Wet Air Oxidation of Waste Water Sludge
Working with Wetox Ltd, a lab scale plant for the continuous oxidation of wastes from municipal water treatment and industrial processes has been developed at IRL using wet air oxidation (WAO). The WAO process can be used to significantly reduce the chemical oxygen demand (COD) of waste sludge and to recover components such as aluminium and phosphate. WAO requires high temperature (240 – 300 °C...
متن کاملBioremediation of reject water from anaerobically digested waste water sludge with macroalgae (Ulva lactuca, Chlorophyta).
Phosphorus and biologically active nitrogen are valuable nutrient resources. Bioremediation with macroalgae is a potential means for recovering nutrients from waste streams. In this study, reject water from anaerobically digested sewage sludge was successfully tested as nutrient source for cultivation of the green macroalgae Ulva lactuca. Maximal growth rates of 54.57±2.16% FW d(-1) were achiev...
متن کاملRadioactivity in Oily Sludge and Produced Waste Water from Oil: Environmental Concerns and Potential Remedial Measures
Produced water separated from oil is usually returned to the environment and could permeate through the water table. If such water is contaminated with radioactive substances, it could create a definite threat to the water supply, especially in arid regions where ground water and overhead streams are sources of potable water. Low-level radioactive contamination of oily sludge is equally hazardo...
متن کاملEffect of Temperature on Flow Properties of Digested Waste Water Sludge
The digested waste water sludge from the Zeinein station, North of Cairo was characterized for its physical and chemical properties. The flow properties of this sludge were followed at different temperatures, for different levels of solid content. The yield strength of the sludge was found to increase linearly with temperature. The apparent viscosity was related to absolute temperature by an eq...
متن کاملPerformance Evaluation of Hybrid Upflow Anaerobic Sludge Blanket Reactor in the Treatment of Dairy Waste Water
Dairy industries have shown tremendous growth in size and number in most countries of the world. These industries discharge wastewater which is characterized by high chemical oxygen demand, biological oxygen demand, nutrients, and organic and inorganic contents. Such wastewaters, if discharged without proper treatment, severely pollute receiving water bodies. For treatment of dairy waste water,...
