it adopted the "Proposal".
(4) Use of anti-rust, the value allowed to 1,000 ppm.
(5) When the water quality does not comply with the above table, it is necessary to
add water treatment equipment, to ensure that unit can operate normally.
According to relevant information: water PH <6.5, hardness of <50mg / L, have a
corrosive effect on copper; carbon dioxide> 50mg / L, high solubility and hardness of
groundwater will canker copper. Therefore, recommends that customers should pay
attention to water quality standards
