Significantly reduce sand runoff! Installation possible according to the dirt of various filtration materials and the site of the water purification plant.
The "Chiffon-type Filtration Sand Washing Machine" can clean to a turbidity level of 30 degrees or below (JWWA A103 standard), comparable to new sand, as it removes even adhering substances. It is possible to maintain particle size without breaking it down, and to adjust the effective diameter and uniformity coefficient. Excess sludge and manganese layers are stripped away, leaving only the ideal manganese layer. As a measure against Cryptosporidium, it contributes to the guideline set by the Ministry of Health, Labour and Welfare to "maintain the turbidity of filtered water below 0.1 degrees." 【Features】 ■ Avoidance and reduction of sludge detachment phenomena is possible. ■ By returning the specific gravity to its original heavy state, it significantly reduces sand outflow. ■ By cleaning to a selection standard value comparable to new sand through chiffon washing, the reuse of outflow sand becomes feasible. ■ The reduction and reuse of outflow sand can significantly decrease waste. *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Principle of Filter Media Cleaning】 ■ Gravity acting on particles and screw lift create a vortex flow ■ Filter sand forms a complex vortex on the surface of the screw, resulting in the rubbing and washing of the filter sand particles against each other ■ Particles moving outward due to centrifugal force form a vortex *For more details, please refer to the PDF document or feel free to contact us.*
