We are in a coastal area where the sewage pipelines have leaks; at present, the amount of water flowing in is low while the amount leaking out is relatively high. Is it possible to cultivate bacteria quickly at this salinity level?
There’s no problem; bacteria can survive as long as the salt content is below 1.2%. This won’t have a significant impact on bacterial growth, though the growth rate will be somewhat slower； Moreover, aerobic activity will increase, foam formation will increase, and the removal efficiency will decline.
1% is 10,000 PPM; it’s very difficult and will take a long time. It can only be increased gradually from low concentrations to cultivate more salt-tolerant bacteria.
