ion-exchange Water Softener
A Harvey water softener is a device about the size of a computer tower. It gets plumbed in to your house, usually underneath the kitchen sink, and it takes the water as it comes into the house and runs it through a pair of softening tanks, which remove the minerals from the water that cause limescale and soap scum.
Every so often, the machine flushes the minerals from the tanks by rinsing them through with salt water, which is why it needs to be kept topped up with blocks of salt. Aside from that, you don't need to do anything to keep it running.
At the heart of a water softener is its ion-exchange resin. The resin consists of microscopic beads, and as the hard water passes through them, they trap the magnesium and calcium ions that are in it, so the water comes out totally soft. This is a fairly simple process that's been in use for over ninety years.<o:p>
Working configuration:singe-valve and dual-tank,one tank is working,the other tank is standby,alternative regeneration for continuous 24 hours working.
01. By means of Absorbing the calcium and magnesium ions in water with resin, since the hardness of water is mainly composed of calcium and magnesium, in general, we adopt cation exchange resin (softener), replace Ca2+, Mg2+ (main ingredients for scale) in water, as the increase of Ca2+ and Mg2+ in resin, removing performance on Ca2+, Mg2+ of resin will gradually reduce.
02. When the resin has absorbed a certain amount of calcium and magnesium ions, it must be regenerated, the regeneration process is that flush resin layer with the salt water in salt box, replace hardness ion out of the resin again, and discharged from the tank with waste liquid of regeneration, then resin resumed the function of softening and exchanging.
03. The principle of sodium ion exchange and softening treatment is to exchange cation in the raw water with resin, hardness constituents Ca2+and Mg2+ in water exchange Na+ in resin, thus absorb the Ca2+and Mg2+ to make the water to be softened.
2RNa + Ca2+ = R2Ca + 2Na+
2RNa + Mg2+ = R2Mg + 2Na+
After the water treated by sodium ion exchanger, the Ca+ and Mg+ were superseded by Na +.
Application scope of softener
Mainly used in industry and civil water softening preparation, such as Boiler feed water make-up water, air conditioning system make up water, heat exchanger, power plant, chemical, textile, printing and dyeing, bio-pharmaceutical, Electronic system and water pretreatment.
Type choice:
Softener equipment applies cation resin for softing raw water,its main target is to use cation resin to adsorp (main parts of ),encreasing the hardness of raw water.
1. Users can choose manual operation control system for saving cost.
2. If users using for 24 hours can accord to water using time choosing for rebirth
3. Uses can according to water quality requirement:first grade multi-media filter,which can remove mud,rust,colloid and suspension in water.Second grade activated carbon filter,which can remove color,olfactory,biochemistry organic in water and encrease the left oxygen value and pollution in water.Third grade equiped softener equipment.
4. Effluent water capacity achieves the water supply of national low-pressure bioler.
5. Time control- type;flow control- type.In working ,apply single-tank,double-tank and multi-tank etc. other varied combination method.When choosing,users can choose as their needs.In operation,it has not only automatic function,but also is manual operation.
Technoloty index and working
Water pressure:0.18-0.6Mpa
Working temperature:1°c-55°c
Hardness of raw water: <8mmol/L
Operation method:manual/automatic
Hardness of effluent water: ≤0.03mmol/L
water flow: 0.3-100 m3/hour
Rebirth method:
Control method: time or flow
Working electric: 220V/50Hz
Mineral Tank:
The mineral tank is where the action is. It is where the water filtration takes place and the hard water is softened (calcium and magnesium are removed).
Brine Tank:
The brine tank is where a highly concentrated solution of salt or potassium is stored.
Control Valve:
The control valve is the device that controls the flow of water into and out of the mineral and brine tanks during regeneration.
Usage:
System automatic water softener widely used in steam bioler,heating bioler,exchanger,air conditioner, and other systems water softener,also used in hotel,restruant,office, and other life water treatment and food,drinking,wine,washing,textile,chemical,medicine and other industrial softener water treatment.
