Wastewater Treatment

High efficiency blowers and compressors and innovative digital solutions for advanced, efficient aeration systems

Wastewater treatment is required to manage effluent from municipal sewage systems and from many industrial processes where liquid organic effluents are produced as a by-product.

The demand for treatment plants is growing quickly in many countries as waste volumes increase with population growth and the focus on environmentally sensitive disposal intensifies.

With aeration accounting for over 60% of power requirements, it is essential to make sure you get an efficient solution. Our rotary blower and turbo compressor technology has been reliably serving wastewater applications for many decades, and with the added benefit of our Data Driven solutions we can recommend the most appropriate operational changes to optimise the performance of your rotating equipment.

Smart aeration

Enhancing wastewater solutions with the combination of Uptime, offering a unique and innovative digital solution for the performance optimisation of your equipment.

Products: Uptime

Grit chamber aeration

Removing grit from wastewater is an initial treatment stage and aerated chambers can be used to separate out and settle the grit at the bottom of the chamber. Air is supplied to the chamber by blowers.

Products: EasyAir Rotary, Roots Rotary Lobe Blower

Diffused aeration

Biological wastewater treatment using diffused aeration requires the injection of air into the wastewater to oxidize organics and aid the bio-degradation of pollutants. Howden has a wide range of blower and compressor technologies available for every capacity, flow rate and efficiency requirement.

Products: EasyAir Rotary, Roots Rotary Lobe Blower, EasyAir Turbo, KA Series

Membrane Air Scouring/Backwash

Membrane BioReactor (MBR) systems are used in advanced wastewater treatment plant. The membranes are scoured by air supplied by blowers to reduce fouling.

Products: EasyAir Rotary, Roots Rotary Lobe Blower

Sludge Drying

Sewage sludge can be combusted on-site, shipped elsewhere for combustion or used as agricultural fertilizer. The larger plants and those in metropolitan areas opt for on-site incineration. Fluid bed combustors utilize blowers.
