In this study, polyethylene and zeolite, as media in two-stage biological aerated filters (BAF), were evaluated for simultaneous removal of ammonia nitrogen organics micro-polluted water under low temperature conditions. For specific source water, the contaminants characteristics are by single-factor experiment to determine suitable pH, air-water ratio (AWR) hydraulic load (HLR). Ammonia perman...

Abstract The palm trees as non-timber forest plants have long been cultivated by farmers in Indonesia. This plant produces sap which can be released through the tapping process. is very easy to decrease quality since tapping. indicators of that are commonly used pH (pouvoir Hydrogene) and color. Therefore, this study aimed analyze parameter color sample was obtained from market traditional Mata...
