Sewage Treatment System (STP)
Biological Treatment System for Domestic Wastewater Reuse
Sewage Treatment Systems treat domestic wastewater generated from residential, commercial, and institutional facilities, enabling safe discharge or reuse for gardening and flushing.
Detailed Process Flow
-
1Preliminary Treatment Screening and grit removal eliminate rags, plastics, sand, and debris.
-
2Biological Treatment Microorganisms degrade organic matter using technologies such as MBBR, SBR, MBR, or Activated Sludge Process.
-
3Secondary Clarification Biomass is separated from treated water through gravity settling.
-
4Tertiary Treatment Advanced filtration and disinfection improve effluent quality for reuse.
-
5Sludge Handling Sludge thickening, dewatering, and safe disposal or reuse.
Effluent Treatment System (ETP)
Industrial Effluent Management & Compliance System
Effluent Treatment Systems are designed to treat complex industrial wastewater containing oils, chemicals, heavy metals, color, and toxic substances.
Detailed Process Flow
-
1Effluent Collection & Equalization Effluents from various process streams are collected and homogenized to stabilize flow and pollutant concentration.
-
2Chemical Treatment Neutralization, coagulation, and flocculation remove suspended solids, metals, and toxic compounds.
-
3Biological Treatment Aerobic or anaerobic treatment reduces organic load (BOD/COD).
-
4Filtration & Polishing Advanced filtration ensures compliance with discharge or reuse norms.
-
5Treated Water Reuse Recovered water is reused for industrial utilities or further processing.
Zero Liquid Discharge (ZLD)
Complete Wastewater Recovery with Zero Liquid Disposal
ZLD systems ensure maximum water recovery and eliminate liquid waste discharge. They are critical for meeting strict environmental regulations and conserving water in water-scarce regions.
Detailed Process Flow
-
1Pretreatment & Conditioning Chemical conditioning and ultrafiltration to protect downstream membranes from scaling and fouling.
-
2High-Recovery RO (HERO/CCRO) Advanced Reverse Osmosis systems operating at high pressures to recover up to 90-95% of water.
-
3Thermal Evaporation (MEE/MVR) The RO reject (brine) is fed to a Multi-Effect Evaporator or MVR to evaporate water and concentrate solids.
-
4Crystallization & Solids Separation The concentrated slurry is processed in a crystallizer/pusher centrifuge to separate dry salts.
-
5Condensate Reuse Pure condensate from the evaporator is recycled back to the process utility, achieving Zero Liquid Discharge.
Desalination System
Seawater & Brackish Water Desalination Systems
Desalination Systems convert saline water into fresh water using advanced membrane technology, providing a reliable water source for coastal cities and industries.
Detailed Process Flow
-
1Seawater Intake & Screening Controlled intake with screening to protect marine life and equipment.
-
2Pretreatment System Filtration (UF/MMF) and chemical conditioning to protect RO membranes from fouling.
-
3High-Pressure RO System Removes dissolved salts (>99%) and impurities using semi-permeable membranes.
-
4Energy Recovery Device (ERD) Recovers hydraulic energy from high-pressure brine to reduce power consumption by up to 40%.
-
5Post-Treatment & Disinfection pH adjustment, remineralization, and final disinfection for potable use.
Polishing Units
High-Purity Water Conditioning
Polishing units are the final step in the treatment chain, designed to produce ultrapure water for critical industrial applications like boiler feed, pharmaceuticals, and semiconductor manufacturing.
Detailed Process Flow
-
1Pre-Treatment / RO Permeate Feed Water is first treated via UF and RO to remove bulk TDS and organics.
-
2Activated Carbon Polishing Removal of minute traces of organics and chlorine residuals.
-
3Mixed Bed Ion Exchange (MB) Columns filled with Cation and Anion resins polish the water to < 1 microsiemen conductivity.
-
4Electrodeionization (EDI) Chemical-free polishing technology using electricity to continuously regenerate resins, achieving > 16 Mega-ohm resistivity.
-
5UV Sterilization & 0.2µ Filtration Final disinfection and filtration to ensure water is bacteria-free and particle-free at the point of use.
