3. Industry-Specific Sewage Treatment Solutions: Precision Systems for Compliance & ROI
3.1 Best Sewage Treatment Solution for Residential Complexes
For high-density residential sewage water treatment, eliminating odours and slashing maintenance costs by 70%. These compact decentralised systems are ideal for urban housing societies, processing 5–50 KLD of wastewater while ensuring 95% BOD removal—critical for greywater reuse in landscaping or toilet flushing. With CPCB guidelines mandating stricter residential STP plant standards, ATUs offer a future-proof, odour-free wastewater treatment alternative that aligns with Smart City Mission’s goals for sustainable urban living.
3.2 Best Industrial Sewage Treatment Solution for Heavy Metal Removal
Industries like electroplating, textiles, and pharmaceuticals face stringent PCB norms for heavy metal wastewater treatment. Our hybrid ETP-STP system combines electrocoagulation (removing 99% lead/arsenic) with Reverse Osmosis (RO) membranes to achieve zero liquid discharge (ZLD) compliance. For example, a Chennai-based auto parts plant reduced effluent toxins to <0.01 ppm and cut ₹2.8 crore/year in fines by integrating this industrial wastewater treatment plant. The system also enables effluent recycling, turning treated water into coolant reuse—a cost-saving, eco-friendly wastewater solution for factories.
3.3 Best Municipal Sewage Treatment Solution for Smart Cities
AI-powered sequential batch reactor (SBR) plants are revolutionising municipal sewage wastewater treatment in cities like Pune and Hyderabad. Equipped with IoT sensors, these smart city wastewater treatment systems monitor COD, TSS, and ammonia levels in real-time, automating aeration to reduce energy use by 50%. A 10 MLD plant in Jaipur achieved 100% compliance with Swachh Bharat Mission 2.0 standards using this tech, while biogas recovery from sludge offset 30% of its operational costs—proving that sustainable municipal STP plants can balance ecology and budgets.
4. The HECS Advantage: India’s Leading Sewage Treatment Plant Provider
