colloidal fouling

Colloidal fouling occurs when tiny particles, called colloids, accumulate inside a filter or membrane during water treatment or filtration processes. These colloids are very small, often a few nanometers to micrometers in size, and remain suspended in water due to their charge or size. Over time, they cluster and form a layer on the surface or within the pores of the filter, gradually blocking flow and reducing efficiency. This buildup can lead to increased pressure requirements and maintenance, making it a common challenge in ensuring clean, treated water.
