Abstract
The shape of granular particle from a filter layer represent a determinant factor regarding the efficiency of filtration process. In order to adequately predict the efficiency of granular filters is necessary to know the distribution of granular particle shape from filter layer. This paper presents a small study - in terms of experimental results, but laborious - in terms of sample preparation, regarding the identification of distribution by shape classes of granular particles from a filter layer. For experimental determinations have been used perlite and anthracite - two granular filter materials. It has been analyzed in terms of particle shape 1,000 particles of perlite and 1,000 particles of anthracite taken randomly from each filter layer. It has been observed that spherical particles have an average distribution for two type filter materials.
Highlights
The systems which involve interaction between liquid and solid granular particles are frequently encountered in practice, being widely used especially in industrial processes [1,2,3,4,5].One of the most common two-phase systems liquid - granular particles is represented by filter layer used in processes such as water or wastewater treatment [6, 7]
In order to determine the distribution of granular particle shape in the filter layer have been chosen two kinds of filter materials used in particular for water treatment and wastewater treatment: perlite and anthracite [12, 13, 22]
In order to know the distribution of the granular particle shape from the filter layers were carried out determinations for 1,000 perlite particles and for 1,000 anthracite particles
Summary
The systems which involve interaction between liquid and solid granular particles are frequently encountered in practice, being widely used especially in industrial processes (chemical and biochemical industry, food industry, pharmaceutical industry, detergent industry, mining, water and wastewater treatment) [1,2,3,4,5]. One of the most common two-phase systems liquid - granular particles is represented by filter layer used in processes such as water or wastewater treatment [6, 7]. Wakeman demonstrated in an experimental study that the shape of granular particle from a filter layer primarily affects the volume and surface area of the particles, and their specific surface and the rate of fluid flow through formed filter cakes [11]. The author has conducted an experimental study using granular particles with perfect form (cubic, rectangular, spherical, fibrous, cylindrical and flakey) [11]
