The coagulation-flocculation of TiO2 in aqueous suspensions of low and intermediate ionic strength was investigated as a function of pH, of addition of aluminum sulfate and of stirring the suspension. This process was ...

Anaerobic digestion applied to stillage usually results in treatment performances. However, effluents from anaerobic reactors still present a residual polluting load due to the presence of organic recalcitrant compounds. ...

Aluminum sulfate (AS) is widely used as a coagulant in conventional drinking water treatment facilities. Alternative coagulants are commercially available, including polyaluminium chloride (PAC). However, comparative studies ...

The dairy industry is a sector of great relevance worldwide and, uses billions of liters of water in its production. Linked to the large production, there is a large generation of effluents that without adequate treatment ...

Polyaluminium chloride (PAC) is a pre-hydrolyzed inorganic polymeric coagulant that is being used widely in the treatment of water supply and wastewater by forming a hard and heavy Al(OH)(3)* precipitate, in addition to ...
