Abstract :
Abstract Water scarcity is becoming a major problem in both developed and developing countries. Water resource research, as well as the recycling of wastewater treatment plants, might all contribute to making water resources more sustainable. The purpose of biological wastewater treatment is to progressively oxidize organic contaminants. Many pollutants, rather than being completely converted into carbon dioxide and water, remain stable for biodegradation or just undergo modest structural modifications.On the other hand, enhanced non-living purification processes, such as membrane filtration, UV decomposition, ozonation, and advanced oxidation processes, including cavitation, may be discarded. Cavitation technology has been able to overcome the drawbacks of many systems that require chemicals or high energy input in their processes, and it promises to alleviate the global water crisis by improving the efficiency of water and wastewater treatment. The function of hydrodynamic cavitation in each of the treatment processes is discussed in the next part, which investigates one of the most potential applications of hydrodynamic cavitation, namely wastewater and water treatment.
