Howden, a leading global provider of mission critical air and gas handling products, technologies and services, has been awarded a contract to supply four high speed single stage integrally geared blowers and a control system for the new Athlone Wastewater Treatment Works (WWTW) located in Cape Town, South Africa.

The City of Cape Town is growing rapidly due to population growth and migrations, which triggered the need for the WWTW to upgrade to ensure it can meet increasing demand to clean the water and make it safe before discharging it into the environment. The City has identified upgrades to the Athlone WWTW, which has been treating wastewater since the early 1920s. This critical investment into key infrastructure improves environmental health where the effluent from the WWTW must meet stringent health and safety standards to ensure that there is no harm to biodiversity of the established water stream.

Howden supplies high-efficiency blowers and compressors, and advanced digital solutions for smart aeration systems

Howden's high efficiency SG Blowers and proprietary Bio-Active Response System (BARS), scheduled for installation in 2024, will support the WWTW by efficiently delivering the correct amount of dissolved oxygen, reducing the electrical demand and generating energy savings. Howden's Combined Vane Control systems, which integrates the Inlet Guide Vane and Variable Vane Diffuser, will work in conjunction with a Howden algorithm to deliver the most efficient air required over a large turndown range (100-45%).

Eric Vemer, President and General Manager of Africa & Middle East at Howden, said: "Howden has supported the City of Cape Town over the past ten years. We have worked together to optimise its Fine Bubble Diffuser Aeration systems, which consume around 30-50% of the energy requirements for a Waste Water Treatment Plant.

"The Howden team designed a customised solution that met the client's stringent specifications to optimise energy consumption. This goes over and beyond the requirements of an OEM. We work hand in hand with our clients to solve real world problems."

Howden supplies high-efficiency blowers and compressors, and advanced digital solutions for smart aeration systems. With Howden's aeration system design, overall energy is minimised, and high reliability is guaranteed, which saves time and improves operating cost. Howden supports its equipment through an aftermarket workshop in Cape Town to ensure reliability and minimum downtime through 24/7 availability of the service team.
