Electrodialysis Electroflotation

Electrolytic formation of finely dispersed bubbles (usually H2 and O2, from water electrolysis) can remove suspended particles from a liquid by floating them to the top. This solid matter can then be skimmed off from the top and subsequently treated. Much like electrodialysis, electroflotation is a process that concentrates the waste, which eventually needs to be treated and/or reused. It was estimated in 1980 that 20 electroflotation plants existed in the UK for treating industrial effluent [139]. Little to no information is available on the use of electroflotation for the decontamination of waste effluents in the USA. 

With regard to traditional water treatment technologies and their markets, new solutions should be found in order to settle current and future problems, as well as to improve the economical and ecological situations of several leading-edge processes. Electrochemical processes, such as electrodialysis, electrowinning, electrodeionization, electroflotation, electroflocculation and others, appear to provide solutions in certain ways to several problems.
