impact of the regeneration effluent on the environnement
(OP)
we have an ion ion exchanger (mixed bed)which is regenerated simultaneousely with naoh and h2so4. the effluent are directed to a trench of neutralization to adjust pH. this trench is not covered.i want to know the impact of these effluents on the environnement . thanks





RE: impact of the regeneration effluent on the environnement
You have concentrated the impurities that had been in the water into your effluent. So, the output depends upon what was in your water. Do you have a) analysis of the incoming water and b) the number of gallons of water treated prior to regeneration? With these numbers, assuming 100 % removal from the initial water, you can calculate the mass of each constituent in your neutralized effluent. And, from the volume of the effluent created, you get concentrations.
Presuming that your combined effluent streams are neutral, the effect on the environment could be as little as adding salt water or as bad as contaminating the site with toxic metals. There is also the chance of contamination with illegal levels of anions such as cyanide or chromate if you have been treating industrial waste water (instead of creating DI water from tapwater).

In the USA, one of the largest water treatment companies was fined by the EPA for treating hazardous waste without proper permits or secondary containment. They were regenerating ion exchange units, used to produce high purity DI water from tapwater (legal drinking water). Had been doing so for many years. I don't remember which impurity or impurities caused the problem, but they argued the case and lost.
