Activated carbon powder has been used in filter sheets for many years, primarily for colour removal from low grade sugar syrups and chlorine removal from water to be used in soft drinks production. The number of carbon sheet treatment applications has escalated, not only in their variety, but also because of their convenience.
Benefits • no need for use of loose activated carbon powder or granules
• no need for use of filters and filter aids to facilitate removal of activated carbon from the process fluid
• no messy filter cake
• less time consuming
• easier and cheaper disposal of spent filter materials
Always remember, as with all activated carbon treatment systems, the quality, grade of activated carbon and resonance time affects the adsorption capacity. The sheet life depends on the amount of colour / odour / off-taste / chlorine to be removed and the dwell time of the liquid within the sheet.
Bespoke grades of carbon can be varied to suit the customers requirements – although minimum order quantities may apply. Only the LWT versions can be used in lenticular cartridge (modules) construction.
All grades are available with protective backing paper, if required. Carbon treatment applications. These include de-colourisation of blood products, glucose solutions, antibiotics, solvents, sugar syrups, cosmetics, silicone oils, electroplating chemicals, alcoholic beverages; de-odourisation of fruit juices, beverages; de-chorination of water; off-tastes removal in food and beverages.

The Carlson XE range of products is comprised of a comprehensive series of high performance filter sheets designed to meet the needs of a range of specialist applications. All filter sheets within the XE range are formulated with several important
features in mind:
All XE filter sheets comprise of an advanced blend of selected and processed bleached cellulose fibres combined with non-hazardous filteraids and approved resins to produce filter media with superior filtration capabilities in conjunction with excellent wet and dry handling characteristics. All the raw materials used in the manufacture of XE products are carefully selected and monitored to ensure their compatibility with beverages and food products. All XE products are made to the same carefully controlled thickness specification so that the different grades can be used in the same filter press configuration and seal thickness. Edge leakage is reduced to a minimum because of the special XE filter sheet formulation and processing conditions.
XE filtration sheets are widely used in the filtration of products where they give outstanding clarity and stability combined with long sheet life and integrity.
Typical applications of the XE range include spirits, wines, beers and lagers where long life, sterility, stability and clarity are essential. Similarly, XE products have found wide acceptance in the filtration of syrups for soft drinks, gelatines and cosmetics, plus a diverse spread of chemical and pharmaceutical intermediates and final products. Instructions for correct use: When inserting into the filter press handle the filter sheets with care to eliminate distortion or abrasion. Never use a damaged filter sheet.
Insertion of depth filter sheets: To ensure correct use place the smooth side of the filter sheet against the filtrate plate (i.e. downstream). The rough side of the filter sheet faces the liquid to be filtered (i.e. upstream)
Filter preparation: Prior to the first filtration it is recommended where' possible to pre-rinse the closed filter with approximately 50 litres of water per m2 at 1.25 times the flow rate. During pre-rinsing check for leakage, re-tighten to eliminate if necessary.
Sterilisation: Carlson range of XE filter sheets may be sterilised with saturated steam or hot water. The pressed filter pack has to be loosened slightly to ensure that the steam entirely sterilises the system. Final pressure should only be applied to the filter package once the entire filter has cooled down.
Sterilisation with steam: Steam quality: Steam has to be free of foreign particles and impurities.
Temperature: max 134ºc (saturated steam)
Duration: 20 minutes Sterlisation with hot water Water quality: The water should be softened and be free of impurities
Temperature: 80-85ºc
Duration: 20 minutes
Sheet flushing: The Carlson range of XE filter sheets can be forward and back washed using softened water to extend the life and reduce the costs of filtration. This is however, very much dependent upon the application and filtration conditions.
Regeneration procedure:
Cold rinsing: in direction of filtration for approx 5-10 minutes
Temperature: 15ºc - 20ºc
Hot rinsing: forward or reverse direction of filtration for approx 10 minutes
Temperature: 60ºc - 80ºc Safety and disposal Used under the correct conditions Carlson range of XE filter sheets have no known negative effects and can be disposed of through normal route, observing local and official regulations. Consult MSDS for further information
