“…The average value of J V throughout the entire permeation test was 96.1 L/ (m 2 h) in direct fine-UF; this value dropped to 9.3 and 8.4 L/(m 2 h) after PAC adsorption (Table 3). The other results were obtained by Renou et al (2009) on UF (cutoffs of the membranes between 50 and 1 kDa) for the raw leachate filtration. The membrane productivities were not satisfactory (55-60 L/(m 2 h)), but were improved by pre-treatment with lime addition.…”

“…According to Bohdziewicz et al (2001), 50% of the organic substances from landfill leachate could be rejected by UF alone. In a study by Renou et al (2009) with UF membranes, the reduction of COD was from 38% (cutoff of 50 kDa) to 66% (cutoff of 1 kDa) from raw leachate.…”

“…Three KERASEP membranes were used: 1, 5 and 15 kDa MWCO. The removal of COD was 66%, 63% and 47%, respectively [105]. Trebouet MPT-20 reduced the COD, BOD and SS by 74%, 85% and 100%, respectively.…”

“…Given the conditions of neutralising impurities therein, especially important is the dynamics of the composition and concentration of organic substances, since the amount of biodegradable compounds decreases and the amount of compounds that are difficult to degrade increases as the landfill ages. There are numerous methods involving effective treatment of leachates at municipal waste landfill sites (Renou et al 2009). These include the physicochemical methods, such as volume reduction by means of ultrafiltration and reverse osmosis , or a combination of these methods.…”
