Anthracite Filter Media are filtration materials for turbidity and SS removal. Since the specific gravity is lighter than that of Filter Sand, it is much used in combination with Filter Sand in dual-media filtration, to consist reverse grain layers after backwashing. In addition, because of high content carbon of this product, it has high resistance to various chemicals and high physical strength so that it is widely used for city and industrial water purification.
C & S Brand Filter Coal has a history of performance over the last 10 years which substantiates its uniqueness as a filter media for water treatment. Prior to the development of C & S Filter Coal, anthracite coal was traditionally specified for filter media, primarily because of the reputation that some of the deposits of this class of coal had for hardness.

Advantages of C & S Brand Filter Coal (Anthracite)
(1) Competitive Pricing
Although C & S Filter Coal is a unique product, it is very competitively priced in relation to other anthracite coal type media. Prices are negotiable depending on quality and specifications.
(2) Superior Particle Size Grading: Very Low Uniformity Coefficient and Minimal Fines Content
The very low uniformity coefficients of C & S Filter Coal, coupled with an angular particle shape and very low fines content result in maximum void space per cubic meter of media. Our standard U.C. is 1.3, the lowest standard U.C. in the industry. We can supply an even lower U.C. if required, down to 1.2, at a slightly higher price than our standard grade. We also supply U.C.’s up to 1.4 at a slightly lower cost, but do not recommend values above 1.4. The low fines content also increases void space, minimizes nuisance due to dust, and means that only a minimal amount needs to be over-ordered to allow for removal of fines by scraping during commissioning (typically 2% instead of up to 10% often used with other brands).
(3) Optimum Specific Gravity
The coal has a specific gravity of 1.45. Compared with American anthracite coals which have a higher SG, C & S Filter Coal requires a lower backwash rate for the same Effective Size. This permits a saving in backwash pump capacity and reduces the quantity of backwash water required.
(4) High Durability & Stability, with Established Track Record
Of equal importance to the superior grading of C&S Filter Coal is its demonstrated ability to maintain its original properties over many years of service. This was initially demonstrated in laboratory trials by large independent Australian Water authorities. High durability was established by many days of continuous backwashing in pilot columns to stimulate years of use, and by the use of standard hardness tests, e.g. Watson-Hawksley Friability. (Method available on request) More importantly, the monitoring of performance in full scale plants has confirmed that there has been virtually no change in Effective Size and Uniformity Coefficient and almost unmeasurable change in the volume of media within a filter, over an eight year monitoring period. (See letter from Hunter Water Corporation) The media is chemically stable, and monitoring has confirmed that no substances has been detected in drinking water filtered through C&S Filter Coal that could be attributed to leaching from the media, and there is no detectable level of phenol.
(5) Wide Industry Acceptance
C&S Filter Coal is widely used by most Australian water authorities and is by far the market leader in coal/ anthracite type filter media in Australia, with growing export markets. Established customers continue to purchase C&S Filter Coal for each new project.High Product
(6) Consistency & Quality Control
Our product consistency begins with the raw material used, which is always taken from the same coal deposit. This deposit has been quite carefully selected for its ability to meet all of the criteria necessary in a top quality filter media. Each step in the production process is closely monitored by qualified staff applying a strict and effective quality control system, which is certified to the international quality standard ISO9002 (Australian Standard AS9002). Production testing for Effective Size and Uniformity Coefficient is carried out on every tenth cubic meter of media produced.
