As part of the delivery for the first expansion stage of the Czajka wastewater treatment plant in Warsaw/Poland, BUTTING was given a new order to manufacture aeration panels to complete the plant. After only two years, the project for modernising and expanding the Czajka wastewater treatment plant at the gates of the Polish capital is due for completion at the end of 2010. This will increase the amount that can be cleaned from 240,000cum to 450,000 cum a day. As part of the first expansion stage of the wastewater plant, BUTTING fitted the first six of a total of ten aeration basins with panels at the end of 2009. The stainless steel processor’s scope of delivery consisted of a large number of pipe parts manufactured according to special customer drawings. The family company processed more than 350tn made from the materials 1.4571 and TP316L. BUTTING also supplied for the second expansion stage. A further four aeration basins will be equipped with panels by the end of 2010. In manufacturing them, the company manufactured the pipes, elbows, collars, lapped flanges, sleeves and circular blanks, all in nominal widths of DN 80, DN 100 and DN 250. The specialist processing of stainless steels supports the pipe system in functioning securely on a long-term basis and minimises the investment and maintenance costs of the Czajka wastewater treatment plant.
