  • Mechanical Denitrification or Deep Sand bed? | REEF2REEF ...

    I've had my 90 gal. saltwater tank for 12 years and have always had at least a 4 in. deep sand bed in the DT. I recently upgraded to a 120 gal and plan on using my old 90 for a refugium/sump tank. In the beginning I had a few mushroom coals here and there but pretty much only fish, inverts, rock, and sand.

  • How To Solve Your Biggest Issues with Washing and… | McLanahan

    Among the simplest devices for washing sand and removing silts and clays is a Fine Material Screw Washer, often called a sand screw. It can be installed on the ground next to a wet vibrating screen. Via a simple flume or chute, a slurry flow of water and sand can be used to feed the sand screw.


  • P&Q University Lesson 9- Washing & Classifying : Pit & Quarry

    Washing and classifying of aggregate can be considered in two parts, depending on the size range of material. Coarse material: Generally above 3/8 in. (sometimes split at 1/4 in. or #4 mesh). In the washing process it usually is desired to remove foreign, objectionable material, including fine particles.



  • Continuous, Upflow, Granular Media Filter - Parkson

    Sand Cleaning The sand bed containing captured impurities is drawn downward into the center of the filter where the airlift pipe (F) is located. A small volume of compressed air is introduced at the bottom of the airlift, drawing the sand into the airlift pipe. The sand is scoured within the airlift pipe at an intensity of 100-150 SCFM/ft2. The


  • Learn How to Use a Deep Sand Bed in Your Tank

    Thus, a deep sand bed can perform both nitrification and denitrification, but it is very important that strong circulation of aquarium water, 10 to 20 times the entire volume of the tank per hour, over the surface of the bed be present for this filtration technique to work properly.

  • Sand Washing Machine Parameters and Models | LZZG

    What is a sand washer The sand washing machine is used to remove impurities such as dust, silt, and other unwanted particles from sand products. It can remove impurities covering the surface of sand and gravel, and destroy the water vapor layer of the coated sand to facilitate dehydration and play a role in efficient sand washing.


  • Davco™ Continuous Backwash Sand Filters - Evoqua

    In addition, the continuous backwash sand filter is easy to operate and allows for mechanical, chemical, and biological filtration processes. Features Features Options for concrete, stainless steel or fiberglass tanks Deep bed filtration, up to 120 inches Phosphorous removal to low levels Denitrification and nitrification options


  • DynaSand® Denite Filter - Denitrification Filters | Parkson ...

    Denitrification Filters DynaSand ® Denite provides a single-step solution to remove nitrates (NO3) and nitrites (NO2) in order to meet ultra-low effluent nutrient limits. The DynaSand filter achieves denitrification performance with less energy and in a smaller footprint than alternative conventional technologies.


  • Denitrification in a Moving Bed Upflow Sand Filter - JSTOR

    An alternative configuration for denitrification is the moving bed upflow sand filter. This design uses a simple airlift and washer system to clean the filtration media continuously, thus avoiding the need for a backwash control system and eliminating much of the piping associated with conventional rapid sand filters.


  • Denitrifying Deep Bed Filter (DDBF™) - Orthos Filters

    In the DDBF™, denitrifying organisms attach to the filter media.Supplemental carbon is augmented to the filter influent to drive the denitrification process. Wastewater flows around nitrogen gas bubbles that accumulate in the media and reduce the space between sand grains, which improves biomass contact and filtration efficiency.
