Powder metallurgy company Höganäs Brazil has added a wastewater process based on patent-pending electrocoagulation technology to a SKF bearing plant in Brazil. The customised process is designed to reduce oil, grease and suspended solids and colloids in the wastewater from the plant.

SKF aim was to upgrade its existing wastewater treatment facility in order to exceed current environmental regulations.

This project combines Höganäs Cleanit EC technology with additional polishing steps, featuring zero liquid discharge (ZLD) which enables SKF to reuse the treated wastewater. The patented Cleanit EC porous electrodes are made from recycled metal, using green hydel power.
