factor affecting the design of thickener

The high time for thickeners was in the 60's when the metallurgical industries were booming and sizes of up to 150 m diameter were constructed Such jumbo thickeners, when centrally driven, require for most demanding applications extra heavy duty drive heads some of which reach a continuous operating torque of 3 300 000 Nm

Primary cementing The objective of primary cementing is to provide zonal isolation Cementing is the process of mixing a slurry of cement, cement additives and water and pumping it down through casing to critical points in the annulus around the casing or in the open hole below the casing string

Nov 06, 2010 Various factors affect gel formation by hydrocolloids which include concentration of the gelling agent, pH of the medium, molar mass/degree of polymerization, temperature, ionic composition and solvent quality Walstra 2003 Typically used gelling concentrations of different hydrocolloid gelling agents in food are summarized in Table 3

The increase in flocculation efficiency realised in high rate thickeners may increase in a bulk settling rate 2 to 10 times over that obtained in a conventional thickener, thus reducing the unit area requirements by a similar factor The corresponding volume may be 4 to 15 times smaller than with conventional thickeners in the same application

Structural engineering depends upon a detailed knowledge of loads, physics and materials to understand and predict how structures support and resist self weight and imposed loads To apply the knowledge successfully structural engineers will need a detailed knowledge of mathematics and of relevant empirical and theoretical design codes They will also need to know about the corrosion

Factor of Safety: Normally a 25 per cent factor of safety is allowed in determining the thickener area size Thus, in the above case, 8 87 largest of three figures plus 25 per cent factor of safety, equals 11 09 square feet area required per ton of dry solids fed to the thickener per 24 hours
