Next-generation sludge treatment

Our solution

Kemira Superfloc® SD-7083 is a newly developed cationic polymer for wastewater flocculation and sludge treatment applications, mainly sludge thickening and dewatering of digested and secondary sludge. The high-performing structured emulsion polymer helps increase sludge dryness and decrease sludge volumes. This leads to cost savings and minimizes environmental impact. In combination with iron-based coagulants, this technology has led to significant process performance improvements and process efficiency gains, allowing for more efficient chemical dosing in treatment processes.

Benefit for the customer

  • Higher sludge dry solids.
  • Clean centrate.
  • Cost savings through higher product efficiency.

Competitive advantage

The Kemira Superfloc® 7000 series is a next-generation cationic emulsion flocculant for wastewater treatment. Superfloc® SD-7083 is a medium-high structured polymer, delivering high performance and significant process efficiency gains in sludge treatment.
