TYPICAL APPLICATIONS

DF5
DF10
DF40

  Alkaline Chemicals : The filtration of alkalis when other principal filter aids (diatomite and perlite) cannot be used because of their silica solubility. Thpical examples of such filtrations are strong alkaline solutions such as 50% sodium hydroxide, sodium ilicate, preparation of alumina and plating solutions.

DF200

  Brine Filtration : In diaphragm and mercury cell chlorine caustic plants, brine is filtered with cellulose on pressure filters.

  Condensate : DICAFLOCK will dffectively remove suspended metallic partiles and absorb traces of oil contained in boiler condensate water, resulting in a very pure, almost dolid-free filtrate. Other silica based filter aids have a slight silica solubility, making them objectionable for this use.

DF40

  Emulsions : DICAFLOCK will break emulsions of oil in water or the reverse and in cases where only traces of oil are emulsified in water, will absorb the oil very effectively, resuting in long cycles and high flowrates.

  Catalysts and Rare Earth Metals : Since DICAFLOCK is an almost ashless material, it is the preferred filteraid for the filtration of these materials, since they can be easily recovered from the fiber cake by combustion. This also applies to the filtration of some metallic ores, such as uranium, lead, titanium, tungsten, etc...

  Beer, Beverages, etc... : In these filtrations, DICAFLOCK is used as a precoat to avoid bleed-through of diatomite or perlite filter aids. A DICALOCK percoat permits very easy and rapid cleaning of the filters at the end of the filtration cycle, which will substantially reduce clean-up time.
