Wastewater produced during mud tank cleaning typically contains drilling fluid residues, fine suspended solids, clay particles, oil, polymers and other chemical additives. Its composition can vary significantly depending on the drilling fluid system, tank-cleaning method and operating conditions. These characteristics make effective treatment more challenging than conventional wastewater clarification.

To address these challenges, GN developed a complete treatment solution incorporating solids separation, chemical conditioning and process control. The four systems will help the customer separate suspended solids and contaminants from the wastewater while reducing the volume of residual sludge requiring further handling.

Supporting Customers Around the World

Over the years, GN has supplied separation and environmental protection equipment to customers in many countries and regions. Its systems are widely used in oil and gas drilling, solids control, drilling waste management, oily sludge treatment, industrial wastewater treatment and mineral processing. GN places strong emphasis on building long-term relationships rather than focusing only on individual equipment deliveries. Through continuous communication, application analysis, technical support and after-sales service, the company works closely with customers to respond to changing operating conditions and treatment requirements. The delivery of these four systems to Africa represents another practical example of GN’s growing international presence and its ability to provide solutions adapted to local projects.

Combining Equipment with Specialized Chemicals

Wastewater treatment performance depends not only on the mechanical equipment but also on the correct selection and application of treatment chemicals. Different wastewater streams may require different coagulation, flocculation, demulsification, pH adjustment or sludge-conditioning programs. As a wholly owned subsidiary of Hebei GN Solids Control Co., Ltd., GN New Chem Technology Co., Ltd. works alongside its parent company to provide application-specific chemical products and technical services. This cooperation combines GN’s equipment engineering and manufacturing capabilities with GN New Chem’s formulation development, laboratory testing and chemical application expertise. Before recommending a chemical program, the technical team can evaluate representative wastewater samples, identify key treatment challenges and conduct laboratory screening. The results can then be used to select suitable chemicals, determine preliminary dosage ranges and optimize the overall treatment process. By coordinating chemicals, equipment and operating parameters, GN can help customers achieve more stable treatment performance, reduce unnecessary chemical consumption and improve the efficiency of solid-liquid separation.

Integrated Solutions for Complex Industrial Applications

GN New Chem focuses on four principal business areas:

• Oil sludge separation and treatment chemicals
• Industrial wastewater treatment chemicals
• Drilling fluid additives
• Oil and gas production chemicals

Its product portfolio includes coagulants, flocculants, demulsifiers, oil-sludge washing agents, wetting and dispersing agents, drilling fluid viscosifiers, fluid-loss control additives, shale inhibitors, lubricants, corrosion inhibitors, scale inhibitors, paraffin-control chemicals and asphaltene-control products.

Supported by professional laboratories, pilot-testing capabilities, manufacturing resources and technical service teams, GN New Chem develops customized chemical programs for different feed materials, water qualities, process configurations and treatment objectives.

Delivering Greater Value Through an Integrated Approach

The successful delivery of these four drilling mud tank cleaning wastewater treatment systems demonstrates GN’s commitment to providing more than standalone machinery. By integrating process design, separation equipment, specialized chemicals and technical support, GN offers customers a coordinated solution covering the complete treatment process.

Going forward, GN and GN New Chem will continue to strengthen their combined “chemicals + equipment + solutions” capabilities. Through reliable products, application-based formulation development and responsive technical services, the companies aim to help customers around the world improve treatment efficiency, control operating costs and achieve safer, more sustainable operations.
