The Two Major Elements in Combating Turbidity. Product Introduction from the Perspective of Turbidity - NIHON SOLID CO., LTD., Water Purification and Environmental Conservation

Silt clay and colloid microparticles of diameter less than 75 – 1 μm mutually repel each other and are said to be diffusion particles that do not precipitate over time. The surface area of these microparticles is large making them susceptible to vortex flows etc. and difficult to precipitate; however they possess the characteristic of being easy to adhere and flocculate. In a natural river, they adhere to gravel and water plants etc., are collected in “stagnation zones” in the vicinity of meandering sections and piers etc., and undergo hindered settling. Drawing on these diverse functions of water, we have broadly differentiated clarification methods into two categories. We will propose the optimum method to match the application.

・Slight alkali flocculation
・Deodorizing, antibacterial
・Gravel contact, filtration

・Immediate reaction by mixing flocculation elements (Reactions that take place a long time after coagulant feeding risk inferior flocculation due to diffusion.)

・Continuous solid coagulant

・High-density flocculation and all-purpose coagulant

・Optimum result from multi-point flocculation

・MLIT NETIS registered

・Precipitation promotion through microparticle agglomeration

・Usage in a MOC system is effective

・P-1NR (Rush)Assembled precipitation/adhesion/contact in the stagnation section

・P-1NR-W (Rush) Ladder-TypeForms a stagnation zone and a deposit section in the flow and promotes co-precipitation and hindered settling

・P-1 (Sheet)Promotes Kármán vortexes and hindered settling

Providing technological development products relating
to water purification and environmental conservation, and supporting the improvement of environmental quality.

Usage near the boiler room/sedimentation basin/desilting basin is effective.
