The electroplating production process is easy to encounter the problem of foam, and the treatment of electroplating sewage is also a very important part. In the process of sewage treatment, the foam problem will bring many negative effects.
Reasons for foaming of electroplating wastewater:
Electroplating wastewater treatment is prone to encounter foam problems, which are generally caused by the following three reasons.
1. Foam caused by electroplating solution turbidity;
2. Improper use of additives leads to poor surface adhesion and foaming;
3. Poor surface treatment, incomplete surface oil and rust removal, and incomplete removal of oxide film due to excessive organic matter in the bath solution, unclean pre-treatment, high pickling concentration, high impurities in the pickling solution, and the presence of oxide film on the surface of the workpiece before entering the plating bath, all lead to foaming.
The hazards of foaming in electroplating wastewater
If the electroplating sewage foam is not treated in time, it is easy to cause adverse negative effects.
1. Foam affects production, and too much foam will affect production and hinder production progress;
2. Electroplating blistering can affect the rust resistance, cleaning performance, and extreme pressure performance of the product;
3. The oil tank is filled with foam and overflows, which will cause the oil level to drop, damage the components, destroy the uniform supply, and affect the stability of the operation;
4. Electroplating foaming can increase gas-liquid contact, promote oxidation, generate flotation, and cause uneven mixing of components. Affects the quality of the product, causing it to deteriorate or deteriorate;
5. Affects the treatment progress of electroplating wastewater and increases the cost of water treatment.
Use antifoaming agent to eliminate stubborn foam in electroplating wastewater
After decades of development, the comprehensive treatment process of electroplating wastewater has been improved. However, there are still some problems, such as foam. Electroplating sewage foam will affect production, resulting in poor product quality. It will also affect the progress of water treatment. For the foam problem of electroplating sewage, it is a good method to add defoamer for electroplating sewage.
This is to remind all manufacturers that if they encounter the problem of foam in sewage treatment, they can find professional manufacturers to design targeted water treatment defoamers to solve the problem of foam.
