### Oil separator

Oil separators are used to separate out oil from waste water and storm water into the local network.

### Density factor

Density factor allows differing densities for light liquids.

Densitet (g/cm3)
<= 0,85 0,85 - 0,90 0,9 - 0,95
Combination Density factor
S-II-P 1 2 3
S-I-P 1 1,5 2
S-II-I-P 1 1 1
Combiantion
Components Designation
Sludge seperator S
Seperator class I I
Seperator class IIII
Testing well P

A class I separators cleaner to a higher degree than a class II separators. Below are some examples of combinations.

Application Combination
Storm water from petrol stations, car parks, road, etc. S-II-P
Cleaning with cleaning agents (spills and leaks) in workshops. S-I-P
Cleaning without cleaning agents (spills and leaks) in workshops. S-II-P
Manually vehicle wash S-P
Automatic vehicle washing S-II-P

### Obstacle factor

Obstacle factor
0 Oil-contaminated stormwater from paved surfaces.
1 For the leakage of light mineral oils and protect the surrounding area.
2 Wastewater from industrial processes, vehicle washing, cleaning of oil-covered split etc.

### Nominal size

Nominal size the calculated value is used to select the appropriate size of an oil separator.

### Maximum sewagewater flow

Is the largest sewagewater flow from the actual plant that reaches oil separator.

### Maximum stormwater flow

Is the largest stormwater flow from the actual plant that reaches oil separator.

### Sludge seperator volume

It refers to the size of the chamber in the oil separator that handles the sludge that comes with the wastewater.

### Sludge quantity

Quantity Example
None Condensate
Small Processed wastewater sludge demonstrated little content.
Runoff surfaces of precipitation where small amount of sludge from traffic etc. are encountered.
Medium Minimum volume for sludge separation 600 l.
Gas stations
Manunal vehicle washing or bus washing.
Wastewater from garages and parkinglots.
High Minimum volume for sludge separation 600 l.
Washing facilities for construction equipment, agricultural machinery and the like.
Wash locations for trucks.
Automatic car wash The same calculation as for high sludge quantity but with a minimum volume of 5000 l.
