Sewage Waste

Sewage treatment is the process of removing contaminants from wastewater and household sewage, runoff effluents from domestic, commercial and institutional units. Various waste water treatment technologies have been compared for the Kullu, Manali area where there are about 50 Sewage Treatment Plan (STPs) installed and operated by various hotels, industries and 7 common STPs operated by the Irrigation and Public Health (IPH) Department for treatment of the sewage waste generated from the household and hotels in the three Municipal areas. The sewage load to the treatment plant installed by individual hotels is not available at a constant rate from the hotel industries. This variation in quantity and quality of the sewage generation during the tourist and non- tourist season disturb the whole mechanism based upon the biological methods. Thus there is a need to test a new technology to overcome these difficulties and which is easy to handle and operate and economical to run. Detailed study in association with Himachal Pradesh IPH Department in Manali Campus on new technology called the “Electro- Coagulation Technique” for treatment of the sewage waste was conducted by installing a demonstration study plant with a capacity of 60 Kilo- litre capacity per day ( 60 KLD). It has been concluded that this technology coagulates the suspended solids and settles into sludge, oxidizes organics and reduces soluble COD, and destroys pathogens

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.

Changes of microbial indices of water quality in the Vistula and Brda rivers as a result of sewage treatment plant operationThis paper reports the results of studies of microbiological changes in the water quality of the Vistula and Brda rivers after the opening of sewage treatment plants in Bydgoszcz. The study involved determining the microbiological parameters of water quality. Based on the results obtained, it was found that the quality of the water in both rivers had improved decidedly after the opening of the plants, although an increased number of individual groups of microorganisms was found at the treated sewage outlet from one of the plants.
