Abstract

Leachate is a liquid generated from waste decomposition containing organic matter, ammonia, heavy metals, and suspended solids in high concentrations. Improper leachate disposal can pollute soil and water around the landfill. This study aims to determine the effect of different idle stabilization techniques on COD, ammonia, and TSS removal efficiency using an aerobic Sequencing Batch Reactor (SBR). Three idle variations were tested: static idle, mixed idle, and aerated idle. The SBR reactor was operated with fill (1 h), react (18 h), settle (2 h), draw (1 h), and idle (2 h) phases for four cycles. The results showed that the aerated idle variation achieved the highest removal efficiencies: COD 86.67%, ammonia 95.36%, and TSS 93.97%. Aerated idle provided better sludge stability and optimal oxygen conditions for microbial activity.

Abstract

The use of boilers and incinerators in the palm oil processing industry will contribute to pollutants in the form ofparticulates (PM2.5 and PM10) which are quite large in number. Particulates are pollutants that have a high level oftoxicity that can endanger human health and the surrounding environment. This study aims to determine the amount ofpollutants resulted from palm oil mills as well as mapping the distribution patterns in the environment. To be able todescribe the pattern of pollutant spread, it starts by identifying the factors that influence the spread of pollutants suchas the amount of pollutants produced, atmospheric stability, wind direction and speed. These data were obtained fromthe Meteorology and Geophysics Agency of Pekanbaru City. To describe the spread of particulate pollutants, asimulation model is used which has been integrated into the AERMod software. The results of the study show that thedirection of the distribution of emissions for pollutants PM2.5 and PM10 from the simulation model results tend towardsoutheast and north from the source. The highest PM2.5 concentration value for the 24-hour was 9.26 µg / m3, thehighest for 1 year was 1.48 µg / m3. The highest value of PM10 concentration for 24 hours is 18.23 µg / m3, the highestfor 1 year is 2.87 µg / m3. The simulation results show that the concentration of pollutants PM2.5 and PM10 originatingfrom boilers and incinerators are below the quality standards of each pollutant.
