Separation for oil-water is an important step in the early pretreatment of industrial wastewater, and no volatile organic compounds (VOCs) are produced after treatment

Semi-coke wastewater is generated during the carbonization in medium and low temperature (about 650°C) , primarily source from the circulating water used for cooling and washing coal gas, as well as the water during the process of chemical production. Semi-coke undergoes carbonization in low-temperature , resulting in a high yield of tar and abundant low-molecular organic substance during production. Consequently, the wastewater contains a significant amount of pollutants that have not been oxidized by high temperatures, with a concentration approximately 10 times higher than other coking wastewater, making it more challenging to treat than other coking wastewater.

Oily wastewater in the tank source from the dock, the tank area,and oil distribution facilities. The oily wastewater from the dock primarily comprises ballast water from oil tankers, tank cleaning water, and top water of process; the oily wastewater from oil distribution facilities mainly includes wastewater produced during the operation of loading platforms, pump rooms, and associated pipelines; and the oily wastewater from the tank area constitutes the majority of the oily wastewater in the oil depot, which includes cut water from tank , tank cleaning water, equipment and ground flushing water, and contaminated rainwater.

Most of oilfields in China have entered into the later stage of exploitation and utilization, especially the development of low-permeability oilfields, which require the injection of a large amount of water to maintain good permeability pressure. During the exploitation of oilfields, the water content of the crude oil extracted increases year by year, and the amount of produced water also rises accordingly. The main methods for treating the produced water are oil and suspended solids removal.

We specialize in undertaking outsourced operations for oily wastewater in industries such as petrochemical, coal chemical, and new energy. We upgrade and transform existing processes for oil removal , achieving zero chemical addition, no secondary pollution, and no hazardous waste generation in the processes of removing oil from wastewater . We also facilitate the resource utilization of oily wastes. Additionally, we can collaborate and achieve win-win results through various modes such as EPC, BOT, and BOO.

Circulating water for cooling is a type of water that uses water as the cooling medium. It is transported by conveying equipment to the water cooler of the process system, absorbs heat, and then is cooled by recycling facilities for cooling . The circulation of cooling water forms an independent system, known as the circulating system for cooling water . It consists of heat exchanger equipment such as air cooling towers, heat exchangers, and condensers, cooling equipment such as cooling towers, treatment facilities such as sedimentation tanks and filters, water pumps, pipelines, and other related facilities.
