Oil-water separation equipment
It is an environmentally friendly equipment that uses physical (gravity, air flotation, centrifugation, filtration) or chemical principles to separate oil, water, and solid impurities in oily liquids. The core is
oil removal, standard discharge, anti-blocking, grease recovery
。
First, the core working principle (physics-based)
1.
Gravity separation (the most basic)
Utilize oil (
0.8–0.95
）、水（1.0）密度差，油自然上浮、水下沉；加斜板 / 波纹板延长路径、加速聚结。
•
Applicable: Large particle oil slick (
> 150μm
）、餐饮初级处理。
2.
Coagulation (coarse graining) separation
Small oil droplets collide with corrugated plates and fiber materials to form large oil droplets, which are easy to float.
•
Applicable: dispersed oil (
20-150μm
）、餐饮 / 工业精细分离。
3.
air flotation separation
Micro bubbles adhere to oil droplets and float to treat emulsified oil and oil with a density near water.
•
Applicable: industrial emulsion, petrochemical wastewater.
4.
centrifugal separation
High-speed rotation generates strong centrifugal force, rapid stratification, and a small footprint.
•
Applicable: ship, vehicle, small size and high demand scenarios.
5.
filter
/
吸附Hydrophilic and oleophobic materials allow water to pass through and cut oil; deep oil removal is possible.
•
Applicable: deep purification of water outlet (
≤10mg/L
）。
II. Main types and applications
1）餐饮油水分离器（厨房 / 食堂 / 火锅店）
•
Unpowered: Gravity
+
斜板，结构简单、低成本，适合小餐馆。
•
Fully automatic (
GBOS
系列）：智能传感、自动刮油、加热防凝固（牛油）、一体化除渣，效率≥95%，出水≤10–15mg/L。
2）工业油水分离器
•
Machining: Purifying cutting fluid
/
乳化液、除油除菌、循环复用。
•
oil
/
化工 / 汽修：气浮 + 聚结 + 过滤，处理矿物油、乳化油。
•
Ship: compliant
IMO 15ppm
标准，舱底水处理。
3）其他
•
Compressed air oil-water separator: remove water, oil and impurities from gas.
•
underground
/
商场隔油提升：一体化分离 + 提升，解决地下排水。
III. Comparison with traditional grease traps
•
grease trap
Gravity only, no power, efficiency
60–70%
、占地大、人工清渣。
•
Oil-water separator
Composite technology, efficiency
95%+
、自动排油、可处理乳化油、达标排放。
IV. Selection points
