We have been granted approval by the Drinking Water Inspectorate (DWI) to provide robust solutions to water utilities and municipal markets, empowering them to strengthen their resilience planning, mitigate risks effectively, and ensure unwavering compliance with regulatory requirements.
Envirogen’s Deltapor filter cartridge options, including the Municipal Water (MW) and Municipal Water Absolute (MWA) depth filters, are specifically designed and manufactured for drinking water applications. These cartridge filters have obtained DWI approval (DWI 56.4.1274) due to their exceptional performance in water production, guaranteeing the efficient production of safe and pure drinking water. Our filters offer a hassle-free installation and user experience, allowing seamless integration with our DWI approved CF stainless-steel cartridge filter housings range (DWI 56.4.1257). Furthermore, they can be easily retrofitted to any standard filter housing, facilitating quick and convenient changeovers.
Deltapor MW and MWA depth filters have been specifically developed to deliver safe, reliable, and cost-effective filtration. These filters excel in removing various particulate matter, such as sand, silt, and organic material, and are validated for Cryptosporidium and Clostridium retention grades. Our Drinking Water Inspectorate approved Deltapor manufacturing technology ensures the creation of depth filter cartridges with a high void volume, enabling high throughputs, minimal pressure loss, a large dirt capacity, and an extended on-stream lifespan. With a removal rate exceeding 99.98%, the Deltapor MW and MWA filter cartridges significantly reduce turbidity, safeguarding subsequent treatment processes, including membrane filters, and contribute to the fulfilment of drinking water safety standards.
Envirogen DWI approved filtration system in action
Client Needs: A prominent water supply company in Northern England recognised the potential risk of elevated turbidity levels upon start-up in six boreholes sourced from two separate locations. Addressing this concern was crucial as it could impact the water treatment process and potentially compromise the quality of water distributed through the network.
Our Solution: Following a thorough evaluation of various potential solutions, the water company opted for Envirogen’s specifically designed DWI Reg-31 approved CF filter housings, which incorporate Deltapor MWA filter cartridge technology. This choice was made to effectively control turbidity and ensure optimal water quality.
The Results: The six boreholes were linked to a common water treatment plant by a network of pipes, this enabled a maximum of 25 million litres of water per day to be achieved, resulting in enhanced efficiency, and delivering notable performance and commercial advantages.
