Aeration and mixing solution for wastewater treatment process

23 January 2017

Landia’s AirJet is playing a key role in an aeration and wastewater system for a major poultry processor, based in the Kingdom of Saudi Arabia. 

Specified by MSA Environmental, a total of 39 dry-mounted Landia AirJets handle aeration, anoxic tanks and sewage at the remote site. 

Serving a new effluent treatment plant utilising membrane bioreactor (MBR) technology which treats wastewater from the poultry and rendering plants the AirJets keep wastewater aerated and mixed in two 800m3 balance tanks prior to Dissolved Air Flotation (DAF). In the two 130m3 DAF sludge tanks, AirJets keep the tanks’ contents fresh and homogenised prior to further treatment by a tricanter centrifuge.

AirJets are also utilised for two biological sludge tanks, aerating and mixing to provide homogenous composition to sludge dewatering equipment.  The units have also been installed in anoxic tanks for mixing purposes, as well as in the sewage treatment plant.

Commenting on the solution, Jerad O’Pray, director at MSA Environmental, said: “We have specified AirJet on many of our plants and always found them to deliver very good performance, as well being robust and reliable. This includes, for example, many years of highly effective operation at the Almarai CPP (dairy/juice) site in Al Kharj, also in Saudi Arabia.

“Despite ambient temperatures that are consistently above 40°C, the AirJets help reduce odour issues by keeping the tanks fresh during the near 24/7 operation”.

Comprising a chopper pump and an ejector system, AirJet is designed with an external knife system to ensure that the aerator does not get clogged up by any solids in the wastewater.
