Long Beach, California was home to two exciting filtration related events at the start of 2017. The AWWA’s Membrane Technology Conference & Exhibition was an exciting gathering space for engineers, operators, and OEM’s working at the forefront of membrane applications. The Forsta booth provided an excellent meeting ground for the important discussion of reliable membrane prefiltration. Themes of conversations with Forsta at AMTA this year included; filtration at low pressures (15-20psi), filtration efficiency with organic material, variability in filter orientation, material selection and more.
Long Beach was also the host city this year for the 4th Annual Ballast Water Management Summit. At the summit this year, Forsta Director of Sales, Polly Stenberg presented to a group of key regulators, ship owners and operators, shipbuilders, engineers, water treatment specialists, marine equipment suppliers etc. on the subject of corrosion resistance in automatic screen filtration. The presentation demonstrated how Forsta has utilized Fiberglass Reinforced Plastic (FRP) and high grade stainless alloys to minimize corrosion resistance in saline lake beds, shipboard reverse osmosis desalination, plant desalination and produced water applications. The presentation generated an enormous interest for the inclusion of such techniques in the production and certification of Ballast Water Management Systems for compliance with new IMO regulation and USCG standards effective September, 2017.
The American Water Works Association’s Annual Conference & Exhibition is always a great time to connect with engineers, operators and OEM’s in the water industry. This year’s theme had an emphasis on uniting the world of water, including drinking, wastewater, stormwater and reuse.
Forsta had a great time this year, and had an opportunity to discuss the ongoing success in operation of equipment throughout sectors. A great feature each year at the show is the chance to give hands-on demos. There is no substitute for seeing Forsta’s robust equipment construction firsthand, and being able to get a sense of the streamlined integration of internal components.
It was especially exciting to be invited to participate in an interview with Water Online on the show floor. The interview provided a platform to discuss the Fiberglass Reinforced Plastic (FRP) Series of self-cleaning filters. Listen to the interview (below) to learn more about the how the corrosion-resistant series is being utilized in high-chloride filtration applications such as desalination and seawater cooling.
In addition to all the buzz around the FRP Series of self-cleaning filters, there were many discussions about other applications such as surface water filtration, filtration of non-potable water for land application, tertiary wastewater filtration, UF prefiltration and more.
Across the board, Forsta’s presence in the industry continues to be fortified by the relationships formed at ACE. In an age of internet an email, the Industry Trade Show gives us a rare opportunity to connect in person. We look forward to seeing everyone again next year!

Custom Fabricated Seawater Filters for Desalination Plant
Manifold, Piping, and Electronic Panel
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
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.
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
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
