    Badanie odporności membran polipropylenowych na zwilżanie przez emulsje olejowe
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2020-08) Grylewicz, Amanda; Gryta, Marek; Zachodniopomorski Uniwersytet Technologiczny w Szczecinie. Wydział Technologii i Inżynierii Chemicznej. Katedra Technologii Chemicznej Nieorganicznej i Inżynierii Środowiska
    Proces destylacji membranowej (MD) zastosowano do oczyszczania zaolejonych ścieków. W procesie MD woda odparowuje przez niezwilżone hydrofobowe membrany. Zanieczyszczenia organiczne, jak oleje, mogą zwilżać takie membrany. W pracy badano odporność membran polipropylenowych na zwilżanie przez emulsje olejowe.

    Separation of saline oily wastewater by membrane distillation
    (Slovak Society of Chemical Engineering Institute of Chemical and Environmental Engineering Slovak University of Technology in Bratislava, 2019-05-20) Gryta, Marek; West Pomeranian University of Technology in Szczecin
    The presented work is associated with the investigations on the membrane distillation process for the treatment of saline oily wastewaters, such as bilge water. The polypropylene capillary membranes were applied for process study. During the separation of wastewaters the intensive membrane fouling was observed. The formation of deposits on the membrane surface accelerates the pores wettability. It was confirmed, that the degree of membrane wetting in the MD process influences on the purity of obtained distillate. However, the obtained degree of retention for the inorganic compounds amounted to 98% and more than 99 % for the organic compounds.

    Separation of wastewaters from carwash stations by ultrafiltration
    (Slovak Society of Chemical Engineering Institute of Chemical and Environmental Engineering Slovak University of Technology in Bratislava, 2022-05-23) Woźniak, Piotr; Gryta, Marek; West Pomeranian University of Technology in Szczecin
    Carwash wastewaters contain significant amounts of contaminants such as oil and grease, surfactants, solids, nitrogen, and phosphorus. Various treatment technologies have been used for the treatment of these wastewaters. In the present study, the ultrafiltration process was applied for separation of effluents from carwash stations. However, the flux reduction was the significant limitations of the process. Therefore, the efficiency of several methods aimed to reduce the fouling phenomenon was presented.

    Studies of composition variability of oily wastewaters collected from harbour
    (Slovak Society of Chemical Engineering Institute of Chemical and Environmental Engineering Slovak University of Technology in Bratislava, 2019-05-20) Gryta, Marek; West Pomeranian University of Technology in Szczecin
    Effluents from the ships containing the petroleum compounds are very dangerous for the marine environment, hence, they are pre-treated on ships and their concentrates are transferred in harbours for further purification. Oily wastewaters are very difficult for treatment; therefore this process is carried out in specialized wastewater treatment plants. The treatment of oily wastewaters is made a more difficult by the fact that the wastewaters supplied are very different in composition. In this work was carried out the evaluation of variability of the composition of wastewaters collected from oily wastewater treatment plant, which was transferred from a harbour. Several parameters characterizing the actual wastewater (oil content, oil droplet size distribution, pH, salt concentration, surface tension, COD/TOC) were measured. The samples for analysis were collected over a period of 2 months.

    Ultrafiltracja ścieków z myjni samochodowej
    (Oficyna Wydawnicza Politechniki Wrocławskiej, 2022-05-11) Woźniak, Piotr; Gryta, Marek; Sałacińska, Amanda; Zachodniopomorski Uniwersytet Technologiczny w Szczecinie. Wydział Technologii i Inżynierii Chemicznej
    Podczas mycia samochodów powstają niebezpieczne dla środowiska ścieki. W pacy zbadano ich oczyszczanie z użyciem ultrafiltracji. Badano membrany PES o wartości cut-off 10 i 100 kDa.
