Abstract
Nok Phrao Island is given to the island by the indigenous people. It is located near the Trang estuary with several rivers flowing through. Since this island is the assembly point of different river currents, it consequently causes problems with the quality of water. This island area accumulates different pollution such as municipal and industrial pollution. This problem affects today life of the local people such as their occupation, healthy, and ecosystem. However, there are some problems which are still unsolved because of many influential factors which cannot yet be identified. In order to overcome these obstacles, mathematical models could be useful before conducting operations on the Nok Phrao Island. In this research, mathematical models were applied to assess the water quality at Nok Phrao Island by assuming observation points in the models to get a pollutant concentration before and after the implementation of biological treatment from the wastewater treatment station. The mathematical models proposed in this research could be recommended for the assessment of the standard water quality at Nok Phrao Island to account for the increase in population or growth of industries around Nok Phrao Island in the future.
