From Gravity Settling to Supergravity Cyclone: How SINOKLE Redefines the Efficiency of Industrial Oily Wastewater Treatment
In the fields of petroleum refining, chemicals, municipal services and industrial production, oily wastewater treatment has always been a core environmental challenge. As domestic discharge standards become increasingly stringent, enterprises are placing higher demands on the efficiency, stability and compactness of wastewater treatment equipment. Due to technical limitations, conventional equipment generally suffers from shortcomings such as low treatment efficiency, a large footprint, complex O&M and poor adaptability, making it difficult to meet current wastewater treatment needs characterized by high concentration, fine particle size and large fluctuations. The market urgently needs new solutions that are technologically advanced, reliably performing and energy-saving and low-carbon.
SINOKLE has long been deeply engaged in the field of oil-water separation and has independently developed a series of core products including high-efficiency hydraulic cyclones,CDFUcyclonic dissolved gas flotation units, high-efficiency coalescing pressure oil removers (KHC) and ozone advanced catalytic oxidation units (CDOF). With supergravity cyclonic separation at its core and integrating multiple patented technologies such as CFD flow field optimization, micro-bubble flotation and high-efficiency coalescence, the company has thoroughly broken through the limitations of conventional equipment. Its equipment maintains oil removal efficiency stable at 90%-95% or above, and the effluent oil content can be reduced to below 5 mg/L, making it the preferred solution for efficient and stable treatment of industrial oily wastewater, with broad market application prospects.
1. Core Bottlenecks of Conventional Oily Wastewater Treatment Technology
Conventional processes such as gravity settling tanks, ordinary flotation machines and conventional filters have revealed many insurmountable defects in long-term application:
1. Low efficiency, insufficient precision:conventional gravity settling can only remove large floating oil particles and is almost ineffective against emulsified oil andfine oil droplets below 10 microns, resulting in unstable effluent quality that struggles to meet standards.
2. Huge footprint, high investment:settling tanks and open flotation equipment are enormous in volume and require large-scale civil works, involving not only a large footprint but also extremely high infrastructure costs, which is especially unfavorable for technical retrofits of old plants.
3. Unstable operation, cumbersome O&M:the internal flow regime of the equipment is prone to turbulence and has poor resistance to shocks in water quality and volume, causing large fluctuations in treatment performance. At the same time, packing is prone to clogging and components to damage, requiring frequent shutdowns for cleaning and replacement, keeping labor and consumable costs high.
4. Poor flexibility, weak adaptability:most are fixed process modes, making it difficult to adjust flexibly according to different influent water quality (such as high oil content or high suspended solids), and treatment performance is greatly compromised when facing complex conditions in refining and oilfields.
2. Technical Advantages and Performance Breakthroughs of SINOKLE's Core Equipment
In response to industry pain points, SINOKLE provides a full range of technical solutions, with its core equipment offering significant advantages:
In response to industry pain points, SINOKLE has independently developed a new generation of high-efficiency oil-water separation equipment. Led by the high-efficiency hydraulic cyclone, this series integrates multiple core technologies such as supergravity cyclone,CFD fluid optimization and zoned precision treatment, comprehensively making up for the shortcomings of conventional equipment, with core performance reaching international advanced levels and outstanding results across key indicators.
SINOKLE's high-efficiency hydraulic cyclone is based on supergravity cyclonic separation technology; through a special internal structure it generates a high-intensity cyclone, forming a powerful centrifugal force field hundreds to thousands of times the acceleration of gravity. Under the centripetal force, fine oil droplets in the water rapidly collide, coalesce and grow, achieving efficient and rapid oil-water separation and thoroughly breaking through the efficiency bottleneck of conventional equipment. The equipment achieves an oil removal efficiency as high as90%-95% and can precisely remove fine oil droplets smaller than 10 microns, effectively solving the industry problem of conventional equipment struggling to treat emulsified oil and fine oil droplets, and ensuring that the effluent oil content remains consistently compliant.
Relying onCFD fluid optimization design, the internal flow regime of the equipment is smooth and uniform, with no turbulence or shock during operation; performance remains stable over time and is not easily affected by fluctuations in water quality or volume, enabling long-term continuous and reliable operation with an extremely low failure rate. At the same time, the compact structural design means the equipment is small in size and light in weight, with a footprint of only 1/3 or even less than that of conventional settling and flotation equipment, requiring no large-scale civil works; whether for new projects or old retrofits, it adapts easily and significantly reduces upfront investment.
The equipment adopts a zoned modular design, allowing operating parameters to be flexibly adjusted according to different oily wastewater quality and treatment volumes. It suits a wide range of complex scenarios such as refining wastewater, oilfield wastewater and industrial oily wastewater, with strong adaptability. The entire series achieves standardized, skid-mounted integration, with complete unit commissioning before delivery and simple on-site installation -- simply connect the pipelines and it is ready for operation. Later maintenance is simple and convenient, requiring no dedicated staffing and only routine inspections, greatly reducing O&M difficulty and labor costs, with a full-life-cycle cost-performance far exceeding conventional equipment.
3. Broad Application Scenarios and Proven Market Value
