The conversion values in Table 1 is obtained by converting the diluted amount of chitosan and modified rectorite into the corresponding amount of 0.5% chitosan without dilution and modified rectorite without dilution, and then converting the newly obtained 0.5% chitosan: 2% polyaluminium chloride
: modified rectorite ratio into ml.
Having witnessed the benefits of peristaltic pump technology first hand when a Qdos model was recently installed at Welsh Water's Eign plant in Hereford for the back-end dosing of polyaluminium chloride
at 12 l/h, the company thought this might also be a good solution for front-end ferric sulphate dosing.
Aluminium sulphate (VI) (SAL), polyaluminium chloride
(PAX XL-60) and iron (III) sulphate (VI)--PIX-112, dosed in the form of water solutions were used as coagulants.
A comparison of the performance of polyaluminium chloride
(PACL), Ferric Chloride (FeCl3) in removing turbidity and organic matter.
Edinburgh Sheriff Court heard that polyaluminium chloride
was wrongly mixed with a swimming pool disinfectant, sodium hypochlorite, which produced toxic chlorine gas.
Kemira Water Solutions (Chongqing) Co Ltd, of which Kemira owns 80%, will invest in a new production line for the manufacturing of polyaluminium chloride
, with a capacity of 20,000 tons per year.
Another method that enables to remove fluoride from water is precipitation with such coagulants as aluminium sulphate and/or polyaluminium chloride
The joint venture, Kemwater (Yixing), will have an annual production capacity of 55,000 tonnes of liquid polyaluminium chloride
and 10,000 tonnes of solid PAC.
The process is aided by the addition of a coagulant chemical (polyaluminium chloride
) and polyelectrolyte with pH adjustment by hydrochloric acid or sodium hydroxide depending on the raw water conditions.
Thus, this work optimized the process route using SCML to produce inorganic polymer flocculants (IPFs) polyaluminium chloride
