With the rapid development of the titanium industry,titanium coagulants have received wide attention.Titanium xerogel coagulant modified and prepared with a sol-gel method has high stability and can form large flocs in a short time,which make it a potential alternative to iron and aluminum salts for water treatment.The application potentials of titanium xe-rogel coagulant were analyzed emphatically by taking the development history and current research status of titanium coagu-lants into consideration.Titanium xerogel coagulant can be applied in many scenarios to solve the problems that met in iron and aluminum coagulation:treatment for low temperature and low turbidity water,algae-containing water,dyeing wastewater and pretreatment for membrane filtration.In addition,the application cost of the titanium xerogel coagulant might be reduced through compounding use with traditional coagulants or sludge recycling.
Key words: coagulant; titanium salt; low temperature; low turbidity; membrane filtration
