Sodium bisulfate - professional pH minus powder
Sodium hydrogen sulfate (also known as sodium bisulfate), with the chemical formula HNaO4S, is an acidic salt. It belongs to the pool treatment products. It is then referred to as pH minus or pH minus powder. It is a derivative of sulfuric acid.
It reduces the pH of water (particularly in swimming pools) and therefore acidifies it. Use it when the pH of your pool or spa exceeds 7.4. It dissolves rapidly and allows a quick return to equilibrium. It is compatible with all pool treatments: chlorine, salt, ozone, bromine, active oxygen...
Its advantage lies in the fact that it is safe for human health once diluted, and biodegradable.
It is available in the form of a yellowish solid powder in 25 kg bags, intended for professionals.
For use with a dosing pump, prefer a liquid pH minus product, based on sulfuric acid. It is available in 26 kg containers, intended for professionals. Also find our pH Plus powder and our liquid pH Plus.
The pH of a swimming pool, spa, or bathing basin should be slightly alkaline. A pH level of 7.4 is recommended. An unbalanced pH impairs water quality and therefore the swimming experience. It also leads to excessive consumption of disinfectant (chlorine, for example). Maintaining the water balance of a swimming pool is an integral part of basin maintenance. It can be affected by air temperature, pool usage, weather conditions, the environment surrounding the pool or spa (vegetation, garden...). Professionals use an electronic pH meter to measure water quality.
Product benefits:
- Concentrated active ingredient formula
- Safe powder formula
- Easy dosage
- Does not generate chloride ions
- Compatible with all treatments, filtration systems, and coatings
MAIN FUNCTIONS
Sodium bisulfate / sodium hydrogen sulfate is used to regulate the pH of water in swimming pools and basins.
INDUSTRIAL USE
Sodium hydrogen sulfate is used for:
- Production of cleaning products
- Production of treatment products for swimming pools and bathing basins
- Industrial water treatment
PROFESSIONAL USE
- Treatment and maintenance of water in swimming pools, spas, ponds, jacuzzis...
- Ecological pesticide in marine environments
- In jewelry: diluted in water for pickling and deoxidizing precious metals after soldering
USAGE INSTRUCTIONS
Application:
Pour pH MINUS - pH MOINS Powder directly into the basin in front of the return inlet(s), with filtration running, or spread over the entire surface of the basin. Pour ONLY in the MANDATORY absence of swimmers.
Avoid direct contact between the coating and the product, as this could damage it. If necessary, pre-dilute the product in a container with warm water.
Dosage:
Allow approximately 75 g of pH MINUS - pH MOINS Powder per 10 m3 of water to reduce the pH by approximately 0.1 units.
Always adjust the pH in several stages, in filtration or recirculation mode, in increments of 0.2 pH units spaced 2 hours apart.
This dosage is calculated for water with standard characteristics. For very different pH or TAC values, the dosage may be doubled or even tripled.
Dosing pump:
pH MINUS - pH MOINS Powder will be injected in solution by a dosing pump. In the dosing pump conditioning tank, dissolve at a ratio of 5 kg of pH Minus pH MOINS Powder in 50–100 liters of water.
The ideal pH value is between 7.0 and 7.4 and should be checked at least once a week. A correct pH value not only preserves the equipment and coating but also ensures the well-being of swimmers and reduces disinfectant consumption.
Recommendations:
Corrosive product. Follow the safety precautions. Use gloves and protective goggles. Store in its original packaging, closed, upright, and protected from frost.
