The most significant factor contributing to membrane fouling in reverse osmosis (RO) systems is the deposition of organic matter, specifically colloids and natural organic matter (NOM), on the membrane surface and within its pores. To understand this, it's crucial to define several key terms. Reverse osmosis is a water purification process that uses pressure to force water molecules through a semi-permeable membrane, leaving behind contaminants. A semi-permeable membrane allows some molecules (like water) to pass through but blocks others (like salts, minerals, and larger organic compounds). Fouling, in this context, refers to the accumulation of substances on the membrane surface or within the membrane pores, reducing its water permeability and overall performance.
