The pH value of the water purified by the acidic water treatment system is low, around 6 only, while the ammonia nitrogen content is high. Please analyze the possible reasons and suggest corrective measures. Adding alkali had little effect.
During the stripping process, sufficient amounts of hydrogen sulfide and ammonia are removed; however, acidic carbon dioxide is not completely removed, resulting in a slightly acidic condition, which should be within the normal range.
