Electromedia VIII - Seawater Filtration System

Sea water filtration requires costly and compatible materials that will not rust or corrode. The harsh environment requires effective and reliable performance. Filtronics Electromedia VIII provides an effective, economical solution to these issues by utilizing sea water resistant alloys and lined and coated carbon steel tanks. Coupled with our Envirowash backwash reclaim system, you will have a life long system with a reasonalble capital cost.

To ensure trouble free operation of seawater desalination systems, membrane manufacturers recommend pre-treatment for the removal of suspended solids to negligible levels for the preservation of the effectiveness and life span of a Reverse Osmosis (RO) installation. A proper selection of pre-treatment for feed water will improve affectivity and extend the life span of the system by preventing or minimizing biofouling, scaling and membrane plugging.

The close spacing of spiral wound membranes results in trapping of suspended solids inside the modules. This is exacerbated by the fact that, RO membranes bear a surface charge which may cause fine solids to be attracted to the membrane surface. Once fouling begins, cleaning of the membranes becomes very difficult and the system may not return to the original performance levels. Cleaning costs, system performance and standstill time are very significant in that situation and generally can be traced back to inadequate pre-filtration.

When sea water filtration is needed for pre-treatment to desalination or other applications, Filtronics will design a simple, proven and cost-effective treatment system based upon influent quality, economics and space management. Filtronics uses only ANSI/NSF Standard 60 and ANSI/NSF Standard 61 compliant media.

FILTRONICS ELECTROMEDIA VIII offers a unique and cost effective solution for the removal of suspended solids in sea water.

Our standard controls package uses a PLC and graphic display panel for automatic, unattended operation. Automatic filter controls include reset timers for filtration, backwash and purge. Backwash is initiated by time or differential pressure override. Controls are housed in a NEMA 4X or NEMA 12 enclosure.

• Flow range from 20 to 1500 gpm simplex systems. Multiple vessel systems up to 20,000 gpm or more.
• 60 psi pressure tank ASME code, stamped. (Higher ratings available.)
• Filter tanks are carbon steel, with lining on all wetted surfaces.
• Backwash flow controls, air release valves, automatic filter control valves.
• Standard interior fittings: PVC, and/or stainless steel.
• Each tank fitted with 12” X16” access hatches, 6” x 8” hand holes, or manways depending on filter size.
