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 the 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 are 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. ■ By reducing and reusing outflow sand, it is possible to 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, causing the sand particles to rub against each other ■ Particles moving outward due to centrifugal force create a vortex flow *For more details, please refer to the PDF materials or feel free to contact us.
