Wastewater Treatment Tanks & System

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 300mg/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 dischargedas 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 membrane tank.

A fully automated system, the nrPUR™ platform is designed to provide many years of reliable, effective and affordable treatment of water and wastewater.

Membrane BioReactor Process

Wastewater Treatment Process

Wastewater is centrally collected and pretrated to remove non-biodegradable solids and transferred to an equalization tank, where variations in flow and concentration are moderated. The balanced wastewater is transffered under level control to the system’s BioReactor. Wastewater is recirculated between the BioReactor and  the membrane tank at a rate of 4-5 times average daily flow.

The bioreactor is a continuously-stirred, complete-mix reactor designed to ensure effective biological digestion of the organic materials in the secondary aeration step of the activated sludge process. The appropriate BioReactor volume is dictated by the F/M ratio and the mass loading of BOD per cubic volume of reactor.

The activated sludge process converts the soluble organic material present in the wastewater into CO2, H2O and biological cell mass. An aeration system provides the oxygen required for this process. The mass of oxygen transferred is based upon the design daily influent BOD load.

The liquid phase of the mixed liquor is pulled through the membrane at a predetermined rate, or flux, established for each specific application. The mixed liquor suspended solids (MLSS) are rejected and moved away from the membrane by the air scour and hydraulic action. Permeate is drawn through the membranes under suction by permeate pumps and discharged to a clean water storage tank or for further polishing.

Typical Sytem Results:

  • BOD: <5 mg/L
  • TSS: <5 mg/L
