Backwashing consists of reversing the flow of water so that it enters from the bottom of the filter bed, lifts and rinses the bed, then exits through the top of the filter tank. The filter bed itself is a granular substance that is usually referred to as the filter medium.

A 100 kg. sample of ground calcite (GP40) composed of 99.95% CaCO 3 supplied by Asturiana de Calcitas, S.L. was treated to produce three distinct grain size distributions to form calcite/water separation medias for this investigation. One fraction of the sample was kept as it is, to constitute a “GP40-1” heavy media.

The reduction ratio of calcite for each milling parameter was calculated from the following equation: Reduction ratio ¼ F 50=P 50 ð5Þ where F 50 and P 50 are the mean particle size of the feed (μm) and the product, respectively.

Calcite can be effectively combined with Clack Corosex to combine the high flow neutralization properties of Corosex, along with the slower reacting low flow properties of Calcite, increasing the ability to correct low pH.

An experiment was conducted in Canoinhas, SC, in a randomized complete block design with three replications in 4 x 2 factorial arrangement. Four levels of gray calcite (0, 3, 6 and 9 t / ha) and ...

Depending on pH and service flow, the Calcite bed will have to be periodically added to as the dissolved calcite de pletes. As the Calcite¡¦s calcium carbonate neutralizes the water, it will increase hardness and a softener may become necessary after the neutralizing filter.

Deste modo, para que os níveis de dióxido de carbono que se perdeu sejam repostos, a equação química começa a evoluir no sentido de formar CO2, o que leva também a formação de calcite e assim à precipitação desta que, mais tarde, depois de uma deposição e de uma diagénese dá origem ao calcário.

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO 3).The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite".

Calcite will correct pH to a 7.2-7.4 range without overcorrecting and causing high pH spikes. calcite is ideal for pH levels as low as 6.0 When pH levels are below 6.0 calcite generally will not provide enough pH correction and that is where corosex comes into use.
