Patent ID: 11136247

Abstract:
A nanocomposite composition for controlling water hardness and a method of producing the nanocomposite, is disclosed. The nanocomposite composition comprises a plurality of semi-interpenetrating polymer network/zeolite-silver nanocomposite, including a polymer matrix. The polymer matrix is dispersed with a plurality of zeolite nanoparticles and a plurality of silver nanoparticles. The method of producing semi-interpenetrating polymer networks/zeolite-silver nanocomposite as hydrogel form comprises microemulsion polymerization of monomeric mixture uses methyl methacrylate (MMA) in presence of ethylene glycol dimethacrylate (EGDM) cross-linker for MMA monomer, acrylamide (AAm), acrylic acid (AAc) and linear poly vinyl alcohol (PVA) monomers in the presence of N,N′-methylene bisacrylamide (MBA) cross-linker and TX-100 surfactant. Further, the prepared nanocomposite is a water hardness removal filter and an efficient inhibition of sulfate-reducing bacteria nanocomposite. Also, the water filter cartridge exhibits a stable filtration performance during large scale production with reduced fluctuation infiltration flow rate and shows highly stable behaviors in high salt concentration.
