What is Dicalite?

Diatomaceous earth’s high functionality is due to the exoskeletons of prehistoric animals. Sound bizarre? Diatoms are tiny, silicon-based animals with outer skeletons of varying intricate designs. These tough outer coverings are all that remain of prehistoric sea life. When these remains gather in high quantities, they can be mined as diatomaceous earth. Why earth? Because, like diatoms, the earth is made of a large amount of silica. The removal of diatoms from the ground solidified the name of this extremely useful product. Bell Chem proudly stocks dicalite products that range in abrasiveness depending on the size and structure of the diatoms. Below are a few uses of water treatment chemicals supplier Bell Chem’s variety of dicalite diatomaceous earth inventory.

Diatomaceous earth heated to 1500℉ clusters the fine diatom exoskeletons together. This creates products known as “calcined” and offers a greater range of filtration permeabilities. When diatomaceous earth is heated above 1500℉, the calcified exoskeletons clump together, which transforms the normally fine grains into more varied sizes. Flux calcination changes the filtration even further by increasing the calcification agglomeration rate, thus opening the range of permeabilities. The finer the granulation, the slower the filtration rate.

  • As an absorbent, dicalite is ideal for cleaning oil spills or, on a much smaller scale, for removing oil from the skin as an ingredient in cosmetics. Diatomaceous earth is more absorbent than any other commonly used material, with the ability to hold 145% of its weight in oil.

  • As a natural abrasive, dicalite can be used in a range of products from toothpaste to metal polishes. Composed of silica, it has no negative side effects on the environment or the human body. Superfine granulated dicalite is ideal for facial scrubs, while a coarser grain works to scrub countertops and dinnerware.

  • Anyone with animals will find dicalite a fantastic, all-purpose product. Sprinkle it in small animal pens as a natural insecticide: the insects ingest the pointed shells, which tears apart their digestive systems. Use it in feed to stop clumping and remove moisture, which gives feed a longer shelf life. 

Dicalite is a pure, natural product that contains no chemicals and is safe to use. Bell Chem carries Dicalite UF and Speed Flow for fine filtration, Dicalite 341 Flux-Calcined and Speedplus for medium filtration, and Dicalite 2500 Flux-Calcined and Dicalite 4200 Flux-Calcined for coarse filtration. Bell Chem is a water treatment chemical supplier based in Longwood, FL (just north of Orlando) with hundreds of products stocked in their 50,000+ square-foot warehouse. You can expect the highest quality products, expedited shipping options for maximum efficiency, and unrivaled personalized customer service.

What We Provide: Technical Grade & Water Treatment

Water comes out of the faucet clean and clear, just like it looks in a stream. However, in order to be safe for consumption, it must be treated by filtration and chemical processes. Below are the water treatment chemicals that Bell Chem offers.

Algaecides, Biocides, and Disinfectants
Though the chemical formulae may differ depending on their use, algaecides, biocides, and disinfectants all kill dangerous microorganisms. Copper sulfate and sodium bromide crystals successfully destroy algae, while Bell Chem’s inventory of chlorinated detergents excel as biocide agents.

Antifoams
Chemical reactions from water purification cause gas bubbles as a by-product. As liquid films coat the bubbles, larger and larger masses occur, effectively blocking production. Silicone in an oil dispersant breaks apart that foam. Bell Chem’s stock of 19 varieties of silica are available in powder form or as an emulsion.

Coagulants
Within a water treatment system, aluminum is a choice coagulant because of its ability to snap up loose ions. Depending on usage, aluminum chloride, aluminum oxide, or aluminum sulfate may be necessary.

Corrosion Inhibitors
Corrosion can cause failure of machinery, deposition in water, and overall loss of time and money. Inhibitors coat metal surfaces to protect clean metal or disable the properties of corroded metals. Calcium hypochlorite scale inhibitor and cyclohexylamine work in two distinct manners to inhibit corrosion.

Flocculants
Ionized polymer flocculants act to coagulate suspended solids in water. The sheer weight of the particles is then great enough to cause them to sink, or their size leads them to be caught in filters. Alum and aluminum sulfate are both effective flocculants.

Neutralizing Agents and pH Adjusters
Controlling the pH balance is imperative for a clean running system. Sodium hydroxide, sulfuric acid, hydrated lime, calcium carbonate, and hydrochloric acid are all prime examples of neutralizers. Hydrogen chloride adjusts pH levels to prevent lead contamination and corrosion.

Oxidizers
To quell biological and chemical oxygen demand, oxidizers convert available oxygen to carbon dioxide and water. Bell Chem’s two strengths of hydrogen peroxide work well as oxidizers, corrosion controllers, and odor deterrents.

Oxygen Scavengers
Working similarly to oxidizers, scavengers prevent oxygen from interrupting oxidation reactions. While non-volatile sodium sulfite and volatile methyl ethyl ketone are both oxygen scavengers, their reactions differ significantly.

Resin Cleaners
The chemical reactions causing ion exchange have potential problematic by-products that cause resins to become contaminated. Bell Chem stocks citric acid, sodium chloride, and potassium chloride to remedy this situation.

Scale Inhibitors
Temperature increases cause many soluble solids to float to the surface of the water. Bell Chem’s phosphoric acid works as a great scale inhibitor.
