Water and waste water treatment

Most effective blower technology for wastewater

Water and wastewater treatment

There are many options to apply methods to avoid damaging the environment. In the case of wastewater e.g. the ventilation of the sediment tank or the pressure ventilation of biological wastewater treatment systems. The oxygen introduction is important, for deep wastewater tanks, wastewater treatment systems with standard aeration tanks or natural clarification ponds alike.

If the wastewater has already entered the natural cycle, ventilating lakes and rivers prevents additional contamination. When treating drinking water, rinsing the filters with compressed air ensures that perfect water is provided and natural water reserves are not used excessively.

Gas which occurs on landfill sites, digestion towers or gas which is produced when treating wastewater does not escape into the environment anymore or is not just burned. It is used sustainably to create energy to relieve the environment and remedy resource deficits. Due to the pressure increase of biogas blowers, the gas is transported to CHPs or generators where the converted energy can be used to heat buildings or greenhouses, for example. The produced gas is measured by AERZEN rotary piston gas meters.

During sludge drying processes, AERZEN positive displacement blowers can be used for the subsequent pneumatic transport of the dried sludge.

AERZEN products not only do their job in the examples given above. Just as there are many options to protect the environment, there are many areas of application for AERZEN positive displacement blowers, rotary lobe compressors and turbo blowers.



Late on a Wednesday afternoon we received a message from our French depot manager that a disaster had taken place in a sewage treatment plant ca. 50 km from Paris. The aeration system of a biological sewage water treatment plant had failed threatening the lives of millions of microbes used to treat the sewage.
