Liquid poly aluminum chloride
PAC is an inorganic macromolecule flocculant whose chemical formula
[AL2 (OH) nCL6-n] m, where n≤5, m≤10, where m represents the degree
of polymerization, n is the PAC product Of the neutral degree. This
product is mainly used for the purification of tap water and
industrial sewage and special water treatment (such as water,
printing and dyeing sewage, including PB, CR highly toxic heavy
metals and F-containing sewage, etc.), in addition, can also be
used in precision casting, medicine, paper, Leather, thermal and
First, PAC301 product performance advantages: As the industrial
wastewater with high SS, COD high, BOD high characteristics of the
performance of poly aluminum chloride made higher than the
requirements of aluminum sulfate.
This product has the following characteristics:
--Both excellent settling performance and flocculation performance.
--For a variety of different concentrations of wastewater should be
adaptive, decolorization, detergency.
--Conducive to re-use of waste water, with environmental benefits.
--Simple operation, easy to use, saving manpower and resources.
--Low cost, with economic benefits.
Second, the product technical indicators: PAC301 product quality in
line with national standard GB15892-2003 water treatment agent in
the relevant provisions.
The molecular structure of this product is inorganic polymer
compounds, in the molecule, aluminum is the central ion, hydroxide
and chloride ions are ligands, through the hydroxyl from the bridge
polymerization as a complex of the population, the suspended solids
in the water Strong adsorption, but also to the pigment, so as to
achieve the purpose of purification.
Third, the use of PAC301: As the PAC301 PH value of 3.5-5, with a
slight acidity, need to use acid-resistant drug pool storage.
PAC301 has two kinds of use, according to the wastewater monitoring
index analysis to choose to use.
The first method: PAC301 directly added to the original liquid
method. PAC301 acidic, so pay special attention to the original
drug pump selection. In general, the ability to use a certain
degree of acid metering pump, according to the quality of water
treatment effect to adjust the dosage.
The second method: PAC301 dissolved use.
1, the conventional intermittent dissolving method, in the 20-30
minutes after stirring can be used.
2, continuous dosing, PAC301 products in the mixed dilution 5-8
times after a special mixer and mixed pump, you can use. Dosing
points / Dosage: Dosing points and dosages are key factors in
determining whether or not PAC301 is economical and must be
determined in practical trials. In the wine, paper, PAC301 dosage
is generally between 1.2-1.3 ‰.
Fourth, note: PAC301 in normal use and transportation process,
contact with this chemical should be routine cleaning, the product
has a certain acid.
Fifth, the product packaging: PAC301 products are two kinds of
packaging: 30 kg plastic drums and 6 tons to 36 tons of canned.
Shelf life: 16 months.
