Project: Hazardous Waste Treatment System for Daqing Oilfield

This is a custom hazardous waste treatment system for Daqing Oilfield, designed to treat oily sludge, waste oil sands and other hazardous wastes generated during oil extraction and transportation. The system adopts pyrolysis + oil and gas recovery technology to achieve harmless, reduced-volume and resourceful treatment.

It integrates pretreatment, pyrolysis, condensation recovery and tail gas purification units, efficiently recovering oil from oily sludge while ensuring stable discharge of treated residues and energy recycling. With stable operation and high automation, the system meets the oilfield’s high-load, continuous operation requirements, effectively solving the problem of hazardous waste disposal and reducing the client’s environmental compliance risks. It has become a benchmark application in the domestic oilfield hazardous waste treatment sector.

Project: Rural Sewage Treatment Project by China Energy Engineering Group

This project is a rural environmental improvement initiative undertaken by China Energy Engineering Group, designed for decentralized domestic sewage in northern China villages. It uses buried integrated wastewater treatment units with capacities ranging from 5–50 m³/d per village, adopting A/O biological treatment technology.

The fully buried installation occupies no farmland and requires no above-ground building, allowing the land above to be restored for planting. Built to withstand low temperatures and variable loads, the system ensures effluent quality meets the Class 1 standard for rural sewage discharge, suitable for discharge or farm irrigation. Since commissioning, it has effectively solved problems such as random sewage discharge and black-odor water bodies, improving the rural environment and supporting the construction of beautiful villages.

Project: Integrated Wastewater Treatment for an Industrial Park

This is a custom wastewater treatment solution for an industrial park in China, with a daily capacity of 500 m³/d. The system adopts A/O biological treatment combined with lamella clarification and advanced filtration, ensuring effluent quality stably meets the Class 1A standard of China’s municipal wastewater discharge regulations.

Designed with a combination of on-site concrete tanks and skid-mounted equipment, the system features a compact footprint and high automation for 24/7 unattended operation. Since commissioning, it has effectively handled mixed industrial and domestic sewage from the park, reducing operational costs and supporting the client’s compliance with environmental regulations and sustainable production goals.

Project: 35 m³/d RO Seawater Desalination Plant in Coastal Africa

This is a custom reverse osmosis (RO) seawater desalination solution for a remote coastal community in Africa, with a daily capacity of 35 m³/d. Designed to meet local domestic and small industrial water demands, the system uses pre-treatment + single-pass RO technology to remove salt, impurities and microorganisms, converting seawater into safe, stable drinking and domestic water.

Built as a compact, skid-mounted unit with high automation, the system operates reliably in harsh high-temperature, high-humidity conditions and requires minimal maintenance. Since commissioning, it has effectively solved the local freshwater shortage, providing a stable water supply for residents and small industries — making it one of our successful reference projects in the African market.
