Mobar Surface water from wells, rivers or lakes can be contaminated and should be disinfected. This is a simple operation that can be carried out by on-site staff. However, the major drawback with GAC filters is that, with time, the carbon material becomes a breeding ground for bacteria and begins to elute harmful microorganisms into the process water. They need very little maintenance, the only requirement being replacement of the UV lamps every hours, depending on use. Filter disinfection Stored reverse osmosis RO and granular activated carbon GAC filtrate can be a breeding ground for bacteria.
