Differences in coagulation efficiencies between PACl and PICl
Journal AWWA, 2003 Laboratory preformed inorganic polymer flocculants—polyaluminum chloride (PACl) and polyiron chloride (PICl)—were compared for their coagulation efficiency according to various basicity (B) values. Conventional jar tests were combined with electrophoretic mobility (EM) measurements.

Optimization of PACl dose to reduce RO cleaning in an IMS
Desalination, 2008 Abstract In order to ensure stable treated water quality and to reduce chemical costs in any treatment plant it is necessary to study and optimize the coagulant dosing control (CDC). This research focused on the affects of coagulant in the integrated membrane (UF & RO) system employed for industrial water production.

Coagulation of micro-polluted Pearl River water with IPF-PACls.
Journal of environmental sciences (China), 2004 Water samples collected from early March 2001 to the end of April 2002 at the branch of Pearl River around the Guangzhou City were analyzed for its micro-polluted characteristics. The coagulation behavior of polyaluminum chlorides (PACls) was then examined focusing on the effect of primary water quality and speciation distribution.

Journal of Hazardous Materials, 2013
In this study, we investigated the relationship between water characteristics and removal of natural organic matter (NOM) using polyaluminium chloride (PACl) and a newly developed coagulant obtained by hybridising PACl with chitosan (PACl-chitosan) for two different types of water. Using UV-visible spectroscopy analysis, we showed that PACl-chitosan is

Dynamic analysis of coagulation with alum and PACl
Journal AWWA, 1998PACl more effectively coagulates fine particles than alum.The coagulation kinetics of polyaluminum chloride (PACl) and alum applied to kaolin clay suspensions were compared in batch experiments. Increasing aluminum (Al) dosages reduced the time required for particles destabilization and increased the rate at which the number of primary particles ...

Characteristics of BPA removal from water by PACl-Al13 in coagulation process
Journal of Colloid and Interface Science, 2009This paper discussed the coagulation characteristics of BPA with polyaluminum chloride (PACl-Al(13)) as coagulant, examined the impact of coagulation pH, PACl-Al(13) dosage, TOC (total organic carbon) and turbidity on BPA removal, and analyzed the possible dominant mechanisms in water coagulation process.

Membrane fouling is a bottleneck issue that hindered the further application of ultrafiltration technology. To alleviate membrane fouling, coagulation-ultrafiltration (C-UF) process using polyaluminum chloride (PACl) and PACl-Al13 with high proportion of Al13O4(OH)247+ as coagulants, respectively, were investigated at various pH conditions.

Properties of Microfiltration of Humic Acid Solution Flocculated with PACl
KAGAKU KOGAKU RONBUNSHU, 2011PACl（ポリ塩化アルミニウム）で凝集処理したフミン酸溶液の精密濾過の性能を，濾過速度の逆数と単位膜面積あたりの濾液量との関係を表す実験結果に基づいて決定した濾過ケークの平均ケーク比抵抗αavによって評価した．pH 5では，PAClを過剰に添加すると，凝集フロックが再分散してαavは顕著に増大した．シリンジフィルターによるフミン酸の初期透過率の実験データに基づき，フロックの再分散によって生じたサブミクロン粒子量の増加が，αavの増大を引き起こすものと推察された．このことは，シリンジフィルター試験で測定した初期透過率が，凝集・膜濾過特性の簡易評価に利用できることを示す．また，pH 7での凝集操作やベントナイトの添加を行うと，凝集フロックが再分散しないPACl添加濃度域が拡がることによって ...

Interaction of PACls with sulfate.
Journal of environmental sciences (China), 2004This article discusses the influential factors on Al13 separation considering the interaction of sulfate with various polyaluminum chloride (PACl). The experimental results showed that the basicity (B = [OH/[Al]), the concentration of PACl and Al/SO4 ratio exhibited significant roles in the PACl-sulfate reaction.
