Performance and Use
Phosphorus-free antiscalant (inhibitor) MC 700-B does not contain phosphorus. It can greatly reduce sewage treatment costs in areas with strict requirements on phosphorus discharge in sewage. Since it does not contain phosphorus, it reduces the reproduction of microorganisms in the circulating water system and reduces the amount of bactericides, algaecides and slime strippers.

How to Use
(1) Phosphorus-free antiscalant (inhibitor) MC 700-B is used at a concentration of 30 mg/l. It has a good corrosion inhibition effect on water with a total hardness of 100 mg/l and a total alkalinity of 100 mg/l, such as the water in the Yangtze River system. The corrosion rate of carbon steel is less than 0.075 mm/a.
(2) Phosphorus-free antiscalant (inhibitor) MC 700-B is used at a concentration of 30 mg/l. It has a good corrosion inhibition effect on water with a total hardness of 300 mg/l, a total alkalinity of 200 mg/l, and a chloride ion content greater than 300 mg/l. The corrosion rate of carbon steel is less than 0.075 mm/a.
(3) Phosphorus-free antiscalant (inhibitor) MC 700-B is used at a concentration of 60 mg/l. It has a good corrosion inhibition effect on ultra-low hardness water conditions such as the Minjiang River system, with a total hardness of 50 mg/l and a total alkalinity of 50 mg/l.
(4) When using only Phosphorus-free antiscalant (inhibitor) MC 700-B, the optimal concentration is: 40-60 mg/l.
Packaging and storage
Phosphorus-free antiscalant (inhibitor) MC 700-B is packaged in plastic barrels, 25kg per barrel or as determined by the user. The storage period is twelve months.
Safety and protection
Phosphorus-free antiscalant (inhibitor) MC 700-B is acidic. Wear glasses and gloves when operating it to avoid contact with skin and eyes. Rinse with plenty of water after contact.
