Baidu research can be a empty in this connection, could I check with the beloved good friend to counsel.

According to the regulations, the pool water should be continuously cycled for 24 hours, and the adult pool cycle period is 6h.

1, the formal pool water filtration usually will be committed gear, the remedy method is: pool backwater - hair concentrator - flocculant dosing - multi-multimedia filter (serious removing of toxins) - sterilization system - heating System (adapt water temperature) - pool area normal water.

There is also a small pool area, which is directly poured in to the swimming pool to take care of the disinfectant.

2, 3 Pool h2o sterilization normally requires about three types: sodium hypochlorite (pharmaceutical); chlorine dioxide (electrical generator); ozone (power generator)

The first two are typical sterilized by efficient chlorine. The successful chlorine content in the water can attain 2~5ppm. The sterilization effect lasts for a long time, nevertheless it will generate smell (think about the style of anti-bacterial water).

Ozone tools are more expensive than the first couple of, and strong oxidizing attributes create the hurting of germs quick. At the same time, the decomposition is fast, and it will become oxygen after about 15 minutes, which is good for the water body, has no effect on the human body, but has no continuous sterilization effect.

Currently, the household substantial-end swimming pool h2o treatment is ozone sterilization, as well as the overseas rivalry swimming pools can also be ozone sterilization.

4. After all, the water remedy agent is a medicine, which is not great for your body. If it is still better after the equipment is added, if you directly add it to the swimming pool, you should master the dosage.

Sorry, it's not my respond to. I found it for yourself. You can find lots of terms. I can't copy it once and copy it separately.

10. What is recurring chlorine? Why would the swimming pool handle residual chlorine?

The so-referred to as left over chlorine refers to the totally free chlorine leftover in water following the chlorine-that contains anti-bacterial is applied in the swimming pool. It indicates the program volume is enough to get rid of the germs as well as the malware and there remains to be leftover, which may ensure that the disinfection effect of your h2o body. .4~.6mg/L,

The left over chlorine index makes it necessary that the water physique should invariably be successfully disinfected with out odour.

11. What factors will modify the disinfection impact of your swimming pool?

Elements influencing the disinfection outcome from the swimming pool area consist of: deciding on a anti-bacterial, the total amount, the technique useful, the contact period of the anti-bacterial with drinking water, and so on.

12. Why does water sometimes modify shade once the pool area is defined into disinfectant?

This occurs mainly following the first remedy or right after the rainfall. The main reason is that there is too much organic matter in the source water, because these organic substances are oxidatively denatured to produce color after the disinfectant, and these colors can be removed by coagulation. Suction pool area: The sediment sinking at the bottom of the pool area is taken away by way of a specialized pool suction power device.

Disinfection: Add more disinfectant to kill viruses, algae and bacteria etc. in the water.

Moving filtration: The taken care of normal water is pumped through a system equipped with quartz fine sand, turned on co2 or some other specific filtering supplies to intercept residual pollutants in the water to increase detoxify the water.

Usually, this type of water treatment and app methods for swimming pools are highlighted below:

1) Stop and prevent moss growth

Place copper sulphate in an accumulation 2~3Kg every 1000m3 of water, and put it 1~2 occasions monthly (or utilize it when pests or moss are normally found).

Copper sulphate, also called alum, is definitely an algicidal medication. It really is a glowing blue asymmetric triclinic crystal or natural powder, an easy task to melt and water. It might resist and kill microbial growth, and can change the pool water to seawater light blue.

Right after two hours of copper sulfate is used, the subsequent procedures are carried out:

2) Adjust the pH (pH), the two main kinds of pH modification prescription drugs:

Sodium carbonate (soda pop), white colored natural powder or good contaminants, webpage quickly soluble in normal water, alkaline, utilized if the pH is very low, the pH importance is greater by 1 degree, 15g of 1m3 h2o.

Hydrochloric acid, powerful level of acidity, if the pH gets to 8.2 or even more, it could be located at 5~10Kg every 1000m3.

Once the pH of the swimming pool drinking water is 7.5.~8., it can be suitable.

3) Sterilization and disinfection (see particulars).

4) Precipitation

It is employed at a dose of 1000 m35 to 10 Kg employing polyaluminum chloride (PAC). After the launch, the circulation product is launched for 30 minutes, in order that the snow shows up within the water, in fact it is continue to 6 to 8 hours, and is also becoming vacuumed.

5) Vacuum-cleaning

Once the above process is completed, cleaning is performed.

Notice: When executing actions 1~3, the flow method should be excited to consistently disperse the representative in water. If there is no circulation system, try to make it uniform.

3. What is coagulation, coagulation and coagulation?

Many of the dust in water are badly billed. They are difficult to bond together to become larger particles, because of the same sex. Only a large amount of positively billed coagulant is defined in the normal water to create the colloids coalesce. Known as cohesion.

A linear framework of any cement (for example polyaluminum chloride) is introduced into the normal water, a single portion of the wire pulls a colloidal particle, and also the other colloidal particle provides a bonding fill between your two contaminants that happen to be far away from each other. The entire process of producing the particles steadily greater and transforming into a sizeable particle floc (popularly known as silk blossom) is referred to as flocculation.

Coagulation and flocculation are collectively termed as coagulation.

The so-called coagulation method signifies the process of mixing chemical substances in the water through the h2o treatment method process, combining drinking water and chemicals, and triggering coagulation and flocculation of other colloidal materials within the water.

Coagulation remedy signifies the procedure of water treatment soon after the addition of the agent in water, the formation of colloids and adsorption along with other colloidal dust within the water, flocculation into sizeable debris, and finally sedimentation.

4. What exactly is a coagulant? What coagulants are commonly utilized?

In normal water remedy, a product effective at binding and agglomerating colloidal dust in normal water is known as coagulant.

1), alum: bright white strong, often known as potassium, lightweight aluminum bismuth, is truly a increase sea salt of aluminium sulfate, potassium sulphate, the primary element of AL2O3 articles 10%, in the form of a prevent, dissolved in drinking water to hydrolyze to form aluminium hydroxide Precipitate, the amount of that is 20~25Kg/1000m3 normal water, appropriate for PH value 6~8, because of bad acidity and effect, it is rarely utilized for h2o therapy.

2) Polyaluminum chloride (PAC): It is an inorganic polymer. The primary aspect AL2O3 content 30Per cent 1 is a colorless or yellow-colored resin granular reliable, and the solution is a colorless or yellow brown translucent liquid. It is sometimes black color as a result of harmful particles. This content of aluminum chloride within the reliable product is 20% to 40Percent, the material of standard aluminium chloride is around 20Per cent, along with the content of discolored polyaluminum chloride is >30Percent. Liquefied product that contains light weight aluminum chloride

About 8Percent.

Polyaluminum chloride adapts to pH 7~8. Polyaluminum chloride is blended with physicochemical operations like precipitation, adsorption and coagulation in the hydrolysis approach, that may eliminate stopped solids, get rid of metal, take away cadmium, get rid of fluorine, take away radioactive air pollution, and take off drifting physical objects. The outcome is a lot more than 5 periods that relating to alum. Currently, the most typical utilization of this drug, the overall dose is 5 to 10 gr per m3 of water.

3) Lightweight aluminum sulfate: The principle part of AL2O3 is 15Per cent, which is such as enormous or granular. 9. What sorts of disinfectants are currently used in pools?

The disinfectants presently used in swimming pools are bleaching natural powder, bleaching normal water (sodium hypochlorite), liquid chlorine, and trichloroisocyanuric acidity (TCCA).

1) Bleaching natural powder: It is actually a mix of sodium hypochlorite, calcium supplement chloride and calcium mineral hydroxide, which is a white-colored to off-white powder or granule. It provides remarkable chlorine odor, is extremely unstable in nature, has strong hygroscopicity, is easily decomposed by the act of h2o, heat and light, and might also interact with CO2 in the air flow. Has sediment, and the surface of the water has a layer of white floating matter, which is irritating to the gastrointestinal mucosa, respiratory skin and tract, and causes cough and affects vision, although the aqueous solution is alkaline, the aqueous solution releases an effective chlorine component, which has oxidation, bleaching and sterilization effects. .

Medication dosage: about 20~30Kg for every 1000m3.

2) Drifting h2o (salt hypochlorite): It really is ready by transferring chlorine petrol in to the caustic soda answer. Its powerful chlorine content is greater than (equivalent to) ten percent (countrywide standard), and also the outstanding 90Percent is sodium drinking water. It is actually a colorless or lighting greenish yellow-colored water. It can be miscible with normal water in a infinite proportion. Generally, the powerful chlorine information of professional drinking water rinsing is just not under the nationwide common.

The bleaching water is alkaline. When it experiences heat, encounters lighting, encounters lowering compounds, and is also quickly decomposed and decomposed by organic matter, it is actually a dangerous oxidant. It is actually rapidly decomposed into salt chloride, sodium chlorate and oxygen under photosynthesis. Salt hypochlorite When the PH importance in water is higher than 6.5, it begins to be ionized and decomposed into a lot of Na (salt ion) and CIO_ (hypochlorite). Under alkaline environment, the hypochlorite killing effect is very poor, only 1% of hypochlorous acid, obviously if Stabilizing hypochlorous acid, so that it can not be dissociated into hypochlorite, the bactericidal effect can be increased by 99 times.

Consequently, recently, the development of trichloroisocyanuric acid (TCCA) has gradually exchanged bleaching.

3) Trichloroisocyanuric acid (TCCA)

Trichloroisocyanuric acid (TCCA), also known as strong chloric acidity, white colored crystalline powder, also highly processed into granular, flake, is surely an organochlorine anti-bacterial, difficult to decompose, kept in a free of moisture environment for 1 calendar year, its efficient chlorine content only Lessened by 1Per cent, almost all of the technique of hydrolysis of trichloroisocyanuric acidity (TCCA) is out there such as hypochlorous acid, which is actually a powerful oxidant, which may oxidize and degrade the protein of your pathogenic bacteria, for the reason that hypochlorous acidity molecule is small. Strong penetrating power, therefore, its bactericidal effect is high, according to the measurement, at the same concentration,

The bactericidal potential is 80~100 periods stronger in comparison to the drifting normal water.

Additionally, TCCA features a long-enduring outcome, and contains the effect of disinfecting oxygen, improving the fresh air content material in water, and precipitating and dissolving following irrigating.

The dosage is 323g 3rd generation for every m.

4) Fluid chlorine

Fluid chlorine is really a dangerous and dangerous gas. It will require special professionals and equipment for transportation, storage and use. You can actually result in personalized protection mishaps when working with this treatments, and chlorine gas is not hard to get rid of liquid, smell and pollution. Environmental surroundings, the pool area is almost never applied.
