Phytoremediation of Textile Industry Effluent using Aquatic Macrophytes
Introduction Pollution can be defined in several ways. Water pollution occurs when energy and other materials are released into water. It includes all of the waste materials that cannot be naturally broken down by water. In other words, anything that is added to the water, above and beyond its capacity to break it down, is pollution. In certain circumstances pollution can be caused by nature it...
متن کاملAdsorption of Ammonium Ion from Anaerobic Digester Effluent Using Magnetically Modified Zeolite
Adsorption of ammonia from anaerobic digester effluent by magnetically modified zeolite (MMZ) has been investigated using a batch technique and comparison of adsorption isotherm equations. Adsorption isotherm models were utilized to describe the equilibrium isotherms and the isotherm constants were calculated. The sorption of ammonia follows Langmuir, Freundlich and Dubinin-Radushkevich (D-R) m...
متن کاملAquatic arsenic: phytoremediation using floating macrophytes.
Phytoremediation, a plant based green technology, has received increasing attention after the discovery of hyperaccumulating plants which are able to accumulate, translocate, and concentrate high amount of certain toxic elements in their above-ground/harvestable parts. Phytoremediation includes several processes namely, phytoextraction, phytodegradation, rhizofiltration, phytostabilization and ...
متن کاملComparison of Air Emissions from Raw Liquid Pig Manure and Biogas Digester Effluent Storages
Biogas digesters are commonly used in livestock farming in China. The digestion process converts large amounts of raw liquid manure (RLM) to biogas digester effluent (BDE). The BDE is then stored on the farm for some time before land application as crop or orchard nutrients. Storage of RLM or BDE is associated with gas emissions, although little information is available concerning comparison of...
متن کاملRecovery of nitrogen and phosphorous as struvite from swine waste biogas digester effluent.
OBJECTIVE To investigate the feasibility of nitrogen and phosphorus recovery from swine waste biogas digester effluent and the effects of pH and NH4+: Mg2+: PO4(3-) molar ratio on its precipitation. METHODS Precipitation experiments with swine waste biogas digester effluent were conducted at pH 7.5, 8.0, 8.5, and 9.0 together with NH4+: Mg2+: PO4(3-) molar ratios 1: 0.2: 0.08, 1: 1: 1, and 1:...
