活性炭过滤器是一种较常用的水处理设备，作为水处理脱盐系统前处理能够吸附前级过滤中无法去除的余氯,可有效保证后级设备使用寿命，提高出水水质，防止污染，特别是防止后级反渗透膜，离子交换树脂等的游离态余氯中毒污染。同时还吸附从前级泄漏过来的小分子有机物等污染性物质，对水中异味、胶体及色素、重金属离子等有较明显的吸附去除作用，还具有降低COD的作用。可以进一步降低RO进水的SDI值，保证 SDI<5，TOC<2.0ppm。

活性炭过滤器的注意事项：

1、泵入口的吸油粗滤器;

2、泵出口油路上的高压滤油器;

3、系统回油路上的低压滤油器;

4、安装在系统以外的旁路过滤系统。

5、由于活性炭过滤器的活性炭吸附功能具有一定的饱和值，当达到饱和吸附容量时，活性炭滤池的吸附功能将大大降低，因此需要注意分析活性炭的吸附能力，及时更换活性炭或者通过高压蒸汽进行消毒恢复。

Activated Carbon Filter is a kind of common water treatment equipment. As the pre-treatment of water treatment and desalting system, it can absorb the residual chlorine which can not be removed by the pre-filter, and can effectively guarantee the service life of the post-filter, improve the quality of the effluent, and prevent pollution, in particular, to prevent the after-stage reverse osmosis membrane, Ion-exchange Resin, such as free residual chlorine pollution. At the same time, it also adsorbs the small molecule organic matter and so on, which has obvious adsorption and removal function to the peculiar smell, colloid and pigment, heavy metal ion in the water, and also has the function of reducing COD. It can further reduce the SDI value of Ro influent and ensure Sdi & LT; 5, Toc & Lt; 2.0 PPM. Active carbon filter notes: 1, the pump inlet suction coarse filter; 2, the pump outlet oil on the high-pressure filter; 3, the system return oil on the low-pressure filter; 4, installed outside the system bypass filter system. 5. Because the adsorption function of activated carbon of activated carbon filter has a certain saturation value, when the saturated adsorption capacity is reached, the adsorption function of activated carbon filter will be greatly reduced, therefore, it is necessary to pay attention to the analysis of the adsorption capacity of activated carbon, timely replacement of activated carbon or through high-pressure steam disinfection recovery.
