Cellulose
When it comes to filtering plating solutions and chemicals, Dicacel cellulose filter aids are the ultimate game-changer. Dicacel cellulose is the go-to choice for recovering catalysts and rare metals through filtration.
Applications of Cellulose
Dicacel cellulose filter aids are widely used in filtering plating solutions and chemicals where soluble silica is undesirable. The purity and combustibility of Dicacel offers a distinct advantage in recovering catalysts by filtration. The same advantage holds in metallurgical filtration for recovering rare metals. Dicacel cellulose filter aids are also extensively used for filtration of steam condensate from boiler operations.
How Cellulose Works as a Filter Aid
Cellulose acts as a precoat on the filter septum, creating a paper-like layer on the filter screen or cloth. By bonding together, the cellulose fibers form a rigid medium that easily bridges even the coarser septum openings. This means it builds up a precoat in no time, saving you valuable time and effort!
Dicalite perlite and diatomite filter aids may be applied over the first Dicacel precoat or mixed directly with diatomite.
Cellulose filters are made from thoroughly purified pulp, ensuring top-notch filtration characteristics in a wide range of grades. What makes them truly impressive is that they are essentially pure cellulose, which means they are practically ashless and non-abrasive. From pharmaceuticals to food processing, cellulose filter aids are the unsung heroes that help us achieve cleaner, purer results.
