The objective of this study was to investigate the effect of municipal wastewater treatment system on species diversity and density of phytoplankton in mangrove forest in front of the Royal LERD Project compared with a reference mangrove. The effluent from the Royal LERD Project was collected and dissolve oxygen (DO), biochemical demand (BOD), total solid (TS), and phytoplankton were monitored during May 2016 to April 2017. The results reveal that the mean value of DO, BOD, and TS of effluent in the experiment and reference mangrove were significant different while the species diversity and density of phytoplankton of both mangroves were not significantly different. Therefore, wastewater from the municipal wastewater treatment system of the Royal LERD Project does not have an effect on species diversity and density of phytoplankton in mangrove forest in front of the Royal LERD Project.
