Comprehensive Picture

This paper presents a strategy for an investigation to give a comprehensive picture of a biological filter aimed for treatment of different kinds of wastewaters, such as landfill leachate, stormwater and wastewater from vehicle washes. The strategy is based on batch equilibrium experiments and includes three main parts. Under focus is the ability of the filter material to simultaneously remove organic and inorganic pollutants from wastewater, as well as the environmental impact of using materials that would normally be waste to build filters, on one hand, and of disposing of used filter material on the other. The filter material used in these tests is naturally occurring materials such as peat and residual products such as carboncontaining ash. A filter material in a treatment system needs eventually to be exchanged either because it has been saturated by pollutants or because the hydraulic conductivity has decreased too much. After usage the filter material is considered solid waste and is to be classified and handled according to that. Several possible alternatives for further handling, i.e. landfilling, combustion or composting can be selected. A characterization of filter material used for three years in a full-scale filter system for landfill leachate treatment has revealed that energy recovery at an incineration plant could be a possible handling alternative for the used filter material.

Leachate has been reported as the most significant source of landfill pollution. Predicting the characteristics of untreated and treated leachate may be useful during optimal scheduling of leachate treatment systems. The objective of this paper is to show an analysis of the operation of a landfill leachate treatment system in a Latin American megacity (Bogota, Colombia) by means of auto-regressive integrated moving average (ARIMA) models. A comparative analysis of the leachate treated with respect to reference legislation is carried out. The influence of climate variables during the operation of the treatment system is also considered. The results suggest that the concentrations of heavy metals (HMs), BOD5, and COD in untreated leachate do not follow the same annual cycles observed for the quantity of solid waste disposed within the landfill. This difference is possibly associated with the hydraulic retention time (HRT) of the leachate inside the conduction and pre-treatment system (storage/homogenization ponds). The ARIMA analysis suggests an HRT of up to one month (AR = 1) for the HMs identified as indicators of untreated leachate (Cu, Pb, and Zn). It is noted that the removal efficiency of HM indicators of the operation of the leachate treatment plant (Fe and Ni) is probably conditioned by operations carried out over a period of one month (AR = 1). The high input concentration of these HM indicators may prevent changing their ARIMA temporal structure during leachate treatment. This is reflected in the low removal efficiencies for all HMs under study (average = 26.1%).

Landfilling is one of the most widely used forms of solid waste disposal, yet the management of landfill leachate is challenging because of the complex composition and high contaminant concentration. This study provides an on-site treatment system to treat 500 m3 day-1 of the leachate generated from the Perdido Landfill in Escambia County, Florida. The main concerns of the landfill leachate are ammonium-nitrogen, total dissolved solids (TDS) and biological oxygen demand (BOD) from the long-term monitoring (from September 1999 to May 2015). To target these major contaminants as well as other pollutants, we designed a wetland treatment system by fully utilizing the existing facilities at the Perdido Landfill site. The modified wetland treatment system consists of five components in series: leachate collection/aeration ponds, anaerobic ponds, aerobic ponds, wetlands and limestone filter ponds. The leachate collection/aeration ponds provide functions of nitrification as well as ammonia and CO2 stripping. The following anaerobic ponds focus on nitrogen removal by denitrification. The BOD is removed in the aerobic ponds. The TDS are removed in the wetlands and limestone filter ponds. In the wetlands, 60% of chloride and 40% of other contaminants are absorbed by Parthenium sp. In the limestone filter ponds, bicarbonate, calcium, magnesium and iron are removed.
