Lenticular Filters

Incorporation of depth filter sheets in Lenticular module format means that Carlson's customers can enjoy the advantages of efficient, economical filter media in a robust, stable, non-compressible module. Modules and housings are available in both 12inch and 16inch diameter. Carlson incorporates all of its media grades in this format.

Carlson has incorporated a number of important design features in the new CARLENT module range. An interlocking disc design improves lateral strength and rigidity, whilst ensuring that only polypropylene to polypropylene contact throughout the internal core of the module. This alleviates any compressibility problems inherent in competitor's designs. This polypropylene centre core also protects against fibre release into the filtered product.

All standard Carlson modules incorporate a heavy duty non-woven polyester scrim which gives improved resistance to back pressure shock and a much improved back washing capability, in addition to providing an appreciable degree of pre-filtration prior to the depth filter medium.

Pre-compression during manufacture to precise dimensions eliminates the need for re-tightening down procedures. Optimum performance is achieved without reliance on operational procedure.

Advanced design of the FDA quality polypropylene separator discs and sealing rings promotes more even liquid flow within each cell. This in turn tends to reduce the pressure drop across the module, leading to longer module life, shorter filtration cycles and more consistent filtrate quality.

Lenticular housings

These are available in 12" and 16" diameter in either single or multi module version, up to 4 high, to suit small scale laboratory or pilot plant production to large scale continuous production. These can be stand alone or skid mounted.

Lenticular module lifting device

In 16" diameter format the weight of a used module can be unsuitable for manual lifting. This is especially true when multiple housings, with 3 to 4 high modules in each, have to be changed out. Since a suitable hoist is required to remove the dome cover Carlson has developed a lenticular lifting device to utilise this hoist. The lifting device can remove the complete set of spent modules from a housing in one simple and safe lift. The lifting device comes in sizes to accommodate 2, 3 or 4 modules high. The lifting device simply clamps the lower module, lifts the complete stack of modules and these spent modules can then be discharged into a suitable disposal unit with a pull of the discharge handle.
