Abstract:

Introduction. From the sanitary and epidemiologic point of view the economic and household sewage making more than 80% of the volume of all water disposal is of the greatest practical interest. The infectious agents getting to the sewerage do not perish independently. The problem of treatment facilities of the sewerage consists of prevention of possible distribution through water of intestinal and parasitic infections. Aim of the study. To investigate the overall efficiency of sewage treatment facilities in relation to pathogenic and sanitary indicator bacteria and pathogens of parasitic disea

Abstract:

In many Dutch sewerage systems the sewage is pumped from small villages through pipelines to larger cities. These pressurized pipelines often end up in the pump sump of another pumping-station or in another sewerage system which transports the sewage under atmospheric conditions to the waste water treatment installation. When the waste water in these pipelines stays stationary for a longer period often sulphurous compounds are formed. At the downstream end of the pipeline, where the sewerage system meets atmospheric, aerobic circumstances, the hydrogen sulphide can be converted into sulphuric

Abstract:

It is in the nature of sewering and sewage treatment to compound environmental problems in the processof moving sewage and in attempting to remove from sewage the pollutants it carries. Spreading sewage sludge on land is but the latest in the compounding of environmental damage from sewerage. This practice must be banned and there must be a federal reorientation of all technology dealing with human excreta and the waste materials from industry and society that now are carried away by sewers. The reorientation must center on biologically based on-site pollution prevention and resource recycling

Abstract:

The water-carried sewerage system has replaced the older, more basic technique of excreta disposal as the cities have grown. The infrastructure of any society's water supply and sewage system is crucial. The purpose of a sewer network is to move home or industrial waste water from a source location to a treatment facility or disposal site. The sewage system consists of a network of sewer lines that, at their nodal points, collect and discharge waste materials into a separate network of sewer lines. Since then, a lot of researchers have made contributions to this topic. As a result, an effort h

Abstract Informal housing, and operational and management deficiencies, influence sewerage system performance in Brazil. Inadequate sewage volumes in storm sewers lead to fecal contamination and affect recreational water environments. As overflow structures, dry-weather sewage intakes (DWSIs) are used to intercept and transfer sewage from storm- to sewage- sewers. For cities without public services, the DWSI strategy has been suggested as an option to enable easier and more rapid responses in terms of sewage pollution control. The strategy may also lead to gradual construction of a separate se

Abstract:

The mechanical-biological waste treatment plants (MBTP), which include the municipal waste biogas plants, have an important role in sustainable urban development. Some plants are equipped with a sewage pre-treatment plant, which is then directed to the sewerage system and the treatment plant. Others, on the other hand, have only a non-drainage tank. The parameters of technological sewage (TS) or processing technology could reduce sewage contamination rates. In addition to the quality of sewage from waste treatment plants, the emission of odours is also an important problem, as evidenced by the

Abstract:

A study on the optimization planning of water pollution control for Majiagou Stream in Harbin was carried out. Four water pollution control options were considered. The option regarded as most feasible, both technically and economically, involved the construction and operation of a wastewater treatment works with a capacity of 150,000 m3/day on the upper reach of the stream. The effluent would be discharged into the upper reach of Majiagou Stream and would be used as a water source for the stream, while an interceptor sewer was to be constructed on the lower reach of the stream to collect wast

Abstract:

The objective of the study was to find out to what extent water charges could be used in the developing world. This paper presents a cost recovery model primarily for water supply and discusses its implications for sewerage services. The model has four key elements: benefits and costs, predictability of consumer contributions, water tariffs, and fee collection and financial management. The study shows that water charges are a necessity in developing countries, as in the developed world, and consumers are more able and willing to pay than has been thought.

This study anticipates that further treated-sewage reuse in industrial sectors, commercial buildings and public parks, in addition to present in-plant and street cleaning purposes, would increase total water reuse to about 10%. New water reuse technologies using membrane bioreactor (MBR) and microfiltration (MF) as tertiary treatment were implemented to assess their potential for their application in the Bangkok Metropolitan area. The MBR was applied to the treatment of raw sewage in a central treatment pla

Abstract:

Quantitative information was obtained on the processes of sedimentation, mineralization and resuspension of organic matter in a combined sewerage system by means of statistical analysis of dry and wet weather data on sewage flows. The effects of temperature and length of intermittent dry weather periods on daily pollutant loads were also evaluated. For the sewerage system investigated it was found that in summer 5-26% of the BOD produced is mineralized in the system before reaching the sewage treatment plant. Due to sedimentation under dry weather conditions up to 12% of the daily organic load

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.

Industrial contributions constitute as much as 20% of the 700 000 m3 .d−1 of sewage discharged to the Saronikos gulf through the sewerage system which serves the Greater Athens area. The main industrial discharges originate from food, textile, pulp and paper, chemical, tanning and metal processing and electrical industries. In the majority of the cases the pretreatment is inadequate and the existing emission standards are violated. This results in increased concentrations of toxic metals in the sewage. The impact of these toxic discharges on the marine environment and the sewage treatment work

This type of compact, biofilm treatment became popular because of its inexpensive construction and energy-saving characteristics.
