Membrane Chemical Reactors: an innovative solution for the treatment of difficult fluid wastes
In this article we explain how membrane chemical reactor (MC-R) technology, recently developed by UK based Water Innovate (www.waterinnovate.co.uk), can treat a variety of recalcitrant fluid wastes in the industrial sector and in water reuse and municipal applications. MC-R significantly reduces the hard chemical oxygen demand (COD) content in the waste, which normally remains untreated by conventional biological treatment systems. The process utilizes the chemical, titanium dioxide (TiO2), as a photocatalyst within a closed-loop UV system, the chemical being initially mixed with the waste prior to UV treatment, and then selectively separated using advanced membrane technology. The chemical is not consumed but constantly recirculated and reused in the process.
