A range of compact, fully automatic, self-cleaning fibrous depth filtation systems designed to eliminate or reduce particulates in aqueous feedstreams, either prior to use in the process, or before discharge from the process.

Fibrotex enables a choice of water sources, including boreholes, rivers and canals to be utilised, minimising the consumption of costly mains water.

Fibrotex filters are based on a unique, yet proven technology and use advanced materials and construction techniques to provide effective, compact and reliable filtration solutions to the water quality problems of industry.

The Technology   (back to top)

Filtration – The FIBROTEX filter element comprises thousands of high performance synthetic fibres arranged in a bundle around a central core. During filtration, the fibre bundle is twisted and compressed, to form a tight helical matrix. The feedstream passes radially from the outside to the inside of the element, with particulates being captured within the fibrous matrix and held until the element reaches a pre-set loading.

Backwashing – When the filter element is fully loaded, an automatic backwash cycle is initiated. During backwashing, the element is first untwisted and stretched and is then ‘wrung out’ by an alternate twisting motion. A small ‘backwash’ flow of water is introduced during the backwash cycle, and this is drawn into the individual fibres and expelled, along with the dirt, as the fibres are alternatively stretched, squeezed and relaxed. A highly concentrated backwash stream leaves the system before the next filtration cycle commences.

Benefits

• Fine Filtration
• Enables use of lower cost water sources, such as boreholes, rivers and recycled waters from waste streams
• Improves longevity of downstream filters, reducing replacement costs by up to 80%
• Ensures compliance with discharge consents for waste water
• Protects downstream reverse osmosis plant, preventing damage to membranes and reducing maintenance costs
• Removes particulate from process streams
• Improves safety by removing harmful organisms, both from the supply and sand filter backwashings.
• Compact Plant
• Enables installation within existing plant room
• Minimal installation costs
• Complete containerised filtration system provides mobility
• Low Backwash
• Low volume requirement creates less effluent and uses less water
• Short backwash cycles minimise process disruption
• Self backwash capability requires no external backwash source
• Yarn Types Available
• Different yarn types to provide a range of removal ratings and chemical compatibility across the pH range.
• For fine duties, Fibrotex is available with high performance Nylon elements with removal efficiencies of 98% down to 2 micron
• For applications where the feed stream contains higher levels of suspended solids, a polyester (PBT) element can be used. It has removal efficiencies of 95% down to 5 microns and is made from a material which is almost inert to chemical attack.

Markets for Fibrotex   (back to top)

Municipal Market

After the management buyout in 1991, Kalsep UK quickly established Fibrotex as the leading fine filtration technology guaranteeing 2 log removal for cryptosporidium. Systems varying in size up to 80 mld were sold to most of the leading UK municipal PLCs. In addition to cryptosporidium removal, Fibrotex has been used for iron and manganese removal, borehole and river water filtration and as a polishing filter.

Fibrotex filtration systems have been designed to meet the changing needs of the municipal industry both in the UK and overseas. They are reliable, efficient and have been proven in applications throughout the world either as a standalone unit or in containerised systems. For remote, small population locations containerised systems have been frequently used.

Operating under the Institute of Chemical Engineers Green and Red Book, Kalsep UK has acted as main contractor and subcontractor on projects up to £7m in value. Kaslep UK has worked with many OEMs, consultants, main contractors and engineering houses to provide the right solutions for the customer.

In addition to the specialist design and fabrication, Kalsep UK can also provide a complete M&E turnkey installation. Once the plant is installed, Kalsep UK can provide a friendly and helpful after sales servicing package in line with specific customer requirements.
