Water Desalination Report Thumbnail Forsta’s SWRO pretreatment filters which became operational in August of 2016 made news in the December 5 issue of the Water Desalination Report.

The 180 Fiberglass Reinforced Plastic (FRP) Series filters offer a perfect solution for corrosion resistance in brackish, brine and seawater filtration applications. All wetted components of the FRP Series self-cleaning filters are constructed from seawater- resistant plastic or other high alloy materials.

Forsta’s FRP Series self-cleaning water filters are available with an on-line, or in-line flange configuration to allow for simple installation, and easy integration with any pipeline in a seawater filtration process.

A two-stage screening distinguishes the FRP Series filters. A coarse screen is responsible for straining out large debris from the water source, and the fine screen purifies water to the designated micron rating.

Automatic Seawater Filters: Shipboard Reverse Osmosis Desalination

Forsta Filters has recently collaborated with BluMetric Environmental Inc. to provide custom automatic self-cleaning water filters for shipboard reverse osmosis desalination (SROD). The M2-90 U-Stamped ASME model filters for BluMetric are custom fabricated from Duplex Stainless Steel, made to withstand corrosive seawater environments. According to a recent news brief in Canada’s Martime Engineering Journal, the new automatic self-cleaning filters utilized in the Mk IV shipboard reverse osmosis desalination (SROD) system in HMCS Halifax (FFH-330), outperform conventional solid-liquid separation technologies in many aspects, including reduced operating costs and footprint.

According to BluMetric’s Managing Director of Military Systems, James Thomas, the level of pre-filtration on the new Mk IV SROD allows for continuous operation in littoral waters without any decrease in system performance or increase in operating costs or maintenance. Read the full article here:

 “Worldwide, some 700 million people don’t have access to enough clean water. In 10 years the number is expected to explode to 1.8 billion. In many places, squeezing fresh water from the ocean might be the only viable way to increase the supply.”

FRP Self-Cleaning Filter Seawater Skid

Application: Seawater Filtration at Reverse Osmosis Desalination Plant Flow Rate: 2100gpm Operating Pressure: 29-34psi Filter Model: Custom Skid Mounted Units 2x E10-LP180-FRP 1-on, 1-Standby Materials: Fiberglass Reinforced Plastic Housing with Super Duplex Screen, Wetted Components from Seawater Compatible Polymers and High Grade Alloys Screen Area: 12.25 sq ft per filter Degree of Filtration: 800 micron Control Panel: EC-2-LP-110-NEMA4-SW

 

  The 180 Fiberglass Reinforced Plastic (FRP) Series filters offer an ideal solution for corrosion resistance in brackish, brine and seawater filtration applications. All wetted components of the FRP Series self-cleaning filters are constructed from seawater- resistant plastic or other high alloy materials.


        A3-180FRP with 25 micron screen for sea water filtration

   Forsta Filters was asked to provide a solution for RO pre-filtration for sea water with high chloride content and high water temperature.

   With the FRP filter line, Forsta’s applications engineers were able to specify a quick solution that would hold up very well in these harsh environments, where other filters have failed.

   The customer’s idea was to install a self-cleaning water filter to replace the expensive and labor intensive cartridge filters. Forsta automatic backwash filter model A3-180FRP filter is flowing 80-100gpm through 25 micron screen. The filter uses less than 5 gallons of water per 12 second backwash, without disrupting the main flow. This solution saves the customer from spending time and money continuously replacing cartridges.

Filter Characteristics:

  • Flow Rate: 15 – 4,500 gpm
  • Flush cycle duration: 6 – 20 seconds
  • Flush valve size: single 1″ or a single 2″
  • Screen opening: 5µ – 4000µ
  • Temperature: 150ºF
  • Flush Volume: 4 – 50 gallons per backwash
  • Working pressure: 35 – 150 psi
180 FRP Series Filter

Forsta Filters’ exciting new FRP Series offers an ideal solution for corrosion resistance in brackish, brine and seawater filtration applications. All wetted components of the FRP Series self-cleaning filters are constructed from seawater-resistant plastic and other high alloy materials, making it the only one of its kind. The FRP Series filters can withstand pressures up to 150 psi and feature all the same great benefits of Forsta Filters’ stainless steel self-cleaning water filters.

Forsta’s FRP Series self-cleaning water filters are available with an on-line, or in-line flange configuration to accommodate simple installation, and easily integrate with any pipeline. A two-stage screening process distinguishes the FRP Series filters. A coarse screen is responsible for straining out large debris from the water source, and the fine screen purifies water to the designated micron rating. As with all Forsta self-cleaning filters, the FRP filter’s short backwash cycle never interrupts the main system flow.

Filter Characteristics:

• Flow Rate: 15-20,000 gpm
• Flush cycle duration: 6 – 12 seconds
• Flush valve size: single 1” or a single 2”
• Screen opening: 5μ – 4000μ
• Temperature: 210ºF
• Flush Volume: 2- 50 gallons per backwash
• Working pressure: 35- 150 psi
