Abstract

aboratory wastewater is produced through laboratory activities. Laboratory wastewater can have a large impact on the environment if it is not processed before being discharged into the water body. Laboratory waste treatment can be carried out using suspended growth technology to reduce pollutant loads, especially Biological Oxygen Demand (BOD5) and Chemical Oxygen Demand (COD). Aims: This study aims to treat wastewater produced by the activity of laboratory using suspended growth technology. Methodology and Results: This research was conducted by finding the most efficient rotor rotation in degrading the load of BOD5 and COD pollutants. The reactor used is a Mixed Flow Reactor type reactor made of acrylic material with a thickness of 5.5 mm. The reactor is arranged into three series with the same sampling time and different rotor turns that expressed in rotors per minute (rpm). The reactor series consists of Reactor I with 50 rpm rotor rotation speed, 100 rpm Reactor II and 150 rpm Reactor III. Processing is carried out using 8 hours of detention time and variation of sampling time every 8 hours. Conclusion, significant and impact study: From the results of the study obtained the highest level of effectiveness of reducing pollutant load on processing using 150 rpm rotor rotation and 40 hours sampling time which is 94.6% for BOD5 parameters and 94.4% for COD parameters.

Abstract

Untreated domestic wastewater can pollute the aquatic ecosystem. Vermifilter integrated with the Canna indica plant is one of the technological alternatives that can be used to treat domestic wastewater. One of affecting the performance of vermifilters is the vermibed media. Aim: This study aims to examine the effect of vermibed material on the concentration of COD, TP, DO, and the pH value of domestic wastewater treated with vermifilter combined with Canna indica plants. Methodology and Results: The research was conducted on a laboratory scale with a a continuous system using a plastic reactor dimension of 59 x 38 x 29 cm, which is filled with sand filter media, coconut fiber, gravel, and vermibed. The vermibed reactor consists of 4 reactors including reactor 1 (R1) vegetable vermibed, reactor 2 (R2) sawdust, reactor 3 (R3) banana peel, and reactor 4 (R4) cow dung. The results showed that  at the end of the research, the best performance is showed by reactor R2 that able to decrease COD 94.81%, TP 92.07%, DO increase 320.00%, pH 6.30±0.10.  Vermibed sawdust (R2) can lower COD, TP and raise DO higher to treat domestic wastewater by combining vermifilter with Canna indica plant.  Conclusion, significance, and impact study:  Vermifilter with Canna indica plant is an effective wastewater treatment in reducing COD, TP, increasing DO and pH value.   This treatment is easy processing of operation and maintenance, does not require large land, can be done on an individual scale, and is environmentally friendly.
