Chemical precipitation approach to the removal of heavy metals from wastewater for discharge into sanitary sewerage
Abstract: NaOH, Ca(OH)2 and Na2CO3 were used as the precipitants in this study. The reaction time was set at 45 min, temperature at 50º C, pH at 9 for the hydroxides and 10 for the carbonate. Heavy metal ions precipitated includes; Pb2+, Cu2+, Mn2+, Zn2+ and Fe3+. NaOH exhibited highest precipitation for Cu2+ (99.2 %) and least for Zn2+ (75.2 %), Ca(OH)2 exhibited highest precipitation for Cu2+ (100 %) and least …

Surface-Driven Capillary Flow of Dyed Water in the Fabricated Microfluidic Devices for the Applications in Water Purification
Abstract: In this work, two SU-8 based glass microfluidic devices are fabricated by the maskless lithography and indirect bonding technique. Dyed water (80% dye, 20% water) is chosen as the working liquid to study the recorded surface-driven capillary flow in fabricated microfluidic devices. CMOS camera is used to capture the surface-driven capillary flow producing two individually recorded audio-video-interleave-files (as FileName.avi). This work may be useful in water purification using the SU-8 …

REMOVAL OF AMMONIA FROM DISTILLERY WASTE-WATER BY ION EXCHANGE
Abstract: This paper evaluates the removal of ammonium ions from wastewater and its subsequent treatment. The project is based upon a case study of a local distillery facing a problem of odor and wastewater disposal management because of the presence of high concentrations of ammonia, for which ion exchange principal for treatment was employed. Ion exchange has the ability to handle shock loadings and the treated water can be recycled again …

A Review on Advancements and Challenges of Catalytic and Non-Catalytic Waste Water Treatment Processes
Abstract: AbstractClean drinking water is a basic amenity to be ensured for all. As water resources are becoming increasingly scarce due to the rising imbalance between freshwater availability and consumption and many of the water resources are polluted by anthropogenic sources such as industrial, agricultural waste and household, therefore, treatment of wastewater remains a critical need before leaving it to natural water streams. Traditional wastewater treatment processes include filtration, adsorption, activated …

APPLICATION OF MICROBIAL TYROSINASE ENZYME FOR INDUSTRY EFFLUENT TREATMENT CONTAINING PHENOL
Abstract: Phenolic compounds are the major pollutants found in the wastewater. Mostly phenolic compounds are derived from several industrial activities like leather, steel and iron manufacturing, petrol refining and also from mining industries (U.S.EPA, 1980). They are found highly toxic and corroding in nature. They are very harmful for living beings as they cause skin disease, respiratory and gastrointestinal ulcer, hematological changes, kidney and nervous system disorder.Traditional treatments like chemical oxidation …
