A moderate rate of foam production would be fine. There are many fine homogeneous particles in the tank, can stabilize the foam layer, with activated carbon mat to remove surface active substances. Or make the bubble unstable according to overworry, these are all reasonable countermeasures; Other strategies should also be used to reduce the amount of surface-active substances introduced. The introduction of organic matter can make the electroplating process speed drop sharply. Although the secret recipe of organic chemistry is beneficial to the high accumulation rate, the thickness of the coating can not meet the requirements after the organic matter is brought in, so the activated carbon can be used to solve the tank.
