A level control inside the tank sends a signal to the valve to close when the tank is full Once the level in the tank is low the level control sends another signal to the solenoid valve to permit the flow of raw water into the system Every time the valve opens closes the system will start stop automatically A Flush solenoid valve is also provided with the unit This valve is under the control of a timer Periodically the valve opens to flush the membrane at low pressure This extends the periods between membrane cleans 4 2 System Components 4 2 1 Water Softener The water is Hard when Calcium and Magnesium are dissolved in it These salts precipitate out of the water causing scaling problems To prevent this situation the water is pre treated using a water softener Raw water flows through a media small plastic beads or chemical zeolite covered in sodium ions The calcium and magnesium ions are replaced with sodium ions As sodium does not precipitate out of the water the scaling problem is eliminated However the media is exhausted after certain amount of water has been treated This is because no more sodium ions are available to swap places with calcium and magnesium Consequently the media needs to be regenerated The regeneration process is very simple The media is soaked with a Sodium Chloride brine tank solution The sodium ions change places with the calcium and magnesium trapped in the media In this way the media is being
