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
