Abstract

Water is important for all living organisms and is the fundamental element in all processes such as energy production, food production, or environmental management. Water demand is very high and will keep increasing due to the continuous growth of the number of populations. When the population grows, environmental problems continue to rise and It is also due to harmful human acts that drain natural resources and destroy the environment. When nutrients that cause eutrophication are mixed with bodies of water, it can be harmful to aquatic animals. These nutrients can also cause harm to human health through various diseases. Groundwater being exposed to excessive nitrate can resort to it being undrinkable. The primary objective of this thesis paper is to be able to analyze the efficiency of a modified constructed wetland system using Helianthus annuus L. in the removal of Nitrogen, Phosphorous, and Ammonia from septic tank effluents with the use of HF-VF Baffle Hybrid Flow Constructed Wetland. This research will also investigate if the water quality parameter passed to DENR Administrative Order 2016-08 (DAO 2016-08). The removal results were obtained using SubWet Software modeling, the following efficiency removal rate was obtained: 99.89%, 92.61%, 97.10%, 97.70%, 55.37%, 95.07% for BOD5, COD, TSS, TP, N, NH4, respectively. Results of having a hybrid horizontal and vertical flow wetland are effective in the removal of Nitrogen, Phosphorus and Ammonia in the wastewater coming from the fish farm and suggested that the most active sites for nitrification and denitrification were separated spatially in a wetland
