Monitoring of the Gjanica river, egel line, contamination from the oil industry and urban areas (Ballsh-Fier, Marinze) until the connection with the Seman river
The monitoring was conducted at 24 Sampling Sites: 13 along the Gjanica River and 11 along the Ngjala Line up to the confluence with the Seman River.

DIFFERENT TECHNOLOGIES FOR TREATMENT OF DISCHARGES FROM THE OIL EXTRACTION AND PROCESSING INDUSTRY
DEPENDING ON THE OIL THAT THEY CONTAIN, OIL WATER IS DIVIDED INTO THESE CATEGORIES:
- Water with oil content 5-20 mgr / 1. (Oil is found dissolved)
- Water with oil content 20-50 mgr / 1. (Oil is in the form of a floating membrane)
- Water with oil content 50-100 mgr / 1. (Oil is in emulsion form)
- Water with oil content 100-500 mgr / 1. (Oil is in the form of chips and emulsion)
PHYSICO-CHEMICAL TREATMENTS OF POLLUTANTS
- OZONE METHOD
- BURNING METHOD AND REVERSE OSMOSIS
- ION EXCHANGE METHOD
