Anthracite filter criteria. 1. Purpose: water purification and filtration. 2. Scope: drinking water, industrial water, industrial waste water purification filtration. 3 features: Anthracite filter is used as drinking water filtration, acid / base filtration, oil separation and sewage treatment, which has the following advantages over other traditional media: (1) are stable in acid or alkali (2) filtering speed . Highly charged than the sand anthracite anthracite filter supply, with power absorption effects. Enables high-speed filtering (3) In addition to the high rate, anthracite filter adsorption area wide, can filter out more contaminants removal rate of 99% long-life (4), processing large amount of water (5) promote turbidity and bacteria Separation (6) excellent stability and reduce clotting easy to scale (7) reduced the proportion supporting low thickness (8) accounted for about half of the sand and water at least 4, when the backwash type: crushing of granular anthracite 5, Principle: The suspension of fine solid grains in water after dosing flocculation, membership to be filtered by the filter anthracite. 6. Specifications Performance :: bulk density (t / m3) 0.83 ~ 0.85; gravity (g / cm3) 1.5 ± 5%; fixed carbon ≥78% (except ash and moisture); hydrochloric acid soluble rate ≤3.5; volatile copies% ≤6-7; moisture% ≤3; clay content% ≤1.5; breakage rate% ≤0.7; wear rate% ≤0.5 Mohs hardness 3-4; backwash expansion 50% expansion; conventional particles: 0.8 ~ 1.8mm; 1 ~ 1.8 mm; 1.4 ~ 2.5 mm; 1 ~ 2 mm; 3 ~ 4 mm; 4 ~ 6 mm (according to user requirements screening) Packaging: 50 kg 850 kg 1000 kg anthracite filter, etc., are exported to Japan, Korea, Taiwan, the United States and other places. Anthracite filter using high-quality coal as raw material selection, crushing, screening, and twice made the appearance of shiny anthracite filter specifications, spherical, high mechanical strength, good compression performance, chemical stability characteristics of anthracite filter , non-toxic substances, wear resistance, in acidic, neutral, alkaline water, not dissolved, in addition anthracite particle surface roughness, good adsorption capacity, porosity (≥52%), containing a higher pollution ability, because lightweight, lower strength required backwash, can save a lot of backwash water and electricity.
