Membrane contamination is a common challenge in small seawater desalination facilities. It occurs when microorganisms, organic matter, and mineral deposits accumulate on the desalination membranes, reducing their efficiency. This contamination can result from inadequate pre-treatment, fouling, or biofouling, leading to reduced water quality and increased operational costs. Regular maintenance and effective pre-treatment processes, like filtration and chemical dosing, are essential to mitigate membrane fouling. In smaller desalination plants, these issues can be particularly troublesome, underscoring the need for diligent monitoring and proactive measures to ensure the reliable and efficient production of freshwater from seawater sources.
