Aluminum chlorohydrate (ACH) is a specific type of PACl with an Al:Cl ratio of 2:1 and a basicity of 83 percent. The common chemical formula for ACH is Al2(OH)5Cl [13]. For ACH, aluminum solubility between pH 7.0 and pH 10 is fairly constant. Below pH 7.0, however, aluminum solubility increases sharply (Figure 3) [16].

nanofiltration membrane fouling and control caused by residual aluminum

Nanofiltration Membrane Fouling and Control Caused by Residual Aluminum

It is reported that residual aluminum from coagulation pretreatment can increase membrane fouling in nanofiltration (NF) or reverse osmosis (RO) desalination systems. However, the membrane fouling mechanism of residual aluminum and the effective control measures are not very clear. In this study, the nanofiltration membrane fouling caused by poly-aluminum chloride (PACl), the inhibitory effect

Managing aluminum in membrane filtration - ROPUR

Ozgencil Haci look at the need to manage aluminum in membrane filtration processes for cost control by selectively sequestering dissolved Aluminum traces with chelating agents using the highest Antiscalant quality product. Membrane technologies such as reverse osmosis, nanofiltration, ultrafiltration have found wider acceptance in recent years.

Hexose sugars adsorbed on aluminum phosphate at a rate constant of ~5.34 ¡Á 10 2 L mol ?1 s ?1 were removed by flotation at the same rate of COD. The concentration of soluble aluminum was dependent on multiple reactions involving aluminum species and on the equilibrium between soluble and solid aluminum species.

The safe use of cationic flocculants with reverse osmosis membranes

a low molecular weight cationic polymer is often used in conjunction with an inorganic coagulant such as alum, aluminium chloride or ferric chloride, to gener-ate small flocs known as ¡®¡®pinfloc¡¯¡¯. This is usually fol-lowed by treatment with a high molecular weight anionic polymer which attaches to the now cationic
