Air Pumps for Waste Water Treatment

Waste water treatment plants come with many different operating systems, but for many waste water treatment plants an air pump is the power house of the system, providing air to the tank to produce the right conditions for the bacteria live, grow and to break down the waste. Without a properly working air pump your system may develop problems such as smells, sludge build up, clogging, and partially treated waste passing to your percolation area.

Delaney Concrete uses Hiblow XP 80 pumps in our new Bio-Crete installations as they are a low energy pump with a relatively long life span. Unfortunately, like all electrical motors, air pumps don’t last forever, and from time to time they need to be replaced. Delaney Concrete stocks a range of air pumps which should suit most types of wastewater treatment systems.

Air pumps are sized by the amount of air they pump in a given time. When you look at your existing air pump you’ll see a number on the casing. The most common size of pump is 80 litres of air per minute, so you’ll often see pumps with ET 80, EL 80, HP 80, etc., but 60 litres of air per minute or 100 litres of air per minute are also not unusual.  We use 80 litre air pumps in all our Bio-Crete wastewater treatment plants, but different systems may use other sizes.

There are also two different types of air pump motors. The majority of air pumps use diaphragms to pump the air, but piston pumps are also available. Piston pumps tend to have a longer lifespan than diaphragm pumps, but they should only be used in areas where flooding is not an issue. Both pumps need access to clean air, and should never be allowed to circulate the stale air in your tank as this can clog filters and shorten the lifespan of the pump.

Tips for Fitting Air Pumps

Air pumps should be simple to fit, just swap out the old one and reconnect in the new one, the

connections should all be the same, however there are a few things you should look out for:

  • Ensure that your air pump can draw in clean, fresh air. Recirculating dirty air from your wastewater tank will clog filters and can shorten the life of your air pump.
  • Ensure the air pump is housed above the water level of your tank so that it won’t flood.
  • Ensure all connections are tight so the air is getting to where it needs to go.
