DCH-010 Sodium
thiosulfate
Reagent for removing excess chlorine from water. 9 ml/dm3 of reagent reduces the Cl- content by 1 mg/dm3 10,0 ± 0,5 1,30 ± 0,05
AB-007 Sodium
hydroxide
Strongly alkaline reagent. Used to increase pH of the treated water, acid neutralization and providing the necessary level of alkalinity 1 mg/dm3 of reagent increases alkalinity level by 0.5 mg/dm3 13,5 ± 0,5 1,35 ± 0,05
HAI-727 Hydrochloric
acid
Reagent based on hydrochloric acid which is used for lowering рН and total alkalinity. The dosage of the reagent to be calculated individually for each separate system < 1,0 1,05 ± 0,05
AXI-766 Hydrochloric
acid
Reagent based on concentrated Hydrochloric acid which is used for lowering рН and total alkalinity. Can be used with corrosion inhibitor for system washing. 1,10 ± 0,05
PLP-099 Sodium
bicarbonate
Reagent for lowering рН and total alkalinity 50 mg/dm3 of reagent increases alkalinity level by 30 mg/dm3 > 12,0 (1% soln.) powder
PLM-096 Sodium
hydrosulphate
