The equipment adopts multi-function valve to rotate and change the water flow direction and flow control, so that the deaerator can complete water preparation, backwashing and washing. It is equipped with microcomputer controller and water level switch to realize automatic and continuous operation of the equipment.

The iron removal ion exchanger connected behind the filter deaerator can remove iron ² It can also be used as the secondary treatment of the former stage softened water to further eliminate the components of boiler scale and water slag.

The ANRT series filter deaerator uses the sponge iron filter material, which has a strong oxygen consumption capacity. It is a kind of porous material with high iron content. It has the characteristics of advanced production technology, good activity, large area, excellent deaeration effect, low working temperature, no hardening, no pulverization, no harmful substances, low backwashing frequency, strong regeneration ability, long service life, etc. working principle

When neutral or alkaline demineralized water (demineralized water) passes through the filter layer, the reaction occurs as follows: 2Fe+2H2O+O2 → 2F (OH) 2 ↓ 2Fe (OH) 2+H2O+1/2O2 → 2F (OH) 3

Fe (OH) a is a yellow flocculent which can be removed by backwashing regularly. In the deep layer of filter material, a small amount of Fe ²+ The deoxidized water enters the iron removal ion exchanger and is removed. The reaction is as follows:

2RNa+Fe2+→R2Fe+2Na+

After the resin fails, use NaCl solution for regeneration. The reaction is: R2Fe+2Na+→ 2RNa+Fe+ Fe ²+ Wash with water to remove.
