The majority of industrial branches, as a result of production activities and \/ or exploitation, produce large quantities of oils and insoluble liquids are generated. Due to the density difference to water, they form a microfilm on the surface of waters, diminishing the transfer of oxygen between the external environment and the hydrostatic parameters of water, with very harmful effects on the aquatic ecosystems.<\/p>\n
For these reasons, it is necessary to pre-treat the water before it is discharged into the environment.<\/p>\n
<\/p>\n
Areas of use for hydrocarbon separators<\/b>: any concrete platform with an area of \u200b\u200bmore than 50 square meters, gas stations, car parks, services, etc. Having an efficient functionality, due to the coalescent filter with automatic shutter, the hydrocarbon separator also covers the separation of the water from the coarse side of the platforms: sand, mud, etc., having a decanter\/sand trap incorporated.<\/p>\n
<\/p>\n
Depending on the quality of the treated water, there are two classes of hydrocarbon separator:<\/p>\n
<\/p>\n
\n- 1st Class hydrocarbon separator: Processed water contains hydrocarbons below 5 mg \/ l, according to the water analysis of NF EN 858-1 and NTPA-001 (Coalescent filter model).<\/li>\n<\/ul>\n
<\/p>\n
\n- 2nd Class hydrocarbon separator: Processed water contains hydrocarbons below 100 mg \/ l, in accordance with the water analysis of NF EN 858-1 and NTPA-002 (Model without coalescent filter).<\/li>\n<\/ul>\n
<\/p>\n
By-pass hydrocarbon separators<\/b><\/p>\n
<\/p>\n
By-pass hydrocarbon separator allows higher flow rates to be treated in the event of a storm, up to five times the nominal flow rate.<\/p>\n
<\/p>\n
The amount of water entering the separator decanter is limited. However, when the flow is above the permissible limit, the higher level is evacuated through the bypass, without disturbing the operation of the separator.<\/p>\n<\/div>
