Algal treatment of pulp and paper industry wastewaters in SBR systems
Tarlan, E; Yetiş, Ülkü; Dilek, Filiz Bengü (2002-01-01)
Highly colored and highly polluted pulp and paper industry wastewaters are proposed to be treated by using algae in sequential batch reactors (SBR). Results of batch studies revealed that up to 74% COD; 74% color removal could be attained in about 40 days of incubation, From the preliminary SBR experiments, filling period was found to be a critical step affecting the overall efficiency when mixing and aeration is applied during filling. Therefore, 5 different filling periods (4, 6, 8, 10 and 12 days) were s...

Alkali activation of a slag at ambient and elevated temperatures
Altan, Ekin; Erdoğan, Sinan Turhan (2012-02-01)
Strength development of alkali activated slag (AAS) mortars, activated using alkali hydroxide and sodium silicate, was investigated at room and elevated temperatures. Heat evolution at room temperature was measured using isothermal calorimetry. Important differences were observed between critical activation parameters. Heat cured specimens gain strength rapidly, humid oven conditions being favorable, but given sufficient time room temperature curing yields comparable strengths. Both activators are needed fo...
Alkali reactivity of mortars containing chert and incorporating moderate-calcium fly ash
Bektas, F; Turanli, L; Topal, Tamer; Göncüoğlu, Mehmet Cemal (2004-12-01)
This paper reports the results of an experimental program, which aimed to investigate the alkali reactivity of chert and the effect of a moderate-calcium fly ash on the alkali-silica reaction. To determine the expansions, mortar bars were cast and tested in accordance with ASTM C1260. Mortar aggregate was replaced by chert, in controlled amounts, to find out the pessimum limit, if any. To evaluate the degree of cracking, sonic pulse velocity measurements and petrographic analysis were carried out on the cra...
