|… example for chemical waste water|
|Sewage type:||Deicing fluid (different kinds of glycol)|
|Sewage properties:||- Strongly fluctuating
concentrations from COD 20 mg/l up to
300 000 mg/l, in average COD 11 000 mg/l
- Deficiency of nutrients (N, P)
- Effluents occure in waves with extreme peaks depending
on the weather conditions.
|Plant technology:||During the project
of the airport extension (airport 2000), a
plant was built onsite for highly concentrated deicing solution as
Ecotechnical Sewage Plant by BASE TECH.
|Capacity:||1.700 population equivalents|
|Plant conception:||Storage and purification
of wastewater integrated in the same
plant step saves costs remarkably.
|with COD 45 mg/l far below the imperative.|
|Sewage type:||Deicing fluid|
wastewater purification system including Ecotechnical
Sewage Plant with monitoring and control techniques from BASE TECH.
|Capacity:||4.000 population equivalents|
|Plant conception||Measurement and control techniques separate partial effluent flows depending on the various load degrees, respective to appropriate disposal technique.|
|The COD concentration decreasing to 2% of initial concentration, which is far below the imperative. In addition decomposition of accompanying difficultly degradable substances such as HC, AOX, PAC.|
