Treatment of Dairy Wastewater Using Constructed Wetland
Abstract: Naturally existing wetlands have been used for dumping various types of wastewaters and have been promised to dispose of these wastewaters. As a matter of fact, in some areas, natural wetlands still serve this purpose solely and are nothing more than dumping sites. However, extensive research suggested the use of Wetlands for Treatment purposes. Understanding the dynamics of the processes in natural wetlands leads to the use of those processes …

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 …

Treatment of Synthetic Dairy Waste in an Aerobic Bioreactor
Abstract: Bioreactors are used to treat industrial wastewater including petrochemical, pharmaceutical, agricultural, oil, dairy wastes, etc. Disposal of dairy wastes is of importance through the manufacture of milk products including cheese, butter, ice cream and processed milk. Most of the dairy industries use typical activated sludge method for their effluent treatment leading to a relatively high operation costs and problem with the disposal of large amounts of sludge. Aerobic processes are …

Nanocomposite Hydrogels for Water Purification
Abstract: DNA hydrogels have been demonstrated as versatile catalysts, potential adsorbents, sensors and immobilization carriers of bioactive molecules. They are a type of tenuous, semiflexible polymeric network that consists of precisely designed synthetic nucleotide strands as chemical or physical cross-linkers. Hydrogels have been widely studied due to their improved physicochemical properties and used as antibacterial platforms, wastewater pollutants, adsorbents and drug deliverers. Because of their biocompatibility and the ability to mix …
