Title: Innovations by Larry A. Lien

Introduction

Larry A. Lien is an accomplished inventor based in Solana Beach, California. He has made significant contributions to the field of water treatment and fuel supply systems. With a total of 5 patents to his name, Lien's work focuses on innovative methods that enhance efficiency and sustainability.

Latest Patents

One of Lien's latest patents is for a method of reclaiming spent aqueous brine solutions used in the regeneration of water-softening resins. This method involves acidifying an aqueous solution of chloride or other brine with HCl to a pH between about 0.5 and 6. A soluble sulfate salt, preferably Na₂SO₄, is added along with a precipitation inhibitor such as polyacrylamide. The spent brine is then pumped at high pressure through a spirally-wound nanofiltration-type membrane device, effectively removing at least 90% of the divalent hardness while allowing passage of at least 90% of the monovalent cations. This process enables the efficient reclamation of about 90 to 95% of the spent brine for reuse in regenerating water-softening resins.

Another notable patent by Lien is for an apparatus designed to supply decontaminated fuel to a diesel engine. This apparatus includes two filtering stages: the first being a spiral wound, cross-flow ultrafiltration unit, and the second a spiral wound deadheaded ultrafiltration unit. A pressure-operated alarm is connected to respond to the build-up of contaminants in the second stage, ensuring the delivery of clean fuel to the engine.
