems

Intelligent Backwash Sand Filter High Efficiency Filtration for Circulating Water Systems

Brief Description

This equipment employs a shallow filtration principle combined with a unique water distribution structure to achieve high-speed filtration. Equipped with patented vortex backwashing technology, it utilizes the system's own pressure to complete the cleaning process, eliminating the need for an additional backwash pump. The backwashing process takes only 15–30 seconds, with a single water consumption of less than 3% of the total processing capacity. Furthermore, other units continue to supply water as usual during backwashing, truly achieving "zero-interruption" continuous operation, making it particularly suitable for industrial scenarios with stringent requirements for water supply continuity.

Product Overview

The automatic shallow filter device consists of multiple standard high speed sand cylinder units equipped with unique water distributors and collectors.With dual direction automatic flushing valves, it ensures efficient and automatic cleaning of sand filters during normal system operation.

Technical Advantages

The automatic shallow filter utilizes high-quality quartz sand filter material as the medium filter element and achieves fully automatic program control through plc combined control of multiple electric valves.It features advantages such as low backwash water consumption, easy equipment installation, and user friendly operation.With high flow capacity and no maintenance required, this equipment is suitable for water quality treatment in industrial, residential, and landscaping circulating water systems.
