This numerical technique for identifying fresh water and wastewater targets eliminates the tedious and time-consuming steps of graphical targeting approaches. Use it to complement the graphical techniques in the design and retrofit of water networks.
A linear equation has been derived to accurately calculate the flowrate of fluids in the laminar and turbulent regions, and to derive an equation for use in the transitional regions.

Size does matter - and bigger is not necessarily better when it comes to pollution control. It is more important to be the right size than the largest size.

Unlike time-consuming conventional methods, this approach to designing a dissolved air flotation (DAF) plant requires only the physical characteristics of the flocs — their size and density, flowrate and temperature.
This article presents the challenges that an engineer might encounter when designing or scaling up bioprocesses and offers practical solutions, including those cited in literature.

These tools and techniques can be used to make sense of soil or groundwater contamination - where it came from, who is responsible for it, and how to fairly allocate the costs to clean it up.

The challenges of vaccine development are not limited to identification of suitable antigens, adjuvants and delivery methods, but include regulatory, technical and manufacturing hurdles in translating a vaccine candidate to the clinic.

A compliance management system (CMS) helps companies meet regulatory reporting requirements, improve environmental performance, reduce environmental compliance costs, and increase organizational efficiency. Here's a run-down of what to look for when...
Using a phased engineering approach to guide R&D projects will improve efficiency and avoid costly experimental excursions.
