Multi Soil Layering (MSL) System for Treatment of Noodle Industry Wastewater

Abstract

Multi-soil-layering (MSL) systems consist of soil mixture layers (SML) such as charcoal, sawdust, iron scraps, volcanic soil with composition (10:10:5:75) and permeable zeolite layers (PL) were constructed in 50 cm (width) × 15 cm (depth) × 50 cm (height) an acrylic box like the brick pattern for removal of phosphate, nitrite, nitrate, oil and grease from noodle industry wastewater. The variations of the wastewater flow rate in the system were 10, 20, 40, and 80 mL min-1 with two processes aeration and non-aeration conditions were evaluated. The results revealed that the aeration assists the removal efficiency of phosphate, nitrite, nitrate, oil and grease on MSL system at flow rate 10 mLmin-1 were 99.43%, 83.65%, 79.43% and 100%, respectively
