The nutrient removal efficiency of Chlorella vulgaris cultivated in domestic wastewater was investigated, along with the potential to use membrane filtration as a pre-treatment tool during the wastewater treatment process. Chlorella vulgaris was batch cultivated for 12 days in a bubble column system with two different wastewater treatments. Maximum uptake of 94.18% ammonium (NH₄-N) and 97.69% o...

In big cities, the cost of treating wastewater is increasing with more stringent environmental requirements. Ionizing radiation technology for treating municipal wastewater may be an alternative to reduce treatment costs. In this paper, laboratory tests were carried out using different doses of radiation to treat wastewater samples collected from the AL-Rustamia wastewater treatment plant in Ba...

Providing reliable and affordable wastewater treatment in rural areas is a challenge in many parts of the world, particularly in developing countries. The problems and limitations of the centralized approaches for wastewater treatment are progressively surfacing. Centralized wastewater collection and treatment systems are costly to build and operate, especially in areas with low population dens...

the growing scarcity of fresh water is driving the implementation of wastewater treatment and water reuse on an increasingly large scale. various methods have been developed and used for water reuse from wastewater; however, the membrane distillation (md) process, as a promising separation technology, has recently gained more attention. the md process is a non-isothermal membrane-based separati...

Wastewater treatment for removal of organic matter, inorganic matter and heavy metals is becoming increasingly important area of research. The disposal of wastewater to sea and other reservoirs can cause serious environmental problems. Wastewater from petroleum and refineries contains organic matter in various forms. Biodegradable and nonbiodegradable pollutants call for different biological an...

Focus The Wastewater Management Program includes wastewater collection and conveyance, wastewater treatment, and planning and monitoring program a...

Li Si, Kong Ruixue, Sun Lin, Li Sifan, Yang Shuangchun* (Liaoning Shihua University. Fushun, Liaoning, China. 113001) Abstract—Industrial wastewater is a kind of wastewater that generate in the industrial production process. The wastewater from refining and coal carbonization contains high concentration of phenols pollutants. In this paper, study on phenol treatment methods in industrial wastew...

Packed bed reactor finds wide application in wastewater treatments. Packed bed reactors can be employed for aerobic and anaerobic biological treatment of wastewater. They can also be used for physico-chemical treatments such as activated carbon adsorption of various pollutants from wastewater. Packed beds with up flow and down flow mechanisms are widely used for wastewater treatment. Use of flu...
