Obecnie kontrola dopłat bezpośrednich do rolnictwa dotyczy weryfikacji wielkości upraw oraz zachowania odpowiedniej kultury rolnej. Wielkość upraw, określana jest przy użyciu ortofotomapy o niskiej stosunkowo rozdzielczości, odzwierciedlającej stan sprzed kilku lub kilkunastu miesięcy, a nawet lat. Permanentne żądania Komisji Europejskiej dotyczące zwrotu środków przeznaczonych na dopłaty do polskiego...
Our paper presents the results of investigations on the treatment of waters involved in unit process ultrafiltration, hybrid process - coagulation/sedimentation/ultrafiltration and in-line coagulation/ultrafiltration. In membrane filtration that we applied immersed capillary membranes. Simulated water containing humic acids at 30 mg/l was ultrafiltered with a constant volumetric permeate flux amounting...
This work presents the verification of the model of the membrane filtration process of natural waters for non-stationary filtration flux J=f(t), as well as the results of tests involving the filtration process of the said model in constant pressure conditions. Also, the characteristic time of permeate flux decay was determined, and the mechanisms reducing the efficiency of filtration process were...
Among all the technologies of water treatment, membrane technology appears to be the most promising. The major advantage of this technology is its ability to produce water with a constant and well adjusted quality. Moreover, membranes remove a wide range of substances, ranging from particles to ions, including bacteria and viruses, and they can operate without any chemical addition to raw water. The...
