Again, thank you for purchasing your high rate sand filter from Paragon Aquatics.
1.0 Basic Principles of Operation
Your high rate sand filter is designed to operate for years with a minimum amount of
maintenance when installed, operated and maintained in accordance with these instructions.
1.1 Filtration - How Your Filter Works
The basic principals of filter operation are as follows:
Dirty water enters the filter tank by being pumped under pressure through the influent
pipe and is distributed across the top of the inner tank chamber through diffusers. The water is
then forced downward through the sand filter bed. Dirt and debris is collected in the sand bed
allowing clean water to pass through. The clean water then passes through the collection laterals
and exits the filter through the effluent piping and is returned to the pool.
