The nrPUR Membrane platform is a low-energy, self-cleaning ultrafiltration (UF) system for the treatment of low- to high-strength wastewater to high-quality discharge or reuse standards. The technology is highly flexible and suitable for both domestic and industrial wastewater, from a wide range of applications that include hotels & resorts, small communities, craft breweries, wineries, dairy and other wastewater. Configured around a series of modular process building blocks, nrPUR easily integrates into advanced biological treatment systems (i.e. Membrane Bioreactor (MBR), MBBR, MABR, etc) to provide effective TSS & BOD5 reduction of >95% on wastewater streams from 300 mg/L to 10,000 mg/L, producing safe, reuse-quality water. When combined with our advanced polishing technologies the nrPUR system can treat trace micro pollutants (e.g. Phosphorus, Ammonia, etc) to safe discharge levels.
The nrPUR UF membrane racks are submerged in the water to be treated and connected to the permeate extraction system. All suspended solids and micro-organisms larger than the membrane pore size, typically less than 0.1 µm in size, will be rejected by the membranes and only clean, solids-free water will be discharged as permeate. The permeate can then be discharged, or sent for reuse or further polishing steps.
On a continuous basis, air is bubbled from a grid of diffusers installed at the base of the nrPUR racks, acting as a scouring mechanism to reduce the potential for biofouling on the surface of the membrane and to enhance the mixing of the biomass within the membrane tank.
A fully automated system, the nrPUR platform is designed to provide many years of reliable, effective and affordable treatment of water & wastewater.

In addition to our Submerged UF Membrane solutions for wastewater treatment, Enereau also has wide range of options for both pre- & post-treatment. These solutions include pH adjustment, pre-screening (fine screen, floatation, etc) to final polishing of reuse water with UV disinfection, carbon filtration, etc. Whether deployed as stand-alone units to achieve municipal discharge targets or as a complete treatment platform to achieve onsite reuse our smart modular technologies can help your site achieve its wastewater and water reuse objectives.
