Whats the difference if your degassing before and slightly increasing PH before entry, or just dropping it in the sump or tank with a high oxygen, high PH ?


Marc.

Actually there is a big difference. De-gassing raises the pH of the solution you are de-gassing. Raising the pH of the effluent solution will decrease the solubility of the Calcium and Carbonate ions down to the same solubility as in your tankwater, so most of the CaCO3 you have dissolved in the reactor will promptly precipitate out. Waiting to mix it with tank water and then de-gassing this mixture will result in a lot less precipitation, because the effluent has been diluted by tank water, and the concentration product of Calcium and Carbonate ions will be a lot less than in the straight effluent, so less will precipitate out.
