Abstract

The invention belongs to the technical field of ultrafiltration systems, and in particular relates to a novel ultrafiltration device, which includes a waste water pool, a high-concentration electric adjustment switch, a high-concentration liquid feeding device, and a diluted liquid feeding device. The waste water pool is connected to a high-concentration filter membrane , the top of the high-concentration filter membrane is provided with a high-concentration liquid feeding device, and the bottom is provided with a low-concentration filter membrane, and the ultrafiltration membrane is located in the middle between the high-concentration filter membrane and the low-concentration filter membrane, and the transmembrane The pressure sensor is located on both sides between the high-concentration filter membrane and the low-concentration filter membrane, and a dilute liquid feeding device is arranged above the low-concentration filter membrane. The present invention regulates the transmembrane pressure and flow by adjusting the high-concentration electric adjustment switch and the low-concentration electric adjustment switch, so that the transmembrane pressure and flow can reach the most reasonable ultrafiltration conditions, greatly improve the membrane permeability and sample yield, and make High ultrafiltration efficiency.

Description

technical field [0001] The invention belongs to the technical field of ultrafiltration systems, and in particular relates to a novel ultrafiltration device. Background technique [0002] Ultrafiltration is a membrane separation process with sieving as the separation principle and pressure as the driving force. It can effectively remove particles, colloids, bacteria, heat sources and high-molecular organic substances in water. It can be widely used in the separation, concentration, Purify. The current ultrafiltration system cannot adjust the transmembrane pressure and flow, and cannot achieve the most reasonable ultrafiltration conditions. The membrane permeability and sample yield are low, and the ultrafiltration efficiency is low. Contents of the invention [0003] The present invention provides a novel ultrafiltration device to solve the problem that the current ultrafiltration system in the background art cannot adjust the transmembrane pressure and flow. [0004] The...
