A special filter material developed to remove humic chromaticity. The presence of an oxidizing agent such as sodium hypochlorite in water acts as a catalyst to generate O-radicals with strong oxidizing power, which cleaves the bonds of chromophores and axochromes in humic substances. The chromaticity is reduced.

* No sludge is generated.
* Easy daily maintenance.
* Easy to handle existing equipment.
* You can reduce the frequency of backwashing.
* Basically, performance can be maintained by replenishing every year.

* Radical lights UC3 and SC3 are used when manganese is contained in the raw water.
Since manganese is oxidized and removed, the chromaticity removal performance may deteriorate.
Therefore, please remove manganese first before using.

What is humic chromaticity?

Well water and river water often have chromaticity due to humic substances, which are difficult to remove even by normal water purification treatment (coagulation sedimentation, filtration, iron removal, manganese removal). Humic substance is a general term for dark brown organic matter in soil, and it is said that ancient plant components are decomposed by microorganisms, and it is widely confirmed in Japan, which is a forest country, all over the country. The size of the colored substance due to humic substances is several nm, and it is an organic substance with a relatively high molecular weight, but it is difficult to remove by physical filtration, and very strong oxidizing power is required for oxidative decomposition.

The chromaticity specified by the tap water quality standard is 5 degrees _or less.
Humic substance chromaticity is found all over Japan, but it is recommended to use [Radical Light UC3] especially when there is concern about raw water with chromaticity of 8 degrees _or more _and water quality fluctuations found in the Kanto, Tohoku, _and Hokkaido regions. I will do it.
Use [Radical Light SC3] if you want to remove some raw light blueness [for example, reduce it by 2 to 3 degrees].
We recommend that you conduct a verification test to select the filter media _and confirm the removal capacity. Please contact us for consultation such as selection.
* Radical light UC3 / SC3 does not remove artificial pigments such as dyed wastewater.
