Industrial Water Treatment

Artec Waters Industrial water treatment involves a variety of processes to manage and treat water used in industrial operations. These processes aim to ensure water quality for industrial use, protect equipment, comply with regulatory standards, and mitigate environmental impact. The treatment needs can vary greatly depending on the industry and specific applications

Dissolved Air Flotation

Purpose: DAF is used to remove suspended solids, oils, greases, and other particles from water.

Process:

Pre-treatment: Water is first treated with coagulants and flocculants to form larger particles (flocs).
Air Saturation: Air is dissolved in water under pressure.
Release and Flotation: The air-saturated water is released into the DAF tank at atmospheric pressure. The air comes out of solution, forming tiny bubbles that attach to the flocs.
Separation: The bubbles lift the flocs to the surface, forming a floating layer of sludge.
Removal: The sludge is mechanically removed from the surface, and the clarified water is discharged from the bottom of the tank.
Applications:

Wastewater treatment plants
Pulp and paper industry
Oil refineries and petrochemical plants
Textile and dye manufacturing
food

Membrane Bioreactor System (MBR)

Biological Reactor:

Where biological degradation of organic pollutants occurs, typically an aerated tank where microorganisms consume organic matter.
Membrane Filtration Unit: Consists of microfiltration or ultrafiltration membranes that physically separate treated water from the mixed liquor (biomass).
Types of Membranes:

Submerged (or Immersed) MBR: Membranes are submerged in the bioreactor tank. Water is drawn through the membranes by suction.
External (or Sidestream) MBR: Membranes are located outside the bioreactor. Mixed liquor is pumped through the membranes and returned to the bioreactor.

Applications:

Municipal wastewater treatment.
Industrial wastewater treatment (e.g., food and beverage, pharmaceuticals, textiles).
Water reuse and recycling projects.
