For many industries, water is crucial during the manufacturing process. High quality and local water can even be a key feature of your brand. After use during production, waste water has to be treated to ensure compliance with discharge consent conditions, minimise environmental pollution and reduce costs. The treatment is often performed in trickle filter beds which use a plastic fill media. When these filter beds are refurbished or decommissioned, BM Tech can help with a best practise recycling solution, helping you avoid landfill.

Plastic fill media is a honeycomb type of structure designed to create a very large surface area for biological treatment of your industrial effluent water. The media is often in large blocks, frequently described as “pack”. Plastic fill media is made from either uPVC or, in more recent installations, Polypropylene. The fill media has a working life of typically around 25 years.

By the end of life, the pack material is heavily contaminated. In the past this made it too hard to recycle and used material was sent to landfill.  BM Tech is able to recycle uPVC from plastic fill media, therefore supporting our client’s environmental requirements and helping to improve environmental target achievement by Reducing, Reusing and Recycling this material. No longer can Landfill and Energy from waste options for this kind of media be considered as best practice.  No matter how big or small your trickle filter beds, please call us on 07947 352934 to find out how we could help you. We would be delighted to discuss best practise ideas to ensure efficient operations.
