Pre-treatment, biological clarification, activated-sludge aeration, sludge dewatering, and full EU discharge compliance for large-scale municipal WWTPs
Engineered for municipal wastewater systems — where precision meets sustainability
We provide high-quality preliminary treatment equipment for municipal wastewater, including advanced solutions such as vertical bar screens, arc screens, step screens, drum screens, screw screens, vertical compacting screw screens, rotary drum screens, basket screens, shaftless screw compactors, screening and washing presses, and combined treatment units—engineered for efficiency, durability, and reliable performance.
Our high-quality grit, grease, and sand removal systems efficiently eliminate solids and oils, preventing clogging, wear, and costly maintenance. Ideal for wastewater, industrial, and river intake applications, they ensure smooth and reliable operation.
We supply clarifier scraper bridges built to the dimensions of each tank, including peripheral drive, longitudinal and deoiler/clarifier designs, for efficient sludge collection and transfer.
Our aeration systems enhance secondary treatment through the activated sludge process, promoting efficient microbial growth. We supply Fixed and Floating Surface Aerators, Submersible Aerators, Air Diffusers, Blowers, and Flow Accelerators for reliable performance.
Our high-quality sludge dewatering solutions — including Belt Presses, Filter Presses, and Thickeners — are engineered to reduce disposal costs by efficiently minimizing sludge volume. With advanced technology and a wide range of models, we deliver the perfect solution for every filtration requirement.
Polyelectrolyte preparation and dosing stations for efficient flocculation and sludge conditioning before dewatering. Stainless steel construction, configurable and easy to operate.
ESCA's municipal wastewater treatment portfolio covers every stage of a large-scale WWTP — from coarse screening and grit/grease separation through primary and secondary clarification, activated-sludge aeration, tertiary polishing, sludge dewatering, and polymer dosing. Each equipment line is designed for high-flow continuous operation, corrosion resistance, and compliance with EU and international discharge regulations.
