Separator systems for light liquids (e.g. oil and petrol) - Part 1: Principles of product design, performance and testing, marking and quality control

This standard deals with installations for the separation of light liquids (e.g. oil and petrol), i.e. those with a density up to 0.95 g/cm3 from waste water by means of gravity and/or coalescence. The standard is not primarily intended to apply to installations that are required to treat large quantities of trade effluent (e.g., oil refinery effluent). The standard may, however, still be appropriate for this purpose depending on local requirements.

Analysis of effluent samples
A.1 General

Samples shall be analysed for their hydrocarbon content using infrared spectroscopy in accordance with A.2 or gas

chromatography in accordance with A.3.
In case of dispute, the infrared spectroscopy method is the reference method.
A.2 Infrared spectroscopy method
A.2.1 Extraction and preparation of the extract

An effluent sample of approximately 500 ml is weighed into a separating funnel with a rated volume of 1000 ml,

directly from the sampling device (see Figure A.1). Within 15 min of sampling the pH shall be set to between 1 and

2 using sulphuric acid (H SO ) and 50 ml of 1.1.2-trichloro-1.2.2-trifluoroethane (C Cl F ) shall be added. It is then

2 4 2 3 3

immediately shaken, with a frequency of 3 Hz to 4 Hz for 10 min and the phases allowed to settle for 30 min.

Alternatively, tetrachloroethylene (C Cl ) (IR grade) may be used as the extraction solvent.

If the samples have to be transported to an external laboratory, they shall be weighed into glass bottles. The

samples shall be preserved within 15 min by addition of acid as described above. They shall either be further

---------------------- Page: 8 ----------------------
EN 858-1:2002/A1:2004 (E)

preserved by addition of 1.1.2-trichloro-1.2.2-trifluoroethane as above before transport, or they shall be sent to the

analysis laboratory at 4°C. If preserved by solvent, at the analysis laboratory the samples shall be transferred to

separating funnels for extraction as above. If the samples have been refrigerated then the solvent should be added

to the sample bottle, then transferred to separating funnels for extraction as above.

After phase separation the organic fraction is run off and immediately filtered through approximately 10 g of

anhydrous sodium sulphate (Na SO ) into a volumetric flask with a rated volume of 50 ml. The extract is made up

to the mark with the solvent, washed through the sodium sulphate so as to include any hydrocarbons remaining in

the sodium sulphate.
A.2.2 Evaluation

Measurement is made against a reference of the pure solvent of same layer thickness using matched cuvettes of

equal length. Before measurement, a transmission value of exactly 100 % shall be set with the cuvettes inserted, at

3,2 µm. Those absorption bands showing 3,38 µm and 3,42 µm shall be recorded.
The mass concentration of the hydrocarbons in the water sample is obtained from:
1, 4⋅V (E / C +E / C )
TE 1 1 2 2
G = (A.1)
V ⋅d
where
G is the mass concentration of the hydrocarbons in the water sample, in mg/l;
V is the volume of the extracting agent used for extraction, in ml;
E is the spectral absorption magnitude of CH band at 3,38 µm;
1 3
C is the molecular extinction coefficient of the CH band (8,3 ml/mg · cm);
1 3
E is the spectral absorption magnitude of CH band at 3,42 µm;
2 2
C is the molecular extinction coefficient of the CH band (5,4 ml/mg · cm);
2 2
V is the volume of water sample used, in l;
d is the layer thickness of absorbent solution, in cm.
The result is indicated as a rounded value to an accuracy of:
0,1 mg/l for < 10 mg/l and
1 mg/l for ≥ 10 mg/l.

Fuel oil ISO-F-DMA in accordance with 8.3.3.1.2 shall be used as the reference liquid for calibration, i.e. to

determine the group absorbance coefficients.

It is possible to use "fixed wavelength" infrared devices when the hydrocarbon concentrations are more than

5,0 mg/l. With this method the hydrocarbon concentration is evaluated solely using the CH absorption band at

3,42 µm. The fuel oil in accordance with 8.3.3.1.2 shall be used for calibration. Extraction and preparation of the

extract shall be as described in A.2.1.

A.3.1 General

This instruction describes a simplified analytical method based on EN ISO 9377-2 to determine fuel oil ISO-F-DMA

in accordance with 8.3.3.1.2 in water by gas chromatography (GC). The method is suitable for determining fuel oil,

if the concentration is greater than 1 mg/l. This method is not suitable for wastewater.

The samples are extracted in petroleum ether, then analysed by gas chromatography between C and C .
