Our team is delighted to offer integrated and one-stop solutions for oil and gas field sewage treatment and soil remediation.

Our five sewage treatment technologies covering every production stage in oil and gas fields, all of which have been successfully implemented in engineering projects. For other types of sewage, we can flexibly combine various technologies to address a wide range of treatment needs.

Additionally, our three key technologies for petroleum hydrocarbon-contaminated soil remediation enable us to provide systematic and tailored remediation service solutions, designed to meet different pollution levels and soil usage requirements.
