What advantage does membrane treatment have in removing colloidal silica?

Membrane treatment is particularly effective in removing colloidal silica due to its ability to achieve a significant reduction in reactive silica levels, often exceeding 98%. This efficiency is largely attributed to the physical barrier that membranes provide, which allows them to filter out very fine particles, including colloidal substances that might evade other treatment methods.

The high level of performance in silica reduction is crucial for processes that require high purity water, such as in power generation or semiconductor manufacturing. By using membranes, operators can maintain water quality with fewer operational issues and a more consistent output. The specificity of this process in targeting colloids is what makes it a preferred choice when the primary goal is maximizing the reduction of reactive silica.
