超滤设备/Ultrafiltration membrane filter

超滤原理也是一种膜分离过程原理，超滤利用一种压力活性膜，在外界推动力(压力)作用下截留水中胶体、颗粒和分子量相对较高的物质,而水和小的溶质颗粒透过膜的分离过程。通过膜表面的微孔筛选可截留分子量为3x10000—1x10000的物质。当被处理水借助于外界压力的作用以一定的流速通过膜表面时，水分子和分子量小于300—500的溶质透过膜，而大于膜孔的微粒、大分子等由于筛分作用被截留，从而使水得到净化。也就是说，当水通过超滤膜后，可将水中含有的大部分胶体硅除去，同时可去除大量的有机物等。

    超滤原理并不复杂。在超滤过程中，由于被截留的杂质在膜表面上不断积累，会产生浓差极化现象，当膜面溶质浓度达到某一极限时即生成凝胶层，使膜的透水量急剧下降，这使得超滤的应用受到一定程度的限制。为此，需通过试验进行研究，以确定最佳的工艺和运行条件，最大限度地减轻浓差极化的影响，使超滤成为一种可靠的反渗透预处理方法。
    a． 超滤与传统的预处理工艺相比，系统简单、操作方便、占地小、投资省、且水质极优，可满足各类反渗透装置的进水要求。
    b． 合理地选择运行条件和清洗工艺，可完全控制超滤的浓差极化问题，使此预处理方法更可靠。 
    c．超滤对水中的各类胶体均具有良好的去除特性,因而可以考虑扩大到凝结水精处理及离子交换除盐系统的预处理中。
    在超滤过程中，水深液在压力推动下，流经膜表面，小于膜孔的深剂（水）及小分子溶质透水膜，成为净化液（滤清液），比膜孔大的溶质及溶质集团被截留，随水流排出，成为深缩液。超滤过程为动态过滤，分离是在流动状态下完成的。溶质仅在膜表面有限沉积，超滤速率衰减到一定程度而趋于平衡，且通过清洗可以恢复。
    超滤是以压力为推动力的膜分离技术之一。以大分子与小分子分离为目的，膜孔径在20－1000A°之间。中空纤维超滤器（膜）具有单位溶器内充填密度高，占地面积小等优点。

Instruction

1. Ultrafiltration is a separation technique widely used. Mainly the use of polysulfone, microporous Polyethersulfone ultrafiltration membranes (molecular weight cut thousands of ten thousands
Daltons) filter out impurities in the water can be removed more than 98% organic matter, to ensure
That the treated water is less than 1 SDI, the SDI value, the turbidity is very satisfactory. The
Pretreatment facilities are exempt large, does not need the coagulant, flocculation, comply with
Environmental requirements.

2.Ultrafiltration membrane is the anisomerous semipermeable membrane made of macro molecule material as the separation method without phase transition for solution, and can remove particles whose molecule weight ranges 1, 500-100, 000Dalton, and can effectively remove organic, bacterium, virus, colloid and non-ion suspended solid.
