Ultrasonic treatment of baker's yeast effluent using SnO2/TiO2 composite
(De Gruyter Open Ltd, 2017)
In this study, ultrasonic treatment of baker's yeast effluent was investigated in an ultrasonic homogenizer emitting waves at 20 kHz. The SnO2/TiO2 composites were used as a sonocatalyst to assist the sonication process. ...
Dewatering of barite clay wastewater by inorganic coagulants and co-polymer flocculants
(Oficyna Wydawnicza Politechniki Wroclawskiej, 2015)
This work is focused on dewatering of barite-containing clay waste from a barite beneficiation plant by coagulation and flocculation to enhance the dewatering rate and recycling of process water. A flocculation performance ...
An evaluation of a modified product size distribution model based on t-family curves for three different crushers
(Oficyna Wydawnicza Politechniki Wroclawskiej, 2013)
Crushing is a process which is widely used in mineral processing plants, cement factories, aggregates plants and some other industrial plants. Specific fracture energy of the particles is not the only fundamental property ...
Effects of flexural stiffness, axial velocity and internal support locations on translating beam's natural frequencies
(Trans Tech Publications, 2014)
The aim of this paper is to examine the natural frequencies of beams for different flexural stiffness, internal simple support locations and axial moving speed. In the present investigation, the linear transverse vibrations ...
Flocculation of fine particles in ceramic wastewater by using polymers
(Polish Mineral Engineering Society, 2014)
The clarification of industrial wastewaters by solid-liquid separation techniques and the removal of suspended particles are the problems of growing environmental consciousness. However, there appears to be very limited ...
The effects of ball types on breakage parameters of barite
(Polish Mineral Engineering Society, 2014)
Spherical balls are the dominant media shape used in the tumbling mills. However spherical balls wear into nonspherical fragments as a result of breakage due to impact and different wearing mechanisms inside the mill. Thus ...
Optimization of coal flocculation with an anionic flocculant using a Box-Wilson statistical design method
(Oficyna Wydawnicza Politechniki Wroclawskiej, 2014)
In this study, the Box-Wilson statistical experimental design method was employed to evaluate suspension pH, salt (CaCl2·2H2O) concentration and anionic flocculant (A-150) amount in flocculation of coal. Response function ...
High temperature wear behavior of the surface-modified externally cooled rolls
(Elsevier B.V., 2018)
Externally cooled rolls of a steel plant were coated using three different surface modification techniques, namely titanizing, boronizing and borotitanizing. The grown coatings were examined using optical microscopy, ...
Sno2/graphene nanocomposites with enhanced gas sensing performance
(Trans Tech Publications Ltd, 2018)
Graphene-Tin Oxide (G-SnO2) nanocomposites in different morphology were synthesized using tin (II) chloride (SnCl2) and graphene Oxide (GO) via hydrothermal process in the presence of hydrazine and ammonia by adding ...
The effect of potassium modification on structural properties and catalytic activity of copper and iron containing SBA-16 catalysts for selective oxidation of ethanol
(Elsevier Ltd, 2019)
Copper and iron SBA-16 catalysts were synthesized using hydrothermal method and modified with potassium. XRD patterns showed that characteristic peaks of SBA-16 for all catalysts did not destroy with metal loading. The ...
