[70% Volume(L) of the Resin load] ÷ Hardness of raw water (mmol/L) |
1、 70% for resin cycle, and 30% effective utilization rate as protection layer, resin utilization and the resin filling rate (90%) and, when necessary, to fill the relevant. Soft water demand strict, raw water hardness higher should be considered when the effective utilization rate reduce cycle to increase the coating of method; Also can take use increases, heightening the tank to exchange.
2、the clean water should be set according to the site, to adjust the cleaning 2 minutes before the end of the drainage outlet tasteless for host.
3、 raw water hardness unit mmol/L
4、 the design and calculation of the resin used working exchange capability for 1000 mol/m 3;
5、 the design and calculation of saturated concentration of 20% salt water used;
6、 flow models under the clean water contains salt water box;
7、 time mode of regeneration, cleaning, softening the time should be each station according to the site and combining with the feed water pressure pressure flow curve calculations;
8、 choose exchange with operating velocity can no more than 55 m/h as reference, choose the same diameter of the highest exchange cans. Series
9、 the table above flow parameters set, renewable (rise) is through the jet of water injection quantity, and is not Yan Liang absorption.
