The results show that proper control of additive, flocculating agent, temperature, stir speed, quantity of each agent and other process parameters could effectively remove the impurities in the coagulation bath such as the solid, big molecules in the forms of undissolved colloid and semi-colloid. The sizes of flocculates are big and loose, ready to precipitate, therefore the impurity removing effect is very ideal, greatly improving the exchange ability of the ion exchange resin in the subsequent process.
