Abstract:

AbstractThe study provides a comparative analysis of the quality of sewage discharged from selected sewerage systems. The analyzed data were collected from 10 agglomeration sewerage systems discharging sewage into collective wastewater treatment plants (WTP). The investigated pollution indicators included BOD5, CODCr, total suspended solids and biogenic indicators such as total nitrogen and total phosphorus. These results were compared with the outcomes reported in commonly available research papers on sewage disposal. Considering the concentration of individual pollution indicators, more deta

Abstract:

As a result of the spread of sewerage systems, the management of growing quantities of sewage sludge is becoming an urgent need. As the method of sludge management, thermal processes have mostly been applied to the treatment and disposal of sewage sludge in Japan, because of the difficulty of finding final disposal sites. This paper describes the progress of thermal processing technologies, especially focusing on drying-incineration process systems and melting-slag recycling process systems.

Abstract:

Land disposal of human wastes is a comprehensive issue, where a series of aspects have to be considered. Few, if any, alternatives exist to this technology. No doubt future emphasis will be on sewage farming, which should result in the cultivation of new arid land. This paper addresses the prolonged effect of land disposal of human wastes on soil properties, as well as on the dissemination of enteric pathogens. In order to assess this impact, soil samples were collected from Gabal el Asfar sewage farm in Cairo to represent sandy soils irrigated solely, by surface flooding, with decanted sewage

Abstract:

with the continuous acceleration of urban and town construction, the output of urban and town sewage is also increasing. To a great extent, this promotes the technological development and capacity expansion of urban and town sewage treatment plants. In the process of sewage treatment, a lot of sludge is inevitable. However, many urban and town sewage treatment plants pay more attention to the treatment of sewage and ignore the treatment of sludge. In this way, the sludge without proper treatment can be disposed at will. In the long run, this will not only affect the surrounding environment, bu

Abstract:

Control of the ramified head-and-gravity wastewater disposal system of Moscow is considered with respect to the possibility of redistributing flows of sewage between structural components through underground hydraulic connections (sewers). It is supposed that the sewerage pumping stations of a network are characterized by various consumptions of electric power for pumping a unit volume of sewage (specific consumption). Analysis is limited by the subsystem of transportation of the sewage (sewerage network). Controlling the network is reduced to the purposeful redistribution of the sewage flows

Abstract:

Sewerage systems and sewage treatment plants are often planned, designed and operated as totally separate entities. As a result, sewage treatment efficiency is subject to considerable variability, depending both on general hydrologic conditions in the urban watershed (wet versus dry periods), and on specific “instantaneous” operating conditions. It has been postulated that the integration of design and operation in urban drainage and wastewater treatment could allow minimization of the harmful effects of discharges from treatment plants, combined sewer overflows and surface runoff.

Abstract:

The Norwegian public health and environmental authorities have launched a regulation for sewage sludge handling and disposal aiming at increasing the amount of sludge to be utilised on land areas. The strategy for achieving this is to secure that only high quality sludge is being offered to agriculture and green areas; the two disposal routes acceptable for land application of sludge in Norway. Most sewage treatment plants have experienced a considerable reduction in sludge heavy metals content during the last 15-20 years and the major reason for this is believed to be the continuous control o

The disposal of sewage into aquatic systems is attracting increasing regulation at the European Community level. Initially, pollution control strategies focussed on the protection of rivers and inland waters from excessive oxygen demand loading. This has led to an increasing use of marine waters for the disposal of sewage effluents and sludges. The bacteriological hazards associated with these practices are now well understood and have led in turn to restrictions on such disposal activities. This problem is illustrated with data from Venice Lagoon showing extreme bacterial contamination. A les

Abstract:

A reliable, unobtrusive wastewater collection, treatment and disposal system in tourist areas is a must. In most countries where tourism has rapidly grown, public utilities have not managed to provide sewerage and sewage treatment facilities. As a result of this there are a great number of small sewage treatment plants each serving one hotel or a group of hotels in one area. The next step seems to be to join more and more hotels to one bigger treatment plant - mostly operated by a public utility. This paper discusses the pros and cons of a centralized vs. decentralized treatment system taking

Abstract:

Currently there is great concern about the lack of drinking water in the world, today Brazil has already suffered the consequences by waste and improper disposal of waste, suffering already with several forced rationing. Improper disposal of sewage is the main cause of soil pollution, groundwater, surface water sources and water courses in Santa Catarina. Among the existing municipalities in the state, only 8% are met with services by the sewage system, while the national average is 19%. More efficient existing sewage treatment systems are extremely large, with this in order to solve the probl

Abstract:

Abstract Municipal wastewater treatment results in the production of large quantities of sewage sludge, which requires proper environmentally accepted management before final disposal. Sewage sludge is a by-product of current wastewater treatment technologies. Sewage sludge disposal depends on the sludge treatment methods used in the wastewater treatment plant (anaerobic or aerobic digestion, drying, etc.). Taking into consideration presented given this information, a study concerning the effects of wastewater treatment processes and sewage sludge drying method on the sewage sludge gasificatio

The paper studied enhanced treatment of sewage from discharging points of rivers by bio-film process dosing with enzyme and investigated the promotion effect of enzyme on treatment of sewage by bio-film process. The removal of phenol in sewage was also researched. The experiments results indicated that during the ebb tide, the remove rate of phenol was stable (33%) on the eighth day in the dosing pools and it was stable (31.6%) on the eighth day in the contrast pool. During the rising tide, the remove rate of phenol was stable (30%) on the eighth day in the dosing pools and it was stable (27.2

Abstract:

Severn Trent Water screens approximately 1.9 million cubic metres of sewage every day, producing 46000 m3 of screenings annually. Although the company's sludge incinerators are able to burn small quantities of screenings most of the material has to be landfilled. Over the last few years the company has investigated the areas relating to the development of an environmentally sound disposal strategy at minimum cost. These areas have included the volume and “quality” of screenings produced, the costs of collection, treatment and disposal and the variation of screenings production rates under high

Palm liquid sewage is organic waste that contains complex compounds such as water, oil, and organic solids. The organic content of palm liquid sewages is an indication of the abundance of microorganisms. This study aims to obtain anoxygenic photosynthetic bacteria (BFA) that produce carotenoid pigments from palm liquid sewages. Therefore, We isolated and screened of BFA from three palm liquid sewage disposal sites in Jambi Province. This research was conducted by an experimental method using a modified mineral medium. BFA isolates that growth and produced carotenoid pigments are visible becaus

The development of public sewerage systems in Slovakia is significantly behind in the state of supply of drinking water. The number of inhabitants connected to the public sewerage system in Slovakia is considerably lagging behind in the state of the population supplied with drinking water, by about 28.4% less in the number of connected inhabitants. Designing sewerage in urbanized areas improves the quality of the environment and the quality of life of townspeople and municipalities.

Abstract:

Sewage sludge is an inevitable product of all conventional sewage treatment processes. Disposal of sludge in an economic and environmentally-acceptable manner is becoming generally more difficult. Sludge quantities are rising and disposal options decreasing. Disposal will increasingly require positive and careful management. There are four basic destinations for sludge - agriculture, other types of land, the sea or minor outlets. Treatment methods are available for the production of nine basic types of end-product to suit particular disposal requirements. The new EC Directive will regulate slu
