“…The common event of the seasonal algae blooms in the surface drinking water sources like lakes and reservoirs due to the changes in nutrient loads and water temperature incur a severe challenge to conventional processes of drinking water treatment 42,43 . Undesirable cyanobacteria bloom not only interferes with the treatment processes but also discharges large amounts of intracellular pollutant and odor compounds that intensively affect the quality of water supply 44–47 . The presence of cyanobacteria blooms in water treatment plants based filtration leading to several major challenges such as increased coagulant request, short filter runs, and extreme head loss development 44 .…”

The algae bloom phenomenon incurs a major challenge to conventional drinking water treatment processes due to the discharges of a large amount of intracellular pollutant and odor compounds in the water sources. Membrane processes have been considered as promising technologies to treatment of algal‐rich water due to complete algal cell rejection however, its application has been limited by membrane fouling. In this work, the high‐performance loose antifouling PES NF membranes were fabricated using diazonium‐induced grafting and applied for treating real algal effluent. The modified membranes exhibited complete algal dye removal and turbidity removal throughout the long‐term filtration. Also, the coupling and radically modified membranes can be able to removed COD by up to 90% and 88%, respectively, while a removal efficiency of 24% was observed for bare membrane. It is worth noting that, a relative smooth behavior in permeate flux by loose modified membranes during prolonged algal dye filtration, demonstrating exceptional anti‐fouling property of membranes. In addition, the fouled modified membranes were effectively recovered by water flushing. Both loose modified membranes exhibited excellent resistance in the strongly acidic environment. These high performance antifouling NF membranes affords an innovative methodology toward the treatment of algal‐rich water.

“…Small particles or components from various sources of wastewater can be rejected throughout these two processes. [ 134 ] Advantageously, low energy requirements, compact plan size, simplicity, and scalability are just a few of the benefits of these processes. The size of the particles was discovered to have a substantial impact on their filterability.…”

Microplastic pollution has adversely affected the aquatic ecosystem, living creatures, and human health. Several studies in Malaysia have provided baseline information on the existence of microplastics in surface water, ingestion by marine life and sediment. Also, humans are exposed to microplastic due to consumption of contaminated abiotic and biotic products, such as processed seafood. Nonetheless, knowledge is still scarce among Malaysian on the potential remediation and pollution management of microplastics, which poses a significant challenge to preserve a good environmental status. Green technologies also other alternative to mitigate the contamination of microplastics for sustainable future. Hence, this review aims to provide an overview of microplastic's occurrence, fate, and implications in Malaysia's aquatic environment. Detection of microplastics from the water surface, ingestion by aquatics, and sediment samples are highlighted. Available different treatment processes toward microplastic remediation are also discussed. Additionally, the potential challenges, current perspective for plastic management in Malaysia, as well as green strategies for reducing microplastic contamination are also put forward. The goal of this work is to improve the understanding of the seriousness of microplastic contamination in aquatic environments, thus encouraging key concerns that need to be investigated further.
