Polymer flocculants are used to promote solid–liquid separation processes in potable water and wastewater treatment. Recently, bio-based flocculants have received a lot of attention due to their superior advantages over conventional synthetic polymers or inorganic agents. Among natural polymers, polysaccharides show many benefits such as biodegradability, non-toxicity, ability to undergo different chemical modifications, and wide accessibility from renewable sources. The following article provides an overview of bio-based flocculants and their potential application in water treatment, which may be an indication to look for safer alternatives compared to synthetic polymers. Based on the recent literature, a new approach in searching for biopolymer flocculants sources, flocculation mechanisms, test methods, and factors affecting this process are presented. Particular attention is paid to flocculants based on starch, cellulose, chitosan, and their derivatives because they are low-cost and ecological materials, accepted in industrial practice. New trends in water treatment technology, including biosynthetic polymers, nanobioflocculants, and stimulant-responsive flocculants are also considered.

“…From the observations, it can be seen that when the speed is higher than the optimum condition (> 20 rpm) it will cause a statistically significant decrease in the value of turbidity removal (P<0.05). This is due to the effectiveness of the disruptive force, resulting in floc breaking and less particle collision in the shear field [46].…”

The purpose of this study was to conduct a literature review to determine the understanding of current research on the use of Cassava Peel (CP) in the field of wastewater treatment, especially as a coagulant. This study reports on the types of coagulant modification of CP, coagulants characterization of CP for each modification, coagulants performance of CP under various conditions, and various applications of CP coagulant for wastewater treatment. This literature study takes references from 51 articles from the period 2011-2022. We mapped each article used and visualized it using the VOS viewer to find out the relationship between topics and absorption capacity in terms of article titles and keywords. From the results of a literature review study, CP is an attractive option and has the potential to be used as a natural coagulant or adsorbent to remove pollutants (such as dyes and turbidity) in wastewater treatment. The results of this study are expected to provide benefits and ideas for utilizing agricultural waste such as CP to become an economically efficient material.

It is known that palm oil is one of the top selling raw materials that are widely used in both food and non-food industries. It is also widely used as a feedstock for biofuel production. However, the palm oil industry produces a huge amount of effluent that normally contains undesirable contaminants and suspended solids (SS), with high chemical oxygen demand (COD) and biochemical oxygen demand (BOD) values. Hence, it is imperative to ensure the sustainable management of palm oil production and to prevent serious environmental pollution. Various techniques are available to treat palm oil mill effluent (POME). This review summarizes the compilation of articles published in the period of 2010 to 2020 that focused on the development of treatment techniques for POME. Academic databases including Scopus, ScienceDirect, Web of Science, and PubMed were used to search for related articles. This review discusses the performance and highlights the optimum operating conditions for each chemical treatment technique. This review is not only relevant to researchers who work on the advancement and innovation of remediation technologies for POME, but it is also significant for researchers who deal closely with environmental pollution, water resource management, environmental protection, and flora and fauna conservation.
