A Unique Application Methodology for the Use of Phosphorus Inactivation Agents and Its Effect on Phosphorus Speciation in Lakes with Contrasting Mixing Regimes

The efficiencies of the restoration two lakes varied morphometries and trophic states—meromictic, hypertrophic Lake Klasztorne Ma?e, dimictic, eutrophic Du?e—with use phosphorus inactivation method with sequential application iron aluminum compounds have been compared. total dose agents applied for Ma?e was 38 tons PAX 18 (aluminum polychloride) 14 PIX 111 (iron chloride), Du?e, it 74 46 111. After compounds, better efficiency phosphate removal from surface water layers obtained in case Du?e. doses did not lead to complete precipitation phosphates bottom either lake. It is noteworthy that both lakes, inhibition internal loading process observed. results showed types makes possible reduce cost restoration, moreover, dosing salts coastal areas ensures a higher level ecological safety.
