Walnut shell filter

Walnut shell filter is a specially treated walnut shell with walnut shell as the filtering medium. Due to its large surface area and strong adsorption capacity, the removal rate is high. This filter is a separation equipment developed using the principle of filtration and separation. It uses an oil resistant filter material - special walnut shell as the filtering medium. By utilizing the characteristics of walnut shell, such as large specific surface area, strong adsorption force, and large pollutant interception capacity, it can remove oil and suspended solids from water. When filtering, the water flows from top to bottom, passing through the water distributor, filter material layer, and water collector to complete the filtration. During backwashing, the agitator flips the filter material and the water flows from bottom to top, thoroughly cleaning and regenerating the filter material. Has strong adsorption capacity and large pollutant interception capacity; Anti oil immersion, dual effect removal of oil and suspended solids; Easy to regenerate, backwash without adding medication; Capable of being connected in series or parallel.
