Spirit greatly accelerates this taught you how to detect Anthracite hydrochloric acid soluble rate: first, the sample is washed with distilled water Anthracite, with dry stage dried sample 105-110 ℃ to constant (quality is no longer change), then the amount of the sample after drying G50 grams, placed in 500 ml beaker. The second step, one volume of pure hydrochloric acid and 1 volume of distilled water mixed production of anthracite filter, dosage cup measure 160 ml of hydrochloric acid was added at the first step in a 500 ml beaker, and the sample was completely submerged. At room temperature, stirring two, still 30 minutes to be foamed. The third step, the hydrochloric acid solution is poured, repeatedly washed with distilled water and anthracite filter price, the whole process can not let the loss of sample until the washing water with PH dipstick test was neutral. The fourth step is to wash the samples were placed in constant weighing bottle, again at 105-110 ℃ oven dried to constant weight, weighing G1. Hydrochloric acid soluble rate formula: Hydrochloric acid soluble rate (%) = (G-G1) × 100. This will calculate how much hydrochloric acid soluble rate. So how much is the standard hydrochloric acid soluble rate it? Relevant provisions: drinking water filtration Anthracite hydrochloric acid soluble rate should not exceed 3.5%. Of course, this standard also applies to industrial water filtration with anthracite media. Anthracite laying will be impurities or those without good Anthracite fixed to jam live in? Yushchenko Xiao Bian very responsible person to tell you: do not have to tangle the issue, anthracite removal rate of 99%; long life, deal with large amount of water; promote the separation of turbidity and bacteria; excellent stability and reduce solidification easy to scale ; low specific gravity lower supporting thickness; about half the proportion of sand, less backwash water. Just before laying reasonably filled, scientific and rational grading late regular inspection, regular washing, generally big problem will not appear. Anthracite is characterized by: high fixed carbon content, high density, high strength, good appearance gloss, chemical stability, but also has better solids holding capacity, Anthracite has the following advantages: acid or alkali were in stable condition ; filtration speed. Chargeability stronger than anthracite sand anthracite filter production, with electric adsorption effect, can achieve high-speed filter; filter out high, Anthracite adsorption area wide, can filter out many pollutants, can reliably improve the removal of suspended particles. Anthracite filter does not contain toxic and hazardous substances, in acidic, neutral water is not dissolved.
