Among the commonly used filter aids, diatomaceous earth is especially versatile and efficient. These fossilized skeletons of diatoms (single-celled algae) also known as kieselguhr offer benefits such as chemical inertness, a large surface area of up to 20 m² per gram and highest possible purity. The most important manufacturer of diatomaceous earth filter aids with the largest and purest deposits of diatomaceous earth in the world is the Celite Corp. in Lompoc, California. Other Celite deposits are located in the US state of Washington as well as in France, Spain, Mexico, Chile and China. Celite diatomaceous earth filter aids are prepared from especially high-grade diatomaceous earth deposits.

Celite Cynergy® 200HS. Improved utilisation of the solids space. Improved filter life. Reduced specific filter aid use. Fewer filter cycles. Improved pressure curves. Reduced amount of filter sludge. Reduced recycling costs. By combining two tasks in one product and a higher permeability (Darcy) compared to usually very fine silica xerogel, Celite Cynergy® 200HS increases the efficiency of your filtration and reduces costs. Following the successful launch of Celite Cynergy® 200 in 2010, which has the same adsorptive properties as a silica hydrogel, we are now pleased to present the new Celite Cynergy® 200HS (HS = High Stability) variant. The adsorptive effect of Celite Cynergy® 200HS is comparable to that of a silica xerogel..

Stabilizers are used to remove turbidity that may result from proteins or yeasts and other suspended particles from the beer. In this way beer is stabilized both in microbiological and in chemical/physical terms.

The LEHVOSS Compounds division supports designers, design engineers and component manufacturers in defining the most suitable plastic for their component and thus in developing more powerful components with lower system costs. Customers benefit from our well-founded knowledge of materials and applications, the independent selection of raw materials and the decades of experience of the LEHVOSS engineers. The basis for this was laid by the LEHVOSS Group back in the 1910s as the world market leader for casein.
