ABSTRACT:
The present invention relates to a water absorbent packet and the method of using the packet in liquids to be kept free of invasive water. The packets are made of sheets of material which allow the water in the liquid to penetrate into the packet and contact the water absorbent material. Any water present in the liquid which contacts the absorbent material is absorbed from the liquid.
The packets can be manufactured to the size desired for use in the system to be kept water free and the desired number of compartments of absorbent material. The amount of absorbent material in the compartments can be measured so that upon water absorption the compartment becomes swollen, giving a visual check for the presence of water. The absorbent compound of this invention can be sodium poly-2-propenoate, carboxymethyl cellulose or other form of the super absorbent composition or polymers which will not migrate through the sheets of material when placed in the liquid and when water is absorbed from the liquid. The packets can be constructed from sheets of polyester cotton fabric bonded so that compartments are formed enclosing the super absorbent material.
