Reed is able to absorb water, a quality that enables using it as a cartridge filler in eco-friendly filters to address the contamination of waterbodies. Aside from capturing harmful substances and pathogens, such filters actively absorb water. As the filtering medium becomes saturated with a fluid, its absorption capacity degrades, which is why one needs to know the saturation rates if the water purification process is to be effective. This knowledge helps find out how frequently the cartridge filler must be replaced. Absorption rates were sufficient for purification for three hours as shown by experimental laboratory tests using reeds ground to a variety of specific particle sizes without additional processing that would modify its structure physically and chemically. This indicates that cartridges have to be refilled with a new biosorbent at least twice over the daily period of bacterial activity observable from 10 am to 4 pm during daylight hours.
