State of the Art in Anaerobic Treatment of Landfill Leachate: A Review on Integrated System, Additive Substances, and Machine Learning Application

Leachates from landfills are highly polluted with a considerable content of organic and inorganic pollutants which pose severe deterioration to environment including soil, groundwater, surface water air. Several mitigative measures have been applied for effective management leachate such as biological treatment, engineering device control migration, physical/chemical membrane technology. Among the alternatives, anaerobic digestion (AD) is promising, removal high potential renewable energy production nutrient recovery. Landfill (LFL) an excellent source substrate in AD system, its matters. The advantages disadvantages LFL were extensively discussed this review terms co-substrate, pre-treatment application, types design parameters digester. critically evaluated previous studies on treatment using system well factors can enhance efficiency, application integrated additive substances inhibition factors. Pre-treatment methods meet desired effluent quality before discharging into receiving bodies. also highlighted kinetic modelling machine learning practices, along generation LFL. Additionally, explored various strategies, recent advances LFL, suggested that there requirement further improve configuration functioning precursor selecting suitable LFL-treatment
