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.

Daily industrial activities pose a significant risk of environmental contamination through the release toxic chemicals, including heavy metals, radionuclides and organic pollutants. Coastal marine areas, estuaries harbors serve as primary hotspots for such pollution, with sediments acting ultimate sink urban discharges, posing serious problem. Addressing this pressing issue requires adoption environmentally friendly technologies remediation recovery contaminated sediments. This paper provides comprehensive review different approaches sediments, focusing on principle electrokinetic remediation, special emphasis use microorganisms. A bibliometric analysis key articles in field is presented to elucidate most important findings, particularly environment. The current state-of-the-art reported soil sediment approaches, first large-scale experiments preliminary cost estimate reported. However, limited information available applicability these techniques environment highlighted. limitations risks associated an inadequate implementation technique are discussed while acknowledging advantages it offers situ environments.

This study investigates the impact of Electrokinetic Remediation (EKR) time on total petroleum hydrocarbons (TPH) removal from soil, focusing electroosmotic phenomena guided by Helmholtz-Smoluchowski theory. Soil samples were exposed to a constant 2 V/cm voltage gradient for 8, 16, and 24 hours, utilizing 0.05 M Na SO 4 solution as an electrolyte enhance soil conductivity. Biostimulation was combined with EKR, TPH levels microbial colonies (TPC) monitored over 4-week period. Maintaining optimal conditions (25-40°C, pH 6-8, 30-60% water content) crucial effective biodegradation. Results showed that 24-hour EKR duration most effective, achieving 87.9% rate. The 16-hour closely followed at 85.7%, while 8-hour exhibited lower effectiveness 62.5%. TPC counts increased in fourth week durations but decreased duration. Post-EKR, gradual decline indicated flow’s (EOF) positive desorption Electroosmosis influence evident varying concentrations among segments after higher near cathode durations. Lower variation suggested electroosmosis-induced desorption, reduced regions A (near anode) B (middle) resulted biodegradation mobility due electrophoresis. Confirmation electroosmosis across all supported observed content EOF volume. highest proportion chamber 22.2%, 16 hours 16.1%, 8 8.6%.
