Opis:: Chromium in wastewater is classified as one of the dangerous contaminants that require further treatment before being discharged to water body. The concentration of chromium in water body, especially river, has increased as many industries utilize chromium as raw material and then discharge their wastewater without any treatment. Biosorption is one of methods that are widely used to treat heavy metal containing wastewater. Bacteria are the most common microorganisms to be used as heavy metal treatment agent. Azotobacter s8, Bacillus subtilis and Pseudomonas putida had been proven to have a heavy metal resistant capability. The screening test showed that Minimum Inhibitory Concentration (MIC) value of chromium for all bacteria ranged from 100 to 250 mg/L of CrCl₃. The chromium biosorption test by bacteria showed that Azotobacter s8 was able to remove 10.53%, and Bacillus subtilis was able to remove 5.68% chromium from 50 mg/L initial concentration, while Pseudomonas putida showed no chromium removal. The chromium biosorption capacity by Azotobacter s8 was 580.08 mg/g and 349.30 mg/g for Bacillus subtilis.

Opis:: Batik is one of ethnical cultures of Indonesia. The batik production has spread throughout Indonesia. One of the batik industry areas is located in Jetis, Sidoarjo, Indonesia. This industry has been operating for approximately 350 years without processing its wastewater. The batik wastewater contains several toxic compounds such as high BOD, COD and color pigment. These compounds can be harmful for the environment if discharged directly to water bodies. Phyto-treatment might be a solution to overcome this problem. The use of Scirpus grossus and Iris pseudacorus with variations of waste irrigation system using the intermittent method showed a COD removal up to 89% and BOD removal up to 97%. Mixed culture of S. grossus and I. pseudacorus showed a better removal than its single culture. The highest removal of BOD and COD was obtained in reactor with mixed culture plants under Flood/Drain ratio of 2:1.

Opis:: Seashells waste is abundant in coastal area, especially in the locations where fisheries are a major occupation. This abundant resource of seashells opens a new opportunity further utilization. Seashells waste is a source of CaCO3, which may be converted into CaO via the calcination process. This study analyzed the characteristics of the CaO produced via calcination process at different temperature and calcination time. The calcination process was carried out at a temperature of 800°C, 900°C, and 1000°C with variation of 2, 3, and 4 hours in time. The Fourier transform infrared spectroscopy (FTIR) result showed that the spectrum of 2513 cm-1 as an indication of the C-H group containing CaO appearing after calcination. The FTIR results suggest that the calcination time did not gave major alteration to the functional groups. The results of X-ray diffraction (XRD) analysis showed that CaO laid at the angle of 58.1° and 64.6°. Scanning Electron Microscopy–Energy Dispersive X-Ray Spectroscopy (SEM-EDS) results showed that the most significant compositional outcome after the calcination process was Ca and O at all temperatures and calcination times. All calcined seashells showed rough surface and irregular shape particles. The result of a Thermogravimetric analysis (TGA) suggested that the highest mass alteration occurred at a temperature of 800°C with 78 mins of calcination time.

phytoremediation
Opis:: Phytoremediation is considered of a cost effective and environmentally friendly technology and has been used successfully for the remediation of soils and water contaminated with various pollutants. Specifically for full scale application to treat industrial wastewater, phytoremediation is used as sole technology for different types of wetlands. However, phytoremediation of polluted water in wetland type reactor has been mostly studied as black box. The method to measure the performance is only based on pollutant removal efficiency and there is very limited information available about of the pollutant removal mechanisms and process dynamics in these systems. Thus, the aim of this chapter was to briefly review basic processes of phytoremediation, its mechanisms and parameters, and its interaction between rhizo-remediation and microbe-plant. In addition, this chapter also elaborated phytoremediation challenges and strategies for full-scale application, its techniques to remove both organic and inorganic contaminants by aquatic plants in water, and some examples of applications in industries.

Opis:: This research aimed to investigate the optimum conditions of slow sand filter (SSF) media modification by using ground Anadara granosa shell waste and the effect of the ripening period on the total coliform (TC) removal efficiency. The response surface methodology with the central composite design was conducted with three factors, namely, seeding time (2–3 weeks), running time (0–20 days), type of SSF media (i.e., river sand, A. granosa shell, and their combination), as independent variables. The results showed that the ripening period factor interacted insignificantly by improving the TC removal efficiency due to short ripening time (p > 0.05). The optimum conditions of the SSF to achieve maximum TC removal efficiency (99.70 ± 21.50%) were as follows: combination media of river sand and ground A. granosa shell waste, 2.8 weeks (20 days) of ripening period, and 20 days of operation. In conclusion, the optimum operating parameters of the slow sand filter revealed that the combination of river sand and A. granosa shell as well as prolonged ripening and running times could increase the removal efficiency of TC. Hence, the A. granosa shell has good application potential as filter media to remove TC from the municipal wastewater.
