Breaking the Traditional Dilemma and Reshaping Separation Standards: An Analysis of SINOKLE's High-Efficiency Coalescing Oil-Water Separator
In high-energy-consuming industries such as petroleum refining and coal chemical engineering, oily wastewater treatment has always been a key process concerning environmental compliance and economic benefits. Facing increasingly stringent discharge standards and the practical challenge of limited space in old plant areas, traditional oil-water separation technologies have become inadequate.
SINOKLE Technology, deeply engaged in the field of fluid separation, has launched the high-efficiency coalescing oil-water separator (KHC), which breaks through the technical bottleneck with a pure-physical method, providing enterprises with efficient, green, and intensive water treatment solutions.
I. Direct Hit on Pain Points: Why Traditional Processes Can Hardly Continue?
For a long time, when treating oily wastewater, traditional gravity settling tanks, horizontal oil separation pools, and conventional flotation equipment have generally suffered from four major stubborn diseases:
Low separation precision:They can only remove free oil with particle size >50 microns, and are helpless against emulsified oil and tiny oil droplets (<10 microns), resulting in large fluctuations in effluent quality and difficulty in stably meeting standards.
Large footprint:Relying on long residence times (usually several hours), the equipment is bulky and civil construction costs are high, which is extremely unfavorable for the technical transformation and capacity expansion of existing factories.
High O&M costs:The internal structure is prone to clogging, requiring frequent shutdowns for cleaning or replacement of fillers; and most processes require large amounts of chemicals, generating secondary pollution (chemical sludge).
Poor shock resistance:When facing drastic fluctuations in water quality and quantity such as electric desalting drained water in refineries, the treatment effect is extremely unstable.
II. Technical Breakthrough: How Does KHC Work?
SINOKLE's high-efficiency coalescing oil-water separator is not an improvement of a single device, but a systematic engineering innovation integrating coalescence technology, shallow pool principle, and CFD flow field simulation. Its core working mechanism is divided into three steps:
Scientific flow distribution, pre-separation:The oily wastewater enters the equipment through a specially designed dual tangential inlet, using swirl centrifugal force to achieve initial energy dissipation and uniform flow distribution. This step quickly strips large oil droplets and heavy sand particles, reducing the burden for subsequent fine separation.
Core coalescence, micron-level capture:This is where the soul of the technology lies. The water flow passes through the separation zone filled with SINOKLE's patented modified coalescing filler. This super-oleophilic and hydrophobic material adsorbs tiny oil droplets like a magnet, causing them to wet, spread, and coalesce on the fiber surface, rapidly growing from micron scale to millimeter-scale large oil droplets, with demulsification precision up to 0.1 micron.
Shallow Pool Separation, Rapid Upward Flotation:Based on the shallow pool principle, the equipment greatly shortens the upward flotation path of oil droplets. The coalesced large oil droplets instantly float up to the top oil collection package and are recovered through the automatic oil discharge system; at the same time, the special sand flushing system at the bottom ensures dead-corner-free sludge discharge, thoroughly solving the clogging problem.
The entire process requires no chemical agent intervention, truly achieving pure-physical, high-efficiency oil-water separation.
III. Data as Witness: Hard-core Strength from Lab to Industrial Site
The advancement of theory needs to be tested by practice. SINOKLE KHC has been operating stably in multiple national key petrochemical projects, delivering impressive report cards:
A thermal power cogeneration project in Shaanxioily wastewater treatment project
A back-pressure thermal power cogeneration construction project in Shaanxi, where the oily wastewater generated by the power plant had an oil content as high as 500,000 ppm (about 50%), making it extremely difficult to treat. SINOKLE adopted a combined process of pre-filter plus KHC coalescing oil-water separator, ultimately reducing the effluent oil content to below 5 ppm, with a removal rate exceeding 99%, far exceeding discharge standards.
A coking acidic wastewater project of a refinery in Henanhighly emulsified oily wastewater treatment
Built and put into operation in 2020, with a treatment scale of 15 cubic meters per hour. The project adopted a pure-physical treatment process, with the core equipment being theCDFUswirl dissolved air flotation unit and KHC coalescing oil-water separator. The project achieved remarkable treatment results, reducing the influent oil content from as high as 15,000 mg/L to below 98 mg/L in the effluent, and suspended solids from 500 mg/L to 8.2 mg/L. The entire process is short, the equipment structure is compact, the footprint is only 12 m x 3 m, and it adopts skid-mounted, automated design, with easy O&M and short construction period.
IV.Value Sublimation: Not Just Environmental Protection, But Also Benefits
SINOKLEhigh-efficiency coalescing oil-water separator, its significance goes far beyond treating wastewater; it brings a triple-value leap to enterprises:
New Heights of Green Production:Abandoning chemical demulsifiers eliminates chemical sludge hazardous waste from the source, helping enterprises achieve low-carbon, clean production.
Maximizing Economic Benefits:The recovered waste oil has extremely low water content (as low as 0.1%), can be directly recycled as raw material, turning waste into treasure and directly creating economic benefits.
Optimal Solution for Technical Transformation and Upgrading:Modular skid-mounted design with minimal footprint perfectly adapts to the renovation needs of old plant areas with limited space, achieving a dual improvement in capacity and standards without large-scale civil construction.
