Fat Separator

FAT and starch separators

Separators of fat substances and starch with a valve – key

Separators of fat substances and starch without a valve – key

Technical specifications of separators on the example of machines without suction valve

Neutralization chambers

Additional equipment: settling tanks, superstructures

 

Application of the separator of fat substances and starch: the basic purpose of the fat separator is to retain all solid particulates, vegetable and animal fats.

The machine is designed for treatment of the technological wastewaters from, among others, hotels, fast-foods, restaurants, catering places, slaughterhouses, abattoirs, food processing plants, etc.

 

The DIN 4040 standard and the PN EN 1825 standard, according to which our fat separators are designed, distinguish four main criteria enabling a proper selection of the machine:

Maximum daily flow of the wastewater

Wastewater temperature

Fat content in the wastewater

Detergent content in the wastewater 

The proper amount of the separator flow is determined by the following formula: 

Q = P x Wt  x Wg x Wd

where: 

P    - means the maximum daily flow 

Wt – means the temperature coefficient

Wg – means the coefficient of fat density in the wastewater

Wd – means the detergent coefficient 

Wt = 1    - for wastewaters with a temperature below 60 ºC

Wt = 1,3 – for wastewaters with a temperature above 60 ºC 

For wastewaters from restaurants, slaughterhouses, butcher’s shops and other facilities of this type, it is assumed that the degree of fat concentration in the wastewater is below 0,94 g/cm3. In this case: Wg = 1

For some types of fats like the oily ones whose density is above 0,94 g/cm3, Wg = 1,3 should be assumed.

 

When using auxiliary detergents and other cleaning agents hindering the separation, Wd = 1,3

 

How to calculate a given “P”: Machine selection according to type and size of the installation

The maximum daily flow “P” may be calculated by formula:

   Q1 x T

P =  ---------------

     t x 3600

where:

Q1 – average daily amount of the wastewater

  - coefficient of the hourly inequality

t     - average installation operating time

 

The "T" coefficient for various production and gastronomic facilities shall be as follows: 

T - hotel - 5

T - restaurant - 8

T - canteen - 20

T - hospital - 13

T - small meat processing plant, up to 5 LU per week - 30

T - medium meat processing plant, up to 10 LU per week - 35

T - large meat processing plant, up to 40 LU per week - 40 

1 LU = processing of 1 ox / 2.5 pigs 

Q1 – should be assumed on the basis of the actual measurements of water consumption, when this is impossible according to the guidelines provided by the Manufacturer. 

And so, for mass catering facilities shall be assumed: 

Q1 = G x Zw

where: 

G   - number of hot meals prepared within one day

Zw – water consumption in liters to prepare one meal 

Zw - hotel - 80 L

Zw - restaurant - 50 L

Zw - canteen - 10 L

Zw - hospital - 20 L 

And for meat processing plants shall be assumed: 

Q1 = G1 x Zw1

where:

G1 – daily production of sausage products in kilos

Zw1 – water consumption in liters per 1 kilo of a product 

"Zw1" for different sizes of plants shall be assumed according to the following statement: 

Zw1 - small meat processing plant, up to 5 LU per week - 20

Zw1 - medium meat processing plant, up to 10 LU per week - 15

Zw1 - large meat processing plant, up to 40 LU per week - 10
