Isolasi dan identifikasi mikroorganisme dalam lumpur aktif pengolahan limbah industri kulit

The aim of this research is to isolate and to identify the microorganisms that grow as activated sludge used in the tannery wastewater treatment plant. The result shows that the protozoa in the activated sludge were β mesosaprobik protozoa. Other microorganisms in the sludge were spherical ? gram negative bacteria (Zoogloea) and cylindrical ? gram positive bacterial (Sphaerotillus). It is therefore can be concluded that the wastewater which treated with the activated sludge was medium polluted condition.
