How to choose between silicone defoamer and polyether defoamer? RISE tells you the best solution
In paper making, pulp, sewage treatment, oil field, power plant desulfurization and other working conditions, foam flooding has always been a headache. Too much foam will overflow the equipment, affect the process precision, reduce the production efficiency, and even cause the problem of substandard environmental protection. Defoamer is the key to solve this problem. But how should we choose the most commonly used silicone defoamers and polyether defoamers on the market at present?
Organic silicon defoamer: the first choice for high cost-effectiveness under conventional working conditions
Organic silicon defoamer is currently the most widely used universal defoamer in the industrial field. Organic silicon defoamer, with their three major advantages of fast defoaming, strong versatility, and cost-effectiveness, have firmly ranked among the mainstream defoamer selection list.
The core advantages of organic silicon defoamer are:
Rapid defoaming speed: Organic silicon defoamer can quickly integrate into the foam system, instantly break the surface foam, quickly suppress foam, solve the problem of foam overflow, and achieve immediate results.
Highly versatile: Organic silicon defoamer is suitable for the vast majority of conventional neutral water quality conditions, without selecting basic water bodies, and have a wide range of adaptability.
Controllable cost and high cost-effectiveness: Organic silicon defoamer has a low unit price, minimal addition, and do not require high investment for daily use, significantly reducing factory costs.
However, one disadvantage of organic silicon defoamers is that they are prone to breaking emulsions in extreme high temperature environments; It is best not to directly use organic silicon defoamer in high demand processes such as fermentation, aerobic biochemical tanks, membrane filtration, and membrane element silicon contamination and blockage.
Polyether defoamer: a silicon free defoamer specifically designed for high-temperature systems
Polyether defoamer belong to silicon free defoamer, which perfectly compensate for the shortcomings of organic silicon defoamer such as high temperature failure and silicon spots. Polyether defoamer is specially designed for complex systems such as high temperature, strong acidity and alkalinity, biological fermentation, membrane treatment, etc.
Core advantages of polyether defoamers:
Excellent stability: Polyether defoamer is heat-resistant, resistant to strong acids and alkalis, and is not easily decomposed or broken under high temperature conditions. Its defoaming effect does not deteriorate in extreme pH environments;
Mild performance: Polyether defoamer belongs to a silicon free formula, which does not inhibit microbial activity. Long term use of biochemical tanks and fermentation tanks does not affect the potency of bacterial strains;
No residue or pollution: Polyether defoamers do not produce silicon spots, do not block ultrafiltration membranes, and have no burden on later extraction, gypsum dehydration, and material separation;
Longer foam suppression time: Polyether defoamers have better sustained foam control ability than organosilicon, reducing the labor cost of frequent addition of chemicals.
However, it is worth noting that the price of polyether defoamers is usually much higher than that of organosilicon defoamers. When used in simple conditions such as normal water treatment and circulating water at room temperature, there may be excess performance, which increases unnecessary drug expenses.
Keep in mind one fact: there is no universal defoamer, it needs to be selected reasonably according to its own process conditions.
