On a hot summer days, there's nothing that hits the spot quite like some refreshing sharbat, cool beverages. Sharbat is a very common drink during our family gathering. Seeds have a lot of health benefits. They reduce food cravings, reduce blood pressure and are high in omega-35, when they are socked in water, they form a gel that is known to hydrate. Adsorption of any Toxic drug or chemical used active charcoal to treatment these cases.Industrial waste water may contain some toxic metals such into the environment in quantities that pose risk to human health. The aim of this study was to remove the metal ions from aqueous solution.The effect of various parameters such as pH, contact time, temperature, initial concentration and adsorbent a dose. The present work was aimed to develop some potential adsorption media for removal of Co(II), Ni (II), Cu(II), Zn(II), Cd(II), and Pb(II) from water. Basil seeds was synthesized for the removal of Co(II), Ni (II), Cu(II), Zn(II), Cd(II), and Pb(II) from water. The adsorption media were characterized by chemical analysis, specific surface area analysis FITR, AAS, SEM etc.
The project was planned to produce max. protease from Whey by Rhizopus arrhizus at pH 4 and 37C temperature. Growth media employed to culture R. arrhizus for the production of enzyme were developed and fermentation conditions was optimized through various trials. Substrate water ratio, different nitrogen sources and cont. of nitrogen source were optimized. The fermented materials were harvested after 72 hours. These were filtered and centrifuged at 10,000 rpm at -10C. The filtrates were subjected to enzyme assay. Absorbance of the enzyme sample was determined at 660 nm on spectrophotometer. The enzyme activity was calculated and the results were analyzed statistically by using ANOVA under CRD and by taking MSE from ANOVA, DMR test w sap-lied to compare the treatment means. It was observed that 90% Whey and 2.5% cotton seed meal enhanced the production of protease by R. arrhizus. Max. enzyme activity was observed (149.26 IU/ml/min) in flask level at pH 4 and 37C temperature. These optimized conditions of growth media was again used in Air-Lift fermenter and determined the activity (169.78 IU/ml/min) that is greater than flask level. This is due to temperature in Air-lift fermenter.
Colloids refer to particles or macromolecules with at least one dimension of 1nm~1µm. A wide range of environmental particles fall within this category including microorganisms, nanoparticles, and mineral precipitates. Understanding colloid fate and transport in porous medium not only permits more effective protection of water supplies, but also allows for the development of more effective pollutant remediation strategies. Organic matter (OM) complicates colloid behaviour. To date the influence of OM on colloid mobility in porous media has been largely qualitative. This book presents research leading to the development of multiple-pulse column techniques that may be integrated with mathematical models to quantify the effects of OM on particulate colloid attenuation in saturated porous medium. Research has investigated how two groups of environmental organic compounds, humic acids and proteins, influence particulate colloid attenuation by saturated sand. Study findings may shed light on complex colloidal behaviour in organic matter impacted environment and be useful to professionals in contaminant hydrogeology, environmental remediation, and wastewater treatment.
Paper once used is often discarded as waste. The word waste refers to something that is no longer serving a purpose , something without value . The amount of post consumer paper-a major solid waste - is gradually increasing and its treatment and disposal has become a major social and environmental problem. Proper processing and recycling of waste can greatly reduce environmental pollution. Recycling is environmentally favorable for a variety of reasons. First, it conserves material resources and second, it conserves fuel. Resources saved per ton of paper recycling are 17 trees, 275 pounds of sulpher, 350 lbs of limestone, 900 lbs of steam, 60,000 gal of water, 225 kwh and 3.3 cubic yards of land fill space. So, recycling of waste paper becomes an absolute necessity not only to reduce scarcity of raw materials but also to curtail environmental pollution. Micro study to repulp, recycle and recover paper from post consumer paper by installing a paper plant had proved successful. An awareness generation effort was also undertaken to induct the knowledge through method demonstration and print media. The book delineates the procedure and satisfaction of objectives.
The limitations of conventional wastewater treatment technologies demand advanced research methods to tackle complex wastewater treatment. Chemical treatment of wastewaters containing biocidal or nonbiodegradable components is part of a long-term strategy to improve the quality of drinking water resources by eliminating toxic materials of anthropogenic origin before releasing the used water into natural cycles. An improvement in oxidative degradation procedures for organic compounds in aquatic media has been achieved recently in applying catalytic and photochemical methods. Such methods include processes which generated the hydroxyl radical in this category, namely ozone at high pH values, hydrogen peroxide with UV radiation and ozone or hydrogen peroxide with other hydroxyl radical initiators such as metals and metal oxides. Use of UV radiation for wastewater treatment was the initial and remains the most promising large long term market for the technology.
Water pollution is an exacerbated problem in many parts of the world as a result of limited water resources to satisfy the increasing agricultural, population and industry demand for water and due to the raise of polluted amounts posed to these water resources. Among these famous and important pollutants lagging from various types of industries are Dyes. Besides non aesthetic appearance, the dye wastes may be toxic to human and environment and due to non-easily biodegradable it remains for long time in water. Currently, there are several methods to treat polluted water with dyes but each method has some restrictions deal with high cost and accumulated large amounts of sludge. On other hand, there are many agricultural wastes which form clumping another environmental problem like rice husk. This book introduces a new conception to treat and utilize all these problems simultaneously where has been used rice husk as a low cost media for adsorbing dye from water and rid of treated husk in an economic, effective and eco-friendly methods after end of the treatment process. This book is useful for chemical, civil and environmental engineers and anyone interested in benefit from wastes.
In this work, the experimental characterization of gas diffusion material for PEM fuel cells is carried out. Properties such as porosity, capillary pressure curves, absolute permeability, and relative permeability were obtained for carbon paper Toray-090. Experimental fixtures and procedures used to characterize the porous material are presented. The effects of PTFE treatment (wet-proofing) and compression on the porous media properties were assessed. After characterizing the porous media material, two computational models of the air-cathode of a PEM fuel cell were developed using the gas diffusion media properties obtained. The hypothesis presented in this work is that cell performance can be accurately predicted using actual water transport characteristics of the GDL material instead of empirical correlations for well-sorted sands as reported by many authors.
