PRODUCT GUIDE

Kynar PVDF Jet Aerator For Improved Wear Resistance Kynar PVDF Jet Aerator For Improved Wear Resistance

Ten years ago, KLa Systems was presented with the challenge of finding a more wear-resistant material for our jet aeration nozzles.  The inner nozzle is the liquid propulsion nozzle of the jet aerator and continuously sees high volumes of motive liquid flow at velocities ranging from 33-46 ft/s.  Traditionally, these inner jet nozzles were made from the same FRP material as the outer jet with the industry accepted corrosion/abrasion liner made up of C-Glass/Nexus and Silicon Carbide impregnated into the vinylester resin.  For many years this material had held up in most industrial and municipal bioprocesses with no adverse deterioration or wear.

Municipal Wastewater Treatment Plants Benefits From Energy-Efficient ZS Screw Blower Municipal Wastewater Treatment Plants Benefits From Energy-Efficient ZS Screw Blower

In conventional wastewater activated sludge plants, millions of bacteria feed on organic waste, breaking it up into carbon dioxide, nitrogen gas and water. Because the bacteria need oxygen, large amounts of air are blown in the aeration tanks. The aeration blower system accounts for up to 70 percent of the energy usage in a typical biological wastewater treatment plant.

Screw Versus Lobe Technology Screw Versus Lobe Technology

The aeration blower system accounts for up to 70 % of the energy usage in a typical biological wastewater treatment plant. Thanks to, Atlas Copco's innovative oil-free screw blowers, you can save about 30% more energy compared to conventional lobe technology: a significant cost reduction!
