Swimming pools are one of the services that bring a lot of profit to the tourism and resort industry. Poor swimming pool water quality will cause many negative consequences such as: affecting human health, high operating costs, excessive bacterial growth,… Treating and clarifying swimming pool water will bring to many benefits:
Restrain the overgrowth of bacteria: Infected swimming pool water will be an ideal environment for bacteria to multiply. Bacteria cause lake water to change color, make the water cloudy, unsightly, and cause moss and algae to grow, affecting health and increasing operating costs.
Maintain equipment durability: Swimming pools always contain an amount of chemicals that help balance the pH level in the pool. A swimming pool with good water quality will help the equipment in the pool maintain better durability, avoid reducing its lifespan and deteriorating quickly.
Protect users’ health: Contact with polluted water sources will affect users’ health. They are the cause of mold, skin diseases and many other pathogens. Swimming pool water has stable quality to help protect human health.
Pool water of stable quality helps protect human health, limiting the risk of skin and eye diseases
Swimming pool water is cloudy and discolored due to a lot of suspended dirt of very small size that cannot be filtered in the usual way or is destroyed by oxidation. Therefore, to clarify swimming pool water, people often use specialized chemicals for swimming pools to balance pH, sedimentation, disinfection, etc. Accompanied by regular pH measurement activities. browse and use filtering tools. Specifically how to do it below
The standard pH level in swimming pool water is 7.2 – 7.6. Then the water has clarity that is easy to maintain, helping to save on tank water maintenance chemicals. The success or failure of the water treatment process depends on the pH balance in the water.
The pH level in tank water is too low: Domestic equipment is easily corroded, causing the filter to be less effective when operating. Besides, they cause users to have skin irritation and eye irritation when swimming.
The pH in the tank water is too high. The water is easily cloudy and has a lot of suspended dirt. Water is heavy and makes the water treatment process more laborious, costly, and less effective.
For the water clarification process to be effective, test the pH and chlorine levels before using chemicals in the pool for appropriate treatment. Use phenol, OTO to test. Take a water sample at a depth of 40cm above the lake surface into a test tube, add 2-3 drops of phenol into the tube to test pH, 2-3 drops of OTO into the tube if testing chlorine. Close the lid and shake well then see the results.
For the water clarification process to be effective, test the pH and chlorine levels before using chemicals in the pool for appropriate treatment.
Depending on the condition of the swimming pool, use chemicals in appropriate dosages. In general, the market is divided into 4 groups of chemicals according to their intended use as follows:
Chemical group used to disinfect water: Chlorine tablets (TCCA), chlorine powder,…
pH balancing chemical group: NaOH, pH-, pH, Soda ash,…
Group of water clarifying and sedimentation aid chemicals: PAM, PAC, powdered flocculants, flocoulants,…
Chemical group that inhibits and destroys moss and algae: Hydrated copper, powdered copper (CuSO4)
Chemicals used to disinfect water are used when swimming pool water is infected by leaves, dirt or people during use. Contaminated water creates conditions for bacteria to multiply, causing mold, fungus, and many other diseases. Then you can use chlorine to maintain a balance of chlorine levels in the water, preventing bacteria from growing and algae from spreading.
How to use: When the tank is in a regular state of operation, use a daily maintenance dose of 2g – 3g/ 1m3 of tank. For small-sized swimming pools that are rarely used, such as rarely used family swimming pools, the dosage can be reduced and treated annually. Increase the dose with public swimming pools.
Chlorine is used to maintain a balanced chlorine concentration in water, preventing bacteria from growing and algae from spreading.
After measuring the pH concentration, you can add pH+ or pH- to maintain the pH balance of the pool:
Increase pH: Use HCl acid or pH+ chemicals in fixed doses. About 1kg per 100m3 of water can increase the pH by 0.2. Depending on the current water pH, adjust the dosage.
Reduce pH: Use NaOH or pH- chemicals to adjust. About 1kg per 100m3 of water can reduce the pH by 0.1.
Note: If you need to process a large amount, divide it into small portions several times so that the lake water does not shock and cause counterproductive effects. In case you have a balance tank, you can put chemicals directly into the tank for the filtration system. When the amount of acid is reduced and the pH is neutral, it can be used. The tank needs to stop operating for at least 6 hours after treatment to ensure user safety
Use Soda ash to balance the pH in the pool
To kill moss and algae, chemicals such as CuSO4 (copper sulfate), Chlorine,… are popular choices today. They help inhibit the rapid spread of algae, effectively kill algae and maintain clear water for the pool.
How to use: Use 1 liter of CuSO4 (copper sulfate) for about 10m3 of water per month. With chlorine, use a dose of 3.5 – 4.5kg / 100m3 to kill algae. Note that algaecides will react immediately with chlorine in the water, so you need to pour them right in front of the outlet for best results.
The process of settling and clarifying swimming pool water is carried out after balancing the chlorine and pH levels in the pool. This process helps remove impurities and dirt suspended in water. Currently, PAC is the most commonly used chemical. With a mechanism to coagulate dirt faster than conventional sedimentation aid chemicals, does not suddenly reduce pH, large flocs settle easily and does not require support tools, PAC is the superior solution used by many people. picker.
Making:
Turn off the water filtration system and return the water surface to a static state
Mix a small amount of PAC into water, then spread it around the lake surface. PAC can be dissolved in any ratio, but the recommended dosage is about 2kg per 100m3 of water at a time.
After 6 hours, when the chemicals have completely dissolved in water and the dirt has flocculated with a settling film, use specialized swimming pool cleaning equipment like racquets or cleaning robots to handle floss.
With a mechanism to coagulate dirt faster than conventional sedimentation aid chemicals, PAC chemicals are a superior option chosen by many people.
After being treated with chemicals, swimming pool water needs to be filtered daily with a filtration system to maintain the best condition. There are two popular forms of filtration on the market today: Smart filter and piped filter (including sand filter and pump).
Filtration frequency: every 4 – 8 hours, all water in the swimming pool must be run through the filtration system once. For outdoor tanks, filtration time should not exceed 4 hours/time. For shallow tanks, the time is no more than 2 hours/time. The filtration time of an indoor tank can be up to 8 hours/time
In addition to regularly checking the pH and chlorine levels in the pool to determine the condition of the pool, you can observe the color of the pool water to determine water quality. Here are some swimming pool conditions that can be observed through water color and treatment:
If the green swimming pool water contains algae and moss, the main cause may be due to too high pH, not enough moss-killing chemicals, not enough water filtration time, or the pool being overused with a cover. Some ways to clean swimming pool water are as follows:
Lower the pH to 6.8 – 7.2 if the pH is too high
Chlorine the swimming pool at a dose of 10g/m3 of water or 1 liter/10m3 if the moss-killing chemical is not enough.
Turn on the filter continuously until the water color is normal and change the filter bag twice a day to meet the full filtration time.
Vent the tank as much as possible or remove the tank cover if necessary
Note: Algae and moss often cling to the walls, bottom and sides of the tank so it is necessary to clean periodically and regularly to limit their growth. Increase the frequency of tank inspection and cleaning after storms.
Pool water turns green due to moss and algae contamination
The cause of cloudy water comes from chemicals or minerals in the water. Specifically, the causes of cloudy water and how to handle them are as follows:
Chlorine is overused or the pH is too high, leading to cloudy water. You should lower the pH level below 7.2 and wash the swimming pool filter bag at least twice a day
Milky white water due to chlorine overdose combined with algaecide. The solution is to drain 1/2 of the water in the tank, adjust the pH level and run the filter continuously
Water is heavy due to many inorganic salts, causing white sediment to precipitate. A descaling machine can be used in case of excessive sediment. Combine with water softening chemicals at the appropriate dosage.
Water contains too many microorganisms and mineral salts or too much cyanuric acid due to the use of chlorine and not changing the water regularly. The solution is to drain 4/5 of the pool water and replace it with new water with a large filter bag.
The cause of cloudy water comes from chemicals or minerals in the water
The lake water is translucent silver or black mainly due to low pH. If this situation repeats frequently, you need to check the pool filtration system and balance tank. The sand filter may have lost sand and gravel due to rinsing, leading to reduced filtration efficiency. Please replace the filter with a new one.
Reddish brown or black lake water may be due to water containing many metals such as copper, iron, manganese or the tank water supply comes from wells, ponds and lakes. Then use sedimentation aid chemicals to coagulate impurities and heavy metals, then treat the floc with a racket or pool cleaning equipment. Combine with running a pool filter to stabilize the water.
