Membrane separation as a pre-treatment process for oily saline water

Zwitterion Embedded Thin Film Composite Membrane for Oily Wastewater Treatment

The recent development in oil and gas industry increases the production and consumption of oil. The enormous amount of oily wastewater produced is urged to be treated to prevent humanity and environment from being threatened. Membrane technology is an appealing alternative for oily wastewater treatment due to its design simplicity, energy efficiency and environmentally benign approach. In this ...

Progress of Membrane Engineering for Water Treatment

Together with the supply of energy and the environmental protection, fresh water is one of the three keys elements for the sustainable development of every society. Where the availability of water cannot be carried out by using conventional sources, unavoidable appears the resort of the major water source: the sea. Today, RO is one the most used membrane processes for the production of fresh wa...

Feasibility of electrochemical oxidation process for treatment of saline wastewater

Background: High concentration of salt makes biological treatment impossible due to bacterial plasmolysis. The present research studies the process of electrochemical oxidation efficiency and optimal levels as important factors affecting pH, salt concentration, reaction time and applied voltage. Methods: The sample included graphite electrodes with specifications of 2.5 cm diameter and 15 cm he...

Chemical Cleaning of Utafiltration Membrane after Treatment of Oily Wastewater

Preparation and Characterization of Microfiltration Ceramic Membrane for Oily Waste Water Treatment

This work highlights the preparation of ceramic membranes from a low-cost naturally occurring clay material viz. red mud. Additives like sodium carbonate, sodium metasilicate and boric acid was added in standard stoichiometric ratio with the processed clay material, imparting characteristic properties. Paste casting method was followed for fabricating circular disc shaped membranes with 50 mm× ...
