The study of laboratory wastewater processing by application of integrated wastewater processing equipment using continous system had been done. The wastewater used in this study was wastewater for COD testing. Variables in this study were dilution factor (fP) with the following compositions : 50:100 (fp.2), 40:100 (fp.2.5), 20:100 (fp.5) and 10:100 (fp.10). The results showed that equipment of integrated laboratory wastewater processing had optimum perfomance at dilution factor of 2.5 (fp.2.5) to 5 (fp.5). This condition produced the pollutant elimination percentage value of Total Dissolved Solids (TDS), Ammonium (NH3-N), Iron (Fe), Total Chrome (Cr-total) and Mangaan (Mn)respectively in the ranges of 90-95% with the final acidity level (pH) of laboratory wastewater in the range of 6-7.
