The article critically reviews the applications of biopolymers in the area of water treatment. A number of biopolymers were reported for their flocculation behavior for treating the wastewater and making it suitable for various industrial as well as agricultural purposes via chemical alteration onto its backbone. Wastewater treatment was followed by flocculation process using standard ‘Jar test protocol’. Minute quantities of dosage were found be ideal to diminish the organic, biological and suspended loads from wastewater sample. The process of flocculation using biopolymers was also found economically suitable compared to other various processes applied in water treatment.

Flocculation Process

Ploy-high-ferric-silicic coagulant was prepared using the fly ash extract and potassium ferrate. The flocculation process of treatment lead wastewater by this coagulant with various Si/FeO42- ratios and salt-basicity at different pH and dosage were studied by jar test. The results showed that color, turbidity and Pb2+ removal efficiency are excellent and treatment effects are stable in treatment lead wastewater, especially the removal of Pb2+ has been up to 96% more. The comparison on coagulation between poly-high-ferric-silicic and other coagulants, the poly-high-ferric-silicic dosage is low and adapt to a wide PH. Therefore, by comparison, the poly-high-ferric-silicic is a superior coagulant in lead wastewater treatment.

Photocatalysis holds great promise as an efficient and sustainable oxidation technology for application in wastewater treatment. Rapid progress developing novel materials has propelled photocatalysis to the forefront of sustainable wastewater treatments. This review presents the latest progress on applications of photocatalytic wastewater treatment. Our focus is on strategies for improving performance. Challenges and outlooks in this promising field are also discussed. We hope this review will help researchers design low-cost and high-efficiency photocatalysts for water treatment.
