As part of a comprehensive evaluation of post-treatment techniques for the removal of chemical and microbiological pollutants from lagoon effluents, an aerated biofilter was designed. The main objective of this study was to evaluate the performance of pozzolan and Luffa cylindrica as low-cost packing materials for the advanced treatment of Stidia natural lagoon effluent. The aerated biofilter operates in down-flow with HLRs of 11.37 to 28.43 m 3 m −2 d −1 and an air/liquid flow ratio of 3 : 1. The different experiments performed on the pilot showed that the percentages of sCOD removal vary with the HLRs and the wastewater concentration at the biofilter inlet. In this study, sCOD removal efficiencies above 78.9 % were achieved depending on HLR, and a maximum removal efficiency of TSS of 71.5 % was obtained for 28.43 m 3 m −2 d −1 . At low HLR (11.37 m 3 m −2 d −1 ), the treated effluent had the following average concentrations: sCOD of 29.5 mg l −1 , BOD 5 of 21.7 mg l −1 and TSS of 26.4 mg l −1 . These experimental results were used with an empirical model to determine the media constant n and treatability factor K. The faecal coliforms and Escherichia coli detected in the treated effluent were less than 10 5 CFU/100 ml, which meet the national guidelines for wastewater reuse in irrigation.

“…The modification of the fibers was done using NaOH. The fibers were first soaked in distilled water for 24 h then in 0.5 M NaOH solution for another 2 h. NaOH helps to improve the wettability and hydrophilicity of the fibers [14,16]. It was also done to improve the rigidity and toughness of the fiber to help them retain their comb-like porous macrostructure during operation as a packing material [17,18].…”

Asa River is of strategic importance to the citizens of Ilorin, Nigeria, because it meets the basic water needs of the community and its surroundings. The river is however polluted and requires some form of treatment before it can be used. The aim of this study was to investigate the performance of a Luffa cylindrica biomass packed bed for the remediation of color and biochemical oxygen demand (BOD) and the pH regulation of Asa river water. The fibers were characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS). FTIR modification only led to slight changes in the functional groups of the fibers. EDS revealed some changes in the fiber composition due to NaOH modification. The inorganics present were all less than 5% (except for calcium in the modified fibers). SEM revealed a very plain surface of the fibers. The color was reduced from 9.88 to 4.7 TCU and 4.37 TCU for the unmodified and modified fibers respectively after 2 h. Both fiber types were able to effectively regulate the pH to the acceptable 6.5-8.5 threshold after 2 h. The BOD was reduced from 3.7 to 2.8 mg/L and 1.7 mg/L for the unmodified and modified fibers respectively after 2 h. Both color and pH were reduced below WHO permissible limit by the current set-up. Fiber modification improved the packed bed performance for color and BOD reduction.

“…The extraction of fiber from Luffa fruit is simple and the tensile strength of these fibers ranging between 10 to 30 MPa. [ 23 ] Parida et al [ 24 ] reported the polymer composites reinforced with Luffa fruit inner core fiber as reinforcement and found that these composites having sufficient mechanical strengths and can withstand the thermal stability beyond 300°C. The similar experiments were conducted on sponge gourd fiber reinforced epoxy composites by Mani et al [ 25 ] and seen in improved mechanical as well as thermal behaviors.…”

The aim of this investigation is to determine the physical, mechanical, water absorption behavior, and thermal properties of Tamarindus indica seed powder (TISP) incorporated Luffa cylindrica fruit (LCF) waste fiber reinforced epoxy composites. TISP of size 40–50 nm was mixed with matrix in various weight proportions (2.5, 5.0, 7.5, and 10 wt%), and the composite laminates were made using the manual stacking followed by compression molding technique. The developed composite samples were subjected to various testing which includes density, tensile, compression, flexural, impact, hardness, and water absorption behavior. Thermo‐gravimetric analysis (TGA) was also done to investigate the influence of TISP addition on the prepared sample to determine thermal stability. The results showed inclusion of 7.5 wt% TISP resulting better physico‐mechanical and thermal properties. A field emission scanning electron microscopy (FESEM) test was conducted for the investigation of the bonding nature at the fiber/matrix interface, fiber pull‐outs, voids, and internal cracks. From the results it is seen that the addition of TISP improve the performance of the developed LCF waste fiber reinforced epoxy composites. Further, these composites show better resistance to moisture, which could have implications in automobile and structural applications.
