Abstract
This research is a study of microplastic contamination in both municipal wastewater treatment systems were the Aerated Lagoon wastewater treatment system of Khon Kaen Municipality, Muang District, Khon Kaen Province, and the Stabilization Pond wastewater treatment of Udon Thani Municipality, Muang District, Udon Thani Province. The Aerated Lagoon wastewater treatment system has a microplastic treatment efficiency of 84.35%, the most common microplastic polymer was Polypropylene, equal to 62%, while the sludge samples showed that the efficiency of microplastic treatment in the sludge from the aeration pond to the sedimentation pond was 39.3%. While the Stabilization Pond wastewater system has an efficiency of treating microplastics of 77% and the most common polymer microplastics were Polypropylene was 64%, on the one hand, the sludge samples indicated that the efficiency of microplastics treatment from the aeration pond to the sedimentation pond was 29.30% and polymers of microplastics Polypropylene, the most common was 81%. Comparative the number of microplastics in water samples at aeration pond treatment and stabilization pond treatment systems at a wastewater flow rate of 35,000 m3/day. The results, number of microplastics entering the treatment system microplastics treatment and microplastic contamination to the environment for both systems are approximately related.
