When there is a shortage of water or electricity in the laboratory or a large amount of water is needed in a short period of time, the water storage tank can temporarily solve the demand for tap water. However, due to the customer's application habit and many various factors, the laboratory ultrapure water machine equipped with a storage tank still has certain safety hazards.
1. Deteriorating water quality
After the water storage tank is used for a period of time, it is easy to leak steam, resulting in insufficient pressure, and some pure water will remain in the water storage tank. This water becomes stagnant water that cannot flow. Dead water is prone to grow bacteria and produce extracellular matrix. Not only will it reduce water quality, but it will also cause microbial poisoning in the back-end development and purification module.
2. Secondary pollution
Some water storage tanks use cheap industrially produced plastics as raw materials, which not only have poor airtightness, but are also very easy to mix with environmental pollution chemicals. The inside of the shell is uneven and easy to hide dirt. The overflow is connected to the underground drainage pipe, which is unfavorable for the maintenance of water quality.
3. Safety hazards
The water level line magnetic induction equipment used in some water storage tanks impedes that hydropower projects cannot be separated, which poses a certain safety risk.
4. Not easy to disinfect
Because of the small size of the inlet and outlet, customers cannot carry out detailed cleaning, disinfection and sterilization. This promotes the water storage tank to become a seedbed with increased germs, and the malignant change of the water body continues to increase.
5. Damaged consumables
As the working pressure of the water storage tank rises, the quality of purified water will gradually deteriorate, resulting in a sharp drop in the exchange volume of the ultra-purification column and a reduction in service life; the production of pure water will gradually shrink, leading to the destruction of the RO membrane.
In order to prevent safety hazards such as malignant changes in water quality of laboratory ultrapure water machines, secondary pollution, and destruction of consumables, customers and friends should pay attention to the following:
1. Material of water storage tank
Choose a water storage tank with high-quality materials, good airtightness, and air purification. While ensuring stable pressure, it reduces environmental pollution and total residue mixing.
2. Location of water storage tank
Do not place the water storage tank in a place where the sun is irradiated, otherwise it will easily lead to environmental pollution of microbial strains and even the breeding of many algae plants.
3. Install sterilization device
Once germs and other microbial species are caused in the water storage tank, all system software will suffer environmental pollution. It is proposed to install ultraviolet sterilization equipment in the water storage tank and purified water pipeline to disinfect microbial strains in all directions.
4. Water intake method
In order to obtain high purity water, it is convenient for normal use. Pay attention to water collection after the previous water is exhausted to prevent bubbles from being caused when water is collected. If there is a requirement for water storage, the pure water storage time should be controlled within 24 hours. If there is no requirement for tap water for a long time, the pure water in the water storage tank must be drained.
The safety risks of the laboratory ultrapure water machine equipped with water storage tanks are shared here. It is recommended that you choose the right product when making a choice, which can save a lot of troubles.
