- •
Product-LDA was characterized as a cationic biopolymer with broad structure.
- •
Addition of LDA enhanced coagulation performance and decreased membrane fouling.
- •
LDA addition resulted in flocs with open structure and strong anti-shear ability.
- •
LDA introduced charge neutralization and absorption bridging effect.
- •
The coagulation aid effect of LDA was not affected by the type of metal salts.
