STS SERIES MEDIA FILTERS
Installation, Operation, & Maintenance
Manual
I.
INTRODUCTION
The LAKOS STS Series Media Filters are specifically designed for use in full-
stream, side-stream, and basin sweeping (SWP) applications. For side-stream, we
recommend the industry standard filtration rate range of 10%-20% based on the full-
stream flow of the system. The standard STS Series Sand Filters can be filled with
media for either 10 micron filtration @ 95% removal efficiency (standard), or 5
micron filtration @ 90% removal efficiency (optional). Please refer to section X for
“How it Works” STS system diagram.
The LAKOS STS Series Media Filters can be installed for either full-stream
operation or side-stream operation (most common). Side-stream installations
should be applied by tapping into a mainstream line after the pump (see drawing
STS-0001), or by tapping directly to a basin or remote sump to achieve a given
turnover rate.
Please note that all standard STS system pumps require flooded
suction for proper operation!
Please contact the factory if you have a installation
that will require the pump to lift water!
LAKOS does not recommend using the standard STS Series Media Filters for
basin/remote sump sweeping applications.
The proper use of this technique
requires a specific sweeping design using Hydroboosters and the proper
flow/pressure to ensure maximum performance. LAKOS does offer a special
system (SWP) for sweeping applications. These systems come with higher head
pumps to meet the specific pressure requirements needed for basin sweeping.
Please contact the factory to see if the STS/SWP Media Filter can be used for your
application.
The maximum operating pressures for the LAKOS STS Series Sand Filters are as
follows;
- STS-15-025 thru STS-36-165 models: 100 psi (6.9 bar)
- STS-48-310 models: 80 psi (5.5 bar)
