Abstract: This study consists of 6 experiments. 1) Study on the efficiency of the MSL systems, comprising Pak Chong clayey soil, for purifying the combined toilet and cafeteria wastewater. The mixtures of soil, kenaf or corncob, and iron scraps were filled into 15x50x100 cm acrylic boxes as blocks thus forming a brick-layer like pattern. Zeolite, sand, and limestone were used individually as the inter-layer component. The results revealed that the MSL systems comprising Pak Chong soil were effective at removing BOD5, COD, and TP with removal percentages ranging from 88 -100, 77 -99, and 76 -100, respectively. Limestone was as effective as zeolite for being used as the inter-layer component. 2) Efficiency of the 15x50x100 cm MSL systems consisting of various kinds of the inter-layer components such as zeolite, zeolitized perlite, perlite, gravel and charcoal were examined. Clayey soil was mixed with kenaf+corncob and iron scraps to form the soil mixture blocks. The results revealed that the charcoal, zeolitized perlite and perlite MSL systems were as effective as zeolite MSL system at purifying wastewater whereas gravel was inferior. 3) Efficiency of the 15x50x100 cm MSL systems comprising various kinds of organic components such as Japanese sawdust, Thai sawdust, rice straw, kenaf, and comcob were examined. Zeolite was used as the inter-layer component. The results showed that kenaf, comcob, and rice straw MSL systems were the most effective at purifying wastewater as compared with Japanese sawdust and Thai sawdust MSL systems in which often gound clogging. 4) Efficiency of the MSL system, which constructed in a 100x200x150 cm concrete box and comprised mixture of clayey soil, sawdust and iron scraps, was tested with an intermittent aeration. The rusults revealed that the operation of the MSL system with 3-day of aeration at a rate of 20 000 L m-3 d-1 alternated with 2 months of non-aeration was appropriate for maintaining the high efficiency of the MSL system on domestic wastewater treatment in Thailand. The BOD5, COD, and TP could be removed at 58-100%, 42-97%, 70-89%, and 67-92%, respectively, and the TN removal reached maximum value of 98%. 6) Efficiency of a 10-year used MSL system in Japan was evaluated with a household wastewater. The MSL system comprised the mixture of sandy soil, jute, forest floor litter, jute pellte, and iron particles. Zeolite was used as the inter-layer component. The results revealed that the MSL system at the 10th year of operation was still effective for wastewater treatment. The BOD5, COD, TN, SRP, and TP could be removed at the rates of 95.2 +- 3.8%, 79.5 +- 15.3%, 54.0 +- 27.0%, 83.1 +- 12.9%, and 82.9 +- 11.9%, respectively. 8) Soil and zeolite from a current-used MSL system and a seldom-used MSL system were characterized. The results showed high content of OM, CEC, NH4-N, NO3-N, P, Na, K, Ca, Mg, Fe and Zn in the current-used MSL system as compared with the seldom-used mSL system.
