In the laboratory, such as animal and plant cell culture, liquid chromatography, mass spectrometry, plasma coupling spectroscopy, atomic fluorescence, etc., most of the experiments usually have very strict requirements on the water quality of the experiment, not only the water resistivity but also the water quality. The organic matter, particulate matter, bacteria and pyrogens in the plant have strict requirements.

The laboratory Ultra Water Purification Systems can effectively solve the complex problem of laboratory water use. Water Purification Systems can be prepared through small equipment, making the operation simpler and more convenient, and improving work efficiency. At the same time, on the basis of ensuring water quality, laboratory ultrapure water equipment can reduce water production costs.

Operating Principle of Water Purification Systems

The working principle of the Water Purification Systems is to apply a certain pressure to the water so that the water molecules and ionic mineral elements pass through the reverse osmosis membrane, and most of the inorganic salts (including heavy metals), organic matter, bacteria, viruses, etc. Dissolved in the water Impermeable reverse osmosis membrane, so that the pure water penetrated and the concentrated water-impermeable are strictly separated.

The pore size of the reverse osmosis membrane is only 0.0001 microns, and the diameter of viruses is generally 0.02-0.4 microns, and the diameter of ordinary bacteria is 0.4-1 microns. The water from the Water Purification Systems meets the drinking water standard.

The purification process of Smart Water Purification Systems

The Heal Force Smart ultrapure water series is Smart Ultra Water Purification Systems developed by Heal Force. It has a number of patented technologies; the all-plastic mould design can use tap water as the inlet water, and simultaneously prepare analytical grade pure water and ultrapure water, or The RO water and distilled water are directly used as the feed water to prepare ultrapure water to meet the needs of water in many fields such as hospitals and colleges.

Water Purification Systems

Common impurities in natural water include soluble inorganic matter, organic matter, particulate matter, microorganisms, soluble gas, etc. What the ultrapure water machine does is to remove these impurities as much as possible.

The smart ultra water purification machine generally divides the water purification process into four steps, pretreatment (primary purification), reverse osmosis (production of pure water), ion exchange (can produce 18.2MΩ.cm ultrapure water) and terminal treatment (Produce ultrapure water that meets special requirements).

1. Pretreatment

First remove impurities that affect the reverse osmosis membrane: including large particulate matter, residual chlorine, and calcium ion and magnesium ion.

*Reminder: According to the difference of influent water quality, different treatment units need to be equipped. Improper operation during pretreatment will cause subsequent purification to fail to achieve the desired results and shorten the life of major components such as reverse osmosis membranes and ultra-purification columns. The timely replacement of pretreatment consumables will help the long-term stable operation of ultrapure machines.

2. Reverse Osmosis

Using a high-pressure pump to provide a pressure greater than the osmotic pressure of the high-concentration solution, water molecules will be forced to pass through the semi-permeable membrane to the low-concentration side.

Reverse osmosis is a very effective technology in water purification systems, which can filter out 90%-99% of most contaminants (including inorganic ions). It is used as a previous treatment method and can significantly extend the use of deionization exchange columns. time.

In order to prolong the service life of the reverse osmosis membrane and improve the filtration efficiency of the reverse osmosis membrane, the Heal Force Smart-N ultra-pure water system is equipped with a restrictor valve at the outlet of the water, combined with the reverse osmosis flow limitation design, so that the reverse osmosis membrane is always soaked in water , So as not to affect life due to drying.

3. Ion Exchange

The positive ions in the water are exchanged with the H ion in the ion exchange resin, and the negative ions in the water are exchanged with the OH-ion on the ion exchange resin, so as to achieve the purpose of purifying water.

*Reminder: After ion exchange, the level of water quality mainly depends on the quality of ion exchange resin and the exchange efficiency of water and resin in the exchange column. The quality of ion exchange resin has a direct effect on the quality and service life of the ultra-pure water machine

4. Terminal Processing

According to the special requirements of the installation, ultra-pure water of ultra-low organic type, aseptic type, non-heat source type, etc. is produced.

There are various treatment methods for different requirements, such as ultrafiltration filtration method for removing heat sources, dual-wavelength ultraviolet oxidation method for reducing total organic carbon (TOC) in water, microfiltration to remove bacteria, etc.
