Diatomite filter aid is a new efficient powder filtration medium. At Xinhui, as a prominent diatomite products supplier from China, we offer a wide range of diatomite filter aids that come with excellent permeability and provide porous filter cake structure. Void content is up to 85-95%, ensuring that it reaches a high flow rate and can remove micro suspended solids.

Except concentrated caustic solution, our diatomaceous earth filter aid can be used for filtration of any kind of liquid without pollution. In addition, it is excellent for use on various media including filter cloth, filter paper, wire mesh, porous ceramics, etc., and provides perfect filtration performance on various filters. As compared with other filter media such as perlite, cellucotton, and more, our diatomite filter aids come with unmatched advantages.

Xinhui is a specialized manufacturer of diatomite filter aids, enjoying the rights to exploit two diatomite mines that have been proved to contain a reserve of about 10 million tons of diatomite. We own two digitalized diatomite production lines which ensure a 30,000 tons annual output of diatomite filter aids. Our domestic market share of this filter powder is up to 50% and it has been exported to various countries including South Korea, Australia, New Zealand, Russia, Thailand, India, the Philippines, etc. We accept batch order and offer samples to new customers as required.

Diatomite Technical Requirements
1. Sensory Requirements

Product Recommendation:
To improve filtration velocity and reach a best clarity during solid-liquid separation, we divide our diatomite filter aids into tens of models. Different filter media and filtration equipment need different models or combinations.

1. Diatomite Filter Aids Based on Permeability

Note:
1. Refer to technical instructions for detailed physical and chemical indexes of each model;
2. Model formulation principle: multiply the middle value of permeability by 100 and use the result as a mark. For example, if the middle value is 3.0, the mark is 300#. According our identifications, the model is RS300. 300# does not stand for a degree of fineness.

2. Low-Iron Sterile Diatomite Filter Aids in Beer Industry
Xinghui is the first company to successfully develop the low iron sterile diatomite filter aids used in beer industry. This product handles various problems of the industry caused by exceeding of iron ion during filtration process such as high turbidity, aged flavor, iron taste, etc. It makes a great contribution to further improvement of beer quality.
