Level and limit level detection with ProGap - Case Study

Application During the process of mining gypsum in a stone quarry, gypsum rock is transported via a series of conveyor belts to the production line. Certain critical conveyors are located remotely from the production line and therefore not visible and suspect to blockages. The customer wants to avoid material overfl ows and blockages between the conveyor belts and a transition chute. Because of ...

Schedule performance measurement based on statistical process control charts

In a job–shop environment, achieving a schedule that is on target is difficult due to the dynamism of factors affecting the system. In this paper the Shewart's Individuals control chart is applied to a scheduling process for the purpose of measuring schedule performance. The charts are applied to monitor the deviations of actual from scheduled process times for jobs on a process machine. Data ...

Participation and environmental assessment in Northern and Southern cities, with examples from Stockholm and Jakarta

Increasing public participation in environmental assessment is a common goal, North and South. Despite a relative lack of formal education and institutionalised democracy, participatory appraisal has become far more popular in low-income areas in the South, where many advocates claim that it is possible to give local residents a large measure of control over both the research process and its ...

Implementation of a process internal control to monitor the performance of real-time PCR assays for the detection of <italic>Vibrio cholerae</italic> in water

Implementation of a process internal control to monitor the performance of real-time PCR assays for the detection of Vibrio cholerae in water

The process control utilised in this study was an Escherichia coli (E. coli-GFP) strain carrying a chromosomally integrated copy of the green fluorescent protein (gfp) gene of the jelly fish Aequorea victoria. Application of the process control involved spiking samples with the E. coli-GFP containing cells and detecting gfp using real-time polymerase chain reaction (PCR). The process control ...

Minimizing risks in wastewater reuse: proposed operational principles and guidelines for South Africa

Treated wastewater represents a significant potential source of reclaimed water for some beneficial reuses. However, public concern over the risks/health-related hazards of wastewater reuse has limited the general acceptability of reuse systems in many countries. It is important to manage the operation of recycled water systems in such a way that it will not adversely affect public health and ...

A Treatise on Turbidity and TSS

When two distinct physical parameters are used interchangeably, an intimate understanding of both is in order to know when this is justifiable. Two such parameters are turbidity and total suspended solids. In many industries today the concentration of total suspended solids is of utmost importance to quality control and process optimization. However, the measurement most often employed is ...
