Biologiczne sposoby usuwania zanieczyszczeń z grupy emerging contaminants podczas oczyszczania ścieków

Zając A., Kruszelnicka I., Ginter-Kramarczyk D., Zembrzuska J.

Przemysł Chemiczny

2016

T. 95, nr 2

263--268

Podjęto próbę zdefiniowania pojęcia emerging contaminants oraz contaminants of emerging concern zarówno w kontekście rodzaju substancji zaliczanych do tej grupy, jak i przyczyn oraz źródeł ich powstawania. Zaprezentowano biologiczne metody oczyszczania ścieków z wykorzystaniem mikroorganizmów osadu czynnego a także ich skuteczność w usuwaniu zanieczyszczeń z grupy emerging contaminants.

A rewiew, with 26 refs., of methods for removal of pharmaceuticals.

Biofilm development on acrylic coupons during the initial 24 hour period of submersion in a tropical coastal environment

Satheesh S., Wesley S.G.

Oceanological and Hydrobiological Studies

2010

Vol. 39, No.1

27-38

The sequence of biofilm formation on a hard surface during the first 24 hours in a coastal environment was studied by suspending acrylic coupons. Adsorption of carbohydrates, proteins, calcium, magnesium, nitrite, nitrate and phosphate were monitored along with microbes. The results showed that carbohydrate, protein, nitrite and nitrate were adsorbed on the coupons within an hour of exposure. Carbohydrates showed a maximum value of 0.28 mg cm-2 after 24 hours and protein concentration reached up to a maximum of 0.41 mg cm-2. Adsorption of calcium and magnesium was observed after three hours. Settlement of bacteria was also observed on coupons within an hour and diatoms were observed after 15 hours. Diatoms such as Navicula and Nitzschia were the dominant colonizers during the early stages of biofilm development.
