The main energy consumers in sewer networks are the sewage pumps. Therefore, to minimize the energy consumption, it is essential that these pumps operate under satisfactory conditions. Knowledge about the efficiency of the pumps and their operating conditions can help the pump station management to operate the system optimal. In the search for innovative solutions that can help the sewer management with this information, we propose a method that provides information on the pump flows, the inflow to a sewage pit, and an online estimate of the efficiency of the pump. All these information are obtained without a flow sensor. We argued that the calculated flow values can be used by the sewer management to optimize the operation on the sewer pumps, and the efficiency estimate can be used for optimal scheduling of maintain procedures. The flow and the efficiency estimations are exemplified on a pumping station of the sewer network in Herning, Denmark.

Pump Stations

In many places lifting systems represent central components of wastewater systems. Pumping stations with a circular wet-pit design are characterized by their relatively small footprint for a given sump volume as well as their relatively simple construction technique [1]. This kind of pumping stations is equipped with submersible pumps. These are located in this case directly in the wastewater collection pit. The waste water passes through the pump station untreated and loaded with all kind of solids. Thus, the role of the pump sump is to provide an optimal operating environment for the pumps in addition to the transportation of sewage solids. Understanding the effects of design criteria on pumping station performance is important to fulfil the wastewater transportation as maintenance-free and energy efficient as possible. The design of the pit may affect the overall performance of the station in terms of poor flow conditions inside the pit, non-uniform und disturbed inflow at the pump inlet, as well as air entrainment to the pump. The scope of this paper is to evaluate the impact of various design criteria and the operating conditions on the performance of pump stations concerning the air entrainment to the pump as well as the sedimentation inside the pit. This is done to provide documentation and recommendations of the design and operating of the station. The investigated criteria are: the inflow direction, and the operating submergence. In this context experiments were conducted on a physical model of duplex circular wet pit wastewater pumping station. Furthermore the same experiments were reproduced by numerical simulations. The physical model made of acrylic allowed to visualize the flow patterns inside the sump at various operating conditions. This model is equipped with five different inflow directions, two of them are tangential to the pit and the remaining three are radial in various positions relative to the pumps centerline. Particles were used to enable the investigation of the flow patterns inside the pit to determine the zones of high sedimentation risk. The air entrainment was evaluated on the model test rig by measuring the depth, the width and the length of the aerated region caused by the plunging water jet and by observing the air bubbles entering the pumps. The starting sump geometry called baseline geometry is simply a flat floor. The tests were done at all the possible combinations of inflow directions, submergence, working pump and operating flow. The ability of the numerical simulation to give a reliable prediction of air entrainment was assessed to be used in the future as a tool in scale series to define the scale effect as well as to analyze the flow conditions inside the sump and to understand the air entrainment phenomenon. These simulations were conducted using the geometries of the test setup after generating the mesh with tetrahedral elements. The VOF multiphase model was applied to simulate the interaction of the liquid water phase and the gaseous air phase. On the basis of the results constructive suggestions are derived for the design of the pit, as well as the operating conditions of the pumping station. At the end recommendations for the design and operating conditions are provided.

The main goal of this study is evaluation of reconstruction options for water pumping stations, regarding various factors (equipment purchase cost, maintenance, energy consumption). The search for the most profitable solution was carried out using the life cycle cost methodology for the urban water supply system’s first lift pump station. An analysis of the operating modes of the pumping station was carried out using curves of pumps and system. It was found that the option with a higher purchase price has the best technological indicators, including energy consumption. The expediency of the complete replacement of pumping equipment is confirmed by an analysis of life cycle costs.

Since reducing energy consumption is a priority for an enterprise, economic effi ciency in general is directly related to the use of pumping equipment. The demand for electricity for pumping equipment will depend on various factors: the operating modes of pumping stations and installations, the equipment used measures to reduce the cost of electricity consumed, etc. The current practice indicates extremely inefficient operation of pumping equipment. Currently, a large number of pumping stations of water supply and sanitation systems operate in an uneconomical mode. Very often, this is due to incorrect selection of pumping equipment, outdated pumping equipment, the operation of pumps in non- calculation mode. In addition, pumping equipment has been installed in many industries since the establishment of production. Such equipment is morally and technically outdated. Now,technological progress allows us to use more efficient equipment and materials that allow us to reduce energy consumption. The article presents an analysis of the energy consumption of a pumping station of technical water supply on the example of JSC «Omsk Kauchuk», a variant of modernization is proposed in order to reduce the consumption of electricity by pumping equipment. The need to modernize the pumping station of technical water supply is associated with a significant service life and high –energy consumption of pumping equipment. Two pump brands were selected and a comparative analysis was carried out. Based on calculations of energy consumption and technological characteristics, the most profitable and optimal version of the D6300-80-2b pump was chosen, since the pump performance is greater and the power consumption is less than that of the JETEX DS600-750 pump, as well as reducing the wear rate of operating elements, improving the pump’s suction capacity

Abstract As part of a collaborative research project (OPTIMA) by Fraunhofer FOKUS, Engineering Company Prof. Dr. Sieker mbH, Department of Distributed and Operating Systems and Department of Fluid System Dynamics, TU Berlin, an „Intelligent Pumping Station” is being developed. In this research project, the operation of wastewater pumping stations is to be optimized by integrating precipitation forecasts and recording operating conditions on one hand, and by integrating historical data on use and operation on the other. The individual strategies for optimizing the operation of pumping stations and the possibilities of data integration will be systematically investigated. The focus of this paper is on the method for developing an optimized pump control. It examines how knowledge of predicted inflow can be used to achieve energy savings and a reduction in wastewater overflows. This method is based on the development of an algorithm in which detailed consideration of pump specifics and future pumping station inflow can be used to predict all possible suction head level curves for the considered period of time. Depending on the target criterion — minimum energy consumption per transported cubic meter or minimum overflow volume — the algorithm calculates the optimum path from all possible suction chamber level curves.

Water supply pumping stations are among the main energy-consuming elements in the water supply system. The energy optimization of a pumping station can significantly affect the energy consumption of a water utility. This article deals with the energy optimization of water pumping stations. The work assumes several variants of optimization of water supply pumping stations through changes in the water supply system, pressure changes in the pumping station, and modification of the number of pumps. After analyzing the network, conducting field tests, and creating a model of the water supply network, the network was calibrated in order to reproduce the existing water network as accurately as possible. Then, a variant analysis was performed, and the best optimization method for the pumping station was selected. In two variants, there was a decrease in electricity consumption; in three there, was an increase; in one, there was no change. By connecting the DMA zones and modifying the pressure in the pumping station, the energy consumption of the pumping stations was reduced. On this basis, it was found that it is possible to optimize the water pumping station by modifying the pumping station and work related to the network layout.

Melt Water

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 possibilities of expanding collectors can be achieved based on compensation for energy consumption. The study outlined the necessity of allocating the device of a high-pressure pumping station with the subsequent laying of a pressure sewage collector to a common collector, or to the main sewer network, which in turn supplies rain and melt water to the main collector. The practical significance of the study is the widespread introduction of intermediate pumps of low pressure in sewerage networks is constrained by the lack of a sufficient range of reliable and economical low pressure pumps for contaminated liquids.

For the reason that current pump performance parameters and its piping system do not match, a new plan was proposed in this study to improve the low efficiency and reduce the high-energy consumption of Zhenjiang water intake pump station. According to the measured data in the field and the design information of the pumping station system, the simulation model of the pumping station is established with the help of commercial software Flowmaster. Based on this model, the simulation of various operating conditions is carried out. Considering the running condition of the pump station in the past years, the design condition spectrum of the new pump station is finally formed. On the purposes of optimizing the scheduling and decreasing the reconstruction cost, the implementation plan of pump station reconstruction was determined. Under the guidance of the plan, the work of design, manufacturing, testing, installation and debugging of a new type of double suction pump are completed in combination with the actual situation. The results show that the cost of electricity can be saved by 35,000 dollars and the cost of reconstruction can be recovered in less than one year. This study realizes energy-saving in the pumping station operation.

As odour nuisance can affect the quality of life, the population is more and more demanding and in many cities sewers are a critical source of odours. Both factors can lead to increasing numbers of complaints due to the odour nuisance perceived by the residents, affecting also the public image of the sewer management companies. Odours associated with sewer networks are very heterogeneous, in as much as the different ‘types of odours’ encountered are sewer site specific. The state of the art indicates that there are three parameters that play an important role with the nuisance generated by an odour: hedonic odour tone, odour concentration and odour intensity. This paper presents the results of the study on odour nuisance carried out in different points of the sewer network, with the aim to assess the nuisance generated and identify which points of the sewer should be targeted to implement corrective actions. Considering the different parameters assessed, pumping stations have been identified as critical points of odour nuisance in the sewers, being recommended to implement an odour treatment system in order to guarantee the odour comfort of residents.
