RX Dynamic Crossflow Filtration System

Product introduction:

The dynamic cross-flow filtration system of rotating tubular membrane is a membrane filtration system that utilizes rotating tubular membrane filtration technology to achieve continuous operation. It utilizes rotating membrane tubes to achieve dynamic cross-flow, thereby avoiding membrane clogging and fouling problems that exist in traditional pressure difference-driven membrane filtration systems. This system is suitable for particle and liquid separation applications that have higher requirements for suspended solids, colloids and polymers, such as biotechnology, food and beverage, pharmaceutical and chemical industries, as well as various industrial waste (acid) water, coal chemical industry black water desolidification and other fields.

Under the action of the pump and pressure (2-3kg), high-viscosity and high-concentration materials are driven into the membrane module for high-speed rotation. The filtrate passes through the membrane pores in a tangential manner under the action of pressure and flows out through the hollow shaft. The concentrate (solid matter) forms turbulent flow due to high-speed rotation, which continuously washes the surface of the membrane to prevent the solid matter from staying on the surface of the membrane disc, thereby effectively preventing fouling on the membrane surface and ensuring normal filtration, thereby achieving a concentration effect.

Centrifugal action:

The centrifugal force is used as a driving force and does not rely on the feed pump to provide large circulation flow and operating pressure. The material liquid can be segmented. The faster peripheral linear speed can better cope with high-concentration materials and save significant energy;

Turbulence effect:

Turbulence is constantly formed inside the system, and the shear force of the outer wall is increased by more than 50% compared with traditional cross-flow filtration, which can better suppress filter cake accumulation and slow down the flux decay;

Double-sided filtering:

The two outer working surfaces increase the effective filtering area within the equivalent volume.

Filtration principle:

1) The new concentration filtration equipment effectively combines the principles of centrifuge and ceramic membrane, and is an enhanced membrane separation technology;

2) The membrane flux does not decline, is less affected by the concentration of the feed liquid, and has a long continuous and stable filtration time;

3) It can effectively prevent the clogging of the filter membrane and ensure the normal operation of filtration.

Advantages:

High separation efficiency: Compared with traditional filtration and centrifugal separation technologies, the system has higher separation efficiency.

Easy operation: The system is easy to operate, easy to maintain and clean, and has low personnel training costs.

Low cost: The system has lower operating costs and longer service life, which can reduce the customer's overall cost.

Good stability: The rotating tubular membrane used in this system has good stability and can maintain efficient filtration effects during long-term operation, reducing maintenance costs and downtime.

Energy saving and environmental protection: The rotating tubular membrane used in this system can effectively reduce energy consumption and carbon dioxide emissions, and meets the development requirements of modern energy saving and environmental protection.

Wide scope of application: The dynamic cross-flow filtration system of rotating tubular membranes can be widely used in municipal water supply, industrial wastewater treatment, seawater desalination and other fields, and has broad market prospects.

Product principle:

The butterfly ceramic membrane obtains inter-membrane pressure through rotation, and the permeate enters the permeation channel inside the butterfly ceramic membrane through the membrane surface, and then flows out of the system through the hollow central axis.
