Abstract

The design of the laboratory liquid waste treatment reactor aims to treat laboratory waste so it is environmentally friendly based on physical and chemical parameters. Reducing the concentration of waste close to or in accordance with the quality standards of liquid waste and also as a waste treatment model that utilizes agricultural waste as reactor stuffing to process laboratory waste to be environmentally friendly. This research also adds economic value to cocoa skin waste, so that cocoa farmers get additional income from cocoa shells. The optimum conditions in the design of this tool occur at a flow rate of 21.94 mL / sec, the height of the adsorbent 20 cm so as to reduce the value of TSS (Total Suspended Solid) with an efficiency of 62,285% and TDS (Total Dissolve Suspended) with an efficiency of 19,415% and at optimum conditions have a pH value of 7. The method applied in this study is the filtration method and the absorption or adsorption method. The sample flow from the bottom up so that the contact between the adsorbent and the waste in the reactor is maximal because of the influence of pressure and gravity. The result of this process is the formation of fine sediments between adsorbents.

Abstract

The liquid waste processing reactor is a toll used to reduce impurities in waste, including heavy metals. the laboratory is the center of research and produce various wastes, both physical, chemical and biological. Cocoa shells is an agricultural waste and is one the organic waste whose volume is abundant, which the disturbs the environment, which causes unpleasant odors and a medium for insects. Cocoa shells have the potential to be processed into charcoal because the contain high cellulose, hemicellulose and lignin. The use of cocoa shells charcoal as an adsorbent for Cu2+ contained in laboratory waste is a solution to reduce environmental pollution by utilizing agriculutural waste to treat laboratory waste.The purpose this research was to determine of the optimum conditions for the waste treatment reactor including the diameter of the adsorbent particles, the height of the adsorbent in the reactor and the flow rate of waste passing through the reactor column. Waste treatment system with a continuous system and waste analysis before and after passing through the reactor using AAS.Preparation of cocoa shell charcoal by heating at a temperature of 140 oC for about 4 hours.The optimum conditions for the reactor occurredat a particle diameter of 120 mesh, an adsorbent height of 25 cm and a rate of 68,39 mL/second in the reactor column with a diameter of 2 inches and height of 50 cm.The effectiveness of the reactor using cocoa shell charcoal at the optimum conditions.
