NARRATIVE REVIEW: MICROPLASTIC SAMPLING TECHNIQUE IN LEACHATE TREATMENT PLANT BASED ON APPROACH OF WWTP MICROPLASTIC SAMPLING TECHNIQUE

Abstract

Landfill solid waste composition 21-42% is plastic waste potentially as a microplastic source because of the extreme environments. The abundance of microplastics from waste degradation can be discovered inside leachate in a Leachate Treatment Plant (LTP). The compatibility of the sampling technique supports knowing the effects of LTP into representatively microplastic concentration. The article review aims to understand the similarity characteristic between a LTP and a Wastewater Treatment Plant (WWTP) and to know the microplastic sampling technique in a LTP with an approach of microplastic sampling technique in a WWTP. The characteristic comparison between both showing three similarities is that the waste being treated is a type of wastewater, parameters of treated liquid waste to meet the quality standard, and both of them include secondary treatment and advanced treatment. Therefore, the microplastic sampling technique in LTP can be approached by WWTP’s microplastic sampling technique. Microplastic sampling technique in LTP tent to several factors, such as sample type and volume which is determined by sampling point, sampling method looks from the homogeneity of sampling point, sampling tool adjusted kind of sample in the LTP, sampling point based on the purpose of sampling, and two times minimum of sampling time and sampling replication.
