Aeration of waste water

Mechanical aeration is an important component in biological treatment of waste water.  Aerobic biological systems are required if the COD concentration of the desired water quality is to be anything under 1000 mg/l. There are numerous factors that determine the amount of air required, these being typically;

• COD and ammonia load (for design purposes these parameters are measured in kg/d)
• Height above sea level
• Operating temperature
• Geometry of tank and water depth
• Choice of equipment
  • Side Channel Blowers

For high organic loading rates, HWT makes use of a blower and diffuser dome arrangement.  Typically, the delivery rate of this type of aeration system, at the selected water depth, is approximately 2kgO/kWhr.

An air diffuser or membrane diffuser is an aeration device typically in the shape of a disc, tube or plate, which is used to transfer air and with that oxygen into the sewage or industrial wastewater

Bubble diffusers are crucial in wastewater fine bubble aeration and treatment processes. They allow wastewater treatment systems to push air bubbles through water pipes and feed the tank's microorganisms that process the water.
