Leachate Quality

Leachate is generated during the decomposition process of solid waste and as a result of rainwater percolation through piles of garbage. Leachate composition is influenced by several factors such as the characteristic and density of solid waste, the amount of rainfall and the specific conditions of the disposal site. Once leachate reaches the surrounding soil and groundwater, high concentrations of organic substances will form and remain in the soil and groundwater for a long time. The well-known Indonesian Diponegoro University has built an integrated solid waste treatment plant (ISWTP) to manage the waste generated on site, which is mostly dominated by leaf litter, food waste, paper, and plastic. Organic solid waste goes through a decomposition process and produces leachate. In order to treat the leachate, it is necessary to identify its parameters. Thus, this study examines the effect of solid waste composition and density on leachate quality based on the conditions of the ISWTP. The results showed that the composition of solid waste altered the leachate quality while the density affected the decomposition rate and quantity of leachate.

A bacterial strain OPQa3 capable of utilizing nonylphenol polyoxyethylene (NPnEO) as sole carbon source was isolated from water samples collected from tannery waste treatment plant suffered long-time application of NPnEO by enrichment method. It was preliminarily identified as Brevundimonas sp. (most similar to Brevundimonas diminuta (EU434566.1)), according to the observation of morphological characteristics, physiological-biochemical tests and the similarity analysis of its 16S rDNA gene sequence. Inoculated 2% of OPQa3 suspension, to give a final OD600of approximately 0.70, to inorganic salt medium in which the initial concentration of NPnEO was 746 mg•L-1, degradation test showed that, the degradation rate of strain OPQa3 was 84.5% within 120 hours, the optimum temperature was 30°C while the optimum pH value was about 7, and the growth period was of 24 hours.

This summary presents the cleansing and dismantling operations currently realized on the CEA center of Saclay (CEA-Saclay). It was initiated at the beginning of the 2000 years a cleansing and dismantling program of the old Nuclear Licensed Facilities (NLF). Currently this program relates the dismantling operations to the Hot Laboratories (Laboratoires de Haute Activité: LHA) and the old workshops of the Liquid Waste Treatment Plant (Station des Effluents Liquides: STEL), the dismantling preparation of ULYSSE reactor and the dismantling studies to the Solid Waste Management Plant (SWMP; Zone de Gestion des Déchets Solides) and the OSIRIS reactor.

Animal Sluaghterhouse (RPH) liquid waste contains organic matter, suspended solids, and colloid materials such as fat, protein, and cellulose with high concentrations that fall into the category of complex wastewater. RPH X is a RPH that uses Water Waste Treatment Plant (WWTP) in treating wastewater, although it has been equipped with WWTP there are still some problems in RPH X. The purpose of this research is to describe wastewater treatment and content of BOD, COD, TSS, NH3-N, pH and fatty oil at waste water in inlet and outlet of IPAL RPH X, Jember District. This research is a descriptive research. Technique of data collecting done by observation, interview, and laboratory test. The average of wastewater content test result in RPH X Jember Regency at inlet and outlet of IPAL is at safe limit of quality standard according to East Java Governor Regulation Number 72 Year 2013 except COD parameter at inlet that is equal to 277,6 mg / L. The average percentage of content in liquid waste in RPH X decreases from inlet to WWTP outlet except the pH parameter.

Solid Waste Treatment

Environmental trends and growing tendency to think about ecology play an important role in the development of modern industry. Significant role in this field takes a construction of plants for the processing of municipal solid waste, contributing to the neutralization of the harmful effects by different waste. This article represents development and stages of project implementation for the plant OOO «Kamskoye» that works with solid municipal waste in the city of Chaykovsky, Perm Territory. Investment efficiency of the construction of this facility was calculated. A model of interaction between business and government bodies, which regulate investment to waste disposal projects, is presented. The main structural elements of construction of a plant for processing municipal solid waste are shown. The project was developed using a public-private partnership model. The implementation of the project will ensure the production of secondary raw materials for its further use as an alternative source of heat and electricity generation, as well as the use of products necessary for the market in the production process. The main feature and advantage of the project is the possibility of using a principle «waste to income», which allows to provide your production with energy resources from reusable waste.
