Tytuł:: Analysis of COD Fractions in Raw Wastewater Flowing into Small and Large Wastewater Treatment Plants

Tematy:: COD fractions
treatment plants

constructed wetland
activated sludge
Opis:: The aim of the study was to determine and compare the amount and biodegradability of organic compounds determined by the COD measure contained in raw sewage inflowing to small sewage treatment plants and municipal sewage wastewater treatment plants with high personal equivalent (P.E.). Raw sewage samples were collected in three chosen facilities. The research presented in the article were conducted with two small plants: constructed wetland plant with an average capacity of 4 m³/d and the treatment plant with rotary biological contactor (RBC) with an average capacity of 5 m³/d. Also big municipal wastewater treatment plant (WWTP) with activated sludge in Bialystok with a capacity of about 63 000 m³/d was checked. The lowest percentages of dissolved fraction of soluble organic non-biodegradable substances S_I was founded in raw sewage in small wastewater treatment plants (CW and RBC).

Tytuł:: Assessment of the Quality of Wastewater Generated During Production at a Tannery Plant
Autorzy:: Dziadel, Maciej
Ignatowicz, Katarzyna
Powiązania:: https://bibliotekanauki.pl/articles/2086409.pdf
Data publikacji:: 2022
Wydawca:: Polskie Towarzystwo Inżynierii Ekologicznej
Tematy:: industrial wastewater
tannery
chrome
Opis:: The aim of the study was to determine the composition of wastewater generated in a small tannery plant in the Podlaskie Province at different stages of the technological process. Since the plant uses chromium salts for the actual tanning process and the resulting wastewater is separated into two streams, it was possible to determine the content of chromium and other pollutants in the wastewater at different stages of the production processes. This allowed us to evaluate the biodegradability of the wastewater produced during production, the concentration of chromium compounds and other contaminants. Based on the results obtained, the wastewater generated during the production process was found to be non-biodegradable (except for the mixed wastewater) with chromium concentrations of 2.0–2.46 g/dm3.

Tytuł:: Effect of Dosing PIX 113 Coagulant to the Batch on Mesophilic Fermentation Process and Reducing Hydrogen Sulfide Content in Biogas
Autorzy:: Kozłowski, Dariusz
Ignatowicz, Katarzyna
Powiązania:: https://bibliotekanauki.pl/articles/2202255.pdf
Data publikacji:: 2022
Wydawca:: Polskie Towarzystwo Inżynierii Ekologicznej
Tematy:: ferric coagulant
sulfur
PIX
biogas treatment
hydrogen sulfide
Opis:: In certain concentrations, hydrogen sulfide – occurring in gaseous fuel – corrodes combustion chambers, contaminates and acidifies engine oil and has a destructive effect on engine seal components, valve seats and timing. Fuel in the form of digestate gas, before powering cogeneration units, must meet the standards set by the manufacturer of the unit. Whether such values can be achieved depends primarily on the concentration of hydrogen sulfide and the desulfurization method used. The purpose of the study was to determine the effectiveness of sulfur fixation in the sludge by dosing the PIX 113 coagulant directly into the feedstock before pumping into the chamber. The results obtained confirmed the effectiveness of the coagulant and provided the basis for conducting further studies using other products based on iron compounds. During the experiment, there were no negative effects of applying the coagulant to the batch just before pumping into the chamber. The positive aspects of sludge supplementation with the tested agent included an increase in biogas production due to a decrease in the H2S concentration and an improvement in biogas quality parameters – CH4 and CO2.

Tytuł:: Removal of Pesticides from Wastewater by the Use of Constructed Wetlands
Autorzy:: Ignatowicz, Katarzyna
Puchlik, Monika
Łozowicki, Jakub
Powiązania:: https://bibliotekanauki.pl/articles/125196.pdf
Data publikacji:: 2020
Wydawca:: Polskie Towarzystwo Inżynierii Ekologicznej
Tematy:: constructed wetland
organic matter
pesticides
Opis:: The purpose of the work was to determine the efficiency of domestic wastewater treatment contaminated with a mixture of pesticides at varying deposit load. The efficiency of purification in the case of eight pesticides equaled 99.8%, and the removal effect of azoxystrobin reached 93%, while that of thiachloprid – 96%. The constructed wetland ensured high removal of organic matter expressed as BOD and COD, as well as reduction in the concentration of nitrogen and phosphorus compounds. Studies showed a clear impact of the deposit load on the effectiveness of pesticide removal, BOD and COD parameters, total phosphorus, and total nitrogen.
