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。活性碳吸附过滤器缸体采用水力模拟长径设计，并采用粒径合理，比表面积大于 1000㎡/g的高效活性碳，使其既有上层*过滤又有下层高效吸附等功能，大大提高产水净化程度和碳的使用寿命。经活性碳吸附过滤器处理后水质余氯含量:≤0.1PPM。对水体中异味、有机物、胶体、铁及余氯等性能*;对于降低水体的浊度、色度，净化水质，减少对后续系统(反渗透、超滤、离子交换器)的污染等也有很好的作用。一种罐体的过滤器械，外壳一般为不锈钢或者玻璃钢，内部填充活性炭，用来过滤水中的游离物、微生物、部分重金属离子，并能有效降低水的色度。Activated carbon filter is a kind of commonly used water treatment equipment, water treatment desalination system as pretreatment can grade filter before adsorption can't remove the residual chlorine, which can effectively guarantee the equipment service life, improve water quality, pollution prevention, especially to prevent reverse osmosis membrane, ion exchange resins such as pollution of free residual chlorine poisoning.At the same time, it also absorbs pollution substances such as small molecule organic matter from previous leakage, which has obvious adsorption and removal effect on peculiar smell, colloid, pigment and heavy metal ions in water, and can also reduce COD.The SDI value of RO water inflow can be further reduced to ensure that SDI<5 and TOC<2.0 PPM.
