Plant Diversity in a Constructed Wetland for Pollutant Parameter Processing on Leachate: A Review

Journal of Ecological Engineering (2021)

Isni Arliyani Bieby Voijant Tangahu Sarwoko Mangkoedihardjo

IntroductIonThe increase in urban solid waste has become a massive burden on society resulting in the environmental and economic problems, particularly in terms of poor solid waste management (Luo et al., 2020).Ninety-five percent of urban solid waste worldwide is disposed of in landfills (Gao et al., 2014).Landfills provoke several risks, as wastes may release harmful elements into the environment.The leachate from landfill remains a critical problem, because it may pose a threats to land, surface water, and groundwater (Yan et al., 2015).Factors such as area conditions, age, type of waste, and operation of the landfill can vary the content of the landfill (Fang et al., 2017).Countries with tropical climate produce more organic wastes (Idris et al., 2004).The content of organic substance in wastewater is represented by the values of Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD).The BOD and COD values are used to determine the degradation rate of landfill leachate (Barlaz et al., 2002;Borglin et al., 2004).The values of BOD/COD leachate ratio in tropical regions are 0.03-0.74higher than in other regions.In general, the BOD/ COD ratio values in tropical regions are BOD> 100 g/m 3 and COD> 500 g/m 3 in landfill leachate.Bakhshoodeh et al., (2020) showed that the content of organic substance in leachate is toxic to microbial activities.Conventional leachate processing is classified into three major groups, those are 1) chemicalphysical process, 2) biological process, and 3)

Mostly, batik industrial wastewater is produced from batik coloring process. One of this batik industry is located in Jetis, Sidoarjo since 1675. The wastewater produced from the coloring process in this location is directly dumped to Jetis river or drainage system around the area. One of the effective, efficient, and not costly wastewater treatment is by using phytotreatment process.Plants used in this research are Scirpus grossus and Iris pseudacorus. Both of this plants can grow in polluted environment and suitable to be used in wastewater treatment process. Moreover, both of these plants are semi aquatic plant that can grow in both wet and dry condition. Intermittent exposure system can be applied to increase the efficiency of the phytotreatment process for batik industry wastewater. This system connects plant and wastewater periodically through flood and drain cycle (F/D). This exposure can increase redox condition, so it can increase removal efficiency.The study variables used in this research are species variation of plants Scirpus grossus and Iris pseudacorus (single plant or combined plant) and intermittent exposure system variation, which is F/D 2:1 and F/D 1:2. The Primary parameter of this research is the concentration reduction of BOD, COD, and color. The secondary parameter such as plant morphology, wet weight, and dry weight, pH, and temperature.Preliminary research that has been done for this research is plant acclimatization and range finding test to determine the wastewater concentration. Phytotreatment test is conducted for 18 days in intermittent phase. The result shows that the best variable to remove pollutant is combined plant reactor with intermittent exposure of F/D 2:1 is able to remove 89% of COD and 97% of BOD.

Bioremediation of Oil Contaminated Soil by Biostimulation Method Using NPK Fertilizer

OALib (2017)

Bieby Voijant Tangahu Lukman Vyatrawan Rima Nurmalasari Februriyana Pirade

Petroleum contamination in the soil is known to reach the location of groundwater resources thereby potentially contaminating groundwater that is used as the primary source of clean water.Hydrocarbon compounds contained in the petroleum are also compounds that are most difficult to breakdown.One way of overcoming this problem is by bioremediation, which is a recovery of environmental condition by utilizing biological microorganism activity to reduce levels of toxicity of pollutant compounds.The research was conducted in laboratory scale for 30 days using biostimulation methods with NPK fertilizer as nutrient.Variations are done in the level of NPK fertilizer nutrients to the contaminated soil (control, 10%, and 20%).The parameters tested include the value of total petroleum hydrocarbons (TPH), temperature, pH and total microbial colonies contained in the contaminated soil samples.Results of research showed that the addition of nutrients is as much as 20% (w/w).Bioremediation was able to reduce TPH up to 4.23% (initially 8.37% TPH) in week 4 of the research.Addition of nutrition in the form of NPK fertilizer highly affects the TPH value degradation rate in oil-contaminated soil samples.Higher concentration of NPK fertilizer added leads to better degradation rate of NPH value
