Why Do Water Dispenser With Filtration Discharge Wastewater at Work?
In order to ensure the safety of drinking water, people buy water dispenser with filtration one after another, but many people find that wastewater is discharged after buying water dispenser with filtration, so they wonder why Water Dispenser With Filtration(KOKOELECTRIC) discharge wastewater at work? Will it affect water quality?
1. Return the wastewater to the inlet end of the water dispenser with filtration.
The process of reverse osmosis water production is actually a process of concentration. In the process of water production, the concentrated salt in the system must be drained to maintain the stability of the system. If the wastewater from the water dispenser with filtration is returned to the water inlet end of the water dispenser with filtration, this means that for the water dispenser with filtration, only salt flows in and no salt is removed, and the salt content of the water in the water dispenser with filtration will increase rapidly, eventually causing the osmotic pressure of the water to exceed the pressure provided by the booster pump, resulting in the water dispenser with filtration not producing water. At the same time, due to the increase of salt content, some insoluble minerals begin to deposit on the surface of the membrane, resulting in blockage and damage of the reverse osmosis membrane. This damage is usually irreversible and only the reverse osmosis membrane can be replaced.
2. Regular intermittent discharge of wastewater
There are many such products on the market. Water dispenser with filtration work for several minutes and discharge wastewater for tens of seconds. This method is also undesirable. The recovery rate of the reverse osmosis membrane is 100% during the period when the water dispenser with filtration does not discharge wastewater. At present, no reverse osmosis membrane in the world can achieve a recovery rate of 100%. As a result of such use, trace insoluble salts in water are rapidly deposited on the surface of the membrane, which leads to reverse osmosis blockage and severely shortens the service life of the reverse osmosis membrane. For this type of machine, users usually have to replace the reverse osmosis membrane within 6 months, while for a reasonable system, the service life of reverse osmosis is usually about 3 years.
3. Store the wastewater for other purposes.
This method is to use a large pressure barrel to store the wastewater and then release it for use when needed. This method is the only feasible method at present because it does not substantially change the operating parameters of the water dispenser with filtration.
Through the above introduction, I believe you will find that the wastewater produced by the water dispenser with filtration is a normal phenomenon, you need not panic, and the discharged wastewater can be used for other purposes without causing waste of resources.
