Bioaugmentation and vermicompost facilitated the hydrocarbon bioremediation: scaling up from lab to field for petroleum-contaminated soils

Environmental Science and Pollution Research, Journal Year: 2024, Volume and Issue: unknown

Published: March 22, 2024

Abstract The biodegradation of total petroleum hydrocarbon (TPH) in soil is very challenging due to the complex recalcitrant nature hydrocarbon, hydrophobicity, indigenous microbial adaptation and competition, harsh environmental conditions. This work further confirmed that limited natural attenuation hydrocarbons (TPHs) (15% removal) necessitates efficient bioremediation strategies. Hence, a scaling-up experiment for testing optimizing use biopiles TPH polluted soils was conducted with three 500-kg pilots soil, respective treatments were implemented: including control (CT), bioaugmentation vermicompost treatment (BAVC), combined application BAVC along bioelectrochemical snorkels (BESBAVC), all maintained at 40% field capacity. study identified pilot scale level, successful can achieve 90.3% removal after 90 days. BAVC’s effectiveness stemmed from synergistic mechanisms. Introduced consortia capable degradation, while provided essential nutrients, enhanced aeration, and, potentially, acted as biosorbent. it be concluded significantly enhances compared attenuation. While snorkel (BES) also showed significant removal, did not differ statistically individual BAVC, under applied Further research needed optimize BES integration broader applicability. demonstrates scalable mechanistically sound approach soil.

Reverse Polarity-Based Soil Electrokinetic Remediation: A Comprehensive Review of the Published Data during the Past 31 Years (1993–2023)

ChemEngineering, Journal Year: 2024, Volume and Issue: 8(4), P. 82 - 82

Published: Aug. 15, 2024

Soil restoration by exploiting the principles and basics of electrokinetic (EK) has been extended to involve several categories, such as remediation in soil (SEKR), consolidation, prevention pollution, reclaiming salt-affected soil, dewatering/dryness wet soils, water reuse, seed germination, sedimentation, etc. As an extension our recently published review articles on (SEK) process intensification/optimization, present illustrates effect a reverse-polarity mode (RPM) efficiency SEK. Based searches six database search engines, we did not find any relevant reviews focused SEK improvements using RPM. The influences RPM are described various features, including (a) pollutant removal (organic, inorganic, mixed pollutants) (b) integration with other processes (phyto/bioremediation Fenton oxidation), geosynthetics (consolidation, stabilization, sedimentation), operation conditions, properties. Most studies have organic pollutants. Several benefits can be gained from applying RPM, controlling soil’s temperature, pH, moisture values at desirable levels, reducing large number chemical additives, (c) high efficiency, (d) maintaining indigenous fungal community’s appropriate diversity abundance, (e) stable higher electric current, (f) enhancing microbial growth, However, hindrances electroosmosis flow, relatively energy consumption, microbes prolonged experiment period, providing oxygen for community that may anaerobic bacteria, Finally, is considered important improving performance SEK, according experimental endeavors.

Utilizing the approaching/movement electrodes for optimizing the soil electrokinetic remediation: A comprehensive review

South African Journal of Chemical Engineering, Journal Year: 2024, Volume and Issue: 50, P. 75 - 88

Published: July 14, 2024

Applying soil electrokinetic remediation (SEKR) is considered a valuable technique to remediate contaminants-containing low permeability soils with the advantage of integration other approaches (e.g., chemical, physical, and biological). The basics principles (EKR) were utilized in different fields interest; for example, sedimentation, seed germination, consolidation, dewatering, etc. present review focused on role electrode approaching/movement (EAMT) improving effectiveness SEKR. Based our search collected literature, influence EAMT efficiency yielded no pertinent reviews. We looked articles relevant six engines, chosen based data mentioned materials methods section. Our objective was illustrate proper applicability from perspectives overcome some obstacles reported traditional effect discussed/illustrated four including a) approaching/moving anode (AMAT), b) cathode (AMCT), c) electrodes placement/gap, d) continuously reoriented/rotating, reciprocating, rotational electric fields. Several advantages could be gained application current passing, pH reduction, increasing heavy metals desorption, elevating redox potential, e) reducing energy consumption, f) removal percentages contaminants, g) extra chemical additives or modifications, h) enhancing electroosmotic flow, i) installing auxiliary presents more stable uniform field, j) ultimately environmental risks metals. Two proposed practical applications (in-situ ex-situ). Although there are various achieved EMAT, published research during past 31 years (1993–2023) few compared enhancement approaches.

Plant Microbial Fuel Cells (PMFCs) are bioelectrochemical systems able to convert solar energy into bioelectricity with the support of rhizosphere microbial populations. The simultaneous and biomass production makes PMFCs an interesting nature-based solution for promoting not only production, but also soil decontamination. This review reports main bacterial groups involved in fuel cell key factors influencing their performances plant presence. In detail, implement remediation contaminated soils, it is firstly necessary know chemical characteristics pollutants, concentrations, physico-chemical community structure functioning. Then, based on characterization data soil, a species resist pollutant toxicity promote phytoremediation processes (e.g. phyto-extraction, phyto-stabilization, phyto-degradation) can be selected, climatic study area. Finally, electrode materials configurations need designed ensure efficient growth, adequate electron transfer best possible generation at same time degradative activity microorganisms.
