| Summary: | Wastewater collected from municipalities and communities must ultimately be returned to receiving waters or to the land or be reused. Water is a limited resource in the earth’s closed ecosystem. With the world population growing rapidly at very alarming rate, the demand for water is expected to increase in multiple progression and therefore, investigation of alternative methods for preparation of high quality water is necessary. The increasing pressures on water supply and the problems of municipal wastewater disposal can be solved by water reuse. Currently, the concept of deriving beneficial uses from treated municipal wastewater through water reclamation is receiving an increasing attention. Increased water shortages and waterway pollution are major problems posing risks to freshwater resources, with the highest risk from the industries. Wastewater effluent contaminated with heavy metals originating from numerous human and industrial activities is one of the major threats to the environment. In this keynote talk state of the art in water and wastewater treatments will be discussed. Recent progresses in our centre, bioenvironmental research centre here in Malaysia will also be highlighted. These include a new natural, environmentally friendly, safe, and sustainable phytodisinfectant from Moringa oleifera seed for water and wastewater treatment, Electrocoagulation (EC) which is a simple, environmentally friendly and cost effective process, when integrated with membrane filtration, very attractive for developing a sustainable water reclamation system. The other approach is the reclamation of biotreated palm oil mill effluent (BPOME), applying a developed hybrid adsorption-membrane process to produce boiler-feed water for low-pressure operating industrial boilers. Also the removal of heavy metals from industrial wastewater effluent by adsorptive membrane with the dual function of adsorption and filtration process using nanomaterial of graphene oxide (GO). Modeling of electroosmotic dewatering (EOD) of various materials including sludge. Finally the application of artificial intelligence (AI) technology in water and wastewater treatments for performance analysis and prediction will be indicated as tools necessary to the future chemical engineers. |
