Compact Structure Rapid Backwash Sand Filter Low Energy Consumption Continuous

Product Specification

Compact Structure Rapid Sand Filter Low Energy Consumption Continuous Filtration

Brief Description

Compact structure saves space, stable operation and low energy consumption, making it an ideal choice for modern industrial water treatment. Utilizing the shallow filtration principle, combined with automatic differential pressure or timer control, it achieves continuous and uninterrupted filtration. Widely used in the raw water pretreatment stages of the power, metallurgical, and chemical industries to ensure clean water quality and extend equipment lifespan.

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.
