Product Description:


1.  The reverse osmosis device is an equipment to purify the saline water with the action of pressure difference of semi permeable membrane,it is called reverse osmosis,as it is counter to natural penetration direction,


Different materials have different osmotic pressures,The reverse osmosis method to adopt larger osmotic pressures is used to obtain the purpose to separate,extract,purify and condense.



1.quartz sand filter

Raw water into the filter for a simple mechanical filter, mainly to remove suspended solids in water, colloidal particles and other large impurities in the water when the water pressure and the pressure difference over 10Psi (0.7kg/cm2) or water SDI> 5, the need for backwashing . In general, before running back wash once a day.


2. activated carbon filter

Activated carbon is used wood, coal, shell (nuclear) and other carbonaceous material through chemical or physical method activation made. It has a very large number of pores and specific surface area, which has a strong physical adsorption capacity, the effective adsorption of organic pollutants in water. Primarily to remove organic matter in raw water, chlorine, odor, color, etc., so that the original residual chlorine in water ≤ 0.1mg / l, effective protection of RO membrane from chlorine damage to parts of activated carbon typically 12 to 18 months to replace a The main residual chlorine as determined in raw water.

Under normal circumstances, it needs to backwash once a week.

3.  Precise filter

The third pretreatment, filter spray for the polypropylene melt, filter housing is ABS material, mainly to remove the vast majority of very fine suspended solids.

4.  Reverse osmosis plant

RO reverse osmosis equipment adopts the membrane separation to remove the water ions, organic matter, colloidal particles, bacteria and other impurities in the water desalination and purification to achieve the purpose. The principle is the solution to penetrate the membrane of water and separated, the water is leaking to the solution, the osmotic pressure between the two phases, if the solution phase on the pressure, so the pressure is the osmotic pressure, the solution to the water, the water will be the opposite infiltration to, obtained using reverse osmosis desalination of water. That is enough pressure in the raw water, through the permeable membrane and into pure water, no water through the membrane, the dissolved, suspended solids concentration increases gradually, as the concentration of water out.

Reverse osmosis plant can not only desalt, but also filter out the organic matter, bacteria and so on.  

5. This equipment uses mechanical filters, activated carbon filter as a pre-treatment, it is useful to remove the suspended solids in raw water, sediment particles, organic colloids, organic matter, odor, chlorine and other impurities. With control programmed device as a pre-desalination plant to remove most of the dissolved salts, bacteria, hot stream and so on in raw water, and then using the Ozone device to guarantee the finished water quality standards.

The system is set up automatic and manual modes. Custom programmed system uses conventional relay as the central control device, through the multi-point multi-way  level sensor, dynamic pressure controller combinations to achieve the automatic mode. Manual mode can be used to installation and maintenance the failure which the automatic mode can not work.

 Under normal circumstances, the system can be placed in automatic operation mode of the work of continuous operation, it will automaticly monitor water quality, operation simple, stable, safe and reliable.

Q:How to judge the quality of the water purifier is very important
Modern water purifier in addition to activated carbon, often there are membrane components and other materials, together to form a water purifier, to eliminate the above-mentioned shortcomings of activated carbon. The pore size of microfiltration, ultrafiltration, nanofiltration and reverse osmosis are four 0.1-10 m, 0.005-0.1 mu m, 001-0.008 mu m and 0.0005-0.002 mu m respectively. So from the interception and removal of impurities in the water effect, reverse osmosis membrane water purification effect is the best, it can remove almost all harmful impurities including various inorganic and organic compounds, such as carcinogenicity, mutagenicity and mutation of chemicals, algae toxins, bacteria, viruses, algae, and heat source and so on, and these are other water purifier can not meet all the.
Q:Is the water filter air cleaner better than the filter screen?
The additional functions of the purifier include humidifying, negative oxygen ion, etc.Humidification is divided into ultrasonic humidification and non fog humidification (also known as air conditioning humidification) two kinds. Ultrasonic humidification is the use of acoustic shocks, so that the water molecules are separated into a few micron particles, emitted into the air. No fog humidification is allow water evaporation, emitted into the air. Because it is natural evaporation, water molecules become gaseous, so invisible. In terms of the human body, no fog humidification is much better than ultrasonic humidifying comfortable.The function of negative oxygen ions in the air purifier is installed an electronic negative ion generator, in order to increase the air in the negative oxygen ion content. This technology is now mature, the cost is low. But the negative oxygen ion artificial electricity generated, far from negative oxygen ions generated and comfortable to human nature good.
Q:Can household water purifier purify water really?
Yes, it is.. Good water purifier, with ultrafiltration, the filter diameter will be smaller than the diameter of bacteria... General E. coli.. Will filter, but the premise is filtered quality to pass, can not have silk leakage phenomenon... The addition of active carbon also improves the taste,.
Q:What are the major differences between backwash filters and self-cleaning filters?
Backwashing filter and fully automatic backwash filter1. stainless steel filter screen, ordinary backwashing filter, butterfly valve with manual butterfly valve, automatic backwashing filter, electric butterfly valve,
Q:How does the tap filter and enter the water tower?
The first step is to install the water tower filter first. The utility model relates to a water tower filter, which is an improved water tower filtering device, mainly comprising a filter cylinder, wherein the top end of the filter cylinder is provided with an opening, and the bottom end is provided with a sealing surface, and the sealing surface is provided with a plurality of through holes
Q:How about bottled water or filtered water?
You can drink some kind of large filter water, but do not rely on the water, no matter what kind of filtering, filtering and processing of all minerals, only water, I have seen them made experiments with two electrode bars, if there is no pure water, mineral elements, filter out of the water is very clean. But at the same time, we also should think of, water is water. I hope I can help you.
Q:What's the name of the filter installed in the water pipe during the decoration?
As far as filtration performance is concerned. The pre filters are now in circulation on the market, in addition to a single stainless steel filter has many accidents, such as softening pre filter: the use of resin or phosphate crystal silicon as carrier, calcium and magnesium ions by ion exchange in the form of removal of high content. In order to solve the scale problem! In addition, the particle carbon pre filter: the use of carbon adsorption characteristics of the adsorption of water, such as color, odor, and residual chlorine, such as sense of the carrier of harmful pathogens! Of course, there are many pre market is to filter stainless steel mesh and softening, filtration or adsorption filter together! This type of mixing filter is generally necessary only under certain water quality conditions!
Q:Do you eat purified water for a long time?
Purification of water compared to the outside of the water, there is a problem only in domestic disputes is the impact of water pH and mineral electrolyte on the human body, which is completely diet supplement, so unless you are very picky about food, or use pure water for a lifetime will not affect the diet instead of health and safety.Eat more fruits and vegetables Oh!
Q:About the choice of fish filter!
The flow of the filter to achieve the water more than 6 times before, you are full of water is 45 liters, so the flow of the filter to 300 liters, taking into account the position you put little mug, while the cashier but also beautiful, so large filter or filter cartridge is not suitable, as recommended by the waterfall filter, but the filtration capacity of individual biochemical waterfalls is too weak, so it is necessary to add a water Sprite, which can strengthen the cultivation of nitrifying bacteria, biological filtration, nitrifying bacteria survive, water will be clear, otherwise your power filter again, the water is muddy. But Water Goblins need to be fitted with separate oxygen pumps to work properly.
Q:Can the drinking water filters sold in the market achieve the purpose of filtration?
4, reverse osmosis: filter pore size of 0.0001-0.001 microns, typical applications such as reverse osmosis membrane, can filter out ions, basically only water molecules through, but need energy consumption, waste water more;The drinking fountains sold on the market are generally ultra - filtration machines, reverse osmosis machines, ceramic machines, each with its own characteristics, can be purchased according to their own needs:1, the whole house water purification: it is recommended to buy ultra filter machine, low cost, no energy consumption, long service life, purification capacity, after the activated carbon, you can drink straight;2, straight drink: it is recommended to use reverse osmosis machine, but the need for electricity pressure, waste water accounted for 7.
