Product Description
XLSG High-Efficiency Flowing Sand Filter
The XLSG series of high-efficiency flowing sand filters is an innovative, uniquely designed, high-tech, and environmentally friendly product. This filtration equipment effectively removes suspended solids and colloids from raw water (or wastewater). In water treatment and wastewater purification, removing solid suspended matter and other impurities through sand bed filtration is the most cost-effective solution. This filtration equipment cleverly performs the filtration and sand washing processes simultaneously and separately in different parts, eliminating the need for a clear water tank and a high-power backwashing pump, allowing for continuous and stable filter operation. During the entire filtration process, the filter media (sand) flows downward in a cycle, while the raw water flows upward, allowing the raw water and quartz sand to come into full contact, intercepting suspended substances. It has the advantages of high filtration efficiency, low energy consumption, and simple operation, and can be widely used in various water treatment processes.
Features continuous operation without the need for specialized backwashing equipment.
The unique cleaning device only requires a small amount of cleaning water (filtered water) to achieve complete filter media cleaning.
Flexible and convenient operation, allowing for free adjustment of air delivery volume and pressure.
The special conical sand distributor ensures uniform descent of the sand in the filter bed, preventing filter bed clogging and keeping the filter media clean, thus improving filtration efficiency.
Low operating costs, with power consumption limited to the raw water pump and air compressor.
Simple system structure and configuration, convenient design and installation, enabling unattended operation and minimal maintenance.
Working Principle
1. The water to be treated flows in from the water distributor at the bottom of the equipment, flows upward through the filter bed to be filtered, and then flows out from the filtrate outlet at the top.
2. Filter sand containing treated impurities is lifted from the conical bottom of the equipment by a pump to the sand washer at the top.
3. Sand cleaning begins in the pump; under turbulent mixing, impurities are separated from the sand particles. Dirty sand overflows from the pump outlet and enters the corrugated tube of the sand washer, where it is thoroughly rinsed countercurrently with a small flow of clean water. Impurities are discharged through the sand washing water outlet, while the cleaned sand particles (heavier) return to the sand bed.
4. As a result, the sand bed continuously undergoes slow subsidence movement within the equipment. The pump is powered by compressed air supplied through the control panel.
