Wastewater treatment using combination of stainless steel membrane and adsorption system

摘要

A fabricate design of combination membrane filtration and absorption system was used to treat palm oil waste to comply with standard B in regulation of environment act, 1974. This systems as adopted was found to be an efficient method to remove parameters in palm oil waste. The parameters that involves in this study are BOD (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand), pH, TDS (Total Dissolve Solid) and turbidity. From this experiment, the comparison effectiveness between only using membrane filtration and using a combination of stainless steel membrane (membrane filtration) with adsorption columns (adsorption system) can be proven. The adsorbents used in the columns were activated carbon, activated alumina, rice husk and wood waste. The best types of adsorption columns can be determine from this experiment. The columns having a diameter of 6 cm with bed depth 500 cm could treat COD and BOD at average 81.3 % and 79.55%. Effect of flow rate, blank concentration and amount adsorb were studied
