POLYALUMINUM CHLORIDE | 101707-17-9 - ChemicalBook
This document provides information about a polyaluminum chloride (PAC) production process. It describes the advantages of the proposed improved PAC process over conventional processes, including producing PAC with higher concentrations and basicity. The key products are an 18% Al2O3 PAC and a 9% Al2O3 PAC. A typical plant would produce 30,000 tons of PAC per year. The process involves reacting ...

An effective control of the bacterium in activated sludge WWTPs can be accomplished by dosage with polyaluminium chloride (PAX-14). The purpose of this study was to investigate whether addition of PAX-14 affects surface properties such as the hydrophobicity of the bacterium and to study the exopolymers of M. parvicella that host surface-associated enzymes.

Get PriceCan polyaluminum chloride be used in water treatment?
In this study, synthesis and speciation of polyaluminum chloride (PAC) for application in water treatment was investigated using a colorimetric speciation method. It was possible to produce stable preparations of PAC solutions in which a relatively stable cationic polymer predominated.
Why is polyaluminum chloride a good coagulant for water treatment?
Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water .
What are the synthesis parameters of aluminum chloride hexahydrate?
The synthesis parameters were concentration of aluminum chloride hexahydrate (0.4 to 0.8 M), basicity ratio (2.0 to 2.4), reaction temperature (60 to 80 °C) and time (180 to 360 min). The performance of PΑC for water treatment was also investigated. The monomeric, medium polymeric and colloidal species of PAC were determined by Ferron test method.
What are the properties of polyaluminium coagulants?
An important property of polyaluminium coagulants is their basicity. The highly charged Al in the products is optimized for best performance for the different basicities of PAC. The low to medium basicity products (25% up to 45%) are excellent at reducing the turbidity while maintaining good phosphorus removal properties.
How does Contec produce polyaluminum chloride coagulants?
Contec produces a wide range of polyaluminum chlorides diversified by the value of the basicity and the aluminium content. The process can be divided in two steps: The reaction Where we can produce, in the glass line reactor, polyaluminum chloride coagulants with a low and medium basicity.
How long is polyaluminium chloride stable?
Polyaluminium chloride solution is stable for 5 to 6 months when stored at less than 50°C and is so ideal for bulk storage and dosing installations. The growth rate of polyaluminium chloride has been very impressive.
