Filtration Media Types

Water Filtration is broadly recognised as a means of providing high quality water. As easy as this seems, the actual filtration media along with the way it operates is much more complicated. Generally, water filtration media is categorised as depth filtration systems or screen filter systems. Depth filters hold on to particles within the matrix of the filter media as well as across the path of water flow. In comparison, screen filtration systems (also referred to as membrane filters) keep contaminants on the outer lining of the filter systems.

Whilst depth filter systems tend to be graded depending on the size of the actual contaminants they retain, membrane layer filter systems are generally graded via pore sizing’s.

Filter Media Materials

Filtration media is constructed from organic materials including cotton as well as wood pulp as well as out of artificial polymers like polypropylene. In-organic substances like glass aluminium oxide and silver.

Water Analysis Filter systems

Filter systems made use of in water analysis (blank) typically are employed for eliminating particles, recording and counting particular impurities or even for examining microbes. Normally, labs make use of water filtration media in spherical forms in linen varieties like filtration papers or even membranes or as enclosed devices like syringe filtration systems and also capsules.

Filter Papers

Cellulose and glass micro fibre media tend to be employed for fundamental qualitative and quantitative measurements. This standard process would be to take a filtration paper, calculate it’s base line weight, and then filter a particular volume of fluid through this, dried out the filtration paper and then calculate the actual weight again. Total suspended solids research is performed via a comparable technique.


Membranes are actually screen filter systems that get rid of contaminants usually within the sub-micron range. These are employed with regard to water filtration and enumeration of particles as well as microorganisms. Membranes put to use within laboratory work examination tend to be cast membranes. In water study membranes tend to be made use of for recording and examining microorganisms upon the surface area of the filtration system.

Enclosed Units

Filtration media tend to be enclosed within a plastic shroud making them ready to use filters. Good examples of enclosed water filtration units are syringe water filtration systems, capsule filter systems as well as filter cups. Enclosed water filtration products are extensively employed within the healthcare and pharmaceutical sector. These kinds of water filter systems are simpler to make use of as well as decrease cross-contamination involving samples. Capsule purification products are extensively employed whenever obtaining ground water samples.


Water Filtration techniques are extensively employed within water analysis laboratories. Filtration papers tend to be employed in total suspended solids research. Membranes tend to be employed as matrices with regard to collecting and enumerating organisms. Encapsulated water filtration products provide the efficiency as well as simplicity for the purpose of sample preparing prior to analysis.
