By using a filtration process similar to that used in water treatment plants, it is possible to remove the residual suspended solids, including the unsettled microorganisms. Removing the microorganisms also reduces the residual BODs. Conventional sand filters identical to those used in water treatment can be used, but they often clog quickly, thus requiring frequent backwashing.
To lengthen filter runs and reduce backwashing, it is desirable to have the larger filter grain sizes at the top of the filter. This arrangement allows some of the larger particles of biological floc to be trapped at the surface without plugging the filter. Multimedia filters accomplish this by using low-density coal for the large grain sizes, medium-density sand for intermediate sizes, and highdensity garnet for the smallest size filter grains. Thus, during backwashing, the greater density offsets the smaller diameter so that the coal remains on top, the sand remains in the middle, arid the garnet remains on the bottom.

What removes most of the suspend solids from the water in a 3000 gph rowpu?
A combination of physical processes such as sedimentation and filtration is commonly used in a 3000 gph Reverse Osmosis Water Purification Unit (ROWPU) to remove suspended solids from water. The ROWPU typically includes pre-treatment steps like coagulation and flocculation to help agglomerate the suspended solids for easier removal. Additionally, cartridges or filters can be used to trap suspended particles as water passes through them.
What step in the copy process removes residual toner from the OPC drum surface and recycles the toner?
The step in the copy process that removes residual toner from the OPC drum surface and recycles the toner is called the "cleaning" phase. During this phase, a cleaning blade or brush sweeps across the drum to remove any leftover toner after the image has been transferred to the paper. This residual toner is then collected and sent back to the toner cartridge for recycling, ensuring efficient use of materials.
