Model：DR10 Single-tank Automatic Softening Valve
Characteristics of Performance
1、It adopts the backflow regeneration controlling principle of floating bed; The quality of water is high whereas the consumption of salt is low;
2、No hard water runs through the equipment for the industrial type. It is suitable in some situations where the requirements for the quality of water are high, such as boilers.
3、The sealing for the core of planar valve adopts ceramic non-wear type and guarantees reliable usage.
4、The Chinese (or English) operating interface shows the instant and accumulated amount of water.
5、 There are two modes to choose from: full-flow pattern and time mode. It has the memory function of cutting off the electricity and water.
6、 It is easy to be installed and adjusted and needs no operation from the user.
7、 it can be forced to be set regeneration time of day in flow pattern.

1、 Regeneration
----When raw water passes by the ejector, brine water(concentration 20%) will be absorbed into the valve by the ejector and get diluted (concn. 5%). Then it will enter the top of the swap tank and the layer of resin. The Calcium ion and Magnesium ion that have been swapped will be discharged through lower water locator.
---In the regenerating process, the resin at the top of the swap tank will contact the freshest regenerating liquid first. The salty water passes through multiple layers of resin, which will result in an imbalanced shape of the resin layer. |

|
2、 Cleaning
----Raw water enters the top of the swap tank and resin layer, and continues to wash the swapped Calcium and Magnesium ions. At last, it passes through the lower water locator and get discharged through the center pipe.
----In the cleaning process, another part of raw water supplements water to the brine tank simultaneously. When the level of water reaches the brine valve floater, water supplementation will stop. |

3.Softening
----Raw water passes through the center pipe, lower water locator and reaches the bottom of the swap tank. Water passes the resin layer from bottom to top and after raw water having been softened; it runs out through the upper water locator.
----In the softening process, resin layer around the lower water locator will form floating layer or bed which will facilitate distributing water and making full use of the resin.
In the softening process, water flows in the opposite direction with regenerating water. If the softening process is complete, then the quality of water can be guaranteed |

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 YanLiang absorption.
