(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 1996)It was found that aluminum sulfate reacts with potassium chloride to produce K2SO4, Al2O3, and Cl-2 in the solid phase at 700 degrees C. This reaction was investigated with thermal analysis under air and nitrogen atmosphere. ...
-
(ELSEVIER SCIENCE SA, 1997)The corrosion behaviour of ceramics and cermet coatings on AISI 304L steel substrates was investigated in several aqueous solutions. Plasma spray process was employed on substrates with the deposition of ceramic and cermet ...
-
(MANEY PUBLISHING, 1999)The dissolution of calcined alunite ore in NaOH solution was studied at temperatures ranging between 295-383 K. The effects of ore calcination time and temperature, reaction time and temperature, particle size and solid-liquid ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2000)For evaluating the tannin (natural polyelectrolyte) and AN913 (synthetic anionic polyelectrolyte) as a coagulant aid For treating raw water to remove suspended matter the tannin or AN913 was added to the synthetic water ...
-
(KLUWER ACADEMIC PUBL, 2002)Dyestuff production units and dyeing units have always had a pressing need for techniques that allow economical pretreatment for color in the effluent. The effectiveness of adsorption for dye removal from wastewaters had ...
-
(ELSEVIER SCI LTD, 2003)This paper describes a new autoignition submodel for engine modeling codes. This submodel does not require extensive computational resources and is easily portable to various computational environments. It also considers ...
-
(ELSEVIER SCIENCE BV, 2003)dAn attempt to alleviate the problem caused by the presence of reactive dyes in textile effluents was undertaken. Since alunite is a very abundant and inexpensive, we decided to experiment with it as a potential adsorbent ...
-
(ELSEVIER SCIENCE BV, 2003)Aluminum sulfate, alum, is a common chemical coagulant used for coagulation. Recently, polymers have been utilized in coagulation/flocculation processes for water purification. In this study, the ability of two organic ...
-
(MARCEL DEKKER INC, 2003)Raw mixed pharmaceutical industry and domestic wastewater characteristics are such as BOD5 = 90-130 mg L-1, COD = 200-300 mg L-1, SS = 900 mg L-1, PH = 6.4-6.8, T = 20degreesC, NH3=26 mg L-1, PO43- = 8.5 mg L-1. In treatment ...
-
(ELSEVIER SCIENCE BV, 2003)Tannin is a biodegradable anionic polymer. Tannin as a coagulant aid can be a potential substitute for synthetic anionic polyelectrolytes in water treatment because it can: (1)avoid the health effects from residual ...
