2) Silt density index
污染密度指数
1.
Silt density index(SDI)is a most important index of evaluating water pretreatment effect of RO system.
污染密度指数(SDI)是评价反渗透(RO)系统进水预处理效果的最主要指标,现有的一些SDI测试主要采用人工测量,不但费时费力,而且容易产生人为误差,难于满足企业自动化的发展要求。
3) Pollution-intensive
污染密集
1.
The Environmental Effect of China s Trade of Pollution-intensive Industrial Goods;
我国污染密集型工业品贸易的环境效应研究
4) pollution level
污染程度;污染度
5) pollution concentration
污染浓度
6) fouling degree of membrane
膜污染度
1.
