This study was conducted to assess the ability of the studied adsorbent, i.e. raw oak fruit hulls and the activated carbon prepared from oak fruit hull for removing the Methylene blue (MB) from aqueous solution. This study was conducted under various effective parameters, e.g., contact time, pH, MB concentration, adsorbent concentration. The optimum amount of each parameter was determined a...

activated sludge or extended aeration treatment involves a continous system where aerobic biological growths are mixed with waste water and then separated in a gravity clarifier. therefore, waste treatment system such as the activated sludge system depend on the activities of communities of living organism. in this study, an attempt was made on the indentification of the bacterial population in...

Background: One of the possible carcinogenic substances found in foods is Acrylamide (AA). This study aims to combine and innovate sea grapes (Caulerpa racemosa) extract with activated carbon into paper towels that can absorb AA levels in fried foods. Methods: The paper towel was created with composition of activated carbon: sea grapes extract: paper pulp using following formula: F0=0:0:100; F...

to day, the activated carbon is being used to treat the industrial and domestic wastewaters. the suitability of activated carbon for treatment of industrial wastewaters can be quickly predicted by consideration of wastewater characteristics. the results of this paper represent a first step in determining suitability of activated carbon for treatment of wastewaters or effluent of treatment plant...

in the temperature range of 10 to 80 ºc and in a batch digester, a typical activated sludge was digested aerobically. reaction rate constants were determined by measuring the amounts of volatiles removed from the suspended solids at different time intervals during the process. the maximum value of the reaction rate constant (0.45 d-1) occurred in the temperature range of 55-60˚c. removal of ind...

conclusions our study demonstrated the efficacy of rfviia in controlling postoperative bleeding in redo cardiac valve surgeries regarding subsequent blood loss and transfusion requirement; however, outcome results remains to be defined. results study groups showed no difference regarding baseline variables. three patients in rfviia group (16.67%) and 13 in placebo group (72.23%) received blood ...

this study evaluated the effects of 0.25% activated charcoal added to sesame seed meal (ssm) in partial replacement of soybean meal (sbm) of juvenile clarias gariepinus diet on growth and haematological parameters for 70 day experimental period. six experimental diets were formulated as: control diet 1 (100% ssm without activated charcoal), control diet 2 (100% ssm plus 0.25% activated charcoal...

the objective of this study was to assess the adsorption potential of activated carbon (ac) asan adsorbent for the removal of murexide (mu) from aqueous solutions. the influence of variablesparameters including ph, amount of adsorbent, sieve size of adsorbent, temperature and contact timeon mu removal was studied. following optimization of variables, the relation between concentrations ofdye re...

sepsis as the host responsive syndrome is one of the main concerning issues and costly disease on intensive care unit (icu) in the 21st century. epidemiological studies have showed that mortality rates of sepsis in icu and hospitals among 37 countries were 39.2% and 49.6% respectively [1].  complicated nature of sepsis is still not well understood and this makes it hard to treat and manage. acc...
