A 2007 study finds that discharge of untreated sewage is the single most important cause for pollution of surface and ground water in India. There is a large gap between generation and treatment of domestic waste water in India. The problem is not only that India lacks sufficient treatment capacity but also that the sewage treatment plants that exist do not operate and are not maintained.[1] The majority of the government-owned sewage treatment plants remain closed most of the time due to improper

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

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

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

Osmosis and water potential Aim of the experiment: Finding the water potential of potato. Biological principles: Independent variable: concentration of the solution. Dependent variable: percentage changed in weight of the potato strips. Controlled variable: size of the potato strips‚ it can be controlled by cutting the length of the strips. Procedure: Table 1.

Fairchild Water Technologies‚ Inc. I. INTRODUCTION Fairchild Water Technologies was founded in 1980 by Eugene Fairchild. The company’s first product was a desalinator used by mobile home parks in Florida to remove salt from well water supplied to residents. As the desalinator became a huge success‚ the company expanded into the coastal region’s adjacent to the company’s headquarters in Tampa‚ Florida‚ and then to desert areas in the southwestern United States. By 2002‚ they had expanded

Investigating the Water Potential of a Potato. I have been asked to investigate the water potential of a potato. During my investigation I will not actually be able to measure a value for‚ as it is a pressure value (kPa). Osmosis is a special form of diffusion involving only water molecules. It is defined as "The passage of water from a region of high water potential to a region of low water potential through a partially permeable membrane" Definition of Water Potential. The potential for water to move
