ENHANCEMENT OF INDUSTRIAL WASTEWATER TREATMENT PRO-CESS USING NEW GENERATION FILTERS
Journal Title: Journal of Mechanical Engineering Research & Developments (JMERD) - Year 2018, Vol 41, Issue 2
Abstract
Natural water and wastewater is treated at public utilities and industrial facilities using filters of various designs that are filled with filtering materials containing electric-chemical sources of cur-rent. Main limitations of common filters are: iron case internal corrosion; high electrode resistivity; low current collection from 1m2 of electrode surface area; poor water treatment efficiency. En-hancement of industrial wastewater treatment process is aimed to create a new filter design that would allow to eliminate the above-listed limitations of filter designs currently applied. The pro-posed design of new generation filters includes: iron case filled with filter material, electropositive and electronegative electrodes placed vertically inside the filter case. Electropositive electrodes are made of carbon-containing electrode composition consisting of calcined coke fines, pyrrhotite tailings from mining and refining facilities and tall oil pit. The applied composition of electrode shell allows to decrease their resistivity and to increase their current collection, as well as to slow down the corrosion of iron filter case. Using new generation filters allows to improve the quality of treated water: for example, in case of using common filters iron residual concentration after treatment of wastewater makes 0,35 mg/l; using new generation filters reduces the iron residual concentration to 0,18 mg/l.
