Membrane technology in controlling micropollutants and pathogens

Membrane technology in controlling micropollutants and pathogens

The challenge posed by micropollutants and pathogens has been the subject of considerable interest over the past few decades. Our online event 'Discussing membrane technology: micropollutants and pathogens' event was held on 14 April 2021, in which Simon Judd and Graeme Pearce hosted a discussion with 30 delegates worldwide on the subject.

The disinfection capability of MBRs: credit where credit’s due

The disinfection capability of MBRs: credit where credit’s due

Disinfection by MBRs. Unlike regular physical membrane filtration, virus removal by MBRs is not limited to simple size exclusion. Adsorption onto the sludge solids and the membrane cake layer (as well as the membrane itself) represent important removal mechanisms, as well as removal by predation (the feeding on the pathogens by other higher organisms).

Designing and managing wastewater treatment plants using CAE software − the LynxASM1 modelling and simulation tool

Designing and managing wastewater treatment plants using CAE software − the LynxASM1 modelling and simulation tool

Ever more versatile and sophisticated options for designing and managing plants are being developed. And as the new CAE tools become more accessible and widespread, suppliers continue to develop and refine the tools, so the reliability of their predictions increases – promoting further take-up.

Reuse of dairy wastewater treated by membrane bioreactor and nanofiltration: technical and economic feasibility

Reuse of dairy wastewater treated by membrane bioreactor and nanofiltration: technical and economic feasibility

A study carried out by Andrade and co-authors assessed the viability of a two-stage membrane bioreactor−nanofiltration scheme (MBR−NF) for treating dairy wastewater. Of key concern was the quality of the treated water with respect to its potential reuse and the overall cost of the scheme.

Kunming Underground MBR: a Chinese case study

Kunming Underground MBR: a Chinese case study

China features many of the largest municipal wastewater MBRs in the world. Apart from their capacity, some also are ambitious in their construction. The below-ground installation at Kunming City, commissioned in 2012, is one such example. At an ADF (average daily flow) capacity of 150,000 m3/d and a peak daily flow of 195,000 m3/d, it is a substantial plant.
