Statement of Financial Problem: In November 1985 Paperco was presented with the critical business decision of replacing its existing mechanical drying equipment that had been originally placed into service in 1979 with more efficient equipment provided by Pressco‚ Inc. The consequences of this decision would have far reaching consequences as replacing the equipment could result in cost savings up to $560‚000 annually. However‚ there were other critical factors to address before moving forward with

Assessment Report - Rietspruit WWTW 27-09-2009 The plant currently does not comply with the DWA wastewater discharge standards. There are major challenges with respect to operation‚ maintenance and some equipment status at the plants. Some of the problems identified that are hampering the non-compliance of the final effluents are as follows: • Flow meters are not calibrated (incorrect flow readings) and this makes it difficult to optimize the plant with respect to flows into different modules

Activated Sludge Process will encompass * Design of aeration basins. Relevant design parameters are * BOD load from the upstream process * Mixed Liquor Suspended Solids Concentration (MLSS – mg/l) – typically 2‚000 to 4‚000 * Sludge Age 5 to 25 days * Sludge settleabiltiy (SVI ml/g) typically 100-120 * Process Oxygen Demand (POD) * Generally fine bubble diffusers used in modern plant design – actual oxygen transfer efficiency dependent

Most naturally occurring non-metallic minerals and many manufactured products contain a certain amount of free moisture. Raymond’s technique combines drying and pulverizing in the roller mill which may eliminate independent drying equipment thus reducing capital investment‚ processing time and handling. Heated air or hot waste gas is delivered to the mill return air housing and introduced through air ports to the grinding zone in the mill. The air turbulence and particle size produced during the

CHAPTER 1 INTRODUCTION Background of the Study Solid waste management is increasingly seen as a major issue in the country due to high rates of urbanization and increasing per capita solid waste generation with greater affluence (Petnamsin‚ et al.‚ 2000). A major component of solid waste is resin based plastic. Plastics posses many properties such as water resistance and long life‚ that makes them perfect candidates for packaging. Unfortunately‚ the properties that make this product suitable
