Additional research Since the release of the initial 1989 study, titled A study of interior landscape plants for indoor air pollution abatement: An Interim Report, further research has been done including a 1993 paper and 1996 book by B C Wolverton, the primary researcher on the original NASA study, that listed additional plants and focused on the removal of specific chemicalsOptimizing Your Plant’s Filter Performance continued from page 37 service immediately and one washed and left to sit for four hours before being put into service The turbidity characteristically increased at the beginning of the filter runs However, the filters that had a fourhour delay did not increase in turbidity as much as the others, andOptimizing Your Plant’s Filter Performance

Drinking Water Filtration Using Granular Activated Carbon

In plants which utilize a surface wash, it is common to backwash at a low rate to allow the surface wash to scrub the top of the filter The backwash rate is then increased to 1517 gpm/ft2 for 1015 minutes to wash the filtered particles from the filter In deep bed filters and those in difficult filtration situations, an air scour is usedBy growing the plants beneath color filters, you can determine which color of light produces optimal growth Types Visible light is a form of electromagnetic radiation with wavelengths ranging from 400 to 750 nanometers, where a nanometer is onebillionth of a meterThe Effect of Color Filters in Photosynthesis | eHow

CEI Anthracite CEI Filtration

CEI Anthracite manufactures high quality, dry and low uniformity coefficient anthracite filter media CEI Anthracite’s <13 uniformity coefficient can provide many benefits in granular bed filters, including: Increased plant capacity by the use of higher filtration rates; Lower backwash rates in dual and trimedia filters; Better production efficiency due to longer filter cycles at higherFor example, filter carbon in a 10" X 54" filter has a performance limit of about 3 gallons per minute, but such filters are frequently used in residential applications with much higher flow rates There is no great harm in this since the undersized filter removes most of the chlorine most of the timeHow Backwashing Filters Work – Pure Water Products, LLC

Choosing the Proper Flow Rate for Your Aquarium

This is essential for filter feeders The following types of tanks do better with slower flow rates: Live plant tanks Decreasing surface agitation helps hold in the CO2 much needed by plants Most plants cannot tolerate being in the middle of the flow stream Small fish, baby fish, and betta tanks need a very slow flow rateSometimes water treatment plants do not have a means via flowmeter to determine backwash rates These rates need to have a velocity high enough to separate the media so trapped particles that work their way into the filter can be lifted and removed during a backwash Typically, the backwash rate should be a minimum of three times its filter rateExam Study Guide: Backwash Rate | Treatment Plant Operator
