What is a water treatment plant?
Water treatment processes are applied to surface water sources. Typically, a water treatment plant (WTP) comprises intake, and pumping to treat water for consumption [1-4]. The designs of a unit or some units for WTPs are available [5-10].
What are the units of water treatment plant (WTP)?
Understanding the effect of any unit of Water Treatment Plant (WTP) on the performance of the other units is very important in optimal design of a WTP. In some of the WTP a Primary settling is done in the unit of Pre-Sedimentation Tank (PST) in entrance of raw water to the WTP. In some WTP, the unit of PST is used only in flood condition.
What data is required for specifications design of water treatment facilities?
The following is a list of possible data required for specifications design of water treatment facilities. The size and complexity of the process system and structures should govern the amount and detail of the design data required. A. General Map Showing: (1) A key map locating the general map area within the State.
What is the average discharge of a water treatment plant?
The calculations and detailed drawings of the units were displayed, the average discharge and population of used for the WTP design were 60,000 m3/day and 200,000, respectively. In addition, the calculation required some of the parameters to be estimated as field data, which were taken into consideration.
What is a water treatment plant?
Water treatment plant (WTP) can be described as water processing to attain water quality that meets specific end-user or community objectives. A WTP's performance assessment is a method for measuring functioning efficiencies based on certain performance indices such as degree of removal of pollutants such as turbidity, color, suspended impurities, etc. The present study aimed to evaluate the performance of Qandil WTP units, Erbil City, Iraq. For assessment of the WTP units by turbidity removal efficiency, water samples were collected from raw water, after clarification, after filtration, and storage tank. Obtained removal efficiencies for the sedimentation unit, filtration unit, after disinfection, and the entire Qandil WTP were 86.83 %, 91.28 %, 31.26%, and 99.29 %, respectively. Also, water quality index (WQI) for the WTP was studied. WQI assessment was made by testing 14 physicochemical and bacteriological drinking water quality parameters such as turbidity, pH, electrical conductivity (EC), total dissolved solids (TDS), total alkalinity, total hardness, calcium (Ca), chloride (Cl), Sulfate (SO4), magnesium (Mg), sodium (Na), potassium (K), Nitrate (NO3), and total Coliform. It has been found that turbidity, EC, total alkalinity, and total hardness had more effect on drinking water quality. WQI for Qandil WTP was 43.29 and it regarded as excellent level.
What is a WTP?
This work presented the design steps and calculation for each units of the water treatment plant (WTP), due to it’s important role domestically and drinking purpose. It also illustrated and designed the procedures of the water processing units by estimating water demand and designing the unit process. The objectives of this work were to estimate the water demand for a certain comminuity and to present design steps and calculations for the required units of a WTP.The design of the WTP units was applied to Greater-Zab River water for the selected location in Erbil City-Iraq. The quality and quantity of the Greater-Zab River water at various times were statistically analysed and presented.The units of the treatment processes involved intake, coagulation, flocculation, sedimentation, adsorption (optional), filtration, disinfection, storage, and pumping. The calculations and detailed drawings of the units were displayed, the average discharge and population of used for the WTP design were 60,000 m3/day and 200,000, respectively. In addition, the calculation required some of the parameters to be estimated as field data, which were taken into consideration. The outline results of each unit of the WTP were tabulated. It can be concluded that this work can be used as a source for designing other WTP units. A number of factors such as age of WTP, maintenance, economical and political situations, technical problems, and water demand had a graet impact on the removal efficiency of the WTP units.
