Compact Inclined Plate Lamella Clarifier DAF Sludge Separation Municipal Wastewater South America

• Optimized for Municipal DAF Integration

  Specifically designed as the downstream sedimentation stage for dissolved air flotation (DAF) systems in municipal wastewater treatment plants, effectively capturing DAF float sludge and polishing effluent to meet strict discharge standards across South America.

• Space-Saving Compact Footprint

  Requires up to 80% less land area than conventional circular clarifiers, making it ideal for urban municipal treatment plants in South American cities where land is at a premium.

• Uniform Hydraulic Distribution

  Isobaric linear water distribution technology ensures laminar flow conditions, eliminating short-circuiting and dead zones for consistent effluent BOD and TSS compliance with local regulations including Colombian RAS and Peruvian D.S. N° 003 standards.

• Low Maintenance Self-Cleaning Design

  Integrated backwash system and optimized plate spacing prevent biofouling and sludge accumulation, reducing operator intervention and maintenance costs in municipal facilities.

• Reliable Automated Sludge Handling

  Dead-zone-free sludge hopper with mechanical scraper ensures continuous, consistent sludge discharge to thickening or dewatering equipment downstream.

• Corrosion-Resistant for Long Service Life

  Constructed with SS304/SS316L stainless steel plates and high-grade structural steel with epoxy coating, delivering decades of service in municipal sewage environments.

• Secondary Clarification After DAF

  Polishes DAF effluent by capturing residual suspended solids, achieving 95%+ TSS removal and reducing BOD loads before discharge to receiving water bodies.

• DAF Sludge Thickening

  Concentrates DAF float sludge from 1-3% to 4-6% dry solids, significantly reducing sludge volume and downstream dewatering costs.

• Stormwater Overflow Treatment

  Handles peak wet-weather flows in combined sewer systems, providing high-rate clarification during storm events common in tropical South American climates.

• Plant Upgrade and Expansion

  Ideal retrofit solution for upgrading existing municipal WWTPs to meet tighter effluent regulations without expanding the plant footprint.

• Brazil

  Meets CONAMA 430/2011 effluent discharge limits for BOD, TSS, and nutrients in municipal wastewater.

• Colombia

  Complies with RAS 2017 Title E treatment standards and Resolución 0631/2015 discharge parameters.

• Peru

  Designed to meet D.S. N° 003-2010-MINAM maximum permissible limits for municipal effluent.

• Chile

  Compatible with DS 90/2000 emission standards for liquid industrial and municipal waste.
