Opis:: Potentially negative environmental and human health effects have led to pharmaceutical chemicals,which are labeled as a new class of environmental contaminants. Adsorption is one of the most appealing choices to remove that pharmaceutical waste in recent years. However, the environmental limitations of the adsorbent material are an obstacle to the development of this process. The current study suggested the remaining Chlorella vulgaris biomass, after the extraction process of the biomaterials, to be a bio-absorption material in removing the Ciprofloxacin from the hospital wastewater. The preparation and characterization of the suggested adsorbent through FTIR analysis, and scanning electron microscopy, coupled with energy-dispersive X-ray spectroscopy and X-ray diffraction, were present in the current study. Several functional groups (such as carboxylic, amines, hydroxyls, and amides) were observed to aid the adsorption process. After the extraction process, the results showed a growth in the peaks, indicating an increase in functional groups, particularly the -O.H. and -N.H. groups, while having changed toward lower energy after binding with CIP atoms, as well as an increase in surface area from 2.3723 to 3.6224 m2/g. The XRD was shown to be compatible with the EDX test, which both demonstrated a decrease in carbon element concentration due to the deconstruction process. The effects of Ciprofloxacin bio-sorption variables, including contact time, initial Ciprofloxacin concentration, pH, and adsorbent dosage, were adopted as a parametric study. The maximum adsorption capacity was recorded at pH 7 with an adsorbent dose of 2.75 g/L; after 120 minutes, the data show that 89.9% of Ciprofloxacin has been adsorption onto the extracted biomass.

Opis:: The objective of this study was to determine the possibility of using a liquid waste fraction generated in the process of bioethanol production from sugar beets for biomass production from Chlorella vulgaris microalgae. The process of microalgae culture was conducted in three variants differing in the volume of the liquid phase fed to the technological system. The highest technological effects in biomass growth were noted in the experimental variants in which the distillery stillage constituted 5% and 7% of culture medium volume. Concentration of biomass achieved in these variants reached 1416±45.30 mgo.d.m./dm3 and 1458.3±54.52 mgo.d.m./dm3 , respectively. Increasing the content of the liquid waste fraction in the medium to 10% caused significant growth inhibition of biomass of algae from the species Chlorella Vulraris. The use of such a culture medium for microalgae biomass production requires its pre-treatment to remove organic compounds, color and turbidity.

Opis:: The objective of the paper was to analyse the use of the designed photobioreactor for freshwater microalgae cultivation in the controlled laboratory conditions. The work covered the design and construction of photobioreactors (PBR) and setting up comparative cultivations of freshwater microalgae chlorelli vulgaris along with determination of the biomass growth intensity for a varied amount of supplied culture medium. It was found out that the constructed PBR may be used for microalgae cultivation in the controlled conditions. The impact of the culture medium amount on the growth of chlorelli vulgaris was proved. As a result of the increase of culture medium concentration to 30.1-120.4 ml·l-1 of water, dry mass in photobioreactorsincreased respectively from 1.33 g·dm-3 to 4.68 g·dm-3.
Celem pracy była analiza możliwości wykorzystania zaprojektowanego fotobioreaktora do hodowli mikroglonów słodkowodnych w kontrolowanych warunkach laboratoryjnych. Zakres prac obejmował projekt i wykonanie fotobiorekatorów (PBR) oraz założenie hodowli porównawczych mikroglonów słodkowodnych chlorelli vulgaris wraz z określeniem intensywności przyrostu biomasy dla zmiennej ilości dostarczanej pożywki. Stwierdzono możliwość zastosowania zbudowanych PBR do hodowli mikroglonów w kontrolowanych warunkach. Wykazano wpływ ilości pożywki na rozwój chlorelli vulgaris. W rezultacie zwiększenia stężenia pożywki od 30,1-120,4 ml·l-1 wody, nastąpił w trakcie trwania doświadczenia przyrost masy suchej pozostałości w fotobioreaktorach odpowiednio od 1,33 g·dm-3 do 4,68 g·dm-3.

Opis:: The paper shows the possibility of using chlorophyll-synthesizing microalgae of Chlorella vulgaris to purify biogas from carbon dioxide (CO2), hydrogen sulfide (H2S) and ammonia (NH3). Experimental dependences of the dynamics of CO2 uptake by microalgae under the action of H2S inhibitor and NH3 activator were presented. A mathematical description of the growth of biomass of microalgae Chlorella vulgaris, depending on the concentration of hydrogen sulfide and ammonia, was obtained. The optimal values of hydrogen sulfide and ammonia concentration for the efficient process of carbon dioxide uptake by chlorophyll-synthesizing microalgae Chlorella vulgaris from biomethanization gas were established.

Opis:: Wastewater that contains high concentration of nutrients can create instability in water ecosystem if left untreated. Laundry wastewater contains nutrients in high concentration. The nutrients that commonly found in laundry wastewater are nitrogen and phosphorus. This study had a purpose to determine the effect of illumination period and light intensity for the removal of Chemical Oxygen Demand (COD), Nitrogen-ammonia (NH₃-N), and phosphate (P) content using Chlorella vulgaris in High Rate Algal Reactor (HRAR) treatment. Variables that used were exposure period of 12 and 24 hours and light intensity of 2000–3000 Lux, 4000–5000 Lux, and 6000–7000 lux. The parameters tested to determine the efficiency of nutrient removal were COD, Nitrogen-ammonia, phosphate and Chlorophyll α to determine the condition of algae development. The results showed that the highest nutrient removal were obtained by the reactor with 24 hours illumination period with light intensity of 6000–7000 Lux that was capable of removing 54.63% of COD, and 22.15% of P. The 12-hour illumination period was better in terms of NH₃-N removal, up to 50.07%. On the basis of the of statistic test result, the illumination period did not significantly influence the removal efficiency of COD, NH₃-N and P indicated by P-value >0.05, while the light intensity significantly affect the removal of COD and NH₃-N showed by P value <0.05.
