Anthracite filter using high-quality coal as raw material selection, crushing, screening, and twice made the appearance of shiny, spherical, high mechanical strength, good compression performance, chemical stability, non-toxic substances Anthracite plant, resistant to abrasion, not dissolved in acid, neutral and alkaline water, the other anthracite particle surface roughness produce anthracite filter, a good adsorption capacity, porosity (≥52%), a higher-containing sewage ability, because light anthracite filter characteristics, the required backwash low intensity, can save a lot of backwash water and electricity. Spirit greatly accelerates this taught you how to detect Anthracite hydrochloric acid soluble rate: first, the sample is washed with distilled water Anthracite Anthracite, with 105-110 ℃ drying stage dried sample to constant weight ( Quality does not change), then the amount of the dried sample taken after G50 grams into 500 ml beaker. The second step, one volume of pure hydrochloric acid and 1 volume of distilled water mixed, 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, 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.
