Abstract:

Due to urban overcrowding, the population density of residential areas and water use per unit are increasing. Therefore, it is necessary to study the flow of water supplied to cities and to improve the healthy circulation of urban water. This study used Modelica, a non-causal analytical program. Using Open Modelica, the researchers constructed a model linking water distribution and sewerage, as the basis of a balanced urban water model. Using the programmer's toolkit provided by EPA-NET and EPA-SWMM, which are commonly used to simulate the existing water supply and sewage pipe networks, Open M

Abstract:

The flow-rate restriction for storm sewage network is substantiated. Possible causes of flooding of territories by storm water in the case of emergency and methods of storm waters management are considered. The article is devoted to an increase in throughput of storm sewage networks with the help of in-line storm water detention tank installed at the beginning of storm sewage network and dragreducing polymers (DRP). It is proposed to introduce DRPs in the form of solution directly into the sewage network through a storm-water inlet or through a sewer manhole. The introduction is conducted from

This paper describes the sectorisation of a water network, as operated by the water and sewage utility (PWiK Gliwice, Poland) with electromagnetic water-meters (battery powered). This solution allows supply of District Metered Areas (DMA) by a few points without ‘dead-end’ pipework and shows that the main problems of the Utility are small, hidden leaks. Additionally the paper describes a water balance for the town of Pyskowice (part of the Gliwice water network) where all water meters are read by radio (automatic meter reading – AMR).

Abstract:

Chemicals such as magnesium hydroxide (Mg(OH)2) and iron salts are widely used to control sulfide-induced corrosion in sewer networks composed of interconnected sewer pipe lines and pumping stations. Chemical dosing control is usually non-automatic and based on experience, thus often resulting in sewage reaching the discharge point receiving inadequate or even no chemical dosing. Moreover, intermittent operation of pumping stations makes traditional control theory inadequate. A hybrid automata-based (HA-based) control method is proposed in this paper to coordinate sewage pumping station operat

Abstract:

Through increasing central development and through the decrease of specific wastewater production, wastewater systems are more and more prone to odour and corrosion problems. Hydrogen sulphide is produced, particularly in anaerobic flow stretches, which will then escape at turbulent places because of change in the flow direction and create odour harassment. Of particular importance in this respect are the transferring shafts after rising mains. The empirical approaches used for the estimation of the assumed sulphide concentrations yield considerable differences in the calculation and must ther

But due to lack of quality, inefficient water supply designs, intermixing of sewage water and unlined sewage water system, quality of water is deteriorated specially in recent decades and affecting a number of people. In present study, it was inevitable to design a water supply system for selected area to provide safe water supply design for a small community. For this purpose, a study area was selected named as chak.

Urban sewage recycling is one of the effective ways to improve ecological environment and to alleviate water supply and demand contradiction in urban areas. This paper analyzes the utilization condition and main constraints of recycling water in China, and believes that too many quality standards for recycling water lead to complex pipe network, and another main factor restraining sewage reclamation is the shortage of buffer storage link of recycling water. The author suggests incorporating the types and standards of recycling water to simplify pipe network, decentralize the reuse and use land

This paper presents a practical application of sewage network management strategy using radar data to control a detention-settling basin. This practical application, used in operational mode since January 2000, is based on three main notions. Firstly, the use of radar data without rainfall estimation. Secondly, the definition of some gradual risk levels for the sewage network by a detailed modelling of the sewage system functioning. Thirdly the definition of relations between risk levels for the sewage network and types of rain events defined from radar data. The operational application produc

Abstract:

The non-potable reuse of treated sewage in urban areas provides significant conservation of potable supplies beyond that available through water use efficiency. Effluent reuse is also an inevitable requirement in novel decentralised wastewater systems. At present, urban water reuse, where pursued, usually involves large-scale schemes based on new or existing centralised sewage treatment plants. This is despite the diseconomy of scale inherent in pipe networks that balances economies of scale in sewage treatment and negates any cost advantage for wastewater systems with more than around 1,000 c

Sewage pumping station is pumping station import at the sewage treatment plant. Its role is to collect the wastewater from the sewage pipe network to subsequent wastewater treatment process facilities. The water level is usually low in sewage collection pipe network. And many wastewater treatment facilities is based on elevation settings. So it is necessary to use lift pump to improve lift of the collected sewage, using high gravity sewage errands subsequent process in order to reduce energy consumption. The traditional way of pumping generally has the shortcomings: the waste of power resource

The sewage system is an important component of urban infrastructure. Most of the cities adopted efficient sewage systems to maintain the cleanliness of the cities. If the sewage maintenance is not proper, infectious disease may spread. Current sewage monitoring system is not efficient, as it is difficult to find out the poisonous gas level of sewage water. In the existing system, water level and temperature sensors are used to detect the overflow and the inside temperature of the sewage plant. An “IoT BASED SEWAGE GAS MONITORING SYSTEM WITH OVERFLOW DETECTION” is proposed to overcome the above

In drainage systems, it is often necessary to raise polluted rain and melt water to a low height. For example, pumping wastewater from one gravity collector to another, raising wastewater by several meters in order to reduce the deepening of the collecting sewer collector and, as a result, reduce capital costs for its construction. In such places, it may be more economically feasible to reduce such deepening. The novelty of the study is that the development of a drain can be fulfilled only if the filling of the throughput of the collectors is sufficiently ensured. The study shows that the poss

Abstract:

Abstract Sewer pipe networks are expected to operate with minimal or no interruptions. The complex nature of randomly occurring failures in sewer networks arising from blockages significantly adds to the cost of operation and maintenance. Blockages are significant due to sewage backup or basements flooding, resulting from their occurrence. Therefore, continuous performance assessment of sewer pipe networks is necessary to ensure required levels of service at an acceptable cost. This study provides insight into the performance of the sewer pipe networks by assessing the proneness of the network
