Abstract
This review covers research articles published in 2017 on topics relating to physico-chemical processes for water and wastewater treatment. The paper divides into nine sections, i. e., membrane technology, ion exchange, capacitive deionization, granular filtration, coagulation/flocculation, sedimentation, flotation, oxidation and adsorption. The membrane technology part includes six parts, including microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO), forward osmosis (FO), and membrane distillation (MD).
