Process Nodes
Key stages of the industry process and the chemicals involved
01
Scale Inhibition & Dispersion
STPP and SHMP chelate calcium and magnesium and disperse particles, controlling fouling on heat exchange surfaces and membrane systems.
02
Alkalinity & pH Control
Caustic soda, pearls and soda ash adjust alkalinity and pH, while TSP combines softening and descaling.
03
Corrosion Inhibition & Carbon Source
Sodium nitrite inhibits corrosion in closed loops; glucose serves as external denitrification carbon source to improve nitrogen removal.

FAQ
Why glucose as denitrification carbon source?
High COD equivalent, fast microbial uptake, no toxic residue and low dosing cost make glucose the common external carbon source for nitrogen removal.
Typical SHMP dosage for scale control?
2-10 mg/L (as product) in circulating systems, adjusted to hardness, cycles of concentration and heat exchange temperature rise.
Do you supply jumbo bags?
Yes. Bulk items like soda ash, salt cake and glucose are available in 500kg/1000kg jumbo bags with bulk delivery options.
Technical support for abnormal water quality?
Yes. We review dosing programs and provide on-site or remote support for scaling, corrosion or carbon dosing anomalies.
