Physical, Biological and Chemical Treatment of Distillery Spentwash: A Review
Molasses based alcohol distilleries in India are one of the most polluting industries; In addition, they are high consumers of raw water. Growing scarcity of high-quality freshwater as well as stringent regulatory standards is compelling these units to explore appropriate water management options. This report provides an overview of the water use and effluent treatment …. Read More
Investigation of Electrical Drop-Drop Coalescence of the Simulated Water Droplets Falling in Sunflower Oil
In many industries, dispersion of water droplets in oil or oil droplets in water is not desirable and they must be separated. Thus, Non-Uniform Electric field (NUE) is used as an ecological method for separating such a dispersed phase. In this paper, performance of water droplets in sunflower oil was investigated under NUE. Measurements were …. Read More
Production of Melissa Officinalis (Lemon Balm) Extracts Applying Multiple Methods and Investigation of its Encapsulation Using Chitosan
In the present study, Melissa officinalis (lemon balm) extract production was investigated using various extraction methods including maceration, soxhlet, ultrasound-assisted, enzyme-assisted and microwave-assisted extraction. Effectiveness of the employed methods was deliberated through determining the total phenolic content, antioxidant activity and extraction efficiency of solids content. Accordingly, Melissa officinalis extract with total phenolic content of 311.94 …. Read More
Fertilizer Absorption Efficiency δ15N -Labelled Applied To Maizecrop (Zea Mays) in Central Chile
Nitrogen stable isotopes (δ15N) help to understand the Nitrogen (N) uptake in different crop parts. This study investigates the contribution and distribution of N absorption within the different fractions/organs (leave, stem, root and grain) of the crop plant (Zea mays), and labelled N remaining into the soil (0–50cm).
Ecophysiologicals Responses of Olive Trees (Olea Europaea L.) Hybrid Varieties in Soil Amended with Olive Mill Waste Waters
This study aimed the using of olive mill wastewaters (OMW) in agriculture to reduce its ecological negative impact. The main objective is to study the effects of the application of OMW at a fixed dose (50 m3 ha-1) on the agronomic development…
Investigation on Kinetics and Equilibrium of the Adsorption of Ammonia Nitrogen on Activated Carbon Modified By Nitric Acid
The coconut activated carbon (AC) was modified by using nitric acid as the activator. Unmodified and modified AC samples were characterized in terms of structural, morphological, surface, and chemical properties. The oxygen functional groups of surface such as hydroxyl group and carboxyl group were obviously…
The Research of Artificial Radionuclides Speciation in Surface Water at the Semipalatinsk Test Site Territory
This research examined the speciation of artificial radionuclides in the surface waters at the Semipalatinsk test site territory. The speciation of 90Sr, 137Cs and 239+240Pu in the most polluted water bodies of the “Degelen”, “Experimental Field” and “Telkem” test sites are determined by cascade filtration…
Large Specific Surface Area Nitrogen-Doped Biochar Cathode: A Tactics for Recycling Nitrogen and Phosphorus Enriched Aquatic Plant
In this study, a nitrogen-doped biochar oxygen reduction reaction(ORR) cathode(Alternanthera philoxeroidescarbon) was produced by two kinds of molten salts (ZnCl2 and Mg5(OH)2(CO3)4) carbonization without extra nitrogen source, which had an excellent performance in Electro..
Improving Biogasfermentation of Sludge and Cosubstratesby Combining Acidification with Disintegration Systems
semi-scale acidification batch reactor (700 litres) was installed at the domestic wastewater treatment plant Hof (Germany) and feed with thickened sludge and treated with electroporation and hydrodynamic induced cavitationwith exposure times up to 6 hours. Inoculation from the large-scale sludge digester improved acidification significantly.Investigations were carried out…
The Origin of Submerged-Soil-Based Rice Cultivationwith an Emphasis on Archeological Evidences
Rice cultivation has long been considered to have originated from seeding of annual types of wild rice somewhere in subtropics, tropics or in the Yangtze River basin. That idea, however, contains a fatal weak point, when we consider the tremendous difficulty for primitive human to seed any cereal crop in the warm and humid climate, …. Read More
