Ultrafiltration membrane equipment

1、概 述： 

1.Overview

    超滤膜过滤是以膜两侧的压力差为驱动力，在一定的压力下，当原液流过膜表面时，超滤膜表面密布的许多细小的微孔只允许水及小分子物质通过而成为透过液，而原液中体积大于膜表面微孔径的物质则被截留在膜的进液侧，成为浓缩液，因而实现对原液的净化、分离和浓缩的目的。超滤的过滤精度在0.005-0.01μm范围内，可有效去除水中的微粒、胶体、细菌、热源及高分子有机物质，广泛应用于物质的分离、浓缩、提纯。与传统分离方法相比，超滤膜技术在液料过滤分离过程中具有以下特点：

1、无污染、无残留，是一项绿色环保技术；

2、分离精度高，透过液澄清透明，大大减轻后续精制工艺负荷，同时提高产品中有效成分的含量；

3、过滤过程仅采用压力作为膜分离的动力，分离装置简单，操作简便，工艺参数易于控制；

4、工序简化，工艺流程短，生产周期大大缩短；

5、膜工艺过程不发生相变化，无需添加药剂，十分节能，可大大降低运行成本。

Ultrafiltration membrane filtration is the pressure difference on both sides of the membrane as the driving force, under a certain pressure, when the liquid through the membrane surface, the ultrafiltration membrane surface of many small pores only allow water and small molecules through And the substance in the stock solution is larger than the microporous diameter of the membrane surface. The substance is separated into the liquid feed side of the membrane and becomes a concentrated liquid, thereby achieving the purpose of purifying, separating and concentrating the stock solution. Ultrafiltration filtration efficiency in the range of 0.005-0.01μm, can effectively remove the water particles, colloids, bacteria, heat and polymer organic substances, widely used in the separation of substances, concentration, purification. Ultrafiltration process without phase conversion, operating at room temperature, the separation of heat-sensitive substances is particularly appropriate, and has good temperature, acid and alkali and oxidation resistance, can be below 60 ℃, pH 2-11 under the conditions of long-term continuous The use of ultrafiltration is a "cross-flow filter" in the form of fluid separation process, the raw material in the membrane surface (tube hole) within the high-speed flow, driven by the pressure of small molecules within the clarified permeate along with vertical or tangent Direction outward through the membrane, containing macromolecular components of the concentrate film retention, so that the fluid to achieve separation, concentration, purification purposes. Compared with the traditional separation method, the ultrafiltration membrane technology in the liquid material separation process has the following characteristics:

1, no pollution, no residue, is a green technology;

2, high separation accuracy, clear and transparent through the liquid, greatly reducing the follow-up refining process load, while improving the content of active ingredients in the product;

3, the filtration process only uses the pressure as the membrane separation power, the separation device is simple, the operation is simple, the craft parameter is easy to control;

4, the process is simplified, the process is short, the production cycle greatly shortened;

5, the film process does not occur phase change, no need to add pharmaceuticals, very energy efficient, can greatly reduce operating costs.
