Microfiltration (CMF) is a technology that is very efficient for the clarification and disinfection of karstic waters for the production of drinking water. In Héricourt-en-Caux (Normandy), a Memcor® CMF plant is treating a particularly difficult water with a background level of turbidity... has been solved by injection of a coagulant and optimisation of the cleaning conditions. Keywords: Microfiltration; Karstic water; Drinking water treatment 1. Introduction Memcor® CMF, the world leading microfiltration process, has been well known for several years for its high efficiency in th ...

The fouling characteristics of ultrafiltration membranes used in drinking water were investigated when used alone and when used in an integrated biofilter-membrane system to treat a humic-acid laden solution. Membrane... without pretreatment). Chemical and microbiological analyses were performed on these strands together with different process streams along the treatment train. Microscopic observations performed on the sacrificial membrane strands revealed that most of the fouling material was organic in natur ...

Ultrafiltration as an alternative membrane technology to obtain safe drinking water from surface water: 10 years of experience on the scope of the AQUAPOT project
... water sources and sanitation worldwide, rural populations are disproportionately underserved. As a consequence, sustainable access to safe drinking water remains as an international target to be achieved before 2015, reflected in the Millennium Development Goals Declaration. Membrane’s... from UF-facilities installed on the scope of the AQUAPOT project were satisfactory and prove the suitability of UF technology in drinking water treatment from surface water. – Membranes showed a complete rejection of total coliforms and thermotolerants coliforms and guarantee continuous drinking ...

... air for membrane aeration can be increased. Focusing on water quality to be reused, major water quality indicators were always below corresponding drinking water limits as well as raw water concentrations. As a result, the reuse of UF treated SFBW should not lead to an influence of drinking water... During most water treatment processes, spent filter backwash water (SFBW) is generated. Reuse of SFBW is of concern because of the possible recycling of heavy metals ...

... requirements on water quality have stimulated ultrafiltration (UF) for water treatment. In this research, UF test apparatus was set up to produce drinking water from raw water of the Binxian Reservoir (China). The performance of UF membranes was investigated. There was a linear relationship betwee ...

Biofouling of ultra- and nanofiltration membranes for drinking water treatment characterized by fluorescence in situ hybridization (FISH)
This work showed that fluorescence in situ hybridization is a suitable method for the inves- tigation of biofouling in membrane processes for drinking water treatment. Similar attachment behaviour for the different subclasses of the proteobacteria was found as already observed in drinking water ...
