The mineral water production equipment is a solution separation based on the pressure difference between the two sides of the membrane, based on the principle of mechanical screening. The pressure is usually
0.2MPa--0.6MPa, separation pore size 1nm--0.1μm, can be widely used in the separation, concentration and purification of substances. The ultrafiltration process has no phase conversion,
It is especially suitable for the separation of heat sensitive substances, and has good temperature resistance, acid and alkali resistance and oxidation resistance. It can be used continuously for a long time under the conditions of 60 ° C and PH at 2-11.
The mineral water production equipment uses the cation resin to soften the source water. The main purpose is to let the cation resin adsorb calcium and magnesium ions in the water (the main component of scale formation), the mineral water equipment reduces the hardness of the source water, and can carry out the intelligent resin. Regeneration, recycling.
First, the characteristics of mineral water production equipment
The tap water pressurizing pump is used to increase the system water supply pressure, and the multi-media filter can remove suspended matter, impurities and the like in the water. Activated carbon filter
Remove residual chlorine, odorous substances and odorous gases in water to improve taste
The precision filter further removes impurities from the water, and the hollow ultrafilter can disperse the water.
Various harmful substances such as plastids, colloids, phenolic compounds, chlorides, bacteria, etc. are removed, and various beneficial minerals in the water are retained.
Second, the production process of mineral water production equipment
1
Raw water tank
Store raw water for sedimentation of large sediment particles and other precipitable substances in water. At the same time buffering the water pressure in the raw water pipe is unstable to the water treatment system
The impact of the system. (such as pressure sensing reaction caused by low or too high water pressure).
2, the original water pump
Constant system water supply pressure, stable water supply.
3, multi-media filter
The filter with multiple filtration layers is mainly used to remove the sediment, rust, colloidal substances, suspended solids and other particles containing more than 20um in the raw water. It can be backwashed by manual valve control or fully automatic controller. Flush and other operations. Ensure the water quality of the equipment and extend the service life of the equipment.
4, activated carbon filter
The system uses a shell-shell activated carbon filter. The activated carbon not only adsorbs electrolyte ions, but also performs ion exchange adsorption. Adsorption by activated carbon
It can also reduce the oxygen consumption (COD) of potassium permanganate from 15mg/L (O2) to 2-7mg/L (O2). In addition, the surface is adsorbed and replicated due to adsorption.
The concentration increases, thus also catalyzing, removing pigments, odors, large amounts of biochemical organic matter, reducing the residual chlorine value of the water and pesticide contaminants and removing trihalides (THM) and other pollutants in the water. Manual valve control or fully automatic controller can be used for backwashing, flushing and other operations. Ensure the water quality of the equipment and extend the service life of the equipment. At the same time, the equipment has a self-maintenance system and the running cost is very low.
Virus Specimen Collection Tube
Inspection principle:
It can perform protein denaturation on fresh clinical virus samples to inactivate the virus, prevent secondary transmission of infection, and ensure the safety of transportation and testing personnel.
♣.Structural composition: Combination of cotton swab and transport medium (VTM).
♣. Product requirements:
The product should be airtight, avoid high temperature, avoid direct sunlight storage. It should be used in a clean, hygienic, pollution-free, and temperature-friendly environment.

♣. How to use
â‘ Before sampling, mark relevant information on the label of the sampling tube.
â‘¡. Sampling with the corresponding cotton swabs.
â‘¢ After the collection is completed, quickly put the cotton swab into the collection tube, break the part higher than the sampling tube, and tighten the tube cover.
â‘£. For the specific sampling method, please refer to the following:
a) Nasal swab Gently insert the sampling head into the nasal cavity, stop for a while and then slowly rotate to exit, immerse the collected specimen in the Xiangxiang solution, break the excess part and discard it, and tighten the sampling tube cover.
b) Pharyngeal swab: Wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with the sampling head, immerse the collected specimen in the sampling solution, break off the excess part and discard it, and tighten the cap of the sampling tube.
c), Mycoplasma Chlamydia, Ureaplasma specimen collection
Male: Insert the sampling head into the urethra about 2cm and rotate, stay for a while and then exit, and immerse the collected specimen in the sampling solution.
Female: Wipe the mucus of the cervical orifice, insert the sampling tip into the cervical canal for 1-2 cm for sampling, immerse the collected specimen in the sampling solution, break off the excess part and discard it, and tighten the cap of the sampling tube.
♣. Precautions
1. After the virus is collected, the disposable sampling swab should be completely inserted into the preservation solution, so that the virus can be retained to the greatest extent possible.
â‘¡ The collected specimens must be sent for inspection in time.
â‘¢. It is forbidden to use products with damaged packaging and expired validity period to prevent pollution.
This single-use Virus Sampling Tube is used for in vitro diagnosis. It cannot be used for human or animal oral or external use. If swallowed, it may cause serious events; it is irritating to eyes and skin. If it is not splashed into the eyes, rinse with water.
