Latest Patents

One of Liu's latest patents is titled "Preparation of molecular sieve and treatment of silicon-containing wastewater therefrom." This method involves treating silicon-containing wastewater by contacting it with acids or alkalis, leading to the formation of colloids. The process results in a silicon-containing solid phase and a first liquid phase through solid-liquid separation. Additionally, the second liquid phase undergoes electrodialysis to produce acid and/or alkali liquors, which can be utilized in molecular sieve synthesis.

Another significant patent is the "Ion-exchange process." This process includes a bipolar membrane electrodialysis step that produces an acid liquid from an aqueous ion-containing solution. The ion-exchange step involves contacting an exchangeable-ion containing solid material with the acid liquid, resulting in a slurry that undergoes solid-liquid separation. The liquid phase is then adjusted to a pH of 4-6.5 before further treatment.
