Facilities & Engineering Capabilities

Facility #1

Treatment, Storage & Disposal Facility (TSDF)

Our Common TSDF is designed strictly according to CPCB and MoEFCC guidelines for hazardous and industrial solid waste management. It incorporates multi-layered engineered double composite liner systems, continuous leachate extraction, and a dedicated chemical stabilization laboratory.

Multi-Barrier Double Geomembrane: HDPE liners (1.5mm / 2.0mm) with non-woven geotextile protection and 90cm compacted clay barrier (permeability < 10⁻⁷ cm/sec).

Stabilization & Solidification (S/S): Chemical neutralization and heavy metal fixation (Cr⁶⁺, Pb, Cd, As) using pozzolanic and polymeric additives prior to cell deposition.

Continuous Leachate Management: Perforated HDPE collector grid pumping leachate directly into dedicated MEE/ATFD thermal treatment units.

Ambient & Groundwater Monitoring: Upgradient and downgradient monitoring piezometers with quarterly GPCB certified lab testing.

Facility #2

Stripper Column Pre-Treatment Unit

The Stripper Column system acts as the critical frontline pre-treatment unit for high-COD industrial wastewater containing volatile organic compounds (VOCs), low-boiling solvents, ammonia, and light hydrocarbons. By extracting these volatiles upstream, it prevents fouling in MEE evaporators and ensures maximum energy efficiency.

Volatile Stripping Efficiency: Removes >95% of VOCs, alcohols, ketones, and chlorinated solvent fractions.

Downstream MEE Protection: Drastically reduces scaling, foaming, and organic carryover into the evaporator condensate.

Closed Vapor Condensation: Overhead condensers capture volatile organic vapors into decanters for safe solvent recovery.

Corrosion-Resistant Column Internals: Constructed with SS316L / Hastelloy-C packing for aggressive acidic or alkaline feeds.

Facility #3

Common Multiple Effect Evaporator (MEE)

Our Common MEE facility is the technological core for treating recalcitrant, high-TDS wastewater streams. Utilizing a quadruple-effect thermodynamic cascade with forced circulation calandrias, it concentrates dissolved solids up to saturation limits while recovering high-purity process water for Zero Liquid Discharge (ZLD).

Quadruple-Effect Energy Efficiency: Vapor reuse across consecutive stages reduces specific steam consumption to <0.28 kg steam / kg water evaporated.

High TDS Capability: Handles aggressive raw feeds with Total Dissolved Solids from 20,000 ppm up to 150,000 ppm.

Forced Circulation Calandrias: High fluid velocity prevents salt scale crystallization on heat exchanger tube walls.

High Purity Condensate Recovery: Recovers up to 90% reusable distillate (TDS < 100 mg/L) for industrial cooling towers or boilers.

Facility #4

Agitated Thin Film Dryer (ATFD) Facility

The Agitated Thin Film Dryer (ATFD) is the indispensable bridge between concentrated MEE liquid effluent and final solid salt disposal. Utilizing high-speed rotor blades within a steam-jacketed cylindrical body, it mechanically spreads slurry into an ultra-thin turbulent film, driving off remaining moisture to produce free-flowing crystalline salt cake.

Complete Moisture Removal: Converts sticky viscous slurry (40-50% TDS) into solid salt cake with <5% residual moisture.

Anti-Fouling Self-Cleaning Action: Hinged rotor scrapers continuously sweep the inner heat-transfer wall, preventing product baking or crusting.

Continuous Automated Discharge: Solid salt cake is discharged via synchronized rotary air-lock valves directly into TSDF containment bags.

Heavy Metal Encapsulation: Precipitates toxic inorganic salts into stable dry crystalline minerals safe for TSDF landfilling.

Facility #5

Common Spray Dryer Facility

Our industrial Spray Drying facility provides rapid, single-step thermal atomization drying for high-COD, high-TDS liquid effluent streams that are unsuitable for conventional heat exchangers. Liquid feed is pulverized into micro-droplets inside a co-current hot gas drying chamber, achieving instant moisture flash vaporization and producing dry inert powder.

Instantaneous Flash Vaporization: Millisecond contact time between atomized droplets and 350°C hot air prevents product thermal degradation.

High-Speed Rotary Atomizers: Precision variable-frequency atomization discs spinning up to 18,000 RPM for uniform droplet size distribution.

Multi-Stage Particulate Scrubbing: High-efficiency cyclonic separator combined with reverse pulse-jet Bag Filter and wet venturi scrubbers.

Zero Hazardous Effluent Runoff: Complete thermal liquid conversion ensuring zero liquid discharge from the drying line.
