“The Bollfilters have been brilliant, significantly reducing downtime and maintenance”

In 2011 Bollfilter UK supplied 3 x BOLLFILTER Automatic Type 6.18.2 Heavy Duty Filters to screen the raw seawater for various applications on site. The Bollfilter auto filters were fitted in place of duplex strainers supplied when the plant was built, as they required too much maintenance.

In 2014 Bollfilter UK were contacted again by Marchwood’s Mechanical Engineer to discuss replacing some existing auto filters from another manufacturer that were not up to the job and difficult to maintain. The application was the Electrochlorination Plant pre-filtration, a vital part of the water treatment system that needed the reliability of the Bollfilter design as proven on the seawater intake system.

Two BOLLFILTER Automatic type 6.18 DN100 of fabricated carbon steel with 3mm internal rubber lining and 316Ti stainless steel filter internals were supplied. The filter elements selected for this application were the special design – longitudinal round profile – (LRP) that have proved to be able to deal with seaweed, shells and marine crustaceans. Used as duty/standby or duty/duty if required, each filter is sized to treat 50 m3/h of seawater at 3.5 bar, filtering down to 300 micron.
