Catering oil and water separator
It is installed in the back kitchen of the catering and is used to transfer oily wastewater
Grease, food waste
Special environmental protection equipment for water separation, the core function is to
Prevent pipeline blockage, meet environmental emission requirements, and recycle waste oil
。
First, the core working principle
based on
physical separation
(No chemical additives), the main three steps:
1.
slag removal
Filter first
/
格栅拦截菜叶、饭粒、骨头等固体残渣。
2.
oil-water separation
: use
Oil (
0.89–0.93g/cm³
）比水轻The density is poor, the oil floats and the water sinks.
3.
deep purification
: High-end models plus
Coalescing plate
/
加热 / 气浮Let the small oil droplets gather larger, break the emulsion, and be more efficient.
Two, three major types (by automation)
/
效率）
1.无动力（重力）型
•
principle
Pure density difference naturally rises, no motor.
•
apply
: Small restaurants, noodle shops, snack bars (daily displacement <
10m³
）。
•
advantage
：
Zero electricity bills, cheap (
2千–6 千）、免维护、安装简单。
•
disadvantage
: Efficiency is approximately
80–90%
It is easy to block at low temperature and requires manual cleaning of slag and oil.
2.半自动 / 自动型（带刮油 / 加热）
•
principle
: Gravity
+
Automatic oil scraper
+
恒温加热(Anti-lard
/
牛油凝固）。
•
apply
Medium-sized restaurants, restaurants, chain restaurants (
10–30m³/
天）。
•
advantage
: efficiency
95%+
Automatic oil discharge, stable in winter, and less labor.
•
price
：
1–3
万元。
3.全自动（一体化 / 气浮）
•
principle
: Automatic slag removal
+
气浮 / 深度聚结 + 智能控制。
•
apply
：
Hot pot restaurant, fried restaurant, food city, large canteen
(High oil
/
大水量）。
•
advantage
：
The whole process is automated and efficient
98%+
、达标稳、可远程监控。
•
price
：
3–10
万元 +。
III. Core functions and benefits
•
anti-blocking
Avoid grease solidification to block sewers and reduce dredging costs.
•
Environmental compliance
: Oil content of effluent
≤15mg/L
, satisfied
GB/T 31962
，过环评。
•
Waste oil recovery
The separated waste oil can be sold to qualified units to make biodiesel.
•
hygiene
Reduce odor and cockroach growth.
IV. Selection points (how to choose)
1.
Look at the scale
￮
Shop:
unpowered
￮
Chinese food
/
酒楼：Automatic heating type
￮
Hot pot
/
油炸 / 综合体：Automatic air flotation
/
一体化
2.
see the amount of water
￮
press
displacement per hour
1.5double
Select the model (peak margin)
3.
Look at the material
￮
preferred
304不锈钢(Corrosion resistant, easy to clean, long lifespan)
4.
Look at the function
￮
North
/
高油：必选heating
￮
Many residues: choose
Automatic slag removal
Installation and maintenance
•
install
: Near the kitchen drain (
≤15m
), ground level, reserved maintenance space.
•
maintain
：
￮
Unpowered:
Weekly slag cleaning, monthly oil cleaning
￮
Automatic type: regularly check whether the heating, oil scraping and oil discharge are normal
VI. Regulatory requirements
•
Most cities across the country
mandatory requirement
Catering installation of oil-water separator, otherwise
Fines, suspension of business, failure to apply for a license
。
Must ensure
The effluent meets the standard
, and by a qualified unit
Recycle used oil
(It is strictly forbidden to return gutter oil).
