Inactivation of phosphorus in two shallow lakes by means of PROTEfos prof. Ryszard Winiewski dr Przemysaw Nowacki mgr in. Adrian Szulczewski Slide 2 Innovation of our method and comprehensiveness of services provided by us. Innovation technology of blocking phosphorus directly in bottom sediment (the core of our service). Comprehensiveness using many different and individualy selected supportive methods around the core one. Our method is patented. Slide 3 Visualization of the inactivation process Slide 4 Two-unit vessel for phosphorus inactivation in bottom sediments surface unit. Slide 5 Two-unit vessel for phosphorus inactivation in bottom sediments underwater unit.

Slide 11 Dosing chemical substances First stage was the dosing of ferric chloride from the surface to precipitate the suspended matter and to bind the phosphorus from water and ground it within the bottom of the lake. Second and main stage was the dosing of appropriate chemical substances into bottom sediment of the lake. Launching additional supportive methods. Slide 12 Undertaken Actions analysis and monitoring.

Slide 14 Undertaken Actions using barley straw. Decomposition of barley straw causes release of chemical substances called algaestatics reducing the growth of algae, including blue-green algae Straw used for this purpose was formed in bricks about 10 kg each. Overall, there were 600 of such straw bricks installed on both lakes. Slide 15 Undertaken Actions deployment of barley straw. Jelonek WiniaryPond Slide 16 Undertaken Actions deployment of barley straw. Slide 17 Undertaken Actions biomanipulation (changes in fishstock). 263 kg of fish were caught in Lake Jelonek. 10% of them were predatory fish (pike, zander). 90% were the so called white fish (crucian carp, prussian carp, carp beam, tench). In Lake Winiary 290 kg were caught. 28% constituted predatory fish (zander, pike, perch) and 72% constituted white fish (prussian carp, carp, carp beam. The two lakes were also stocked with Autumn and Spring fry of pike in the following quantities: -Lake Jelonek 250 kg i.e. 1250 pcs. + 10,500 pcs. -Lake Winiary 300 kg i.e. 1500 pcs +11,500 pcs. Slide 18 Undertaken Actions biomanipulation (changes in fishstock). Slide 19 Slide 20 Slide 21 Undertaken Actions reintroduction of macrophytes (Lake Winiary). wosienicznik rdestnica kdzierzawa Slide 22 Undertaken Actions reintroduction of macrophytes. The following species of submerged plants were introduced in Lake Jelonek in the years 2009-2010: - Myriophyllum spicatum - 500 pcs., - Ceratophyllum demersum - 500 pcs., - Potamogeton lucens - 500 pcs., - Elodea canadensis - 500 pcs. - Stratiotes aloides - 500 pcs., - Nitellopsis obtusa - 2700 pcs. As well as other species of plants with floating leaves (planted in bunches about 10 pcs. each) : - Typha latifolia - 25 bunches + 200 pcs., - Nuphar luteum- 10 bunches, - Butomus umbellatus - 5 bunches + 100 pcs., - Schoenoplectus lacustris- 5 bunches, - Iris pseudacorus - 5 bunches + 100 pcs., - Hipperius vulgaris - 100 pcs. Overall quantity of macrophytes and macroalgae planted on both lakes and the pond reaches 7050 pcs. (in the years 2009-2010). Slide 23 Results increase of water transparency Average from 97% (Winiary) to 103% (Jelonek) - max. 1,1 4m. 2009 - IX 2010 - IX sampling points 1w 2w 3w 1j 2j 3j Slide 24 Results decrease of total phosphorus in water Average from 55% (W) to 58% (J). 2009 - IX 2010 - IX sampling points 1w 2w 3w 1j 2j 3j Slide 25 Results decrease of chlorophyll a Average from 52% (J) to 67% (W).
