in this paper, productivity of and demand for water throughout eqlid’s sugar beet growers in 1385 were investigated. to address the objective 100 growers were selected using two-stage cluster sampling, then required dataset was obtained by interviewing and completing questionnaire. in order to study factors affecting sugar beet production, cobb-douglas production function was applied. based on ...

The phenomenon of calcium carbonate crystal growth from aqueous solutions on surfaces widely occurs in systems where carbonate and bicarbonate ions are present, such as in domestic systems, waste and drinkable water treatment systems or industrial apparatus where water is used. Crystal growth leads to the formation of mineral scale which reduces the performance of membrane materials in equipmen...

The primary objective of the water purification process is to remove harmful chemical compounds and microorganisms from sources in order produce suitable for human consumption. Water satisfies demand drinkable water, which a requirement many industries, including medical, pharmaceutical, among others. Access purified single most important factor determining nation’s strength prosperity. As cons...

Water is one of the most precious resources in world. The ability to protect world’s water supply an essential priority for encouraging reuse, and developing strategies encourage recycling a key action help achieve this priority. means using again previously used another purpose. Recycled can fulfill demands as long it adequately treated guarantee that its quality appropriate use. Recycling red...

The paper presents a cost-effective device designed for measuring and monitoring the TDS (total dissolved solids) level of drinkable, surface (lakes, rivers) and/or industrial waters. Providing a first reading of potential water pollutions, the device is dedicated to the sectors of environment and consumer protection. The device was implemented and a series of continuous measurements is depicte...

Short-term water demand modeling plays a key role in urban water resources planning and management. The importance of demand prediction is even greater in countries like Iran with frequent periods of drought. Short-term water demand estimation is useful for planning and management of water and wastewater facilities such as pump scheduling, control of reservoirs and tanks volume, pressure manage...

This paper presents some aspects concerning the estimation of the parameters in the input-output chlorine residuals models of drinking water distribution networks (DWDNs) used for transportation of treated drinkable water from the water treating plants to consumers. To kill the microorganisms that can cause the waterborne ills, disinfection is usually the final treatment stage in the drinking w...

background: in the present study, histopathological effects of chronic exposure to sodium arsenate in drinkable water were studied on a quantity of organs of rat. methods: rats were divided into two groups, group i served as control group, were main-tained on deionized drinkable water for 2 months, and group ii the study group were given 60 g/ml of sodium arsenate in deionized drinkable water ...

As engineers, a confliction readily appears in regards to cost efficiency against quality. Civil Engineer A of Peace Corps was assigned the task of the design and building of a desalination though electrodialysis plant in rural Uttar Pradesh, India. Desalination is the process of removing high salt contents from groundwater in order to render it drinkable. Of the total volume of water on Earth,...
