Technology to control excess sludge generated in biological wastewater treatment

Technology / Service Summary

Technology that greatly reducess the amount of excess sludge in biological treatment using the KIDS system

Purpose

When introducing aerobic biological treatment equipment,it is difficult to treat excess sludge because the infrastructure for treating excess sludge has not been
developrd.
By suppressing the generation of excess sludge,the coat of sludge disposal can be greatly reduced,so it can be introduced at each business site.

Feature

There is no additional cost for chemicals or additional equipment to control excess sludge.

Effect

When this system is introduced,the amount of surplus sludge is reduced to about 1/2~1/5 of the normal amount,although the effect varies depending on the operating conditions and water quality.
