Environment Management
Compliance with CPCB and State Pollution Control Board norms is non-negotiable. JS Engineering provides integrated environmental solutions that go beyond compliance — recovering energy, reusing water, and reducing your plant’s ecological footprint.
Pulse Jet Bag Filter Systems
High-efficiency pulse jet bag filters for capturing fine particulate matter from boiler flue gas, dryer exhaust, and process streams. Modular design, online cleaning, and low compressed air consumption. Suitable for temperatures up to 200°C with appropriate fabric selection. Achieves outlet emission below 50 mg/Nm³ — well within CPCB norms.
- Engineering design & sizing
- Fabric selection for temperature & chemistry
- PLC-based pulse controller supply
- Site installation & commissioning
- Fabric bag replacement service
Reverse Air Bag Filters
Reverse air regeneration bag filter systems for large-volume, low-pressure applications such as kiln exit gas, high-temperature processes, and recovery boilers. Lower fabric mechanical stress vs pulse jet — ideal for woven glass fibre and P84 fabrics in high-temperature duty above 220°C.
- High-temperature duty design
- Large-volume flow applications
- Woven glass fibre fabric supply
- Compartment isolation controls
- Performance guarantee protocols
Effluent Treatment Plant (ETP)
Design and build of complete ETP systems for industrial effluents — textile, chemical, food processing, pharmaceutical, and general manufacturing. Physico-chemical treatment, biological treatment (ASP, SBR, MBR), tertiary polishing, and Zero Liquid Discharge (ZLD) systems for consent compliance.
- Inlet characterisation & treatability studies
- Primary, secondary, tertiary treatment
- SBR / MBR / MBBR technology
- ZLD integration
- Sludge dewatering systems
Fresh & Waste Water Treatment
Potable water treatment systems (clarification, filtration, softening, RO, UV disinfection), raw water pre-treatment for boiler feed, cooling tower make-up, and process water. Effluent recycle and reuse systems to reduce fresh water draw and achieve near-ZLD operation.
- DM plant / softener systems
- Reverse osmosis (RO) plants
- Ultrafiltration systems
- Clarifiers and multimedia filters
- Water recycle & reuse engineering
Heat Pump Systems
Industrial heat pumps for simultaneous process cooling and heat recovery — replacing standalone chillers and boilers with a single, energy-efficient system. Electrical heat pumps (COP 3.5–5.0) and hybrid heat pumps (combined gas-electric) for year-round baseload operation.
- Electrical heat pump (EHP) supply & install
- Hybrid heat pump systems
- Process cooling integration
- Hot water recovery for process/utility
- Energy audit & ROI analysis
Closed Loop Cooling Tower
Closed circuit fluid coolers eliminating direct process fluid-to-atmosphere contact. No risk of process contamination, reduced blowdown, and lower water consumption vs open cooling towers. Ideal for sensitive process cooling — hydraulic systems, compressors, quench loops, and food processing.
- Closed loop fluid cooler selection
- Glycol circuit design
- Chemical treatment programme
- Automatic conductivity & pH control
- Heat load & wet-bulb sizing
Adiabatic Cooling Tower
Adiabatic pre-coolers and adiabatic cooling systems that use evaporative pre-cooling of inlet air to air-cooled heat exchangers — dramatically reducing peak-load power consumption without water-wetted surfaces in the heat exchanger core. Ideal for dry climates and water-scarce regions.
- Adiabatic media pad selection
- Spray nozzle system design
- Humidity-controlled operation
- Integration with air-cooled condensers
- Annual water savings calculation
Evaporative Condenser
Direct evaporative condensers for refrigeration and industrial HVAC systems — combining the condenser and cooling tower in a single compact unit. Up to 30% smaller refrigerant charge, lower condensing temperature, and significantly higher system COP vs air-cooled condensers.
- Refrigerant compatibility review
- Fill media selection
- Drift eliminator specification
- Legionella risk management plan
- Winter operation provisions
Heat Condensation & Recovery
Waste heat recovery from boiler flue gas, compressor heat rejection, cooling tower condenser water, and process streams. Economisers, heat exchangers, heat recovery steam generators (HRSG), and condensate recovery systems that turn energy losses into productive plant utilities.
- Flue gas economiser supply & install
- Condensate recovery systems
- Blowdown heat recovery
- Process-to-process heat exchange
- Energy recovery audit & reporting
