Application Areas

Intelligent Ion Balancing Device
The Intelligent Ion Balance Device (Desalination) is a key component of water quality treatment in cooling water circulation systems. Based on the principle that charged particles migrate to electrode surfaces under the action of an electric field, it enriches dissolved salts and other charged substances in water on the electrode surfaces. By adjusting process parameters to regulate the reaction process and balance the ion concentration in water, it achieves water quality control, reduces carbon emissions, and ultimately realizes water conservation and carbon reduction goals.

Water Treatment Chemicals
1. Circulating Water Treatment Chemicals
1) Cleaning Agents
Remove scale, deposits, corrosion products, microorganisms and other contaminants accumulated in the system to prepare for subsequent pre-filming.
2) Corrosion Inhibitors
Slow down the electrochemical corrosion of metals (e.g., pitting corrosion, crevice corrosion, general corrosion). On the basis of the protective film formed during pre-filming, it maintains long-term corrosion protection effect and extends the service life of equipment and pipelines.
3) Biocides and Algaecides
Alternately dose oxidizing/non-oxidizing biocides and algaecides to prevent the proliferation of bacteria, algae, fungi, biofouling slime and other microbes, and reduce the risk of microbiologically influenced corrosion (MIC).
4) Pre-filming Agents
Form a protective film on metal surfaces to mitigate corrosion, inhibit scaling and prolong the service life of equipment.
5) Scale Inhibitors
Inhibit the deposition of inorganic salts such as CaCO3, CaSO4 and SiO2, and prevent particulate agglomeration. Used in synergy with corrosion inhibitors, it avoids localized corrosion caused by scaling.
6) pH Adjusters
Control the water pH level and maintain the optimal pH range to ensure the efficacious performance of water treatment chemicals such as corrosion inhibitors, scale inhibitors and biocides, as well as prevent equipment corrosion and scaling.
2. Comprehensive Water Resource Treatment Chemicals
1) Ultra-Limit Phosphorus Removal Agent SYS-CP-JX
The effluent phosphorus content meets the Class III standard for surface water (lakes and reservoirs) (TP≤0.05mg/L).
2) Phosphorus Removal Active Factor Agent for Ultra-Purified Water SYS-CP-CJ
Suitable for phosphorus removal in water bodies with extremely low suspended solids (SS≤10mg/L), such as mine sump water and groundwater.
3) Special Agents for Spore Transfer Technology (Spore Agglomerant SYS-BZ-JH, Spore Focusing Agent SYS-BZ-JJ)
Matched for use with spore transfer integrated machines.
4) High-Efficiency Sludge Activator SYS-WJH
Improves the quality and efficiency of biochemical systems in municipal or industrial water treatment plants plagued by activated sludge aging, poor settleability and low water treatment efficiency.
5) Special Fluoride Removal Agent SYS-CF
For the treatment of fluorine-containing water bodies including industrial wastewater, surface water and groundwater.
6) High-Efficiency COD Remover SYS-CCOD
Targeted at refractory COD removal.
7) Heavy Metal Remover SYS-CZJS
