A collection of case studies that highlights new products in action and how vendors help chemical manufacturing companies succeed.
A start-up is only as easy as the preceding steps: construction and commissioning, says Senior Editor Dirk Willard in his monthly column.Click Here
In industrial processing plants, a DAF is often used to reduce loadings and clarify wastewater. Tiny air bubbles are released into the tank causing small particulates to float to the top where they are skimmed off. To remove larger suspended solids, coagulant is dosed into the feed water-this helps to speed up clumping and settling. Typically, chemical is dosed to the DAF based on flow rate, but dosing based on flow ignores one major factor-the solids concentration! This leads to under and overdosing which could waste chemicals, increase hauling costs, and result in fines. Overcome this challenge by monitoring solids concentration in real-time and adjusting chemical feed based on the needs of the system.Watch Now
Dr. Gooddata, therefore, recommends that we largely abandon the term bias. Instead, we will use the terms systematic error and systematic uncertainty. Systematic error is the actual error that exists between a measurement and the true value with zero random errors. Systematic uncertainty is taken to mean the estimate of the systematic errors limits that we could expect with some confidence.Click Here
