Does the unit capture and retain nutrients and suspended solids and what are the efficiency removal rates?
Nutrients and suspended solids are captured by the RSF 4000 units, albeit at relatively low rates. This is mainly due to their attachment to the finer silts and sediments that are captured at much-higher rates. However, it must be understood that the RSF 4000, like all other GPT units, is a primary filtration device and that secondary treatment processes, such as sand filters, may also need to be considered if high efficiency removal of these constituents is required. Such secondary measures by themselves are usually not appropriate as they can block very quickly if the larger pollutants have not already been filtered from the flow by some form of primary filter.
