A » Biological fouling in membrane systems, often called biofouling, occurs due to the accumulation of microorganisms, such as bacteria, algae, and fungi, on membrane surfaces. These organisms form biofilms that impede water flow and reduce filtration efficiency. Factors contributing to biofouling include nutrient-rich feed water, inadequate pre-treatment processes, and suboptimal operational conditions, all of which create an environment conducive for microbial growth and biofilm development.

A »Biological fouling in membrane systems is caused by the accumulation of microorganisms, such as bacteria and algae, on the membrane surface. This growth is often facilitated by the presence of nutrients, warm temperatures, and inadequate maintenance, leading to reduced membrane performance and increased maintenance costs.
