liquid poly aluminum chloride 18 % pac for water treatment
factory supply high-qualiy liquid poly aluminium chloride10% 13% 18% for water treatment pac is a kind of inorganic macromolecule flocculant. through the hydroxyl ion bridging function and the polyvalent anion polymeric function, it produces large molecular and high electricity inorganic macromolecule.poly-aluminium-chloride (pac),pac 18 is based on highly charged aluminium which results in lower dosage and therefore reduces sludge volume and ph adjustment demand. it also improves solids and/or phosphorous removal over conventional coagulants. pac 9% hb: high-basicity liquid pac, containing 9 ± 0,5% al 2 o 3, specific for potable waters.
poly aluminium chloride (pac) water treatment chemical
poly aluminium chloride (pac) , the white or yellow powder, is an inorganic polymer coagulant. compared with traditional inorganic coagulants, fengbai poly aluminum chloride flocculation precipitation speed is fast, the ph value applicable range is wide, water purification effect is obvious and non-corrosive to pipeline equipment.polyaluminium chloride suppliers manufacturers,the andhra sugars limited guarantees minimum, 16.5 18.0% purity of al 2 o 3 in liquid pac 18, 13.5 14.5% purity of al 2 o 3 in liquid pac –14 , 9.5 10.5% purity of al 2 o 3 in liquid pac -10 and 10.2 10.5% purity of al 2 o 3 minimum 64% basicity in high basicity pac –10. quality control lab is equipped with most modern

polyaluminum chloride (pac) geo specialty chemicals
the lowest basicity commercial pac is are about 10%; most pac is are in the medium to high basicity range (50-70%). at the top of the scale is aluminum chlorhydrate (ach): at 83%, it is the highest stable basicity pac available. (ach is simply a special species of pac more about ach in the next section).kr101409870b1 method of preparation for high basicity,the present invention relates to a method for manufacturing a high-basicity polyaluminum chloride coagulant and a water treatment method using the same. the method for manufacturing high-basicity polyaluminum chloride comprises the steps of: (a) generating a first reaction product of polyaluminum chloride (pac), which is represented by chemical formula (1), having the content of al_2o_3

polyaluminium chloride process, properties and functions
poly-aluminium chloride(pac)is a kind of highly effective water purificiant, which is wildly used in the purification of table water, industry water, industry circulation water and wasted and polluted water from pharmacy industry, paper making industry and printing and dying industry, as well as life wasted water. synthesis and speciation of polyaluminum chloride,aluminum chloride (pac) may be produced by adding base to aluminum chloride until an empirical formula ofal(oh (with n from 1 .o to 2.5) is achieved.

preparation and characteristics of polyaluminium chloride
clay-brine process employing activated clay, nacl, hcl, and hf as raw materials is the primarily advanced technology to synthesize cryolite in the present industrial grade. however, plenty of byproducts of fluorine-containing waste hcl at the concentration of about 10%~12% could not be utilized comprehensively and are even hazardous to the environment. this work proposed a new ,application of coagulation/flocculation in oily wastewater,sun et al. (2017) reported that under optimal g values and dosage, the satisfactory removal effects of cod (chemical oxygen demand) and turbidity by pafsi ((poly-aluminum chloride silicate) were 94.4% and 94.1% at ph 7. accordingly, oily wastewater should be kept in the range of alkalescence as mentioned above, just being helpful for coagulation.
