Effluent challenges we solve, industry by industry

01

API & FormulationPharmaceuticals

Typical Effluent Contains

Organic compoundsSolventsAPIsFormulation chemicals

Pharmaceutical industries generate effluents containing organic compounds, solvents, active pharmaceutical ingredients (APIs) and chemicals used in formulation. Our solutions remove contaminants and ensure high-quality effluent suitable for discharge or reuse, in compliance with stringent pharmaceutical standards.

Our Solutions

  • Multi-stage filtration
  • Biological treatment
  • Reverse osmosis
  • Disinfection
  • Advanced oxidation
  • Zero Liquid Discharge
02

Dyeing, Washing & FinishingTextile

Typical Effluent Contains

DyesSurfactantsBleaching agentsProcess chemicals

Textile industries produce effluents laden with dyes, surfactants, bleaching agents and other chemicals from dyeing, washing and finishing processes. Our advanced treatment ensures cleaner effluents, water recovery and reduced environmental impact.

Our Solutions

  • Colour removal – activated carbon / ozonation
  • Biological treatment
  • Membrane filtration (RO)
  • Zero Liquid Discharge
03

Pulp & Paper MillsPulp & Paper

Typical Effluent Contains

Organic matterSuspended solidsLigninChlorine compoundsSulphides

Effluents from pulp and paper mills are typically high in organic matter, suspended solids and chemicals such as lignin, chlorine-based compounds and sulphides. Our solutions minimise pollutants and meet environmental discharge regulations.

Our Solutions

  • Primary clarification
  • Aerobic / anaerobic treatment
  • Chemical dosing for sulphur & lignin
  • Advanced filtration
04

Boiler Feed & CoolingThermal Power

Typical Effluent Contains

Suspended solidsDissolved saltsSilicaCooling tower chemicals

Water treatment is crucial in thermal power plants – particularly maintaining low silica levels in demineralised water for boiler feed. Effluents arise from cooling towers, boiler feed systems and chemical cleaning. We design efficient systems that ensure optimal performance, reliability and water reuse.

Our Solutions

  • DM water with low silica
  • Coagulation-flocculation
  • Biological treatment
  • Membrane filtration
  • Zero Liquid Discharge
05

Drilling & RefiningOil & Gas

Typical Effluent Contains

HydrocarbonsHeavy metalsSaltsProduced water

Effluent from oil and gas operations often contains hydrocarbons, heavy metals, salts and produced water from drilling and refining. Our treatment ensures safe disposal or reuse while complying with environmental regulations.

Our Solutions

  • Oil-water separation (API / coalescers)
  • Reverse osmosis desalination
  • Electrocoagulation
  • Advanced oxidation (AOP)
06

Refining & Chemical ProductionPetrochemical

Typical Effluent Contains

Organic chemicalsSolventsOilsHeavy metals

Petrochemical industry effluents are typically rich in organic chemicals, solvents, oils and heavy metals from refining and chemical production. We design treatment systems that make treated water suitable for reuse or safe discharge.

Our Solutions

  • Activated carbon adsorption
  • Biological treatment
  • Membrane filtration
  • Chemical precipitation
07

Processing & FermentationFood & Beverages

Typical Effluent Contains

Organic wasteOils & fatsDetergentsHigh BOD

Effluents from food and beverage plants contain organic waste, oils, fats, detergents and high BOD (biological oxygen demand) from cleaning, cooking and fermentation. We treat wastewater effectively for discharge or reuse in the production process.

Our Solutions

  • Dissolved air flotation (DAF)
  • Activated sludge / anaerobic digesters
  • Advanced filtration
  • Water reuse
08

Chemical ManufacturingChemical

Typical Effluent Contains

AcidsSolventsHeavy metalsOrganic compounds

Chemical manufacturing produces effluents that can contain a wide range of contaminants. Our solutions treat wastewater to meet regulatory standards and minimise environmental impact.

Our Solutions

  • Chemical neutralisation
  • Heavy metal precipitation
  • Activated carbon filtration
  • Reverse osmosis
  • Biological treatment
