Microalgae in Bioremediation of Waste water and Production of Bioproducts
Abstract: Domestic wastewater treatment and remediation is an exclusive practice due to substantial time and scheduling needed for fruitful management. Recent waste water treatment plants are extremely mechanical and costly to build and sustain. Maximum of the domestic waste water is considered feeble or average in strength with nitrogen levels between 20–40 mg/L and phosphorus levels between 4–8 mg/L[3]. These concentrations of nitrogen and phosphorus are unwanted as they can lead …

In Vitro Evaluation of Bioremediation Capacity of a Commercial Probiotic, Bacillus clausii, for Chromium (VI) and Lead (II) Toxicity
Abstract: Heavy metals cause disastrous effects on any living organisms. Probiotics have the ability to reduce metal toxicity. Commercial probiotics having bioremediation capacity can use these bacteria as an alternative to conventional remediation methods. The bioaccumulation of heavy metals including chromium (VI) (Cr [VI]) and lead (II) (Pb [II]) causes fatal toxicity in humans. Some naturally occurring bacterial species, such as Bacillus and Pseudomonas, contribute their role in bioremediation of these …

Development of Superabsorbent Polymers from Natural Sources
Abstract: Superabsorbent polymers (SAPs) are special materials that can absorb and hold a very large amount of water compared to their own weight. They are commonly used in products such as baby diapers, sanitary items, agriculture, and wastewater treatment. Most of the SAPs used today are made from petroleum-based chemicals. These materials do not easily break down in nature and may cause environmental pollution. Therefore, it is important to develop safer …

A Study on the Future of Industrial WastewaterTreatment Plant: Trends and Innovations
Abstract: Industrial wastewater treatment plants (IWWTPs) stand at the critical intersection of economic productivity and environmental sustainability. Unlike municipal sources, industrial effluent is characterized by extreme heterogeneity, containing highly variable concentrations of toxic heavy metals, recalcitrant organic compounds, suspended solids, and emerging contaminants. This complexity necessitates bespoke, multistage treatment trains, often combining physical, chemical, and advanced biological methods (e.g., membrane bioreactors, electrochemical oxidation, and anaerobic digestion). This analysis examines the contemporary …
