Water waste management is the field of handling waste water to make it suitable to either be recycled into a water system or to be disposed of in an environmentally-conscious manner. This is one of the larger problems facing most major cities in the modern world‚ with overflow causing severe pollution problems and increasing population densities stretching existing infrastructure to the breaking point. Both mechanical and biological processes are used to manage wastewater to get rid of undesirable

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

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

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

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
