About Suprafilt

Suprafilt designs, manufactures and installs aeration systems for the wastewater treatment sector. Its offer covers a full turnkey solution, including in-house design and fabrication, with product lines such as complete aeration solutions, fabricated items, mixers, liftable grids, diffusers, Nereda internals and oxidation ditches.

Customers include water companies such as Anglian Water, Welsh Water, South West Water, Scottish Water and Yorkshire Water, as well as industrial sites such as drinks processing and paper plants. Revenue comes from supplying and installing these systems on projects. The company was the first in the UK to market a fine bubble diffuser from SSI, and it is one of the industry leaders for installing Nereda systems.

Suprafilt was founded in 2002 and is based in Rossendale, Lancashire. The business traces its origins to 1995, when it was formed as Suprafilt Coates, a joint venture with Coates Engineering. In 2024 it became part of the Aerzen Group. The company has worked on projects outside the UK, including Sharjah in the UAE.

Product: Wastewater aeration systems, including fine bubble diffusers, liftable grids, mixers, Nereda internals and oxidation ditches, supplied as turnkey projects with installation.
