Water Technology Hardness of Water: Natural waters containing large quantities of dissolved salts of Calcium (Ca) & Magnesium (Mg) is called hard water. It is a characteristic of preventing lather formation of water with soap. Ca2+ & Mg2+ ions react with soaps which are salts of fatty acids (stearic or palmitic acid) to give insoluble scums or precipitates of calcium or magnesium stearate or palmitate. 2C17H35COO- + Ca2+ → (C17H35COO)2 Ca (scum) 2C17H35COO- + Mg2+ → (C17H35COO)2

desalination of water water‚ desalination of‚ process of removing soluble salts from water to render it suitable for drinking‚ irrigation‚ or industrial uses. The principal methods used for desalination include distillation (or evaporation)‚ electrodialysis‚ freezing‚ ion exchange‚ and reverse osmosis. In distillation saltwater is heated in one container to make the water evaporate‚ leaving the salt behind. The desalinated vapor is then condensed to form water in a separate container. Although long

creating hydraulic profiles for sewage treatment plants. Background During my last 20 years of experience working in the design of wastewater treatment plants‚ there were no two identical treatment plants. Each plant has its unique process‚ site layout and facilities. Consequently‚ hydraulic profiles are different and each plant was evaluated separately. The only similarity is the concept and the procedure that was followed in order to prepare the hydraulic profile. The following will

WATER Conservation INTRODUCTION: Water is essential for life on earth. Water is needed for growing food‚ keeping ourselves clean‚ generating power‚ controlling fire and most importantly to stay alive! This list is simply non-ending. This shows that water is an integral part of our daily life and we are heavily dependent on it. Water conservation: Refers to reducing the usage of water and recycling of waste water for different purposes such as cleaning‚ manufacturing‚ and agricultural irrigation

It shows how important water is in people’s daily life. So‚ just imagine how we survive if there’s not any water available. That’s the reason why water scarcity is one of the key environment issues of our time. This essay will identify some major causes and offer three solutions. The shortage of water resources is mostly

Despite the fact that water is something that has no taste‚ we still love it! Who doesn’t relish the feeling of a cool drink of water on a sweltering hot day? Approximately 70% of our body’s mass is made of water and according to a number of doctors‚ drinking a total of eight glasses of water a day fulfils the necessary requirement of this liquid our body demands. For a long time now‚ I have been searching regarding the benefits associated with water. Finally‚ after reviewing countless websites

and soil microbes. In some complex forests‚ there is also a well-defined lower tree layer. Forests are central to all human life because they provide a diverse range of resources: they store carbon‚ aid in regulating the planetary climate‚ purify water and mitigate natural hazards such as floods. Forests also contain roughly 90 percent of the world’s terrestrial biodiversity.[3] ---------------------------------------------------------------------------------------------------------------------

Business Opportunity Originated‚ Screened and Confirmed Viable: Water desalination is the removal of salts and dissolved solids from saline water (brackish or seawater)‚ also known as Desalting or Desalinization. In addition to the removal of minerals‚ the process removes most biological or organic chemical compounds. Desalination systems have been used to supply potable water for coastal communities and urban centers in more than 40 countries. Desalination plants operate in almost all of the world’s
