The pure water equipment adopts advanced reverse osmosis technology as the core separation technology, which plays a great role in the laboratory. As a common equipment in the laboratory, the water inlet conditions of the ultrapure water machine also play a crucial role in the future experimental results. In order to give full play to the working effect of the laboratory ultrapure water machine, the following is a detailed understanding of which water inlet conditions will affect the experiment:
1.Effect of inlet pressure on reverse osmosis membranes.
It is not possible to affect the filtration effect in terms of the pressure of the inlet water, but the pressure of the reverse osmosis membrane is also increasing after the inlet pressure of the pure water equipment manufacturer increases, the water yield will be greatly improved, and the filtration effect will not change much, but the permeate will dilute the salt through the membrane, thereby increasing the desalination efficiency. After the inlet water pressure exceeds a certain value, it will be higher than the ** rate, and the concentration is too poor, which will lead to an increase in the excess salt through the water, offsetting the increased permeate and resulting in no increase in the desalination rate.
2. The influence of inlet water temperature on the reverse osmosis membrane.
The conductivity of the membrane in the process of long water is quite sensitive to the stability of the influent water, which leads to the increase of water temperature and the continuous increase of throughput, and the water yield will also increase slightly for every 1 degree increase in the influent water temperature.
3. The influence of influent pH value on reverse osmosis membrane.
The pH of the source water has little effect on the water production, and has a great impact on the desalination rate. Desalination peaks at pH levels around seven to eight.
4. The effect of influent salt concentration on reverse osmosis membrane.
The osmotic pressure of the pure water plant is the deep desalination of all R&D and total organic matter in the water, and the greater the concentration difference, the lower the desalination rate.
As a new separation, purification and concentration method, membrane separation technology has the characteristics of low energy consumption, high efficiency, simple process and low investment compared with traditional separation operations (such as evaporation, extraction, precipitation, coagulation and ion exchange resins, etc.). This makes it ideal for use in areas such as laboratories where water quality is required.
With the improvement of inspection equipment and inspection technology, the reduction and elimination of other error factors, the influence of water quality on experimental results is very important. Especially in recent years, with the development and transformation of testing technology, water quality has not only become a bottleneck for improving quality, but also the key to the success or failure of some experiments (such as cell culture, etc.). The quality of the water directly determines the results of the experiment, once the inlet water quality does not meet the requirements, it will bring unnecessary losses to the laboratory, so the inlet conditions of the ultrapure water machine are particularly important.
