Refining & Chemicals

Refining & Chemical industries provide the world’s critical raw materials. They require significant quantities of water throughout their operations for steam production, cooling, process make-up, utility water, and product rinsing. Complex industrial wastewaters are generated, requiring innovative and cost-optimized solutions before discharge to ensure safe and reliable environmental compliance.

Wastewater consists of high concentrations of oil & grease, COD, and organic and inorganic contaminants that would harm the environment. Some, such as surfactants and petroleum hydrocarbons, reduce performance efficiency and must be removed as part of pretreatment.

Gradiant has robust, proven, and cost-effective technologies to deliver a range of solutions to refineries, including:

Preliminary treatment to remove large solids
Primary treatment to remove organic and inorganic solids
Secondary treatment to oxidize and biologically digest organics
Tertiary treatment to polish the effluent for reuse or discharge
Resource recovery for valuable metals or minerals
MLD or ZLD treatment to minimize or eliminate water discharge/disposal
Custom engineering to meet specific mechanical, electrical, automation, O&M, and safety requirements
