Valveless Filter
The valveless filter is a gravity filter that uses the siphon principle for automatic backwashing, requiring no valves or backwash pumps. With simple operation and management, it is suitable for small and medium-sized water treatment, circulating water side-stream filtration and advanced industrial wastewater treatment.
The valveless filter is a gravity-type filtration device that uses the hydraulic self-control principle to achieve automatic backwashing, and gets its name because the entire system requires no valves. The device integrates filtration and backwashing, making operation and management extremely simple.
Working Principle
Raw water flows into the filter by gravity, passes through the filter media layer, and then flows out of the clear water zone through the siphon riser. As the amount of intercepted pollutants in the filter media layer increases, the head loss gradually increases, and the water level in the siphon auxiliary pipe keeps rising. When it reaches the set height, a siphon is formed, and the stored water in the clear water zone is used to automatically backwash the filter media. After backwashing is completed, the siphon is broken and filtration resumes.
