    • Buyers Guide

    Here at Cleanse Filtration we are looking to lead the way with innovative ideas and solutions in the design and manufacturing of a wide range of industrial filters. We have produced this buyer’s guide to enable you to be more familiar with the terms and processes of filtration and the products and services available through our company.
    In the ever-changing world of filtration, we are all aware that the process and practice of Filtration can be complicated and often boring. So here we have your easy to use guide, to replace those over-complicated textbooks, or having to spend hours searching the internet. A filter is basically a device for separating one substance from another, and to that it requires the placing of filter medium in the way of the fluid flow, so as to trap the solids in some way. The filter then becomes any contrivance that is able to hold the filter medium in the best way to achieve purpose of the filter process.
    The process of filtration and separation falls into four categories:
    • Solids-Gas
    • Solids-Liquids
    • Liquids-Liquids
    • Solids-Solids
    Each type of separation and its function performs a specific form of separation according to its purpose in industry. Below is a list of variables which enable manufacturers to use the most suited components to serve their environmental purpose: Filtration variables:
    • Flow rate
    • Differential pressure
    • Viscosity
    • Contaminant
    • Flow conditions
    • Compatibility
    Main industry users:
    • Water and Sewage – Purifying drinkable water and sanitizing sewage
    • Chemical – Separating useful chemicals for production
    • Oil Refineries – Refining oil by removing unwanted particles
    • Power Generation – Reducing high level pollutants
    • Food and Beverage – Purifying flavors of drinks
    • Pharmaceuticals – Accuracy is essential to enable no contaminants are found in remedies
    • Mining – Air filters are a necessity to protect human life when confined below ground
    • Paper – To purify the paper content and to protect workers from harmful fumes
    • Plant Machinery – Cleansing fuel output and to prolong life and efficiency
    Something that goes unrecognized is that filtration products keep us healthy! by keeping the air in our working and social environments clean. Filters are often purposely made to be bio-degradable where possible in order to protect our environment and decrease levels of landfill. “Environmental issues are of growing concern for government and industry” (Filters and Filtration Handbook 4th Edition T. Christopher Dickenson, 1997). Here at Cleanse Filtration  we look to re-use materials and products to further protect our environment, one of our many services is to backwash and cleanse your filter to prolong its life and effectiveness, a process which can be undertaken on most of our filters, please call us to find out more information or any other queries you may have.
    • ENVIROMENTAL ISSUES The Cleanse Filtration team is committed to saving our environment through production, operation and disposal of filters.
    • Manufacturing– Low energy papers, air pressurized machinery; degradable materials are used where possible.
    • Operation– A large range of our products are applied to operations whereby pollution is reduced or air is purified in the working environment, a catalyst converter in a companies and air handling units are two examples.
    • Disposable –Filters such as automotive air filters are not constructed from metals, in an attempt to reduce landfill levels.
    FILTERS ARE ENVIRONMENT FRIENDLY AND RECYCLABLE! In the next chapter – Filter Media, we look at the medium of the filter, the component which allows the filter to separate particles and the varying differentials of each medium.
    “It is rightly said that the heart of any filter is the filter medium”, Handbook of Filter Media, D.Purchas 1996. Unless it is fitted with the correct medium, a filter cannot perform its process. Each type of medium is suitable to different environments and conditions. Every form of media can be enhanced by choosing an optional extra, which increases both effectiveness and stability to suit its function. The number and variety of mediums is huge, they range from metal sheets to paper to plastics and beyond. The type of medium selected depends upon the size of the catchment particle and the conditions (e.g. temperature) the filter is exposed too. A successful medium must incorporate many factors to carry out a positive function. These can be placed into three headings, listed below:
    1. Machine orientated properties – conditions the filters medium is exposed to, which restrict the use of particular mediums in certain filter types.
    • Rigidity
    • Strength
    • Resistance to abrasion
    • Stability to vibration
    1. Application orientated properties – the compatibility of the medium to its environment.
    • Health and Safety
    • Absorptive Characteristics
    • Adsorptive Characteristics
    • Static
    • Disposability
    • Cost
    • Chemical stability
    • Thermal stability
    • Dynamic stability
    1. Filtration specific properties – the ability to achieve its task.
    • Retention efficiency
    • Resistance to flow
    • Dirt holding capacity
    • Smallest particle retention
    All three headings and their incorporates act as test of function. Testing of the medium is critical, for example when filtering dust the medium must have a high dirt hold capacity, and be made from fabric so capable of removing sub-micrometer dust and fume particles.
    PROCESS FILTER (FILTER HOUSINGS & STRAINERS)
    • Petrochemicals, pharmaceuticals, Food and Beverage, Chemical, Water and Sewage
    • Oil Refineries, cement, paint industries etc.

    All filter types are made up of different components, dependent upon their working environment and parameters. The components used differ in order to satisfy thermal, rigidity and chemical properties as well as to suit level of dirt hold capacity and future re-usability. Remember all filter types are environmentally friendly, both through their use and their disposability.

    Absolute Rating is a value associated with a filter that represents the size of the smallest particle completely retained.

    Nominal Rating is arbitrary value for the performance of a filter, expressed by efficiency of filter in terms of percentage retention of specified contaminant of given size.

    Absorptive the taking in, incorporation or reception of gases, liquids, light or heat.

    Adsorptive the retention of gas, liquid or solid on a surface due to positive interaction (attraction) between the surface and the molecules of the adsorbed material.

    Air to Cloth Ratio is the flow rate divide by the volume of the filter.

    Beta Rating is the ration between the number of particles per unit volume above specific size in the suspension upstream of the filter to the same parameter in the flow downstream of the filter.

    Chemical stability is defined as the ability of a filter’s materials of construction to resist chemicals so that the filter’s function is not adversely affected, and the filter material does not shed particles or fibers, or add extractable.

    Contamination – A substance that is either present in an environment where it does not belong or is present at levels that might have detrimental consequences upon its function.

    Dirt holding capacity – Amount of dirt or particles retained by a filter in grams per unit area of the filter medium.

    Filter Efficiency is the ratio of particles trapped by a filter over the total number of particles found in the air upstream of the filter. A count of the downstream particles is often used to determine the number of particles trapped by the filter.

    FLOW Rate is a measure of the amount of filtrate that flows through a filter. It is related to the degree of contamination, differential pressure, total porosity, and filter area.

    Micrometer “micron.” It is a 1/1,000,000 of a meter. 60µm = approximately the diameter of a human hair.

    Pore Size Rating is the pore size of the filter determined by the diameter of the particle that it can be expected to retain with a defined, high degree of efficiency. Pore size ratings are usually stated in Micrometers (µm). Ratings can be stated as either nominal or absolute.

    Retention efficiency – Ability of a filter to retain particles suspended in a gas or liquid. Expressed as a percent of particles originally present.

    Thermal stability is the ability of the filter media and device components to maintain integrity and functionality at elevated temperatures.

    Viscosity – A fluid’s resistance to flow. Viscosity is used to describe friction of fluids.
