An extensive research programme has been carried out on advanced treatment of secondary effluents discharged by centralized activated sludge treatment plants fed on mixed textile/domestic effluents in order to produce a final effluent suitable for reuse in the textile factories. Activated carbon adsorption or membrane filtration (ranging from microfiltration to reverse osmosis) have been investigated at pilot plant scale in order to determine the most economical and performing advanced treatment. The increase in concentration of refractory pollutants and of salts discharged in the final effluents because of water recycling within the textile processes have been evaluated by relevant mass balances. A techno-economical analysis on the proposed treatment is also presented.

Water Treatment Plants

The musty-earthy taste and odour caused by the presence of geosmin and other compounds in tap water are major causes of consumer complaints. Although ozonation and granular activated carbon (GAC) adsorption have been practiced in water-treatment plants to remove these compounds effectively, two major problems associated with the application of these processes – formation of stringently regulated bromate ions by ozonation and unhygienic invertebrate colonisation of GAC filters – are still to be resolved. This research advanced the process of adsorption by powdered activated carbon (PAC) by reducing its particle size to the submicrometre range for microfiltration pretreatment. Adsorption pretreatment by using this super (S)-PAC removed the geosmin with vastly greater efficiency than by normal PAC. Removal was attained in a much shorter contact time and at a much lower dosage. The S-PAC was also beneficial in attenuating the transmembrane pressure rises that occurred between both physical backwashings and chemical cleanings.

High Concentrations

Toxic and difficult to biodegrade pharmaceutical wastewater is complex in composition with high concentrations of organic debris and microorganisms. There may still exit quantities of suspended particles and dissolved organic materials even after further treatment. Advanced treatment is required to improve the quality of pharmaceutical wastewater discharge. In this study, the pharmaceutical technology categorization has been established, and the features of pharmaceutical wastewater effluent quality have been summarized. On the other hand, The methods of advanced treatment of pharmaceutical wastewater have been incorporate, including coagulation and sedimentation, flotation, activated carbon adsorption, membrane separation, advanced oxidation processes, membrane separation, and biological treatment. In the meanwhile, each process's features were specified.

Filtration Technology

Kitchen Vehicle is an indispensable equipment to guarantee the food in battlefield, which played an important role in series of activities include military exercise, flood-fighting rescue and earthquake relief. Water is a necessity in processing staple and non-staple food in field operations, so there is an urgent need to have one safety water supply device with smaller volume and lighter weight to meet the demands of field kitchen work, therefore, a small vehicular water purifier based on the membrane filtration technology plus activated carbon adsorption and ultraviolet light disinfection technology is developed.
