Baidu look for is actually a blank in this regard, may possibly I request the beloved close friend to counsel.

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

1, the conventional swimming pool drinking water filtering generally will likely be specialized equipment, the therapy method is: pool area backwater - locks concentrator - flocculant dosing - multi-multimedia filtering (deep removal of harmful particles) - sterilization program - heating System (adapt water temperature) - pool normal water.

There is also a little swimming pool area, that is straight applyed to the pool area to deal with the disinfectant.

2, 3 Pool area water sterilization generally involves three sorts: salt hypochlorite (prescription drug); chlorine dioxide (power generator); ozone (power generator)

The initial two are sterilized by successful chlorine. The successful chlorine articles in water can achieve 2~5ppm. The sterilization result will last for a long time, nevertheless it will generate odor (think of the taste of disinfectant water).

Ozone gear is more pricey compared to the first couple of, and robust oxidizing qualities make your getting rid of of microorganisms 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 domestic substantial-stop swimming pool h2o treatment methods are ozone sterilization, and also the overseas competitors swimming pools will also be ozone sterilization.

4. In the end, the water therapy broker is actually a medicine, which is not good 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 response. I came across it for you personally. There are actually a lot of words. I can't copy it once and copy it separately.

10. What is residual chlorine? Why should the pool manage residual chlorine?

The so-called recurring chlorine refers to the totally free chlorine remaining within the water following the chlorine-that contains anti-bacterial is applied inside the pool. It indicates that the program amount is sufficient get rid of the microorganisms along with the malware and then there continues to be staying, which could guarantee the disinfection effect of the h2o entire body. .4~.6mg/L,

The recurring chlorine crawl makes it necessary that this type of water physique should invariably be properly disinfected without stench.

11. What aspects will change the disinfection result of the pool area?

Aspects affecting the disinfection outcome of your swimming pool area include: the choice of anti-bacterial, the amount, the approach useful, the get in touch with duration of the disinfectant with water, and stuff like that.

12. Why does this type of water sometimes change colour once the swimming pool is defined into disinfectant?

Such a thing happens generally once the initial treatment or right after the rain. 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 in the bottom from the pool is taken away with a committed pool suction power machine.

Disinfection: Put disinfectant to get rid of viruses, bacteria and algae and so on. in the water.

Moving filtering: The treated drinking water is motivated by way of a device equipped with quartz fine sand, turned on carbon dioxide or some other special filtering materials to intercept recurring harmful particles in the water to help cleanse this type of water.

Usually, the liquid therapy and application techniques for private pools are as follows:

1) Stop and prevent moss progress

Position copper sulphate in an amount of 2~3Kg for each 1000m3 water, and placed it 1~2 instances on a monthly basis (or apply it when insects or moss are normally found).

Copper sulphate, also known as alum, is definitely an algicidal drug. This is a blue asymmetric triclinic crystal or natural powder, simple to dissolve and drinking water. It may kill and resist microbial growth, and may adjust the swimming pool h2o to seawater azure.

Soon after two hours of copper sulfate is applied, the following surgical procedures are performed:

2) Change the pH (pH), there are two types of pH adjustment medicines:

Sodium carbonate (soft drink), white colored natural powder or great debris, easily soluble in normal water, alkaline, employed once the pH is very low, the pH worth is elevated by 1 degree, 15g of 1m3 normal water.

Hydrochloric acidity, robust acidity, as soon as the pH gets to 8.2 or maybe more, it can be placed at 5~10Kg per 1000m3.

When the pH from the pool area h2o is 7.5.~8., it is ideal.

3) Sterilization and disinfection (see information).

4) Precipitation

It really is applied in a dose of 1000 m35 to 10 Kg utilizing polyaluminum chloride (PAC). Right after the relieve, the blood flow system is established for around 30 minutes, in order that the snow shows up in water, in fact it is continue to 6 to 8 time, and it is becoming vacuumed.

5) Vacuum-cleaning

After the previously mentioned procedure is finished, cleaning is conducted.

Note: When executing methods 1~3, the blood flow process ought to be turned on to consistently disperse the agent in the water. Try to make it uniform if there is no circulation system.

3. What is coagulation, coagulation and coagulation?

Many of the debris in the water are badly charged. Because of the same sex, they are difficult to bond together to become larger particles. Only a substantial amount of favorably billed coagulant is put in to the normal water to help make the colloids coalesce. Named cohesion.

A linear construction of any cement (for example polyaluminum chloride) is unveiled to the normal water, one area of the wire draws a colloidal particle, along with the other colloidal particle works as a connecting link in between the two dust that happen to be considerably separate. The procedure of generating the particles slowly larger sized and transforming into a sizeable particle floc (commonly known as silk blossom) is referred to as flocculation.

Coagulation and flocculation are collectively known as coagulation.

The so-known as coagulation method refers back to the procedure for mixing chemicals to the water throughout the normal water treatment method approach, mixing up water and substances, and causing coagulation and flocculation of other colloidal elements within the water.

Coagulation remedy means the procedure of normal water treatment method after incorporating the representative in normal water, the formation of colloids and adsorption with other colloidal contaminants in the water, flocculation into sizeable contaminants, and ultimately sedimentation.

4. What is a coagulant? What coagulants are commonly employed?

In water therapy, a product competent at binding and agglomerating colloidal dust in water is named a coagulant.

1), alum: white colored strong, also known as potassium, light weight aluminum bismuth, is actually a dual sodium of aluminium sulfate, potassium sulphate, the main aspect of AL2O3 content material ten percent, as a obstruct, dissolved in normal water to hydrolyze to form lightweight aluminum hydroxide Precipitate, the quantity of which is 20~25Kg/1000m3 h2o, suited to PH value 6~8, on account of bad effect and acidity, it is hardly ever useful for drinking water treatment.

2) Polyaluminum chloride (PAC): It is really an inorganic polymer. The main part AL2O3 information 30% 1 is actually a colorless or yellow resin granular solid, and the option is a colorless or yellow-colored brownish obvious liquid. Sometimes it is black color on account of impurities. The content of lightweight aluminum chloride within the sound item is 20Per cent to 40Per cent, the content of standard aluminum chloride is approximately 20Per cent, as well as the content material of yellowish polyaluminum chloride is >30Percent. Liquid product that contains aluminum chloride

About 8Per cent.

Polyaluminum chloride adjusts to pH 7~8. Polyaluminum chloride is blended with physicochemical operations such as precipitation, coagulation and adsorption through the hydrolysis process, that may remove suspended solids, eliminate steel, get rid of cadmium, take away fluorine, eliminate radioactive contamination, and take away floating things. The impact is much more than 5 occasions that relating to alum. At the moment, the most prevalent use of this drug, the general amount is five to ten grams per m3 water.

3) Aluminum sulfate: The principle part of AL2O3 is 15%, which is as substantial or granular. 9. What sorts of disinfectants are employed in private pools?

The disinfectants currently utilized in private pools are bleaching natural powder, bleaching drinking water (sodium hypochlorite), water chlorine, and trichloroisocyanuric acid (TCCA).

1) Bleaching powder: It is a mixture of sodium hypochlorite, calcium supplement chloride and calcium mineral hydroxide, which is actually a white-colored to off of-white colored powder or granule. It provides impressive chlorine stench, is very volatile in general, has robust hygroscopicity, is readily decomposed by the act of normal water, light and heat, and might also interact with Carbon dioxide inside the air flow. The aqueous solution is alkaline, the aqueous solution releases an effective chlorine component, which has bleaching, sterilization and oxidation effects, but has sediment, and the surface of the water has a layer of white floating matter, which is irritating to the gastrointestinal mucosa, respiratory tract and skin, and causes cough and affects vision. .

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

2) Drifting normal water (salt hypochlorite): It is actually equipped by transferring chlorine petrol into the caustic soda pop solution. Its successful chlorine content is higher than (similar to) ten percent (nationwide normal), along with the remaining 90Per cent is salt drinking water. This is a colorless or gentle greenish yellowish water. It may be miscible with drinking water in a limitless amount. Generally, the successful chlorine articles of business normal water rinsing is not really less than the federal standard.

The bleaching drinking water is alkaline. If it experiences heating, encounters lighting, encounters lowering substances, and it is easily decomposed and decomposed by organic and natural matter, paa polymer it is a risky oxidant. It can be rapidly decomposed into sodium chloride, sodium chlorate and air beneath photosynthesis. Salt hypochlorite If the PH worth in normal water is greater than 6.5, it begins to be ionized and decomposed into a substantial amount 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, in recent times, the introduction of trichloroisocyanuric acidity (TCCA) has gradually replaced bleaching.

3) Trichloroisocyanuric acid (TCCA)

Trichloroisocyanuric acid solution (TCCA), also called solid chloric acid, white colored crystalline powder, also highly processed into granular, flake, is undoubtedly an organochlorine anti-bacterial, challenging to break down, saved in a dry atmosphere for 1 12 months, its effective chlorine information only Reduced by 1%, almost all the procedure for hydrolysis of trichloroisocyanuric acid (TCCA) is available by means of hypochlorous acidity, and that is a powerful oxidant, which can oxidize and degrade the proteins of the pathogenic bacteria, as the hypochlorous acid solution molecule is tiny. According to the measurement, at the same concentration, strong penetrating power, therefore, its bactericidal effect is high,

The bactericidal power is 80~100 instances stronger compared to drifting drinking water.

In addition, TCCA features a very long-enduring effect, and features the effect of disinfecting o2, increasing the fresh air content material in h2o, and precipitating and dissolving right after watering.

The dose is 323g 3rd generation every m.

4) Liquid chlorine

Liquid chlorine is really a dangerous and dangerous gasoline. It takes unique professionals and equipment for storage, transportation and use. It is easy to cause personalized security accidents when working with this medicine, and chlorine gasoline is simple to drop pollution, liquid and smell. The surroundings, the swimming pool area is almost never applied.
