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

Water is composed of Oxygen and Hydrogen. It is found in wells‚ springs‚ ponds‚ rivers‚ canals and oceans. About one fourth of the earth is covered with water. It is obtained mainly from the rains. Water is really a precious gift of Nature. It has no taste‚ no smell‚ and no colour. The other name of water is life. We cannot live without water. We drink it‚ cook our food with it‚ bathe in it‚ and wash our body and things with it. The farmers need water for growing crops or plants. With water‚ the

Water Availability and Water Quality Water is the most precious natural resource that exists on our planet. Every living thing needs water in order to survive. If water becomes polluted‚ it loses its value and can become a threat to our health. Although we as humans recognize this fact‚ we disregard it by polluting our rivers‚ lakes‚ and oceans. Water availability has become a great concern in our world today. Out of all the available water on earth‚ only 3 % of it is fresh water. 77% of this

AUTOMATIC WATER PUMP CONTROLLER The automatic water pump controller is used to control the water pump motor. The motor gets automatically switched on when water in the overhead tank (OHT) falls below the lower limit. Similarly‚ it gets switched off when the tank is filled up. Built around only one NAND gate IC (CD4011)‚ the circuit is simple‚ compact and economical. It works off a 12V DC power supply and consumes very little power. The circuit can be divided into two parts: controller circuit and

Properties of Water Water is essential for life as we know it on earth. It is used by plants and animals for basic biological processes which would be impossible without the use of water. The origin of all life can be traced back to the water in the Earth’s precambrien seas. Water is also the universal solvent. It reacts with more elements and compounds than any other substance known to man. Water is a polar molecule made up of on atom of hydrogen and two atoms of oxygen. It is attracted

Water Crisis in UAE Introduction Water crisis refers to the situation where the available water within a geographical location cannot meet the water needs of the population in that location. This prevalent situation has drawn considerable attention in most countries due to its severity to humanity. Because of the tripling of the population in the 21st century‚ the demand for water has remained considerably higher than the available clean and safe water. Despite the fact that the earth is covered

Water Conservation Our drinking water can come from wells‚ rivers and reservoirs. Our water usually does notcome from the ocean‚ because it is too salty to drink. The water in our rivers and reservoirscomes from precipitation. The amount of rain on average is almost the same from year toyear‚ while the population on the other hand is increasing. That means there is less water for each person in the future.Everyone should try to conserve water. However‚ it matters most to conserve where the population

Shortage of water in Pakistan As we all know‚ Pakistan is facing severe shortage of water. There are two main reasons‚ one due to persistent droughts---which is beyond the control of a man‚ and the other due to miss-management of water resources. Impact on economy / society * Less water means less agricultural yields‚ meaning they cannot fulfill the food requirements of the nation‚ so they need to be dependent on other countries. * Due to less production of main crops‚ which are wheat‚
