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

Water pollution Water pollution is the contamination of water bodies . Mostly water pollution occurs in lakes‚ rivers‚ oceans‚ aquifers and groundwater. Water pollution occurs when pollutants are directly or indirectly discharged into water bodies without adequate treatmentto remove harmful compounds. Type of water pollutions There are many types of water pollution because water comes from many sources. Here are a few types of water pollution: 1. Nutrients Pollution Some wastewater‚ fertilizers

storage of rainwater for reuse before it reaches the aquifer. Uses include water for garden‚ water for livestock‚ water for irrigation‚ etc. In many places the water collected is just redirected to a deep pit with percolation. The harvested water can be used for drinking water as well if the storage is a tank that can be accessed and cleaned when needed. Rainwater harvesting provides an independent water supply during regional water restrictions‚ and in developed countries is often used to supplement

Philosophy 101 8/4/2014 Saving Water Water is a natural resource that many take for granted; yet it is one we are quick to mourn when it is not present when we need it‚ such as for drinking‚ or when a disaster occurs that thrusts its vulnerability to the forefront of our daily news. Twenty years from now‚ will you have abundant‚ clean water? Unfortunately‚ the answer may be no‚ unless you want to buy water at $3 per gallon. People are already starting to conserve water. Many communities are putting

and sale of Nestle bottled water. As soon as Nestle began extracting and bottling the water from natural sources throughout the United States municipalities and citizens took notice. Nestle is the largest extractor of water in the city of Detroit and state of Michigan. Although other bottlers such as Coca-Cola and PepsiCo also extract water‚ Nestle has been credited with doing the great amount of environmental damage. “Opponents say Nestle’s pumping is lowering water levels in local creeks and

Deionized Water vs. Distilled Water Deionized and distilled waters are both processed forms of water. Deionized water is produced by filtering water to the point where it is free of ions. This ion-free water will strip ions from surrounding material‚ acting like a super-solvent. This is often used in semiconductor and other high-tech processing as a "soft" solvent and relatively cheap cleaning fluid. Distilled water is most often produced by vaporizing less pure source water (tap‚ salt or even

Salt Water or Fresh Water‚ Which Would You Prefer? Many people wonder‚ what big differences are between salt water and fresh water? Is it just water with salt versus water without salt? Those are some common questions people have. Most people ask about the differences‚ but they forget about the similarities of salt water and fresh water‚ as well. Did you know that Salt water and fresh water have very different plant and animal life? There are also a few complex fish that can live in both

Wastewater Wastewater is any water that has been adversely affected in quality by anthropogenic influence. It comprises liquid waste discharged by domestic residences‚ commercial properties‚ industry‚ and/or agriculture and can encompass a wide range of potential contaminants and concentrations. In the most common usage‚ it refers to the municipal wastewater that contains a broad spectrum of contaminants resulting from the mixing of wastewaters from different sources. Sewage is correctly the

property of water is that it is an excellent solvent. This is because of the chemical composition and physical attributes of water. Since water is polar‚ it allows water molecules to become attracted to different molecules. The attraction can be so powerful that it can disrupt the attractive forces of the different molecules. For example‚ water can be heavily attracted to salt that it can disrupt the forces that hold sodium and chloride‚ therefore dissolving it. The second property of water is its high

What my project is about: I will be comparing results from water testing I did at two different water bodies to prove that the catchment area has an influence over the water quality in the different water bodies. The first water body I tested was the small dam in the bokkie park situated in between residential areas and in the middle of a piece of land solely used for animals. The second water body I tested was the small dam across the road from the Trinity Church in Boksburg on Rondebult Road‚ which
