eng	The Use of Submerged Hollow Fiber Microfiltration in Treatment of Landfill Leachate	The contribution is focused on the study of pretreatment of leachate from municipal waste landfill using submerged hollow fiber dead-end microfiltration combined with zeolite addition. This is an effective method to eliminate colloids, suspended matter, and even some soluble ions from waste waters. Influence of wastewater pretreatment and process parameters (such as pH and zeolite amount) on microfiltration filterability was monitored experimentally. The results indicate that it was advantageous to reduce the pH into the acidic range. Under these conditions precipitated certain high molecular weight organic molecules such as humic and fulvic acids, responsible for irreversible RO and/or IE membrane fouling. The zeolite addition to the feed mixture also had a positive effect; minimally more permeable secondary membrane was created on the surface of individual membrane fibers.
