Optimization of nitrogen and phosphorus removal from meat processing wastewaters using microalgal biofilms
Background: The conventional activated sludge processes are not able to completely treat the nitrogen and phosphorus compounds of meat processing wastewaters. Microalgal biofilm, which has the advantages of easiness and inexpensiveness, can be applied as a post-treatment method. Methods: The optimal levels of micronutrients and N/P ratio were aimed in the cultivation of Scenedesmus quadricauda...
متن کاملRemoval of methylene blue from aqueous solutions using modified clay
Introduction: Discharging of industrial colored wastewaters especially into aqueous environments can cause adverse effects on aquatic life due to their toxic natures. In this study, montmorillonite modified by hexadecyltrimethyl ammonium bromide (HDTMA-Mt) was used for the adsorption of methylene blue (MB). Materials and Methods: The influence of surfactant loading rate, contact time, pH, adso...
متن کاملEfficiency of Microalgae Scenedesmus in the Removal of Nitrogen from Municipal Wastewaters
Background: Due to the high content of nitrogen in the municipal wastewaters, this study evaluated the efficiency of Scenedesmus as an important microalgae in the removal of nitrate from wastewaters and its application as an appropriate culture medium. As algae have high resistance to temperature and pH changes, they can absorb low concentrations of nutrients and need simple low-cost technolog...
متن کاملRemoval of Pharmaceutical Compounds from Hospital Wastewaters Using Nanomaterials: A Review
Over the past few years, residual pharmaceuticals (antibiotics, anticonvulsants, antipyretics drugs, hormones) have begun to be considered as emerging environmental pollutants due to their continuous input and persistence to aquatic ecosystem even at low concentrations. Therefore, the development of efficient, cost-effective, and stable methods and materials for the wastewaters treatment have g...
متن کاملNitrogen removal by a nitritation-anammox bioreactor at low temperature.
Currently, nitritation-anammox (anaerobic ammonium oxidation) bioreactors are designed to treat wastewaters with high ammonium concentrations at mesophilic temperatures (25 to 40°C). The implementation of this technology at ambient temperatures for nitrogen removal from municipal wastewater following carbon removal may lead to more-sustainable technology with energy and cost savings. However, t...
