formulations result in high wet strength products with excellent
sealing characteristics in the filter press, coupled with
extended sheet life. We have optimized product range to give
maximum clarity, stability and product life coupled with high
flow rates and high retention. As a result of special manufacturing
techniques, fiber release from sheet edges and the outlet
side of the filter sheet is prevented.
filter sheets are made from pure specially selected celluloses,
diatomaceous earths, perlites and resin systems. These raw
materials are chosen following extensive test work. In this
way we ensure their compatibility with our customers' products,
particularly beverages and most food products.
filter sheets are consistently checked during manufacture
on the production line and in the laboratory to ensure that
all specifications are met. Our systems are regularly audited
and enhanced thereby ensuring the consistent reliability of
our products. Most importantly, we use proven packaging methods
and materials, together with carefully chosen distribution
systems to ensure that all our products arrive at our customers'
premises in excellent condition.
Carlson started to
manufacture depth filter sheets over 50 years ago, the world
of liquids filtration has introduced many new, innovative
products and separation techniques. However, with the twin
virtues of depth filtration and electrokinetic adsorption,
the use of depth filter sheets in the filtration of liquids
to fine clarification and sterile levels, still remains a
most economic and cost effective way of achieving such objectives.
Efficiency & Dirt Holding Capacity
filter media is an excellent pre-filter and final filter for
countless applications where removal of contaminants such
as fine colloidal hazes, toxins, pyrogens, viruses and bacteria
is needed. Elimination of such contaminants is often not achieved
with absolute micron rated filters and so Carlson
media will both protect absolute rated membranes from premature
blockage, and also remove materials which might pass through
them. With their high voids volume, tortuous filtration path
and adsorbency characteristics, not only are particles smaller
than the so-called pore size retained, but the dirt holding
capacity is very high compared with many surface filters.
depth filter media is available in sheet form to fit virtually
any type of filter press. It is also utilized in lenticular
cartridge form to give the many benefits of depth filtration
within a totally enclosed cartridge system.
depth filter media is compatible with a wide range of organic
and inorganic liquids, often withstanding solvents to which
most polymeric filter media have limited resistance. This
property, coupled with a relatively high maximum temperature
for continuous use in service, gives Carlson
media an outstanding edge over many alternative methods of
of the components which make up Carlson
filter media are a renewable resource and great care is taken
to use materials of a non-hazardous nature. Whenever possible
materials which have incurred minimum energy input in their
production are utilized. We are determined to achieve the
best possible life cycle analysis for our products.
