Coagulation performance of polyaluminum silicate chloride (PASiC) for water and wastewater treatment
A series of polyaluminum silicate chloride (PASiC) composite coagulants were prepared by two approaches: (1) hydroxylation of the mixture f AlCl3 and fresh polysilicate (PASiCc); (2) hydroxylated polyaluminum chloride (PAC) combined with fresh polysilicate (PASiCm). Laboratory xperiments were conducted to evaluate PASiC in comparison with PAC for the coagulation of water and wastewater and to i...
متن کاملOptimum conditions for arsenic and fluorine removal by coagulation with polyaluminum chloride
In the Centro de Ingeniería Sanitaria a process named ARCIS-UNR was developed for arsenic and fluorine removal from groundwater by means of coagulation with polyaluminium chloride (PACl) and double filtration. A treatment plant for 11,200 inhabitants was designed. During monitoring of the plant it was needed to get more data regarding removal mechanisms and relevant variables in coagulation-ads...
متن کاملSurface-retained organic matter of Microcystis aeruginosa inhibiting coagulation with polyaluminum chloride in drinking water treatment.
Algogenic organic matter produced by the excess growth of cyanobacteria in semi-closed water areas causes coagulation inhibition in drinking water production. In this study, hydrophilic substances of Microcystis aeruginosa, which were mainly composed of lipopolysaccharide (LPS) and RNA, were prepared, and the involvement of these cyanobacterial hydrophilic substances in coagulation inhibition w...
متن کاملDisseminated intravascular coagulation and coagulation disorders.
PURPOSE OF REVIEW An update on recent developments in diagnosis and treatment of disseminated intravascular coagulation. RECENT FINDINGS Disseminated intravascular coagulation is defined as a typical disease condition with laboratory findings indicating massive coagulation activation and reduction in procoagulant capacity. Clinical syndromes associated with the condition are consumption coagu...
متن کاملHemolyzed Samples Should be Processed for Coagulation Studies: The Study of Hemolysis Effects on Coagulation Parameters
BACKGROUND Rejecting hemolyzed specimens received for coagulation studies is advised by the Clinical and Laboratory Standards Institute. Receiving such specimens is a common phenomenon in many laboratories. The true impact of hemolysis on coagulation studies is little studied in clinical practice. AIM The aim of this work is to study the changes occurring in readings of prothrombin time (PT) ...
