Modular Multi-Stage DEWATS Modules
Nature-based wastewater purification technology requiring minimal electricity, low maintenance, and chemical-free biological operations.
Primary Settler & Biogas Settlers
Heavy-duty primary sedimentation chambers designed for organic solids digestion and initial BOD reduction.
Anaerobic Baffled Reactors (ABR)
Multi-chamber baffle tanks for high-efficiency anaerobic microbial digestion of dissolved organic pollutants.
Anaerobic Filter Chambers (AF)
Fixed-film bio-filter media reactors promoting robust bio-film growth for stable wastewater purification.
Sub-surface Planted Gravel Filters (PGF)
Horizontal and vertical flow wetland reed beds utilizing root-zone phytoremediation for aerobic polishing.
Polishing Ponds & UV Disinfection
Final aerobic stabilization ponds paired with low-wattage UV disinfection units for pathogen-free discharge water.
Sludge Drying Beds (SDB)
Engineered sand-gravel filter beds for eco-friendly dewatering and stabilization of digested organic sludge.
DEWATS Capacity & Sizing Matrix
Select the optimal DEWATS model according to daily hydraulic flow, organic load, and land availability.
| Capacity Range (KLD) | System Configuration | Area Requirement | Energy Consumption | Recommended Application |
|---|---|---|---|---|
| 5 to 15 KLD | Settler + ABR + Planted Gravel Filter | 15 - 35 Sq. Meters | Zero / Gravity Flow | Small Housing Complexes & Resorts |
| 20 to 50 KLD | Biogas Settler + ABR + AF + Reed Bed | 40 - 90 Sq. Meters | < 1 kWh / Day (Pumping only) | Schools, Colleges & Commercial Hubs |
| 60 to 150 KLD | Multi-Chamber ABR + Dual PGF + Polishing Pond | 100 - 250 Sq. Meters | Minimal (Optional Lift Pump) | Gated Townships & Industrial Canteens |
| 200 to 500+ KLD | Modular Parallel DEWATS Trains + UV Skid | 300+ Sq. Meters | Ultra Low Operational Cost | Municipal Colonies & Large Factories |
