Pretreatment Of Surface Waters On The Example Of A Tributary Of Lake Klasztorne Górne In Strzelce Krajeńskie

The study shows the treatment of river water based on Expanded Clay Aggregate (ECA®). ECA® is lightweight mineral aggregate containing components that enhance phosphorus adsorption (aluminum, calcium, manganese, iron).
A study plant was built on a nutrient rich in Nitrogen(10 mg d/m3) and Phosphorus (0.4 mg d/m3), small, and natural watercourse (Młynówka River, a tributary of Noteć basin, the municipality of Strzelce Krajeńskie).
On the basis of this study, the calculated work-ability/effectiveness of ECA® filters in removing large amounts of contaminants from water was: Nitrogen (6-7%), Phosphorus (10-14%), and for suspensions (12-25%).
The success of the treatment is highly influenced by the hydraulic load.
The ease of operation, simplicity of performance, and low cost of maintenance and construction, the pretreatment plants based on Expanded Clay Aggregate seem to be a promising technique for the protection of surface waters in catchments of streams and small rivers.
