STUDI PENENTUAN JENIS OUTLET LIMBAH CAIR KARET REMAH UNTUK PERTUMBUHAN MIKROALGA DENGAN SISTEM OPEN PONDS
ABSTRACT: Waste water of crumb
rubber industry is originated from coagulation, milling and leaching stage
contains organic material that is derived from serum and rubber particles which
haven’t been coagulated yet. The materials are potential to pollute the water
therefore the crumb rubber industry must be treated through the wastewater
plant. However, the characteristics of waste water are predicted suitable for
the cultivation of Nannochloropsis sp. media a biofuel feedstock, especially
biodiesel that can be used as an energy source.
The purpose of this study was to determine the kind of the outlet of the
crumb rubber waste water suitable for growth microalgae with open ponds
system. This study was conducted in two
phases: the first is the characterization of wastewater. Waste water used is
waste water crumb rubber derived from Facultative ponds II (F2), an Aerobic I
pond (Ae1), and an Aerobic II pond (Ae2) with a working volume of each 5 L as a
three-stage treatment of growth Nannochloropsis sp. media. The second phase is
the cultivation of Nannochloropsis sp. as much as 25% v / v of work. The
observations those have been done are: microalgae density (OD), analysis of
N-NH3, N-total, P-PO4, pH, temperature, content of Chemical Oxygen Demand
(COD), Dissolved Oxygen (DO) and dried Yield acquisition. The optimum result of
Nannochloropsis sp. growth is on waste water Facultative II pond media with
density of cell is about 3.3 x 107 cells / mL. Moreover, it can degrade the
organic matter content of waste water crumb rubber in the form of N-NH3 reaches
98%, P-PO4 89%, N-total 92%, and the dry yield of micro algae 0.87g /L.
