haydraulics MPS is able to achive fast and efficent
water clarification & solid recovery in various water
domain.

Upflow Hybrid Anaerobic Baffled Reactor (UHABR)

The Upflow Hybrid Anaerobic Baffled Reactor (UHABR) is a robust, low-maintenance solution engineered to treat high-COD wastewater streams with exceptional efficiency. Designed for minimal sludge generation and superior shock load resilience, UHABR operates with near-zero operational expenditure—making it ideal for industries seeking sustainable, cost-effective wastewater management

Advanced Aeration with Retrievable Diffuser System (RDS)

SPIL’s Retrievable Diffuser System (RDS) is a modular, low-maintenance aeration solution engineered for uninterrupted operation. Configured in multiple removable grids, the system allows for easy extraction from the aeration tank for inspection, repair, or replacement—without requiring tank drainage or aeration shutdown,offering a highly cost-effective alternative to conventional aeration systems.

Auto-Backwash Media Filters and Ultrafiltration System

SPIL’s Auto-Backwash Media Filters & Ultrafiltration (UF) systems are engineered for high-performance tertiary treatment, effectively capturing microparticles including colloidal matter and fines. Fully automated and integrated with PLC/DCS controls, both systems deliver consistently high-quality clarified water—ready for direct reuse within the process stream

Rotary Screen & 3 Wire Dewatering Belt Press

SPIL’s advanced sludge and fiber handling equipment—including Rotary Screens & Dewatering Belt Presses—are engineered for superior reliability and efficiency. The rotary screen also serves as an effective pre-screening unit for wastewater streams, while the belt press ensures consistent sludge dewatering. Designed for low maintenance and maximum uptime, these systems provide clients with a cost-effective and dependable solution for sustainable solids management.

Equaflow clarifier

SPIL Equaflow Clarifier is an innovative solution that combines equalization and pre-clarification in a single, space saving unit. designed to handle high variation in flow and suspended solid, it ensures consistent and clear effluent for down stream biological processes.

Service Portfolio

Water Audits & Source Assessment

Evaluate raw‐water sources (surface, groundwater, rainwater) and map consumption hotspots to uncover savings opportunities.

Process Water Conditioning

Engineer and install treatment trains—sedimentation, multimedia filtration, ultrafiltration, reverse osmosis—to deliver fit-for-purpose process water.

Process Optimization

Implementing retrofit engineered design and equipment to reduce water consumption and excess/reject water generation in the production process ,decreasing specific water use& reject generated per tonne of product.

Effluent Treatment Plants (ETP)

Design, erection & commissioning of primary, secondary, and tertiary treatment stages based on influent profiling, site conditions, and discharge targets.

Zero-Liquid-Discharge (ZLD) Systems

Integrate RO with evaporators, crystallizers, & brine concentrators for complete water reclamation and zero effluent release.

Water Recycling & Reuse

Close water loops—recycle treated effluent into make-up, washing, and cooling circuits to slash freshwater demand. At source treatment of water for efficient reuse of treated water.

Sludge Dewatering & Valorisation

Deploy belt filter presses, centrifuges, or filter presses to reduce sludge volume and enable safe disposal or resource recovery( fibre recovery, boiler feed use etc.).

Digital Monitoring & Remote Diagnostics

Install IoT sensors, SCADA dashboards, and predictive-analytics platforms for real-time water-balance tracking and early fault detection.

Implementation Roadmap

Step by step journey to smarter, sustainable water management.

Site Assessment

Preliminary data collection & analysis, conduct a comprehensive water-balance study, benchmark against industry best practices, & quantify reduction opportunities.

Conceptual & Detailed Design 

Develop tailored treatment trains, equipment selection, equipment layouts,P&ID, and automation schemes.

Equipment manufacture and supply

Manufacturing of tailored designed equipment; end to end vendor selection, procurement and procurement support for bought out equipment and system.

Turnkey Execution  

Manage civil works, mechanical installation, electrical integration, and system commissioning.

Training & Handover

Upskill operations and maintenance teams, deliver SOPs, and provide digital-monitoring handoff.

Continuous Improvement  

Monitor key metrics—specific water use, effluent load, ZLD compliance—then refine operations through periodic audits and optimization cycles.

Design Considerations

Influent characterization: flow variation, COD/BOD ratio, solids content
Local regulations: discharge limits for BOD, TSS, nutrients, heavy metals
Reuse goals: process water recycling, boiler feed, irrigation
Energy balance: biogas recovery from sludge digestion, heat integration
Scalability and modularity: future capacity expansions
