Opis:: The present study focused on the phytoremediation efficiency of water hyacinth for the batik effluent treatment. Three operating factors were investigated such as retention times (0 to 28 days), batik effluent strength (20, 30 and 60%), and number of water hyacinth clumps (8, 10 and 12 clumps). The water hyacinth efficiencies was monitored through the measurement of dry weight, color, chemical oxygen demand (COD), total suspended solid (TSS), and pH. The highest efficiency of color and COD in the batik effluent treatment were achieved at day 7 with 83% (61 mg/L) and 89% (147 ADMI) removals, respectively. Both wastewater parameters were removed to below the Standard A for COD and Standard B for color. Meanwhile for TSS, the removal decreased as the batik effluent strength increased, where the highest removal (92%) was achieved at day 28 with 8 number of plant clumps. The pH was observed in range of 6 to 7. The results indicated that water hyacinth would be the best option for the low cost batik effluent treatment.

Opis:: A pressing concern of issues such as climate change has drawn main attention in the world. The burning of fossil fuels by human due to increasing energy demand in various sectors is one of the main factors that influence the climate change. This has resulted in the introduction of many renewable energy sources as alternatives to fossil fuels. Biogas is one type of renewable energy that has numerous advantages. The present review covers the recent challenges of biogas production and its conversion to electrical energy. This includes the substrates used, the operating parameters, and the pre-treatment used, which can be implemented to maximise the biogas yield. The challenges and potential of the generation of electricity from biogas were also discussed in this review. The results obtained in this review emphasise that biogas is a good renewable energy, as it solves multiple problems and at the same brings benefits to human beings in many ways.

Opis:: Currently, extra treatment of secondary effluent to remove nitrogen and phosphorous may be required for its unrestricted reuse. This can be achieved by installing the wastewater polishing systems (or tertiary treatment). The wastewater polishing solutions are environmentally friendly, cheap and effective. The experiments were conducted on a pilot scale using a Moving Bed Biofilm Reactor (MBBR) with a capacity of 500 L to polish the municipal effluent from organic pollutant, undesirable nutrients and bacteria without the use of disinfectants. The major purpose was to define and apply a model for evaluating polishing of secondary effluent and implement the optimal technology for unrestricted use. Wastewater Polishing Index (WWPI) is a new tool that has been employed for rapidly evaluating of water quality improvement. It can be implemented into any surface water effluent treatment system or for reuse. WWPI can be an important tool designed for decision makers. The total average weight of six parameters (COD, BOD₅, SS, Ammonia nitrogen, Total Phosphorus and Escherichia coli) are defined as the index, each one converted to sub-index which is scaled from zero to one hundred. If none of six parameters exist in the effluent WWPI, it is equal to zero, while if the parameters match the Malaysian’s effluent Standard B, It amounts to one hundred. In turn, WWPI is ninety when all six of them are equal to their corresponding Malaysian National Water Quality Standard (IV) for re-use. The index of wastewater polishing was validated and approved for the pilot MBBR study.

Opis:: This study aimed to assess the efficiency of Nerium oleander in removing three different metals (Cd, Cu, and Ni) from simulated wastewater using horizontal subsurface flow constructed wetland (HSSF-CW) system. The HSSF-CW pilot scale was operated at two hydraulic retention times (HRTs) of 4 and 7 days, filled with a substrate layer of sand and gravel. The results indicated that the HSSF-CW had high removal efficiency of Cd and Cu. A higher HRT (7 days) resulted in greater removal efficiency reaching up to (99.3% Cd, 99.5% Cu, 86.3% Ni) compared to 4 days. The substrate played a significant role in removal of metals due to adsorption and precipitation. The N. oleander plant also showed a good tolerance to the uptake of Cd, Cu, and Ni ions from water. The highest removal of the heavy metals indicated that the HSSF-CW would be a promising technology for heavy metal contaminated wastewater as well as in electroplating and manufacturing industries.

Opis:: Improperly treated heavy metal wastewater discharged into water sources could cause a serious issue for the environment. The aim of this study was to bioaccumulate iron (Fe) using native bacteria isolated from the laboratory drainage water containing a high concentration of iron. The experiment was conducted in 250 mL conical flasks containing 150 mL Fe solution in concentrations of 25, 100, and 250 mg/L, respectively. Approximately 10% of bacteria inoculum was cultivated in each Fe concentration for 24 and 48 hours. The results showed that Pseudomonas hibiscicola was identified as an effective iron-accumulating species of bacteria. The species could remove Fe up to 82% (25 mg/L), 77.8% (100 mg/L) and 32% (250 mg/L). This promising result indicates that the native bacteria isolated from the environment pose a great potential for the remediation of wastewater containing iron.

Opis:: Bisphenol A (BPA) is widely used in everyday life and can be found everywhere, including in the ecosystem and manufactured goods. BPA not only has a negative impact in low doses, but it also has biological and pathophysiological implications for obesity and hormonal effects. The objectives of this paper were to review the BPA removal technology and the factors that influence the BPA removal based on biological methods. BPA elimination from water is crucial for environmental protection, in terms of biological treatment. In addition, the future prospect of biological removal of BPA indicates that effective microorganism cultures could disturb the pathogen growth and increase composition rate of BPA. The biological technology by the implementation of microorganisms for the removal of BPA through break down of organic contaminants is straightforward, money saving, and widely acknowledged by the public.

Opis:: In this study, a new adsorbent derived from sunflower husk powder and coated in CuO nanoparticles (CSFH) was investigated to evaluate the simultaneous adsorption of Levofloxacin (LEV), Meropenem (MER), and Tetracycline (TEC) from an aqueous solution. Significant improvements in the adsorption capacity of the sunflower husk were identified after the powder particles had been coated in CuO nanoparticles. Kinetic data were correlated using a pseudo-second-order model, and was successful for the three antibiotics. Moreover, high compatibility was identified between the LEV, MER, and TEC, isotherm data, and the Langmuir model, which produced a better fit to suit the isotherm curves. In addition, the spontaneous and exothermic nature of the adsorption process was crucial for transforming the three antibiotics into CSFH. The greatest CSFH adsorption capacity was in MER (131.83 mg/g), followed by TEC (96.95 mg/g), and LEV (62.24 mg/g). These findings thus indicate that CSFH is one of the most effective and efficient adsorbents to use for eliminating wastewater contaminated with antibiotic residue.
