Linde LLC will introduce a new oxygen recovery system which dramatically reduces oxygen (O2) consumption during ozone (O3) production for water treatment at WEFTEC 2018 in New Orleans on 1st to 3rd October.
The OZORA™ oxygen recovery system, jointly tested and validated with SUEZ at a drinking water treatment plant, significantly lowers ozonation operating costs and will be unveiled at booth 7313 during the Water Environment Federation’s (WEF) Annual Technical Exhibition & Conference at New Orleans Morial Convention Center, LA.
Ozone generators typically convert about 10% of O2 used in the process to O3, but the new system efficiently separates O3 and recycles the unused O2 back to the O3 generator, significantly reducing O2 consumption by up to 60%.
Ozonation is a water treatment process which helps utilities improve filtration and disinfection.
“This innovation is important not just for drinking water treatment facilities currently using ozonation, but also for those considering new ozonation systems,” said Peter Studer, Linde’s programme manager for water treatment.
“Ozonation improves filtration and addresses concerns about chlorine disinfection by-products and micropollutants. The OZORA system brings this higher level of technology within reach and makes it more affordable.”
Linde will also introduce two exclusive portable solutions – SOLVOX® and SOLVOCARB® – for supplemental treatments at WEFTEC.
SOLVOX® Mobile is an oxygenation unit which helps wastewater plants cope with peak loads, maintenance downtime or replacement of aeration equipment, while SOLVOCARB® Mobile is a carbon dioxide (CO2) injection unit for efficiently controlling the pH of water. Using CO2 for alkalinity control avoids the safety hazards and overtreatment issues associated with mineral acids.
The Tier One company also supplies bulk O2 and nitrogen gases for O3 production, as well as bulk O2 and CO2 for municipal and industrial water and wastewater treatment.
