The Biological Treatment Method for Landfill Leachate
E3S Web of Conferences 202, 06006 (2020) https://doi.org/10.1051/e3sconf/202020206006 ICENIS 2020 The biological treatment method for landfill leachate Siti Ilhami Firiyal Imtinan1*, P. Purwanto1,2, Bambang Yulianto1,3 1Master Program of Environmental Science, School of Postgraduate Studies, Diponegoro University, Semarang - Indonesia 2Department of Chemical Engineering, Faculty of Engineering, Diponegoro University, Semarang - Indonesia 3Department of Marine Sciences, Faculty of Fisheries and Marine Sciences, Diponegoro University, Semarang - Indonesia Abstract. Currently, waste generation in Indonesia is increasing; the amount of waste generated in a year is around 67.8 million tons. Increasing the amount of waste generation can cause other problems, namely water from the decay of waste called leachate. Leachate can contaminate surface water, groundwater, or soil if it is streamed directly into the environment without treatment. Between physical and chemical, biological methods, and leachate transfer, the most effective treatment is the biological method. The purpose of this article is to understand the biological method for leachate treatment in landfills. It can be concluded that each method has different treatment results because it depends on the leachate characteristics and the treatment method. These biological methods used to treat leachate, even with various leachate characteristics, also can be combined to produce effluent from leachate treatment below the established standards. Keywords. Leachate treatment; biological method; landfill leachate. 1. Introduction Waste generation in Indonesia is increasing, as stated by the Minister of Environment and Forestry, which recognizes the challenges of waste problems in Indonesia are still very large. The amount of waste generated in a year is around 67.8 million tons and will continue to grow in line with population growth [1].

Performance Evaluation of Integrated Treatment Plant of Trickling Filter and Constructed Wetland
P.M Maheesan et al. / International Journal of Engineering Science and Technology (IJEST) Performance evaluation of integrated treatment plant of trickling filter and constructed wetland P.M Maheesan1, G Srinikethan2 and Harikumar, P.S3 1 Principal, Swami Nithyananda Polytechnic College Kanhangad 671315 India 2 Professor, Chemical Engineering Department National Institute of Technology Karnataka 575025 India 3 Scientist, Centre for Water Resources Development and Management Calicut 673571 India; ABSTRACT A system consisting of trickling filter followed by a vertical intermittent flow constructed wetland system under laboratory condition was evaluated for the treatment of domestic wastewater. The system was able to produce final effluents with low concentrations of both organic and nutrients. Mean effluent concentrations were, respectively: BOD: 22.22mg/L;COD:64.58mg/L;SS:27.63mg/L;NH4-N:0.62mg/L;P:1.72mg/L. The study shows that the integrated treatment system of trickling filter and vertical intermittent flow constructed wetlands can be effectively used a treatment option for a treatment with positive attributes of conceptual simplicity and lesser energy consumption. INTRODUCTION The trickling filter reactors are widely recognized as an appropriate option for the treatment of domestic wastewater in tropical developing countries. The main advantages include simplicity, no mechanization, low sludge production and less energy consumption. However, trickling filters show lower removal efficiencies compared with other secondary processes, which brings about the need for a post treatment of their effluents, especially in terms of organic matter and nutrients. In order to improve water pollution control, removal of nutrients is of great importance. This fact has obviously influenced the water legislation in this field in many parts of the world (Haberl, 1999).

Abstract:- Wastewater contains high number of organic solids consists of low number of organic solids and inorganic and harmful contaminants. Due to these harmful substance solids comparatively low than wastewater but these grey wastewater treatments is essential but many developed and waters is one of the major parts of wastewater so developing countries like India cannot construct and maintain treatment of grey water in house itself reduce the volume the conventional centralized sewage treatment plants due to of wastewater production. untreated grey water consists of high cost of treatment and high amount of wastewater production. So, cost effective and eco-friendly decentralized high amount of microorganism. These pathogens make sewage treatment system is needed in small areas. Hence grey water as harmful. So, treatment is essential before vermifilteration can be very effective for small villages and usage. According to United States Environmental colonies. In this system filter bed is inoculated with Protection agency, grey water can be treated to varying earthworms (Eisenia fetida). these earthworms body works as degrees U (victor G.Ngnaga et. al,2012) It can be treated a “biofilter” and it has high efficiency to remove BOD, using various secondary treatment. Mainly we have used COD.TSS by the general mechanism of biodegradation and Activates sludge process, waste stabilization pond, adsorption of organic wastes.

Tatoulis 2 and Athanasia G. Tekerlekopoulou 2,* 1 Department of Civil Engineering, Democritus University of Thrace, GR-67100 Xanthi, Greece; [email protected] 2 Department of Environmental Engineering, University of Patras, GR-30100 Agrinio, Greece; [email protected] * Correspondence: [email protected]; Tel.: +30-2641074204 Received: 18 December 2019; Accepted: 13 January 2020; Published: 15 January 2020 Abstract: The objective of this work was to determine the ability of a pilot-scale hybrid system to treat real (non-synthetic) winery wastewater. The experimental treatment system consisted of two stages: An attached growth pilot-scale bioreactor (biological trickling filter with plastic support material) was initially used to remove a significant amount of dissolved chemical oxygen demand (d-COD) from winery wastewater, and then a pilot-scale, horizontal subsurface flow constructed wetland (CW) was examined as a post-treatment step for further d-COD removal. Results from the biofilter revealed that the recirculation rate of 1.0 L/min lead to higher d-COD removal rates than that of 0.5 L/min for all feed d-COD concentrations tested (3500, 7500, 9000 and 18,000 mg d-COD/L). Experiments in the CW were performed using feed d-COD concentrations of about 1500 mg/L (equivalent to biofilter effluent when initial filter feed d-COD concentrations are 18,000 mg/L). The wetland polishing stage managed to further remove d-COD and produced effluent concentrations below current legislation limits for safe disposal.
