Nualgi Nano Biotechnology Approach to Remediate Eco-Symbiosis for The Conservation of Catchment Lake

Abstract

Nualgi nano biotechnology, a natural biological treatment with the idea of eco-symbiosis is proposed in this research study for an in-situ treatment of the catchment lake. Nualgi nano nutrient was dosed into a catchment lake weekly for a consecutive of 6 weeks and the catchment lake water sample was collected periodically at downstream for chemical oxygen demand (COD), biological oxygen demand (BOD), pH, total suspended solids (TSS), dissolved oxygen (DO), total nitrogen (TN), and total phosphorus (TP) analysis. DO shows an increasing trend after 6 weeks of nualgi nano biotechnology treatment, indicating an activation of diatoms with vigorous photosynthesis reaction by nualgi. However, the water quality of the catchment lake downstream water still does not meet the Class IIB National Water Quality Standard at the end of the treatment process possibly due to insufficient dose of nualgi nano nutrient in promoting fast growth of eukaryotes and heterotrophic bacteria, therefore low consumption rate of nutrients. It is suggested to prolong the application of this newly developed green and sustainable wastewater treatment approach and at higher dosage to achieve success remediation of eco-symbiosis in water body while nourishing the needs of current and future generations.
