Oil-water separator
It's an exploit.
Physical or chemical methods
In the oily liquid
Efficient separation of oil and water
The core function of environmental protection equipment is to
Wastewater discharge standards
with
Waste oil recycling
。
First, the core working principle
Mainly based on
Density difference between oil and water
(Oil about
0.8–0.93 g/cm³
，水 1 g/cm³），辅以多种技术强化分离：
1.
Gravity separation (basic)
The sewage flows slowly and stands, and the oil naturally rises and the water sinks. Interior
inclined plate
/
波纹板Extend the path and accelerate coalescence.
•
Advantages:
No power, low cost, easy maintenance
。
•
Limitations: Yes
Emulsified oil, tiny oil droplets
Bad results.
2.
Coalescence separation (reinforcement)
passed
Lipophilic fiber
/
滤材Let the micro oil droplets coalesce into large oil droplets, and then float up to separate.
•
Advantages: Separation efficiency
≥95%
, can be handled
10-100μm
Fine oil droplets.
3.
Air flotation separation (fine)
injection
microbubbles
（
50-100μm
）吸附油滴，快速上浮成浮渣刮除。
•
Advantages: Can handle
emulsified oil
The accuracy can be achieved
5ppm
以下。
4.
Centrifugal separation (high speed)
High speed rotation
Strong centrifugal force
The oil is thrown towards the center and the water is thrown towards the outer wall, instantly layering.
•
Advantages:
Extremely efficient (
99%+
）、占地小、速度快。
II. Main types and characteristics
1.按技术原理
•
Gravity type (grease trap)
Simple structure, low cost, suitable for

Medium and high concentration, containing emulsified oil
Waste water (e.g. food processing, commercial complexes).
•
centrifugal
Fast processing, small footprint, suitable for
High oil, low flow, emergency scenarios
。
•
Intelligent integration (e.g.
GBOS
系列）integration
gravity
+
聚结 + 气浮 + 加热 + 自动排渣Fully automated, IoT monitoring, efficiency
≥96%
。
2.按应用场景
•
catering only
slag removal
+

, often matched
Explosion-proof, air flotation, deep filtration
。
•
Marine only
meet
IMO
Standard, anti-tilt, anti-vibration, treatment
Engine room bilge water
（
≤15ppm
Emissions).
