Centralized System

The era is now facing water scarcity and the available water is being depleted at a faster rate to meet the needs of the growing population. At this juncture, it is essential to use the reduce-reuse-recycle strategy. Reducing excessive usage of water for essential needs and reusing the recycled water for non-consumptive purposes can be a great step in the conservation of water. The waste water from various sources can be collected and treated using an STP. In most of the cases, water treatment requires a centralized system of control and operation. The STP should be designed by considering the inflow characteristics, objective of the water treatment and availability of resources. There are various operational and managerial constraints while designing an STP. In case of overloaded condition of available STP, either some modification has to be done to prevent the decrease in efficiency of the obtained output or a new plant has to be constructed. In this case study, we have analyzed three different approaches to solve the issue of an overloaded STP. The results based on various criteria including cost of construction and maintenance have been discussed.

The Junagadh Agricultural University campus is located in Junagadh, which lies in western Gujarat. The human population on the campus is multiplied distinctively due to the establishment of new schools and hostels.The university campus had a population of 1418 in the year 2013 when the supply of water was 152 lit/day per person and the sewage generation was 0.0084 m3/s (725.76 m3/day).Hence, a sewage treatment plant (STP) with suitable capacity is needed to deal with the elevated sewage. The recycled water can be utilized for agricultural purposes. This paper discusses about the design of STP and its major components such as skimming, grit chamber, and screening chamber, active sludge, sedimentation tank and secondary clarifier in the end sludge drying beds. The proposed design is suitable for 0.0672 m3/s sewage and would help to provide58 MLD process capacity. In the end, treated water will have been used for irrigation purpose in the research field of a university.

Reclaimed water can effectively alleviate the water crisis which is the second water source of city. The functional relations in cost price, demand and transportation of the reclaimed water using are determined by the method of cost-plus which is based on the premise that the funds of reclaimed water network construction should be recovered. The users are divided into different groups according to the distance between the user and the water recycling. According to the demand diversity in different users, a complex tiered pricing model is established which is relevant of water requirement and the distance of conveyance. Finally, taking the Second Sewage Treatment Plant in Xi'an as an example, the water price of the user - the western suburbs Power Plant of Xi'an is calculated using this model. The result is consistent with the actual situation, which can verify the accuracy and usefulness of this article pricing model. All of these have provided a theoretical basis for the development of the market price of recycled water.

The combining of chemically assisted clarification with a proprietary physical separation technology has led to a high rate process for clarifying flocculated sewage and other waste streams. This hybrid physico-chemical system, known as the CDS Fine Solids Separation (FSS) System, was developed over a two year period within a sewage treatment plant environment. This paper summarises the results of a recent field trial of the system with a Victorian water authority which experiences heavy loading of sewers in a coastal town during holiday periods. The trial sought to evaluate the FSS as a tool for smoothing the load on the 11 km long sewer to the sewage treatment plant (STP). The FSS system could possibly enable the costly augmentation of the sewer to be deferred, particularly as the capacity of the existing sewer pipe is satisfactory for most of the year. Water quality parameters were determined for a range of flowrates and operational conditions over a two month period. Large reductions were achieved in TSS, TP, FC, turbidity and BOD5, with only minimal reductions in NH3 and TON. These results showed that the FSS could meet the authority's objectives for load levelling and would provide a 20-25% increase in effective sewer capacity. The data are also discussed in terms of possible use of the effluent from the FSS for water reuse applications.

A study was conducted on the reuse of the water in a system composed of a sewage treatment plant (STP) using prolonged aeration with activated sludge and a compact water treatment plant (CWTP) in a metallurgic industry. The processes for obtaining the water for reuse were microbiological and physicochemical. The domestic sewage was then pumped to the STP, where biological flocks were formed and clarified water was obtained. The efficiency of the microbiological process in the STP was evaluated for removal of biochemical oxygen demand (BOD), chemical oxygen demand (COD) and sedimentary solids (SS). The efficiency of physicochemical processes for clarifying the water and disinfection was evaluated through analysis of pH, turbidity, color, aerobic heterotrophic bacterial count, free chlorine, hardness, alkalinity, chlorides, sulfates and dissolved total solids (DTS). In the reuse of the water, acute toxicity for the microcrustaceans Daphnia similis was also evaluated.

Land area in the City State of Singapore is highly urbanized. Although 48% of the total land area of 620 square kilometres is reserved for water catchment and parks, water collected is insufficient to meet its needs. It derives its water mainly from Johor, Malaysia. To conserve water, reuse and recycling of wastewaters is encouraged in both the residential and industrial sectors. The Jurong Industrial Water Work was designed to reclaim treated sewage from the Ulu Pandan Sewage Treatment Plant. It has a capacity of 45,000 cubic metres per day. Pilot scheme to use this water for toilet flushing in housing estate was tried out. The scheme although highly successful is being suspended. The demand for reclaimed water from sewage for industrial water, however, increases steadily. This paper summarises the experience gained on reclaiming sewage for industrial uses.

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.
