Tertiary clarification & water polishing

Tertiary treatment or ‘polishing’ applications are gaining popularity for being used more in improving the final effluent’s quality after biological treatment for either discharge or recycling. There is also a growing need for phosphorous precipitation and additional ‘hard’ COD removal. The KWI Klaricell™ and Flotofilter clarifiers remove the fine suspended solids utilising combined flocculation, dissolved air flotation clarification and single or double media sand filtration in one unit, ensuring the highest efficiency coupled with simple operation and low economics. For smaller flows, KWI also supplies the KS-Filter™, a continuous back-washing sand filter.
