Kitchen waste oil and water separation equipment
(Also known as catering oil-water separator, oil separator) is an environmental protection equipment specially used to treat oily wastewater from catering, canteens, food processing plants, etc. The core is to
Oil, water, slag
Three-phase efficient separation prevents pipeline blockage, meets environmental protection emissions, and recycles waste oil resources.

First, the core working principle (physical separation, no secondary pollution)
Mainly use
density difference
(Oil
0.91–0.93g/cm³
水 1g/cm³),配合多级工艺强化:
1.
Pretreatment (slag removal)
:
304不锈钢滤网 / 格栅,自动拦截饭粒、菜叶、骨头等固体残渣,底部螺旋 / 刮板自动排渣。
2.
Gravity settlement (main separation)
Wastewater slows down and stops, and large oil droplets naturally float up to the oil collection area; water is in the lower layer, ready to be discharged.
3.
coalesce
/
斜板强化Corrugated plates and inclined pipes are installed inside to allow tiny oil droplets to collide and polymerize into large oil droplets, improving efficiency
40%+
。
4.
Air flotation (high matching)
: microbubbles (
≤50μm
Adhering to oil droplets, it floats quickly, suitable for high oil, emulsified oil, and low temperature scenarios.
5.
filter
/
深度净化: Fine filtration before effluent to ensure compliance (oil content in effluent)
≤15mg/L
)。
II. Main types and applicable scenarios
1.无动力(重力)型

principle
: Strong oil removal with dissolved air micro-bubbles
•
efficiency
:
95–98%
,可处理乳化油
•
apply
Hot pot restaurants, deep-frying shops, places with extremely high oil content
4.离心式(工业大型)
•
principle
High-speed centrifugal force rapid separation
•
advantage
Small footprint and extremely fast speed
•
apply
Central kitchen, food processing plant, processing capacity
≥10t/h
III. Core functions and values
•
anti-blocking baotong
Avoid grease solidification to block sewers and reduce dredging costs
•
Environmental compliance
: Meet the "Integrated Sewage Discharge Standard"
GB8978
,避免罚款
•
Waste oil recovery
The waste oil collected can be processed into biodiesel and industrial oil, turning waste into treasure
•
Reduce operations
Automatic slag discharge and oil discharge, greatly reducing the cost of manual cleaning
IV. Selection points (commonly used in catering)
•
throughput
By seat
/
日用水量估算(如 100 座≈5–10m³/d)
•
Installation method
Buried type, wall-mounted type, ground type, basement lifting type
•
material
:
304不锈钢(Corrosion resistant, easy to clean, long lifespan)
•
function
: Do you want
Automatic slag discharge, automatic oil scraping, heating, lifting pump
(Basement required)
Installation and maintenance
•
install
: The water inlet end is connected to the dishwasher.
/
后厨排水,出水接市政管网;预留检修空间
•
maintain
:
○
Daily: Check whether the slag and oil discharge are normal
○
Weekly: clean the filter, rinse the box
○
Monthly: check motor, heating, control system
