“…Brewery wastewater shows a COD of 1500-5000 mgO 2 /L and a BOD 5 of 1000-3000 mg/L [30]. Batik wastewater contains both coloring and wax removal wastewater, wherein the BOD 5 values are 261.25 mg/L and 8126 mg/L, respectively [32]. The BOD is 3300 mg/L and 500 mg/L in the case of leather effluents and textile effluents, respectively.…”

Reliability of Biodegradation Measurements for Inhibitive Industrial Wastewaters

Industrial wastewaters may contain toxic or highly inhibitive compounds, which makes the measurement of biological oxygen demand (BOD) challenging. Due to the high concentration of organic compounds within them, industrial wastewater samples must be diluted to perform BOD measurements. This study focused on determining the reliability of wastewater BOD measurement using two different types of industrial wastewater, namely pharmaceutical wastewater containing a total organic carbon (TOC) value of 34,000 mg(C)/L and industrial paper manufacturing wastewater containing a corresponding TOC value of 30 mg(C)/L. Both manometric respirometry and the closed-bottle method were used in the study, and the results were compared. It was found that the dilution wastewaters containing inhibitive compounds affected BOD values, which increased due to the decreased inhibiting effect of wastewater pollutants. Therefore, the correct BOD for effluents should be measured from undiluted samples, while the diluted value is appropriate for determining the maximum value for biodegradable organic material in the effluent. The accuracy of the results from the blank samples was also examined, and it was found that the readings of these were different to those from the samples. Therefore, the blank value that must be subtracted may differ depending on the sample.

“…The COD value represents the amount of oxygen needed to oxidise organic substances in wastewater through chemical reactions. This chemical reaction will convert organic substances into CO2 and H2O (Tangahu and Putri, 2017). Similar to BOD value, a decrease in COD value in wastewater indicates that wastewater will have a lower negative impact on the environment (Alkimin et al, 2019).…”

This study aims to explore the potential of using Napier grass (Pennisetum purpureum) as a low-cost alternative for treating wastewater contaminated with chromium (Cr) in the tannery industry. Traditional chemical treatment processes are costly, leading to many industries not committing to treatment. Phytoremediation, the use of plants to remove contaminants from the environment, could be a viable solution. The study conducted an experiment to test the tolerance and effectiveness of P. purpureum in treating wastewater containing Cr(VI) at concentrations of 20 ppm, 40 ppm, and tannery wastewater. The plant was grown in a constructed wetland pond using a batch system for 31 days. The results indicate that P. purpureum can survive and grow well in all treatments, showing tolerance to Cr. The plant's phytoremediation capacity was effective at 20 ppm of Cr(VI) as demonstrated by the chemical and physical characteristics of the medium (BOD, COD, pH, and TDS). The plant was able to remove a significant amount of total Cr and Cr(VI), with removal capacity ranging from 71.79% to 99.96%. The translocation factor (TF) for Cr in the roots was less than one, indicating that the plant has the potential to be used as a phytoremediator for Cr by accumulating it in its roots.

“…The decreasing of COD in the phytoremediation process of Batik wastewater was a time consuming and the removal efficiency was depending on the plant used in the study. For example, degradation of COD using Egeria densa and Salvinia molesta achieved 95% and 99% respectively for the 17 days process [29]. Therefore, the electro-assisted system aimed to extend the phytoremediation process on the removal of organic matter could simultaneously decrease the heavy metal concentration in the Batik wastewater [30].…”

The aims of the study are to identify the effectiveness of wastewater treatment from the Batik industry using a simultaneous of electrocoagulation (EC) and electro-assisted phytoremediation (EAPR). Rough horsetail (Equisetum hyemale) was used as an accumulator plant in the EAPR system. Electrocoagulation was conducted for 1 h at a constant voltage of 20 V in 10 L solution, while EAPR was processed for 7 day at a constant voltage of 5 V in 17 L solution. The chemical oxygen demand (COD) of water was determined by closed reflux of colorimetric methods and heavy metal concentration was determined by flame-atomic absorption spectrophotometer. The results showed that the COD decreased by 69.6% after 1 h of electrocoagulation process and up to 80.9% after the EAPR process. The concentration of Cr and Pb decreased as much as 25% and 8.52%, respectively in the similar process. The simultaneous process could extend the heavy metal removal up to 0.28 mg/L for Cr and 0.09 mg/L for Pb in liquid wastewater from the initial concentration. These results showed that the levels of COD and heavy metal concentration in Batik wastewater have reduced in accordance with the Ministry of Environment Decree No. 5/2014 Republic of Indonesia regarding various industries wastewater standard with the threshold limit of 150 mg/L for COD and 1.0 mg/L for Cr on textile industry and 0.1 mg/L for Pb on Class I for another wastewater standard. The estimated cost of operation was US$ 1.509 m–3 indicating the viability of Batik industry wastewater treatment.
