UJI EKOTOKSISITAS MIKROBIAL UNTUK PENENTUAN BEBAN VOLUMETRIK SUATU PARAMETER MUTU DALAM PENGOLAHAN MIKROBIAL AIR DAN LIMBAH

Abstract

The weakness of conventional method is background the test of ecotoxicity mikrobial for processing mikrobial water and wastewater. From study we can hypothesis that there is correlation among volumetric mass and concentration level activity mikrobial equal to 50 % ( EC - 50 - TD). With the method test of ecotoxicity mikrobial yeast in a anaerobik condition during 2 hours, that possibility searched for the parameter quality of COD, NO^-3, PO₄^3-, Mn²⁺ and Fe²⁺. From the result give information of level of BV and EC - 50 - 2 hours and correlation between both of them; that is BV can be increasing as long as concentration input to the reactor mikrobial minimized or on the contrary.
