Kaolin for water treatment and effluent clarification
Applications / Water Treatment

Mineral solutions for water & effluent treatment

Sree Sai Mineral Industries supplies washed and spray-dried kaolin clay used as a coagulant aid and flocculation carrier in municipal water treatment and industrial effluent treatment systems.

Our kaolin's fine plate-like particles help bind suspended solids into heavier, faster-settling flocs, supporting clarifiers and settling tanks in delivering consistent turbidity removal, backed by an in-house quality laboratory and a Certificate of Analysis with every batch.

FAQ's

Water Treatment Kaolin — Common Questions

Kaolin acts as a weighting and flocculation-aid mineral. Its fine, plate-like particles provide surface area that helps suspended solids and colloidal turbidity clump together into heavier flocs that settle out faster during clarification.

Our mid-range washed grades with controlled particle size (D50 6–9 microns) are typically used in industrial effluent treatment, giving reliable flocculation performance across varying effluent loads.

We supply in 25 kg and 50 kg HDPE bags, 1-tonne jumbo (FIBC) bags, and bulk container loading for larger water treatment plants and effluent treatment facilities.
