The chemical industry has a broad spectrum of applications and needs highly efficient and economic liquid-solid separation solutions. Leading chemical producers are interested in product purity, high yield, low operating cost as well as waste minimization to meet sustainability goals.

In addition to our woven fabrics, we offer hardware spares such as filter press platesmembranes and disc elements.


  • Phosphoric acid
  • Potash

The most commonly used filters are horizontal vacuum belt filters and rotary pan filters. Clear Edge understands all aspects of your production and our offerings are a result of collaborative efforts with equipment manufacturers and our daily work in the field with our customers.

Clear Edge’s range of filter fabrics for agrochemical products is woven in our ISO accredited facilities and has been compiled with the rigours of these processing plants in mind. Whilst parameters such as fabric weight, permeability, weave pattern and yarn type vary to optimise the filtration performance, our filter media is always crafted to be as robust and easy to install.

Phosphoric Acid

Depending on origin and quality of the phosphate rock process conditions, particle size may vary considerably and this inevitably affects filtration rates. Due to desired high flow rates, monofilament fabrics are invariably selected, either in Polypropylene or Polyester, depending on customer priorities for filtration and service life performance criteria.

We have been working with phosphoric acid producers for many years to achieve the best filtration results under different process conditions and varying raw material qualities. We will help you find the best balance between acid quality, yield, cost, service life of filter media and filtration performance.

Clear Edge has been a filtration partner to the pigment and filler industry for many years. Our proprietary coated media fabrics allow for surface filtration of very fine particles and excel conventional media in performance and productivity.  Discover Coreflo™, the welded barrel neck and Clear Edge coated media Azurtex™ / Primapor™

  • Precipitated Calcium Carbonate
  • Precipitated Silica
  • Kaolin

Fillers and precipitated silica for the tire industry are amongst the fastest growing segments in the industry. Clear Edge offers a wide range of filter media options in conjunction with site specific process evaluations designed to meet the customer needs for high quality, throughput and process efficiency.


Filtration of very fine particles and fast throughput is a challenge in the pigment industry. Clear Edge has developed unique solutions for this market segment. Azurtex™ and Primapor™ are landmarks in pressure and vacuum applications in the production of coloured pigments.

Whether your site’s goal is to improve the efficiency of the de-watering of pigment slurry or to debottleneck your process to release the factory’s full potential, Clear Edge has helped achieve these goals for many pigment producers using our coated media fabric.

Azurtex™, in combination with Coreflo™, offer a unique solution for chamber filter presses as they guarantee long service life paired with the highest productivity and ease of installation. Coreflo™, the welded barrel neck, provides excellent mechanical stress properties with no needle-holes so solids can effectively bypass the media.

Titanium Dioxide

Clear Edge has customers around the world producing titanium dioxide via the sulfate or chloride process. We have been servicing the TiO2 industry over many decades and are considered as having the best available technology. Fabric selection is scientifically based on our extensive knowledge of the thermal, chemical and mechanical conditions found in the applications. Vertically integrated manufacturing ensures the highest standard of quality at every stage. In addition, our fabrication team has developed smart solutions for the fast and simple fitting of Vacuum (Moore) Leaf bags used in the TiO2 industry.

The Sulfate Process conditions and equipment types vary considerably for each filtration stage including from plant to plant. The ilmenite ore consists of black sand or rock and consequently, the first part of the manufacturing process is often referred to as the black section and the second part the white section, although the division is not always obvious.
