Algae in Waste Water Treatment

Algae in waste water treatment facilities as important bioremediation agents.

Bioremediation can be defined as a process which

  • Uses metabolism abilities of microorganisms to remove pollutants and contaminants.  Algae have tremendous potential to be used for waste water remediation and using algae in a wider scope compared to current commercial use is being emphasized.

Combining algae for waste water remediation with biofuel production is an economically feasible process. The waste water treatment plants are an invaluable source of algal biomass which serve as a bright prospect for many industries and companies that use algae as a feedstock for a variety of purposes.

Industries using algae for commercial purposes include meat and poultry industry, paper and textile industry, industries using dyes and pigments, breweries, pharmaceuticals, bio-fertilizer production units and metal finishing industries.  Other industries include:

  • Poultry
  • Dairy
  • Aquaculture
  • Textiles
  • Pulp and Paper
  • Distillery & Breweries
  • Leather
  • Foods
  • Petrochemicals
  • Pharmaceuticals
  • Chemicals
  • Mining
  • Metalworking

The composition of effluent from industries is a lot different from the composition of domestic wastes. Treatment of industrial effluent is targeted at the removal of excess concentrations of nitrogen, phosphorus and other organic matter.

Algae are used for waste water treatment as they remove undesirable substances by biodegradation. Organic matter in water is broken down to smaller components such as CO2, ammonia and phosphates.
