It is considered to be a valid method for using the waste water of an industrial plant to control the air pollution of the exhaust gas (e.g. ammophos complex fertilizer industry, oil drilling waste reduction, etc), which is one of the main sources of atmospheric particulate matter also in China. A new GLCA (Gas-Liquid Cross-flow Array) wet scrubber system is proposed to reduce particulate matter, especially PM2.5 at a comparable low pressure drop. Thereby, water is formed into a continuing and regular liquid columnar array to separate the exhaust gas particles. These dust collector array is perpendicular streamed by the dusty gas flow and particles can be captured by the water columns. Compared to traditional dust separators, the GLCA system has advantages of self-renewable liquid surfaces, waste water without special pre-treatment can be employed to form the liquid columns in the system and a comparable low pressure drop. So it can be taken as an alternative dust separator, applied in e.g. chemical industries, electric power plants… in which waste water arises.

Further a method was worked out, how to assess the PM2.5 separation behaviour of dust separators with a PM2.5 separation efficiency factor. Experiments on a GLCA-lab-scale test rig have been ..
