The Relationship

TrikotAC filter aids is a combination of a pre-coating material PreKot™ with two adsorbents; activated carbon and lime and their characteristics were investigated in this study. TrikotAC was formulated into three different weight ratios of 5:1:94, 10:1:89 and 10:5:85, respectively. The relationship between adsorption properties and characteristics of the formulated materials particle size distribution, particle density, bulk density, and BET surface area were investigated. The results showed that the adsorption capacity for TrikotAC 10:5:85 (11.88 mg/g) was higher than for the other formulated filter aids samples, and the formulated filter aids material TrikotAC showed promising characteristic as a filter aids and adsorbent for organic compound in fabric filtration system.

Filter Aids

Fabric filters are extensively used as an air pollution control system for its high efficiency to collect particles from gaseous stream. The system is commonly installed in many incineration plants as the means to control dust and gaseous emissions. Unfortunately, their applications in these facilities are short lived due to wear and tear of the fabric media. This is because the fabric filter is not adequately conditioned before it is put up into service. A simple technique is to apply so called ‘pre-coat’ material to coat a layer of inert material onto the surface of the fabric as a ‘barrier’ for protection as well as to allow a uniform air flow passing through the filter media. In this regard, a newly formulated filter aids material known as PrekotAC, not merely acts as an adsorbent for flue gas cleaning but also an efficient dust separation agent in a fabric filter system. A mixture of PreKotTM:Activated Carbon of 40:60 (%weight) was found to be the most preferable combination with its particle size distribution between 75 and 600μm, which is bigger size fraction than the original materials.

Abstract Solid-liquid filtration processes are crucial for the production of beer. Clarification of the green beer generates a clear and bright product with extended colloidal and microbiological shelf live. Conventionally, clear filtration is based on pre-coat filtration using filter aids, such as diatomaceous earth (Kieselguhr). However, the application of Kieselguhr requires strict adherence to occupational safety and health protection, as it is classified as a hazardous substance by the World Health Organisation and can lead to lung diseases. Furthermore, significant amounts of waste filter aids are generated. An alternative to pre-coat filtration is microfiltration that avoids the generation of hazardous wastes. Microfiltration can also be applied in beer yeast treatment. This article highlights major concepts and restriction of the filtration processes.

UK power stations have generated wet radioactive wastes, principally from operation of treatment plants for cooling pond water and liquid effluents. These include ion exchange resins, filter backwash sludges, flocs, pond sludges, filter aids, and miscellaneous oily sludges. To treat these wastes, it was concluded that mobile plants offered significant benefits compared with the alternative of constructing fixed installations. NSG Environmental Ltd designed and built a Mobile LLW Solidification Plant, which we have operated on behalf of BNFL Environmental Services and its predecessors for over twelve years. Since commencing active operations in 1991 the plant has successfully performed 28 campaigns on 13 nuclearlicensed sites. A total of nearly 3,000 drums of active waste have been processed during those campaigns. There have been no failures to solidify wastes, no excessive doses to operators and no transport incidents.
