Declining‐Rate Filters: Regulatory Aspects and Operating Results
Although the current design trend is to use constant‐rate filters, significant operating data now show that use of declining‐rate filters includes such benefits as economy and ease of operation. A survey of state regulations showed that no specific requirements exist for the design and operation of declining‐rate filters and that the regulations often do not distinguish between the two types of filters.
