Abstract

Saguling reservoir is an artificial reservoir located in West Bandung regency at an altitude of 643 m above sea level and serves to stem the Citarum River which is the largest river in West Java. Upper Citarum River has detected the organochlorine insecticide, one of them iss DDT. It is feared that DDT can accumulate in Saguling Reservoir which is the first dam to stem the Citarum River. This is very worrying given Saguling has greatly affect to the lives of many people. This study was conducted to estimate the fugacityvalue and concentration of DDT in each environmental compartment, such as in water, sediment, fish, aquatic plants, and mollusks by using Fugacity models. From calculation result, average DDT fugacity in the air is 3.23.10-14Pa, on the soil 2.73.10-17Pa, in the water 1.78.10-9 Pa, in sediments 9.64.10-10Pa. DDT concentration in the air compartment at Saguling Reservoir is 9,1.10-12ppm, on the ground 4,5.10-11ppm, in the water 6,9.10-4ppm, in sediments 0.99ppm, in the fish 0.013ppm, in the aquatic plant 0.005ppm, and in the mollusk 0.002ppm. Fugacity models are useful in predicting the distribution of DDT in each environmental compartment in Saguling Reservoir.

Abstract

The purpose of this research was measuring the treatment efficiency, determining the optimum operating conditions, determining the criteria for water reuse. This research is conducted in the laboratory using a constructed wetland with type of plant is Typha latifolia. Variations are made in this study are detention time (1day, 3days and 5 days) and type of reactors (constructed wetland & aerated constructed weland). Each reactor is given wastewater feed derived from effluent of WWTP Bojongsoang. The research was a sequenced of previuos reserach ( Panelin 2016). Parameters examined in this study are COD, NTK, Nitrate, Nitrite, Ammonium, pH, and temperature. Measurement of COD, pH, and temperature are conducted every day, while  NTK NTK, Nitrate, Nitrite,and Ammonium are done after the reactor reaching steady state conditions. Based on the measurements, the best pollutant elimination occurs on detention time of 5 days. The Nitrite pollutant removal efficiency is 96.7%. Ammonium pollutant removal efficiency is 89.1%. NTK pollutant removal efficiency is 86.2% . Constructed wetland reactor with additional aeration can remove nitrogen parameters better than the reactor without additional aeration.
