INFRACORP WATER

InfraCorpProcess Water Treatment Technologies

Process water is any water used in industrial or commercial processes, excluding domestic uses like drinking or sanitation. The treatment goal is to ensure water quality is consistent with the operational requirements of the system ,whether that means preventing scaling, corrosion, fouling, or contamination.

Process water treatment ensures that water meets the precise quality standards required for a manufacturing, production, or power generation process.

The treatment steps are highly customized based on the source water and the intended use.

 

Key Differences from Wastewater Treatment:

Goal: Wastewater treatment aims to protect the environment; process water treatment aims to protect the industrial process and final product.

Focus: Removing specific impurities that could cause scaling, corrosion, bacterial growth, or product contamination.

Source Water: Can be from a municipal supply, well, or surface water (river/lake).

Common Problems Process Water Treatment Solves

    1. Scaling: Caused by dissolved minerals like calcium and magnesium (hardness). Scale builds up on heat exchangers and pipes, reducing efficiency and causing clogs.
    2. Corrosion: Caused by dissolved oxygen, low pH, or certain ions. Corrosion damages pipes, tanks, and equipment.
    3. Fouling: Caused by suspended solids, silt, or organic matter that deposit on surfaces.
    4. Microbiological Growth: Bacteria and algae can form biofilms (slime), leading to contamination, clogging, and health risks (e.g., in food/beverage).
    5. Product Contamination: Any impurity can affect the color, taste, texture, or purity of the final product

Pretreatment / Make-up Water Treatment

This is the initial treatment of raw water before it enters the process loop.

  • Screening & Filtration: Removes large suspended solids and silt.
  • Multi-Media Filters: Use layers of anthracite, sand, and garnet to remove particles down to ~10-20 microns.
  • Softening: Removes hardness ions (Calcium & Magnesium) to prevent scaling.
  • Ion Exchange Softeners: Use a resin to swap calcium and magnesium ions for sodium ions.
  • Reverse Osmosis (RO): The workhorse of high-purity water treatment. Forces water through a semi-permeable membrane, removing >99% of dissolved salts, organics, and bacteria. Produces permeate (very pure water) and concentrate (reject water).
  • Deaeration / Degasification: Removes dissolved gases, especially oxygen and carbon dioxide, to prevent corrosion.
  • Chemical Addition: Dosing of chemicals like scale inhibitors, corrosion inhibitors, and biocides.

Typical Process FlowOf Process Water Treatment

  1. Pre-Treatment

Removes suspended solids, turbidity, and organic matter.

  • Coagulation / Flocculation
  • Clarification / Sedimentation
  • Filtration (Sand, Multimedia, or Cartridge)
  • Activated Carbon Adsorption
  1. Primary Treatment

Adjusts basic chemistry and hardness.

  • Softening (Ion Exchange or Lime Softening)
  • pH Adjustment / Chemical Dosing
  • Dechlorination or Chlorination (as required)
  1. Advanced / Secondary Treatment

Removes dissolved solids and fine contaminants.

  • Reverse Osmosis (RO)
  • Nanofiltration (NF)
  • Electrodeionization (EDI)
  • Deionization (DI)
  • Ultrafiltration (UF)
  1. Polishing / Conditioning

Fine-tunes water to meet ultra-pure or process-specific requirements.

  • UV Sterilization
  • Ozone Treatment
  • Final Ion Exchange or Resin Polishing
  • Degasification (CO₂ / O₂ removal)

Importance of Process Water Treatment

    1. Product Quality: Ensures consistency, safety, and purity of the final product.
    2. Asset Protection: Prevents scale and corrosion, dramatically extending the life of boilers, cooling towers, and process equipment.
    3. Operational Efficiency: Maintains heat transfer efficiency, reduces downtime for cleaning and descaling, and minimizes energy consumption.
    4. Cost Savings: Reduces water consumption (through recycling and efficient blowdown), chemical usage, and maintenance costs.

Process water treatment refers to the purification and conditioning of water used directly in industrial processes — such as manufacturing, cooling, heating, or product formulation — to meet specific quality and performance standards required by each application.
