Why do algal blooms occur, and what are the risks?
Algal blooms result from the combined effects of nutrient enrichment, water temperature, sunlight and water movement. Accumulated nitrogen and phosphorus, together with warm temperatures, intense sunlight and limited water exchange, can accelerate the growth of cyanobacteria.
Heavy and extra-heavy crude production fluids often form persistent emulsions that are difficult to dehydrate. To address this challenge, the R&D team at GN New Chem Technology Co., Ltd. has refined both the formulation and molecular structure of a demulsifier for heavy crude oil, with a focus on improving demulsification and oil–water separation under demanding conditions, including high asphaltene content and high salinity.
In slurry shield tunnelling, the circulating slurry balances earth and groundwater pressure, prevents face instability and water ingress, cools and lubricates the cutterhead and cutting tools, and carries excavated spoil to the surface through the slurry discharge lines.
Wastewater generated by industrial operations and municipal services is far more complex than simply “dirty water.” Suspended particles typically carry negative surface charges and are surrounded by an electrical double layer, causing them to repel one another and remain as stable colloids. Dissolved organics, oil, salts and other constituents further increase viscosity and turbidity. Together, these conditions slow floc formation and settling, hinder solid-liquid separation, and make COD removal difficult.
Large quantities of oil sludgeare generated during crude oil production, storage and transportation, refining, and other industrial operations.
Oil sludge is not simply a mixture of “oil + solids.” It is a complex multiphase system composed of crude oil, water, solid particles, and various organic constituents. During prolonged production and handling, chemical additives, mechanical shear, and other factors promote the formation of stable associations among the oil, water, and solids. Consequently, oil sludgeis one of the more challenging solid wastes encountered in industrial environmental management.
