Organic and trace organic performance data for ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) at the Lake Arrowhead water reclamation pilot plant are analyzed to determine the treatment efficiency of these processes in an indirect potable reuse design. Four organic parameters were studied: dissolved organic carbon (DOC), ultra-violet absorbance at 254 nm (UV-254), SUVA and base neutral analysis (BNA). UF and NF removed the larger compounds from the influent, but had no significant impact on the base neutral fraction with the exception of sterols. The RO process removed DOC and UV-absorbance compounds from the effluent to their respective detection limits. Base neutral compounds were significantly removed by RO, leaving at extremely low concentrations small molecular weight compounds, indicating indirect potable reuse is technically feasible.

Leachate Pollution Index

The improper treatment of landfill leachates is one of the major problems associated with waste landfilling and causes serious environmental pollution at waste landfill sites and their surroundings. To develop a suitable landfill leachate treatment system and to minimize the risk of environmental pollution, it is important to characterize seasonal and temporal variations of landfill leachates. This study investigated the leachate quality of the Nam Son waste landfill in Hanoi, Vietnam in 2017–2019 and characterized the potential risks of landfill leachate using a leachate pollution index (LPI). The results of this study showed that the seasonal and temporal variation of the overall LPI during the monitoring period was small and in the range of 20–25 (values 2.5 times higher than the maximum permissible limits of Vietnam National Technical Regulation on Industrial Wastewater). The LPI sub-indices attributed to organic and inorganic pollutants were major components of the LPI. Especially, the annually averaged values of LPI of inorganic pollutants were 7.7 times higher than the maximum permissible limits, suggesting that the treatment of inorganic pollutants, such as ammonium-nitrogen (NH4+–N) and total nitrogen (TN), is highly required at Nam Son landfill to prevent environmental pollution surrounding the landfill site.

Treatment Procedures

In this study we have in pilot scale tested different methods for treatment of leachate from amunicipal solid waste (MSW) landfill, Only to focus on sum parameters, nutrients and metalswhen designing treatment methodology for landfill leachate is not enough, it is also importantto measure the content of toxic organic compounds in low concentrations, However, it is notpractical to analyse all substances in the leachate and for making evaluation of treatmentsfeasible our own analytical protocol was created, The efficiency of tested treatmentprocedures was evaluated by measuring changes in concentrations of a number of chosenparameters and organic compounds before and after treatment The treatment methods testedthat showed the highest efficiency towards organic pollutants in leachate were ozonetreatment and chemical oxidation with Fenton's reagent However, more natural basedmethods like filtering the leachate through a bed with peat mixed with carbon containingbottom-ash showed promising results.

Before And After

Landfill Leachates is one of the pollutants containing high organic matter and heavy metal which can cause toxic pollution to water due to less than optimal leachate processing. This study aims to introduce fine bubbles treatment to the leachate processing technology at the waste treatment facility at Sarimukti, West Java Indonesia. The toxicity test was conducted in the acute toxicity test and test for D. magna. The acute toxicity test was carried out using a static biological test according to APHA standards (1995). The LC50-48 hours ware calculates using the Finney Probit Analysis Software. The results showed that the effectiveness of Sarimukti TPA leachate treatment was 97.5% DO, 71% BOD, 86% TDS, and 74.8% turbidity. The XRF spectra on the leachate after fine bubble found a recovery of heavy metal elements such as Cr, Mn, Fe, Zn, Cu, Pb, As, and Sn. Based on the Minister of Environment and Forestry Regulation, the effectiveness of leachate processing has reached the safe standard limit for pH, mercury, cadmium parameters. The acute toxicity of leachate before and after treatment fine bubble was 14.516 ppm and 11.178 ppm. The acute toxicity of leachate is considered almost non-toxic.

Leachate is a complex liquid that is often produced from landfills, and it contains hazardous substances that may endanger the surrounding environment if ineffectively treated. In this work, four leachate treatment applications were examined: combined leachate/palm oil mill effluent (POME) (LP), leachate/tannin (LT), pre-(leachate/tannin) followed by post-(leachate/POME) (LT/LP), and pre-(leachate/POME) followed by post-(leachate/tannin) (LP/LT). The aim of this work is to evaluate and compare the performance of these treatment applications in terms of optimizing the physicochemical parameters and removing heavy metals from the leachate. The highest efficiency for the optimization of the most targeted physicochemical parameters and the removal of heavy metals was with the LP/LT process. The results are indicative of three clusters. The first cluster involves raw leachate (cluster 1), the second contains LP and LP/LT (cluster 2), and the third also consists of two treatment applications, namely, LT and LT/LP (cluster 3). The results demonstrate that LP/LT is the most appropriate method for leachate treatment using low-cost agro-industrial materials.
