Phycoremediation of acid mine drainage (AMD) is an alternative to AMD treatment but has limited applications. The obstacle in the application of AMD phycoremediation is that the characteristic of wastewater which limits the growth of microalgae, where AMD has a high metal content and low pH. In this study, Botryococcus braunii was cultured on media with variations in the addition of AMD of (v/v) 0%, 2.5%, 3%, 3.5%, 4% and had a pH of 7.2, 5.6, 5.1, 4.8, 4.3, respectively, on the photobioreactor. Botryococcus braunii growth rate was analyzed, as well as the effect of metal exposure and pH variations on the growth of Botryococcus braunii. Botryococcus braunii showed different growth rates, sequentially from the highest rate in the media with addition of AMD (v/v) 2.5%, 3%, 0%, 3.5%, 4% is 1.403 d-1 ,1.374 d-1 ,0.0862 d-1 ,0.0738 d-1 , and 0.0616 d-1 . It is known that the highest growth rate of Botryococcus braunii is obtained in media with 2.5% (v/v) AMD with an initial pH of 5.6, and Fe and Mn concentrations of 2.15 mg.L-1 and 0.62 mg.L-1 , respectively. It is also known the ability of Botryococcus braunii to adapt to acidic conditions with Fe and Mn content, where Botryococcus braunii plays a role in increasing media pH and is able to remove Fe and Mn with the highest values of 84.28% and 98%, respectively.

Partitioning Procedure

The contamination of sediments with heavy metals may lead to serious environmental problems and in some cases action has to take place for their decontamination. In this work, studies were performed on sediments near the outfall of domestic and industrial waste. The metals examined were Cu, Cr, Ni, Pb, Zn and Fe. Indeed, high metal content was found in the sediments and the contamination factors were quite high, indicating the effect of the nearby discharge of effluents. The results of the application of a sequential extraction partitioning procedure indicated that an important part of the metal content is carried by the residual phase but also a significant percentage is found in the organic and reducible fractions, i.e. in potentially available fractions. Batch extraction experiments using acid solutions of various concentrations and different acid-sediment contact times were performed in order to remove heavy metals from the sediments. For most metals studied, a satisfactory percentage was extracted at low contact times.

In this study, two species of algae from two different areas impacted by acid mine drainage (AMD) were analyzed for metal ion accumulation. The two species of algae collected were Klebsormidium and Entransia. Both algal species are located in an area of high metal ion concentrations and low pH (ranging from 2.28 to 2.89). The study assessed the concentration of iron, manganese, zinc, copper and nickel in the algal tissue. Data shows that both Entransia and Klebsormidium are absorbing or adsorbing iron selectively.

Abstract Low to medium calorie coal reserves dominate Indonesia area. Referring to such amount, the potential for coal synthesis into activated carbon is also massive. The potential utilization of activated carbon from coal to process the acid mine drainage is still developing. This research aims to see the effect of activated carbon to the acid mine drainage from coal mining in a laboratory scale using a weight basis and the contact time between activated carbon and acid mine drainage. The sample is taken from one of the mining locations in East Kalimantan Province. The results showed the effect of the activated carbon weight changes in its pH value, which indicated an increase in pH from 2.19 to a decrease in Fe metal content from 45.2 to 0.1 mg/L and a decrease Mn metal content from 7.22 to 5.3 mg/L. The activated carbon from coal is very effective as an adsorbent for Fe metal but less effective for Mn metal.
