Ozone Generator in Waste Water Treatment

Econo-Watd Ozone System has been successfully implemented for wastewater treatments such as applications in Sewage Treatment Plants (STP). Ozone system for industrial application promotes cost-effectiveness and improves efficiency of the facility, at the same time promotes compliance with regulations.

The typical setup is shown below:

Major Benefits include -

• Reduction of sludge by up to 50%
• Reduced BOD and COD by up to 90%, thereby promotes environmental conservation
• Increased filter efficiency
• Effectively kills microorganisms (bacteria, molds, etc) compared to conventional systems that use chemicals
• No harmful residues, and increased dissolved oxygen in effluent. Ozone needs only a short contact time of 10-30 minutes, and then it decomposes rapidly to oxygen
• Reduced costs
  • Avoids problems on purchasing and storing chemicals (like chlorine)
  • Consumes lower energy (compared to UV disinfection, which is another alternative to chlorination)
  • Reduces cost of freshwater supply as the system improves water quality for recycling
• Environmental-friendly and helps conform to authority regulations by reducing BOD and COD levels of the water discharged; at the same time, avoiding chemical usage.
• Improves color, taste, and odor by oxidation of tannins and lignins, and by removal of volatile fatty acids, sulfides, ammonia and other compounds
• Oxidation of heavy metals and neutralization of pollutant by-products such as cyanide, lead, nickel, cadmium, iron, etc.
• Helps reduce detergents in wastewater

Before and after tests show significant improvement in water quality:
