* A thorough introduction to the design of gas-liquid fermenters and bioreactors Readers will also benefit from the inclusion of: Step-by-step processes are included throughout the book to assist engineers, chemists, and other scientists in the design, construction, installation, and maintenance of these systems. The accomplished author has created a practical and hands-on tool that discusses the subject of agitation systems from first principles all the way to implementation in the real world. The book covers agitator fundamentals, impeller systems, optimum power and air flow at peak mass transfer calculations, optimizing operation for minimum energy per batch, heat transfer surfaces and calculations, shaft seal considerations, mounting methods, mechanical design, and vendor evaluation.

If compared to an electrically powered washer it will be much more work, so if that is an alternative, there will need to be a strong motivation for the pedal powered washer to be used.AGITATOR DESIGN FOR GAS-LIQUID FERMENTERS AND BIOREACTORSĮxplore the basic principles and concepts of the design of agitation systems for fermenters and bioreactorsĪgitator Design for Gas-Liquid Fermenters and Bioreactors delivers a concise treatment and explanation of how to design mechanically sound agitation systems that will perform the agitation process function efficiently and economically. A pedal powered washer, if designed well, could potentially reduce effort and time needed compared to hand washing. Pedal powered washing machines Įase of use is obviously key. It's hard to imagine how to find another way of loading, unless the tub can be raised somehow (which adds complexity and may or may not be cheaper than the front loading design).
How can a cheaper washing machine be made that rotates on the horizontal access? Note that "front loading" is not the factor that makes it efficient - this is just the most obvious way of doing it. The downside is cost - why is this? (Needing the door to be more carefully sealed, i.e. Less water is used as the clothes are picked up and repeatedly passed through the small amount of water, rather than having to be all covered in water. Rotating the clothes on a horizontal axis (as in a front loading washing machine) is more efficient in water, detergent, and energy than on a vertical axis (conventional top loading washing machine). 
breeding mosquitos if the storage isn't perfectly sealed and maintained). It is hard to fully implement the countercurrent approach without storage for the different stages of used water, which may or may not be efficient and practical, depending on cost of storage, availability of water, nature of water disposal, and possible side-effects (e.g.
Using the countercurrent principle for rinsing, and using multiple stages with minimal amounts of water rather than one big rinse or having a spin-spray cycle (possibly less efficient). #Agitator design principles full
Washing full loads of laundry at a time instead of several small loads. Updating to a new energy star certified clothes washers, (Accessed: ).’’ uses 10 gallons less of water per full load and will also save money on the electric bill. 
Minimizing use of water in each stage, especially where detergent is used. Leaving the clothes to soak for a long time period, both in the washing stage (to loosen and dissolve dirt and oils) and in the rinsing stage (to remove adsorbed detergents. Principles of washing machine and cycle design Allowing time to soak and dissolve is one of the most important tools in effective and low-impact cleaning, as it reduces the impact of the other components. Using more of one component can help reduce the amount used of the others. Physical motion (scrubbing or agitation). This is usually a matter of managing the process so that there is maximum time for dirt, grease etc to dissolve, and has no environmental cost. This can greatly increase cleaning effectiveness, but causes carbon emissions, unless using solar hot water, or water heated with renewable energy. The choice of detergent is also important. Using less water achieves a greater concentration of detergent and thus less impact. The environmental impact depends on quantity and also how it is reused or disposed of. More of any of these will help to clean more effectively: General principles of cleaning Tap for more
