The use of clean water for wet scrubbers needs to be reduced for water resource efficiency in the company. This research was conducted to examine the use of wastewater as wet scrubber feeding from boilers that use coal fuel. The scrubber type was spray tower using stainless steel material and packed bed with marbles. Artificial waste was made to imitate textile wastewater. Emission measurements at the outlet adopted SNI standard. Parameters observed in the flue gas were particulate (isokinetic), SO 2 , and NO 2 . We also observed the TSS and COD concentrations in the scrubbing liquid. The reduction pollutants concentration using artificial waste was 21 - 51% for particulate, about 45% for SO 2 concentration, and more than 90% for NO 2 concentration. The parameters of COD concentration in the outlet decreased by about 20% while the TSS concentrations increase almost two fold. This initial study shows that the use of wastewater for scrubbers is promising although it produced TSS pollutants in scrubbed wastewater.
