Heavy Metal Removal And Desalination Through Development Of Nanfiltration And Ultrafiltration Membranes

Abstract

The demand for domestic and industrial water is expanding internationally as a result of population increase as well as fast economic development. Wastewater effluents from these and other activities affect the environment and are thus subject to stricter control. Research and development of water treatment technologies focuses on the efficiency of pollution removal and cleaning costs. Membrane distillation (MD) is a development of technology that is thermally powered and that achieves exceptionally good environmental performance with significant levels of renewable energy. Heating networks, especially biomass-powered, are a suitable supplier of heat for MD systems. This paper provides a technological evaluation of District Heating MD in chosen industrial applications for water treatment. The research includes examination of MD separation and the associated costs of several scenarios for the integration of district heat. newlineDesalination was increasingly seen as an opportunity and at times as a need in many parts of the globe to overcome water scarcity throughout the last several decades. In large-scale manufacturing for home and industrial uses today, numerous thermal and physical splitting processes are well established. Membrane distillation is a new thermal-driven method which, because of its potential reduced energy consumption and simplicity, may be utilized efficiently for water desalination or treatment in industrial applications. The main goal of this thesis is to help to develop the technological knowledge of membrane distillation as a novel technology for industrial as well as potable water treatment as a point of departure for future advancement. The thesis consists of experimental and numerical research which emphasizes certain characteristics and essential features of the use of technology. In the sphere of industrial application, an experimental and a count evaluation was conducted for the use of the technology at thermal cogeneration facilities, including the demineralization of water boiler feed wate
