ABSTRACT:
A device for the purification of water and methods for the use thereof are disclosed. The device comprises a closed container substantially porous to water, a purification agent contained therein and an ingredient dispersed in the purification agent for the purpose of inhibiting fine particles of the agent from escaping the container when the device is immersed in water. The disclosed inhibitory ingredients include certain modified starches, wood flour and aluminium lanolate soap.
The device is especially useful in removing incipient impurities from drinking water that can elude customary water treatment and render drinking water organoleptically unsatisfactory.
