Abstract

Leacheate could be defined as a liquid from the biological decomposition of decomposed waste that caused by external water that flowing in into the pile of waste. Leacheate caused by a prescipitation liquid into the Final Disposal, both from the rain infiltration or from the water content of the waste itself. Leachate is toxic due to impurities in the deposits that may be derived from industrial waste disposal, dust, the result of processing waste, household hazardous waste, or from the normal decomposition that occurs in trash. If the problem doesnt solved then the landfill that fille with leacheate could contamine the environment and more specific it would contamine ground water and surface water.
The aim of this research was to determine the optimal method that could be use to reduce metal content on leacheate liquid waste. The benefit of this research was to get a solution for treating leacheate liquid waste and to gain a knowledge aout the usage of zeolit as leacheate waste treatment media. The research has been done on May – July 2011 and taken place at Natural Resources and Environmental Laboratory of Brawijaya University. The research used randomized design group for the experimental method with 0.05 as the confidence interval value.
The results of this study showed the levels of chromium (Cr) was at 0.3892 mg / l and the result treatment that have the most decreasing rate of chromium is at 0.1751 mg / l, while the result for Lead (Pb) is at 2.2923 mg / l and the average result treatment with the best decreasing rate is 0.3940 mg / l at the retention time of 3 weeks. Selection of the best treatment is based on qualitative parameters of wastewater, which is allowed according to the waste quality standard set by the government and different residence time in combinatiaon treatment. Selection of the best treatment P1Z2 give the average Cr content of the smallest since the levels of Cr on initial observation and after treatment P and Z has decreased significantly. And also on treatment P2Z2 give the decreasing rate for the smallest Pb. Pb is a levels at the beginning of the observation and treatment after being given P and Z. Both of these treatments can be interpreted that the treatment effect on levels of Cr and Pb.

Key words : Leacheate liquid waste, zeolit, batch type and continuous type

Reduction of Pb and Cr Metals Contents of Leachate by means of Phytoremediation of Bambu Air (Equisetum hyemale) and Zeolite

February 17th, 2012 No comments

Summary
The very large numbers of trash in the TPA (end disposal place) will cause the natural decomposition process goes on massively as well. The decomposition process will change trash into organic fertilizer that if there any water input from the outside, it will dissolve metals that later become the byproduct that is leachate. The introduction of chemical contained in the leachate into the waters ecosystem may also affect the existing biota. Therefore, it is need the waste treatment before released into the environment. Leachate waste treatment by using the phytoremediation principle by means of Bambu air plant (Equisetum hyemale), with zeolite planting media was to be the choice in the effort of liquid waste treatment the Phytoremediation system was taken with a various considerations that very potential to develop into new innovation in the process of leachate waste treatment.
This research had the purpose to know the effectiveness of phytoremediation system using water bamboo plant (Equisetum hyemale) and zeolit planting media by batch system and continue system in reducing Pb and Cr heavy metals contents of leachate. This research was conducted on May through July 2001 at the Green House of Natural and Environmental Resources Engineering Laboratory (TSAL) of Agricultural Engineering Matter Department, Agricultural Technology Faculty of Brawijaya University, Malang. Research method used was the experimental method. Observations carried out involved environmental temperature and humidity, solution pH and treatment temperature, Reduction of Pb and Cr Metals Contents on leachate.
Batch system and continue system as a whole, mean of leachate pH tested during this treatment was about 7,466. Leachate pH tested did not less than 7,200 and not more that 7,810. Mean of leachate temperature from the first week through third week was of 22,283°C.
