Environmentally friendly filtration of cooling tower loop cuts waste and disposal costs

[Ask Filter Man]

A manufacturer of plastic personal grooming products was recycling
mold-cooling water through a cooling tower. Unfortunately, the cooling
water was picking up airborne particulate in the process, which caused
frequent blowdowns, required maintenance, and created downtime on the
molding machines.

Traditionally, engineers have opted for disposable media filters
because of their lower initial cost. While initial cost may be lower
for small batch operations, the same is not necessarily true for
continuous operations.

That is because you would need a completely redundant filtration
system, including piping, valves, supports, and service connections -
not an insignificant expense by any means - to maintain production.

To remove this particulate, the company installed a Ronningen-Petter
(RPA Process Technologies) self-cleaning filter. With this type of
filter system, the media is cleaned and regenerated while the unit
remains on-line.

This means a simple single-piping arrangement, minimal valving, and
fewer connections - for a lower total system cost and reduced waste.
Since then, they've eliminated this costly downtime and reduced their
waste.

What's more, controlling suspended solids by filtration rather than
blowdown substantially reduces water use.

Moreover, because the filter cleans itself only when necessary,
treatment chemicals and waste disposal costs are minimized.
