“…An excellent fit was observed in exploratory data as the correlation coefficient of 0.995 was obtained. A similar range of fit was obtained in the work of Tamilarasan et al (2018) [50]. Based on the above points, it was proved that SAS is more effective in biohydrogen generation than control and SS.…”

The core objective of this analysis is to implement a combination of alkaline (NaOH) and sonication pretreatment techniques to produce energy-efficient biohydrogen from the marine macroalgae Chaetomorpha antennina. Anaerobic fermentation was implemented in control, sonic solubilization (SS) and sonic alkali solubilization (SAS) pretreatment for 15 days. In control, a biohydrogen production of 40 mL H2/gCOD was obtained. The sonicator intensities varied from 10% to 90% for a period of 1 h during SS pretreatment. About 2650 mg/L SCOD release with a COD solubilization of 21% was obtained at an optimum intensity of 50% in a 30 min duration, in which 119 mL H2/gCOD biohydrogen was produced in the anaerobic fermentation. SAS pretreatment was performed by varying the pH from 8 to 12 with the optimum conditions of SS where a SCOD release of 3400 mg/L, COD solubilization efficiency of 26% and a maximum biohydrogen production of 150 mL H2/gCOD was obtained at a high pH range of 11 in the fermentation. The specific energy required by SS (9000 kJ/kgTS) was comparatively higher than SAS (4500 kJ/kg TS). SAS reduced half of the energy consumption when compared to SS. Overall, SAS pretreatment was found to be energetically favorable in a field application.

This study illustrated the participation of marine macroalgae biomass (MAB) (Chaetomorphaantennina) in the liquefaction process for bioenergy production. The proposed work intended to investigate the role of disperser pretreatment (DP) and ozone disperser pretreatment (ODP) of MAB for energy efficient biogas generation. The disperser G-force of 1,613 g, pretreatment time 30 min and ozone dosage 0.00049 g O 3 /g Total solids (TS) was preferred as an optimum conditions for profitable and energy efficient liquefaction in term of soluble COD (Chemical oxygen demand) organic release. On comparing DP and ODP, the MAB liquefaction and methane production potential was much higher (20.5%, 0.20 g COD/g COD) in ODP when compared to DP (11.9%, 0.11 g COD/g COD). Therefore, the ODP essentially improve the anaerobic biodegradability of MAB. The economic assessment showed that the ODP was found to have a higher net profit of 71 United states dollar (USD)/ton of MAB compared to DP (4 USD/ton of MAB).

Surfactant induced sonic fission: an effective strategy for biohydrogen recovery from sea grass Syringodiumisoetifolium

et al. 2020

Sea grass (Syringodiumisoetifolium) is a promising source of bioenergy such as hydrogen. Due to the complex cell structure, it requires a pretreatment process prior to fermentation. This study aims to increase the biohydrogen production from sea grass by enhancing the solubilization via surfactant induced sonic fission (SSF). Initially, sonic fission (SF) pretreatment alone was carried out intherange of power from 0.02 kW to 0.18 kW for 0 minutes to 60 minutes. At the optimum condition of SF (0.14 kW, 30 minutes), ammonium dodecyl sulfate, a surfactant was added to improve the pretreatment by reducing its disintegration time period. The condition of SSF 0.14 kW (sonic power), 0.0025 g/g TS (surfactant dosage) and 11 minutes (time) was considered as optimum for effective solubilization of sea grass. The study results illustrated that highersolubilizationof 20.7% was attained through SSF when compared with SF (13.5%). Higher biohydrogen (H 2 ) production of 114(mL H 2 /g COD) was obtained in SSF when compared to SF.
