INDUSTRIAL WASTE WATER TREATMENT AND OTHER ENVIROMENTAL PROBLEMS IN WUHAN Han, S.S., Wu, X., 2004. City profile Wuhan, Citites, Vol. 21, No. 4. 349-362. Clean water is an essential resource for people and their environments throughout the world. Those who provide effective solutions for wastewater treatment play a major role in returning clean, safe water back to its source. In fast pace of modern lifestyle, great advances have been made in the development of efficient technologies but challenges still remain. In this outlined some major challenges being faced by wastewater treatment plants. Energy consumption is one of the largest expenses and challenges in operating a wastewater treatment plant. Wastewater treatment is estimated to consume…show more content…
Furthermore, a major environmental challenge for wastewater treatment is the disposal of excess sludge produced during the process. Safe and long term solutions for the destination of sludge produced by wastewater treatment plants are a vital element of a sustainable functioning facility. The recycling of sludge, containing useful organic matter and nutrients in agriculture is considered as the best solution. In other hand, some more modern treatment technologies are even able to reduce the burden of sludge by lowering its production. Activated sludge treatment has many challenges that one of the biggest being the footprint it demands. Activated sludge plants are costly to construct and occupy substantial land areas. Primary and Secondary processes rely upon vast tracts of land for large and costly settling tanks and aeration basins. Due to high populations constantly increasing, municipal wastewater treatment plants need to expand their capabilities. Advanced technologies that use smaller process basins by increasing the amount of biomass per unit volume via the addition of media for biofilm attachment (such as IFAS and MABR) or increasing the biomass concentration (such as…show more content…
Adjustments to the change will have to take place. For this there is a need for further research and observation of the changes. Climate change, increasing drought frequency and intensity, and high demand of water are increasing scarcity in certain countries. High agricultural consumption, increased salinity and underdeveloped conservation technologies compound the pressures on the nation’s water supply. Ultimately, climate change is likely to have a negative impact on countries and make them increasingly difficult to meet urban and agricultural water needs. Among the challenges ahead, measures are already being taken for the mitigation of climate change with water supply and disposal. The recycling of wastewater can promote employment within irrigation systems. Treated wastewater and also surface runoffs can be deliberately percolated (groundwater replenishment) and then used again later. Flooding events can be mitigated through dykes or mobile flood protection systems. Emergency systems for droughts must be tested and prepared. Operating personnel must be trained in advanced for these tasks. Only then are the adjustments to climate change successful and the required emergency measures correctly targeted.Eventually, water scarcity is among the main problems facing many societies and the world nowadays. Water use has been growing at more than twice the rate of the
