Physical properties of sand from the waste water treatment plants

Abstract

VÍTĚZ, T., KUKLA, R., TRÁVNÍČEK, P.: Physical properties of sand from the waste water treatment plants. Acta univ. agric. et silvic. Mendel. Brun., 2010, LVIII, No. 4, pp. 233-238 The work is focused on characterization of selected physical properties of sewage sand from the waste water treatment plants. Sand is transported into wastewater mainly in areas with a combined se we ra ge system -principally in connection with rainfalls, in case of which it is transported through the sewerage system together with rainwater, but also (within smaller extents) due to leakages of sewerage systems or bad conduct of natural persons and legal entities. The main attention was focused on basic physical parameters such as content of total solid, ash free dry mass, density and granulometry. These material parameters are very o en underestimated so the set of quality data is completly missing, as well as a background for designers of wastewater treatment plants. This paper should be quite useful e.g. for the purpose of technological equipment design in the region of South Moravia.sand, waste water treatment plant, density, granulometry

Geotechnical Properties of Washed Mineral Waste from Grit Chambers and Its Potential Use as Soil Backfill and Road Embankment Materials

“…Moreover, most papers concern only mineral waste characterization and grit chamber performance evaluation, with a significant proportion being site-specific [14]. Hence, the main purpose of studies is usually to optimize the design guidelines of grit chambers for mechanical wastewater treatment and their technological processes [14][15][16][17][18][19]. The papers [15,19] also present an additional purpose, which is to consider the possibility of processing and using mineral waste in construction.…”

The papers [15,19] also present an additional purpose, which is to consider the possibility of processing and using mineral waste in construction. The conducted research focuses on determining the physical properties of mineral waste in terms of dry matter content, the content of organic and inorganic substances, granulometric composition, specific density and the settling velocity of particles in grit chambers [14][15][16][17][18].…”

“…The sieving and sample pretreatment methods used to characterize wastewater sand particles are also included in [17]. The authors of papers [14][15][16][17][18][19] state that the measurements of the physical properties of mineral waste have been neglected for a long time.…”
