Unicellular algae called diatoms, which form a siliceous test or frustule, are an ecolog-ically and biogeochemically important group of organisms in aquatic environments and are often preserved in lake or marine sediments. When diatoms accumulate in large numbers in sediments, the fossilized remains can form diatomite.
Imerys operates diatomite deposits and processing algae in the US, Mexico, Chile, Peru, France, Spain and China, including one of the planet's largest worked diatomite mines, and only marine deposits, in Lompoc, California. Imerys is the world leader in diatomite production. We carefully engineer our products to provide sustainable diatomite ...

Our Celite Fibra-Cel range are cellulose-based products ideal for rapid pre-coating in beer and wine filtration, especially when old or damaged screens are being used. The Celite Fibra-Cel range offers a stable cake formation and can protect the filter cake against unwanted pressure shocks. It also aids filter cake release during filter wash-offs.
Diatomite is used in many applications as the uniquely porous nature of each particle gives diatomite high surface area, low bulk density, high permeability, high water absorption, and low abrasion. Diatomite filter aids are used to prevent blinding of filter elements and are used to clarify liquids in brewing, water treatment, wine making ...
2022. The United States remained the leading global producer and consumer of diatomite. Filtration (including the cleansing of greases and oils and the purification of beer, liquors, water, and wine) continued to be the leading end use for diatomite. An important application for diatomite is the removal of microbial contaminants, such as bacteria,
Vintners use diatomaceous earth for wine filtration alone, or it's used as the second step in the filtering process.

The Maidenwell diatomite is composed dominantly of Melosira granulate diatoms with about 50% intact siliceous skeletons and the remainder broken skeletons. Total Silica generally exceeds 85% of dry sample weight. Notable amongst these properties are the high plant available Silica, high water holding content at saturation, low bulk density, low ...
Diatomite should not carry any odour or foreign taste to the wine. Put 2.5 g of diatomite in a litre of wine. Mix. Leave 24 hours. Compare the taste to wine not containing any diatomite. 3.2. Loss during drying. Put 5 g of diatomite in a capsule. Heat in an incubator to 103 ± 2°C. After two hours mass loss should not be more than 1%. 3.3.
The review tackles common diatomite, its characterization, modifications and its composites, heavy metal toxicity and its immobilization techniques using diatomite, …
Diatomite. A diatom is an organism that is a member of the phylum of algae called Bacillariophyta. There are about 60,000 species of these algae presently known. Experts estimate that there are more likely 600,000 to 6,000,000 species in total! Diatoms are single-celled (unicellular) organisms that live as individuals or in groups called colonies.
Diatomite is widely used as a filtering material in spirit-containing systems industry. In the presented paper, different types of treatment of diatomite from the Jradzor deposit, and …

How to use: The diatomite filter can filter 0.5-1.5 tons of wine by adding 0.5 kg of coarse soil and 0.5 kg of fine soil at a time, depending on the turbidity of the wine. Using 15 high-density filters, 15-layer purification, can remove particles below 1-0.1 microns, etc., with good clarification and filtration effects.
