Water treatment system

 
Water treatment system is meant for water metering, warming and desired temperature maintenance.

Water warming and feed to collection bowl are performed through electric boiler and circulation system. Metering volume is specified by operator. System capacity is up to 17 m3/hr. Metering range is 1-9999 l.

The system consists of heating, collecting and metering parts installed on one frame.

Control panels adjust all units operation. Cold water is supplied to the system through input section where ball hand crane and solenoid operated hydraulic valve are situated. Solenoid operated hydraulic valve stops feed when vessel is full. 

Water enters the boiler, is heated to specified parameters and then is fed to the bowl. When desired volume of water is supplied, heated water feed stops.

Then circulation pump starts. Water collected in the bowl circulates through the boiler. So temperature stays the same. Metering start doesn’t depend on heating and level in the bowl. Metered water quantity is adjusted with the control panel.
