Product description
Parameters
Electrodeionization (EDI) is an electrically-driven water treatment technology that uses electricity, ion exchange membranes and resin to remove ionized species from water.<br
It is wisely combined electro dialysis with ion exchange technology,by using of high-voltage electrodes at both ends to drive charged ion in the water to move,and with the ion exchange resin and selective resin membrane to accelerate ions moving,so as to achieve the purpose of water purification.

2. PH: 6.0-9.0
3. Temperature: 5-35’c
4. Hardness: Less than 0.5ppm
5. Organics: Max 0.5ppm, Recommend 0 ppm
6. Oxidizers: Max 0.05ppm
7. FE MN: Max 0.01ppm
8. Silica: Max 0.5ppm

Chemical Resistant Diaphragm Dosing PumpChemical Dosing Pumps are compact, positive displacement pumps that are designed to pump an extremely accurate flow rate of chemicals or other substances into a water or gas stream. These dosing pumps work by taking a certain amount of liquid into the chamber and inserting the chemical into pipes or tanks that harbor the fluid that is being dosed. The pump is energized mainly by electric motors or an aeration actuating element and utilizes a controller than navigates the pumps (controls flow rate) and switches the power on and off.Chemical Resistant Diaphragm Dosing Pump0.00Chemical Dosing Pumps are compact, positive displacement pumps that are designed to pump an extremely accurate flow rate of chemicals or other substances into a water or gas stream.
