Ozone for Waste and Wastewater
Ozone generation from pure oxygen for wastewater treatment
(hard COD removal & biodegradability increase)
Ozone can be added at several points throughout the wastewater treatment plant, such as pre-oxidation, intermediate oxidation or final disinfection.
Ozone is an unstable product that cannot be stored and needs to be produced on-site from oxygen through dedicated generators. BIG as an oxygen major supplier has over the years developed the know-how to help its customers optimize the ozone processes.
Oxygen vs Air for Ozone Production
The use of pure oxygen to produce ozone allows higher concentrations in the feed gas, which provides higher solubility
Less Energy Consumption
Pure oxygen provides direct cost savings vs. air in ozone production by reducing the power requirement by 2.5x
Less Maintenance Costs
Pure oxygen is compatible with any ozone generator. It provides longer life and maintenance cost savings
Flexible Design
The use of pure oxygen delivers useful generation flexibility required in any water treatment process
pH Control and Neutralization
A proven technique to efficiently control the pH of water by the addition of carbon dioxide
Are you interested in achieving an accurate pH control in a safe way?
The most frequent pH reducers are mineral acids. An excellent alternative is carbon dioxide, which offers many advantages over the mineral acids, especially with regards to safer handling and healthier conditions for users.
At BIG, we understand the difficulties of neutralizing water and wastewater pH. That is the reason why we have developed new optimized equipment to enhance the use of CO₂ and its benefits.
BIG Expertise in Neutralizing Water/Wastewater pH
Safer Working Conditions
Decrease the risk of burns, poisonous fumes and other hazards that result from the handling of mineral acids
Accurate pH Control
No overdose takes place when using CO₂, so the risk of excessive acidification, through the use of strong acids is prevented
Quickly Reduces High pH Levels
Continuous, automated process controls help to balance the corrosive scaling of water
Cost Effective
Low initial investment and operating costs
