Industries & Wastewater Applications
Solutions Developed Around Your Wastewater Stream
GRELLIX evaluates wastewater composition, daily volume, scaling and corrosion risks, required water quality and disposal economics before selecting evaporation, crystallization or an integrated ZLD process.
Common Industrial Applications
No two industrial wastewater streams are identical. The examples below describe common starting points; final process selection requires water analysis and, for complex streams, bench or pilot testing.
Metal Finishing & Electroplating
Electroplating Wastewater Treatment →
Electroless Nickel Wastewater Treatment →
Rinse water, plating bath drag-out, electroless nickel wastewater and mixed-metal streams. Key issues include heavy metals, complexing agents, chlorides, scaling and hazardous-waste cost.
Machining & Cutting Fluids
Cutting Fluid Wastewater Treatment →
Oily emulsions, coolants, wash water and floor-cleaning wastewater. Pretreatment may be required to manage free oil, foaming and volatile organics before evaporation.
RO Reject & High-Salinity Brine
High-Salinity Wastewater Treatment →
Concentrate membrane reject, regeneration wastewater and brines when further membrane recovery is limited by osmotic pressure, scaling or salt saturation.
Electronics, PCB & Semiconductor
PCB Wastewater Treatment →
Semiconductor Wastewater Treatment →
Segregated high-strength streams, metal-bearing wastewater and selected process concentrates. Feed segregation and material compatibility are especially important.
Lithium Battery & New Energy
Lithium Battery Wastewater Treatment →
High-salt process wastewater, cleaning streams and resource-bearing liquids. Process design depends on fluoride, ammonia, solvent and mixed-salt composition.
Chemical & Pharmaceutical
Chemical & Pharmaceutical Wastewater Treatment →
Mother liquor, reactor and tank wash water, intermediate wastewater and heat-sensitive concentration. Volatile organics must be evaluated before distillate reuse.
Biotechnology & Food Processes
Low-temperature concentration of selected process liquids and product streams, with sanitary or food-grade materials available where required.
Resource Recovery & ZLD
Integrated pretreatment, evaporation, crystallization, solid-liquid separation and polishing for water reuse, material recovery and minimum liquid discharge.
Choose the Process by the Required Output
Vacuum Evaporation
For wastewater volume reduction, distillate recovery and process-liquid concentration.
Scraped Crystallization
For high-salinity, scaling, viscous or crystallizing streams requiring further concentration.
Integrated ZLD
For projects combining pretreatment, evaporation, crystallization, water polishing and solids management.
