Its concentration ,is too high, for it to be released into the ,wastewater, system (see figure), so I need to dilute the stream. The easiest thing for me to ,do, is to dilute it with a stream that has water and hydrochloric ,acid, that is coming from another process. The final stream that I release to the ,wastewater, system must be at least 90 mole% water.

How To Lower Chlorine Or Bromine In A Hot Tub (If Too High)

Overly high chlorine or bromine levels can cause issues with your health. Itchy skin, brittle hair, red and irritated eyes, and irritated nasal passages are all signs you have too much sanitizer in your tub. Damage to your tub. High levels of chlorine or bromine will slowly eat away at the soft surfaces in your tub, and may even cause a leak.

dissolved oxygen (DO) will be reduced, the chemical reaction will be accelerated, and biological me-tabolism will be accelerated. If the temperature is too high, the survival of aquatic organisms will be endangered. (Fushun Petroleum Research Institute 1974.) The color of the water is usually directly related to the condition of the water.

High DO can be attributed to the water source and/or dilution due to leaking fixtures or infiltration. Also, if there is a significant amount of dead microbes in the system due to a chemical upset, a high DO may result. The microbes are not robust and are not depleting the oxygen supply.
