Celite Cynergy® 200HS By combining two tasks in one product and a very fine Silica xerogel higher permeability (Darcy) Celite Cynergy® 200HS increases the efficiency of your filtration and lowers the costs. Following the successful launch in 2010 of Celite Cynergy® 200, which offers the same adsorptive has properties similar to those of a silica hydrogel, we are pleased to present the new Celite Cynergy® 200HS (HS = High Stability). The adsorptive effect of Celite Cynergy® 200HS is comparable to that of silicic acid xerogels comparable. Celite Cynergy® offers: - Improved utilization of the cloud space - Improved filter service life - Reduced specific filter aid use - Fewer filter cycles - Improved print gradients - Reduced amount of filter sludge - Less exploitation costs

The most common filter aid, which meets all requirements, is diatomaceous earth, also known as diatomaceous earth. The IMERYS is the most important diatomaceous earth filter aid producer with the largest and purest diatomaceous earth deposit in the world in Lompoc, California. IMERYS also mines diatomaceous earth in the states of Washington and Nevada (USA), in France, Spain, Mexico, Chile and in two plants in China. Celite diatomaceous earth filter aids are made from particularly high-quality diatom deposits are prepared. An optimum at clarifying effect, also opposite slimy colloidal turbidities, which are smaller than 0,1¬, on the one hand and highest possible quantity achievements on the other hand, are the requirements, which are determined by the selection of the appropriate Celite filter aid must be met. Highest purity and chemical inertness combined with the consistent quality of the Celite filter aids guarantee that the product to be filtered is not contaminated in its chemical composition. composition is still affected in its taste or smell. (Diatomaceous earth is also the starting material for Celite specialties such as functional fillers, absorptive silicates, carrier material for chromatographic work, catalyst carriers).

Cross-Flow-Membrane Technologies (• Microfiltration • Ultrafiltration • Nanofiltration • Reverse Osmosis): we realize technical solutions with products and components of our principals and distribution partners – from spiral wound membrane elements via tubular membrane and hollow fiber elements to ceramic and metal sinter modules.

Unlike Celite diatomaceous earth filter aids, which consist of almost pure silica, Harborlite perlite filter aids are made from volcanic obsidian rock by thermal expansion. Chemically, it is aluminum silicate, which is nearly as inert as silica. In their structure, Harborlite-Perlite filter aids correspond to Spherical fragments that do not have the same porosity as the filigree skeleton of the diatoms. Accordingly, Harborlite perlite filter aids cannot be expected to have the same clarifying effect as Celite diatomaceous earth filter aids at the same flow rate. In three European plants, IMERYS manufactures in accordance with the most modern processing methods, we produce high-quality perlite qualities that are a useful addition to the diatomaceous earth filter aid program.
