To solve the shortage of available water source, the national government and local authorities have introduced the policy to make use of alternative water sources such as reuse of wastewater and utilization of rainwater in big buildings. This paper deals with the background, the details of the practice of wastewater reuse systems in buildings, and survey results on the performance of recycling systems installed in big buildings. The investigation suggests that most of reclamation plants perform very good in quality but not good in quantity. There has never been any serious claim from users nor any hygiene trouble in these several years. But the full capacity of plants was not usually utilized as designed. The very small demand at weekends and holidays creates operational problems of biological treatment plants and raises cost of reclaimed water. Individual building wastewater reuse is not efficient enough as expected to solve the shortage of water resources. However, it still remains to be a very important means to deal with urban problems. It will lessen excess loading on existing sanitary sewers and interceptors, and will reduce pollutants discharged from a sewage treatment plant.

Abstract:Phosphorus is a major substance that is needed especially for agricultural production or for the industry. At the same time it is an important component of wastewater. At present, the waste management priority is recycling and this requirement is also transferred to wastewater treatment plants. Substances in wastewater can be recovered and utilized. In Europe (in Germany and Austria already legally binding), access to phosphorus-containing sewage treatment is changing. This paper dealt with the issue of phosphorus on the sewage treatment plant in Nitra. There are several industrial areas in Nitra where record major producers in phosphorus production in sewage. The new wastewater treatment plant is built as a mechanicalbiological wastewater treatment plant with simultaneous nitrification and denitrification, sludge regeneration, an anaerobic zone for biological phosphorus removal at the beginning of the process and chemical phosphorus precipitation. The sludge management is anaerobic sludge stabilization with heating and mechanical dewatering of stabilized sludge and gas management. The aim of the work was to document the phosphorus balance in all parts of the wastewater treatment plant - from the inflow of raw water to the outflow of purified water and the production of excess sludge. Balancing quantities in the wastewater treatment plant treatment processes provide information where efficient phosphorus recovery could be possible. The mean daily value of P tot is approximately 122.3 kg/day of these two sources. The mean daily value of P tot is approximately 122.3 kg/day of these two sources. There are also two outflows - drainage of cleaned water to the recipient - the river Nitra - 9.9 kg Ptot/day and Ptot content in sewage sludge - about 120.3 kg Ptot/day - total 130.2 kg Ptot/day.
