Most HOB filters put the water into the aquarium in a smooth flowing downward sheet. This gives poor aeration. Most of the bottom to top flow hang-on-back filters use a curved lip on their outlet which puts the water out parallel to the surface of the aquarium. These can do decent aeration. Making a HOB a Fluidized Bed

All peat filters tested consistently remove greater than 90% of fecal coliform bacteria and many remove greater than 99%. The Puraflo 1-pass filters seem generally capable of a 1-log reduction in bacterial numbers. The two Brooks peat beds installed by this department show an average 4-log reduction in bacterial numbers.

The pellets of bad quality peat moss can be as hard as rocks and difficult to soak and use. Peat moss helps to soften the water but it cannot be used solo to convert hard water into soft water. For that, you need a RO/DI water system. Conclusion. Placing the peat moss in a bag and inside the filter is a good way to soften water and reduce the pH.
Construction for a 4′ × 8′ × 12″ raised bed with twice the growing space can cost anywhere from $50 for a frame and soil to $515. Tables 1 and 2 list the common frame materials used to construct a raised bed, the quantity of materials needed, and the average costs associated with building four different-size beds. Table 1.

The Puraflo peat fiber biofilter is an advanced secondary treatment system that purifies septic tank effluent to an extremely high degree before final dispersal. A typical Puraflo peat fiberbiofilter system consistsof: Septic tank with a commercially-rated effluent filter, with 1/32" filtration, connected to the tank outlet pipe
the bed of a filter medium. The medium is typically sand, but it can consist of soil, gravel, peat, compost or a combination of these materials. The filter bed removes small sediments and other pollutants from the stormwater. Finally, treated stormwater exits the sediment filter system via an outflow mechanism. The

Surface sand filters will not provide treatment during the winter. Underground filers are not effective in winter unless the filter bed is placed below the frost line. Peat and compost media are ineffective during the winter in cold climates. These filters retain water and can freeze solid, and thus become impervious.

Effluent flows from the septic tank to a pump chamber. It is then pumped to the sand filter. The sand filter is often PVC-lined or a concrete box filled with a sand material. Effluent is pumped under low pressure through the pipes at the top of the filter. The effluent leaves the pipes and is treated as it filters through the sand.
A pilot plant using column bed-filters of sand as a pre-filter, in combination with granulated activated carbon, Sphagnum peat or Pinus sylvestris bark, was used to investigate the removal of non-particulate OPs from urban stormwater. Samples from the filter effluents were collected weekly; during or after rain events; and during stress tests ...
