How to judge the defoamer is the most suitable foam control solutions in landfill leachate? 1. Defoamer should be tested and verified the added volume by small trial test. 2. The amount and the method of addition depends on the foaming capacity of the water on site. Moreover, the wastewater treatment should be a dynamic process of continuous replenishment of new wastewater. 3. The foami...
During high temperature textile dyeing, there are excessive foam problem in many textile mills. In order to get the most suitable defoamer and competitive defoamers, the material and range temperature is necessary! Under the polyester material, the temperature is above 130℃， Please kindly find the typical defoamer RK-83S.
In fermentation industry, including molasses fermentation, alcoholic fermentation, yeast or amino acid production, and other processes, no matter what type material, the excessive foam affect the efficiency and quality of production. Generally , silicone and polyether defoamers provide high efficiently antifoaming performance in fermentation. How to find a suitable defoamer solution in fermentatio...
Excess foam can create a variety of challenges, all detrimental to pulp processing, paper making white water, sizing&coating: increased maintenance costs, lost capacity, reduced efficiency and longer processing time. Pulp preparation or pulp washing is one of the main process which forms foaming in paper making industry.Anionic surfactants are formed by chemical reaction between alkali an...
Paper making process is an important process for paper forming. A lot of additives, such as sizing agent, retention agent, filter aid,wet strength agent,dry strength agent etc are to be used to form paper with certain performance. These additives are added in different dosing points. And it’s easy to form foaming during white water circulation in closed system. Silicone defoamer, fatty alcoho...
Conversion processes from bauxite to alumina in a Bayer process undergo in a highly alkaline environment. Such extreme pH levels required specific chemistry to be able to function well in a Bayer process. Whether it's for faster red mud settling in the settlers & washers, higher solid content in classifying thickener underflow, or protecting your digester from corrosion during acid cleaning, a...
Antifoam is a type of chemical additive used in the pulp and paper industry to reduce foam formation during the pulping process. It is typically added to the pulp slurry prior to entering the stock chest or paper machine. Antifoam works by forming a thin film on the surface of bubbles, which reduces their surface tension and prevents them from coalescing into larger foam bubbles. This helps mainta...
Antifoam is a chemical compound used to reduce foam in papermaking white water. It is typically added to the wet end of the papermaking process, where it helps to prevent foam from forming and interfering with the production process. According to the different requirements and conditions, fatty alcohol antifoams and polyether defoamers are most acceptable in paper mills. They have their own ...
