Description
一.Feature:
Taixi coal of Ningxia: Taixi coal is famous for made in taixi
town shizuishan city ningxia hui autonomous region. It has three
low index(low ash, low sulfur, low phosphorus), six high index(high
calorific value, high ratio resistance, high lump coal rate, high
chemical activity high clean coal, high mechanical strength), It is
a crown of domestic high-quality coal, exported to more than 10
countries Europe and America.
It is stable chemical performance, do not contain toxic substances,
wear resistance, acid, neutral and alkaline water shall not be
dissolved, and anthracite coal particle surface roughness, and a
good adsorption capacity, pore ratio (> 50%), a higher including
carrying capacity, because of the light, the back flush strength is
low, can save a lot of backwash water and electricity.
Anthracite filter material with quartz sand filter material used in
conjunction with China is the promotion of double rapid filter and
three layer filter, filter can filter the best materials. Is to
improve the filter speed increase unit area water yield and doubled
section carrying capacity, reduce the project cost and reduce
covers an area of the most effective way. Widely used in chemical
industry, metallurgy, thermoelectric, pharmaceutical, paper making,
printing and dyeing, food and other production before and after the
water treatment process.
Anthracite filter material USES:
Practical from general acid, and alkaline water purification
treatment, it is double, three filter indispensable water
purification materials, the technical indicators are reaching and
more than the ministry of construction (CJ/T44-1999 standard.
Filter principle: the water\'s fine suspended solid grain after
dosing flocculation, the anthracite filter material to
filter.
二．Application:
It is used for raw water and industrial water supply Europe
filtration purification treatment. When using the form of filter
according to determine if the use of parameters, general double
filter section of pavement thickness for 300-400 mm; Normal filter
speed 10-14 m/h, forced filter speed 14-1 8 m/h, Three layer filter
material pavement thickness 450 mm, normal filter speed eighteen to
twenty m/h, forced filter speed and ~ 25 m/h. Filter backwashing
with water wash, rinse with water vapor or surface
flushing.
Our filter media is made of Taixi anthracite by washing, chosen,
smash, repeatedly screening and so on procedures. It has nice
lustrousness, mechanical strength, resist compression, hard wearing
and steady chemical activity. Also, it has some separate-absorb
activity, which can absorb and disposal colour, stink, flavour and
minute organism in water, and applied to filter life water,
industrial water as well as municipal sewage. It is a nice material
for environment protection.
