BTEX Remediation
Hepure provides chemical oxidation and bioremediation products for treatment of benzene, toluene, ethylbenzene, and xylenes (BTEX) in soil and groundwater.
About BTEX Contamination
BTEX compounds — benzene, toluene, ethylbenzene, and xylenes — are petroleum-derived contaminants commonly found at fuel stations, petroleum storage facilities, refineries, and industrial sites. These volatile organic compounds are components of gasoline and other petroleum products. Benzene in particular is a known carcinogen and is subject to stringent regulatory standards in groundwater.
Chemical Oxidation (ISCO)
Sodium persulfate and hydrogen peroxide are chemical oxidants used for BTEX compounds in groundwater and soil. Technology selection should be based on site conditions, contaminant concentrations, and oxidant demand.
Enhanced Bioremediation
BTEX compounds are readily biodegradable under both aerobic and anaerobic conditions. Calcium peroxide provides slow-release oxygen to enhance aerobic degradation. For anaerobic treatment, emulsified vegetable oil and sodium lactate serve as electron donors to support microbial communities.
