Energy Balance Determination At Catchment Level

Document Type:Proposal

Subject Area:Engineering

Document 1

Using these aims, can help in the determination of the energy balance at a given level of catchment of the energy amount that is utilized in the consumption, disposal and supply of one cubic meter of the water as it goes along the water cycle of the urban. Supporting information has been drawn from a broad range of academic, water-industry, national government and EU literature, to enable a representative outline of water related energy consumption to be presented. Contrasting systems of reporting and governance at both the institutional and corporate levels, made finding common energy consumption values for each stage of the urban water cycle problematic. This was further compounded by geographic, climatic, topographical, hydrological, process and legislative differences that exist across the countries where existing data is available.

Nevertheless by drawing on a range of examples from across selected nations and examining a number of case studies, it will be possible to piece together the relationship between energy and water of the water cycle in the urban. The studies about energy saving should be focused in the water cycle in the urban will be also be determined. Furthermore, the modelling tool foundation with regards to operator system and policymaking will be also be used, hat will be used to approximate the losses and uses of the major energy within the water system of an urban. Objectives 1. To assess operational of data, thermal performance of energy and chemical of water cycle in the urban. To determine measurement of the energy balance, modelling and energy potential and heat flux in various water cycle within urban.

The needed energy for treatment, distribution and pumping within the urban cycle of water are variables that rely on the factors that include treatment methods, policies of nations of different countries and location characteristics. Table 1: Embedded energy approximation from various sources Sources Needed Energy Variables of Energy -kWh/acre ft* Groundwater Pumping Depth of Groundwater 170-750 Imported Surface water Pumping Distance of Flow 1800-3000 Local Surface water Pumping Distance of flow 34-450 Recycled water Pumping Distance of Flow 498 Brackish-water Pumping Concentration of Salt 403-1800 Seawater Pumping Power plant colocation, Energy recovery devices 4,550-5,550 UV disinfection Lamps lamp pressure dose, reactor hydraulics, flow 6. 4-30 Ozone disinfection Generator Feed gas system flow dose 6. 4-50 Micro ultra-filtration Pumping Pressure from feed 131-327 Reverse osmosis Pumping Pressure from feed 160-1,570 Bioreactor Membrane Pumping and aeration Air-transfer efficiency and pore size 980-2,442 The linear relationship occurs in the energy intensity depth and value in the pumping as anticipated in the groundwater.

The energy intensity ranges from 170-750 kWh/mil gal which has mainly reported for the water that is portable. 11 m2 32. 012 Standard Pavement 1. 20 m2 164. 012 Structural Detention Facilities 1. 00 m3 849. Waste water strategies to reduce energy targets to decrease inflow and infiltration within the center of collection of the system so that to collect energy potential to be able to breakdown biosolids matter. For an example, use of the combined power and heat and use of the hydraulic generation of energy have been studied and showed that it achieved cos saving and optimization of energy. The energy minimization key concept in the water section is through the operation and design of well cycle of water in the urban. Consideration of the drainage construction and the infrastructure is needed because of energy consumption during the process and hence the project proposal focuses on the balance of energy in the maintenance and operation of the urban cycle of water and it can be a major sustainability and beneficial.

METHODOLOGY Introduction Various methods are employed in this study so as to get outcome that is quality. The tools output is targeted at makers of the policy and operators of the system, financial decision and political Methods This proposal project will apply various methods of calculation for consumption of energy in various part of cycle of water in urban. The energy intensity for pumping is calculated by; pumping energy intensity is calculated by In determination of heat flux through energy transfer, some of the calculation will be also be used. Heat flux denoted by B is measured by energy per unit of time. All the calculation methods will be used in conjunction with the data that exist for energy transfer, consumption of energy at various section of the urban cycle of water that include maintenance, treatment and pumping.

Carbon Reduction: Carbon Capture and Sequestration (CCS) The carbon capture and sequestration will be used in the reduction of the carbon dioxide. The hindrances that are associated with technologies, finances, policies and organization in general will be determined and advised policies will be formulated for effectiveness implementation of the urban water cycle.
