Biopharmaceutical Filtration Services


In today’s biopharmaceutical market companies are facing stricter regulation laws than ever before. These laws ensure safe and effective drug production when manufacturing, generic and/or brand name medications, API’s, vaccines, etc. From lab bench testing and patenting to the full-scale production; these drugs must pass an extensive list of guidelines and regulation laws issued by the FDA.

At D & D Filtration we offer a wide range of products that meet and exceed, all of these sanitary standards. We have solutions for cell culture, chromatography, plasma fractionation, API’s, single-use systems and many more. These products include pharmaceutical and biopharmaceutical grade cartridges, housings, capsules, and media, D & D Filtration is a must for every step in your production line.

Industrial Filtration Services


There are a wide variety of process industry applications. Product line includes membrane cartridges, pleated cartridges, vessels, high-efficiency filter bags, melt-blown cartridges, stainless steel media and more. Process filter media provide contaminant removal from 0.04 to 840 micron, with efficiencies as high as 99.9+ percent.

The industrial market involves high-technology filtration products and services to the inks and industrial coatings market. The coatings industry produces high viscosity mixtures of resins, solvents, pigments and other additives that provide specific properties to the end product. Proper blending, mixing, and dispersion is necessary for quality coatings. Filtration of these fluids is key to removing gels, agglomerates, and other contaminants to assure the desired coating properties. An effective filter must not affect adhesion, color, grind specification or dispersion of the coating. Many coatings require filters that “classify” or allow desirable particles to remain while removing undesirable ones.

Filters perform these functions. They contain no silicone or other material that can adversely affect adhesion of coatings. D & D Filtration supplies the industrial coatings market with the best filtration solutions at the lowest cost of filter ownership available anywhere. Our filters also help ink manufacturers maintain pigment concentration and color, by removing contaminants and ensuring that grind standards are met.

Beverage Filtration Services

Food & Beverage

The Food and Beverage industry is a rapidly growing world market that draws upon core areas of our filtration expertise. Included within this market the broad range of products that require highly effective filtration in their manufacturing processes. These products include:

  • Water Filtration
  • Air/Gas Filtration
  • Steam Filtration
  • Liquid Filtration
  • Filter Housings
  • Mini-sized cartridges and capsules

Through our Technical, R&D and Customer Service Teams we offer a wide range of services to ensure total customer satisfaction. The production of food and beverages is important, although by no means the largest, component of the separation equipment market. The major anomaly lies in the production of drinking water, strictly the largest of the beverages, but in fact so large as to be in an end-use sector of its own, and therefore not included here.

  • Processing of meat, fish and their solid products (excluding oils and fats).
  • Processing of fruit and vegetables and their solid products (excluding oils, fats, and juices).
  • Processing of oils and fats from animal and vegetable sources.
  • Manufacture of dairy products (milk, cheese, etc).
  • Milling of grain, and manufacture of cereal and starch products.
  • Production of animal feedstuffs (i.e. food for husbanded animals, and domestic pets).
  • Production of bread, sugar, cocoa, and confectionary.
  • Processing of tea and coffee.
  • Production of beverages (alcoholic and non-alcoholic), including fruit and vegetable juices, and bottled mineral water.

Several of these sub-sectors are, of course, completely dry processes, but with a sufficiency of liquid processing in the other parts, and of utility filtration (pneumatics, hydraulics, and other operating services), enough to make this the fifth largest of the end-use sectors, utilizing almost all kinds of separation equipment. The process filters and centrifuges are used in the preparation of ingredients, in the production process itself, in the purification of products, and in the recycling or treatment of waste streams.

Microelectronic Filtration Services


Microelectronics are found everywhere from consumer electronics to satellites, from corporate data centers to microwave ovens. The Microelectronics market is fast-paced and cyclical, driven by the constant demand to supply new products that are ever faster, with higher capacities and smaller footprints. The manufacturing of the newest generations of IC chips would not be possible without effective filtration.

The microelectronics industry is a rapidly growing world market that draws upon core areas of our filtration expertise. Included within this market is the broad range of electronics products that require highly effective filtration in their manufacturing processes. These products include:

  • Semiconductors
  • Flat Panel Displays
  • Hard Disk Drives

In the Microelectronics Industry, filter process falls into three categories: Chemical Filtration, Photochemical Filtration, and Chemical Mechanical Planarization (CMP).

The filters used in semiconductor production processes need to provide the lowest possible levels of metals extractable and high particle retention efficiencies. However, since these processes combine the use of aggressive chemicals and high process temperatures, we have developed a wide range of fluoropolymer filters that possess high chemical and thermal resistance and are suited for all processes in the manufacturing of semiconductors.
