Using algae as a feedstock for biodiesel has been considered for a number of years, but it has always had limitations, due mainly to the production methods used to grow and harvest the algae. In this project, we propose a novel attached growth method to produce the algae while recycling dairy farm wastewater using the microalga Chlorella sp. The first part of the work provided a feasibility stu...

A short term solution for the treatment of dairy waste water is discussed. Discharge rate'is 500 m3lday with a high organic load (2,750 Kg CODlday). Low capital investment (US $ 330,000) and operational (US$ 0.55lm3) costs were required which ought to be competitive with current market prices but within the official environmental norms imposed by the national agency SEDESOL. The problem was sol...

Eighteen wastewater treatment systems were operated for one year to investigate phosphorus (P) removal. Systems paired co-treatment reactors containing iron or calcium drinking water treatment residuals with vertical-flow constructed wetland mesocosms planted with Schoenoplectus tabernaemontani (K.C. Gmel.) Palla. For secondary municipal wastewater, soluble reactive P (SRP) concentrations were ...

background: hospitals generate relatively large quantities of wastewater that may contain various potentially hazardous ma­terials; therefore the proper management of hospital wastewater is essential. methods:   in this cross-sectional study, the quality and quantity of wastewater in the hospitals of tehran university of medi­cal sciences (tums), tehran, iran, were studied and the suitable meth...

This research is to develop an improved technology in a wastewater treatment facility containing fermented buttermilk under operate of dairy product factory. Wastewater with high concentrations difficult treat. Through new Enzyme Biofilm Method(EBM), we made improvements and demonstrated appropriate operation. After two tests, the improvement final stage, despite accepting all waste, has kept d...

the effect of hydraulic retention time in a range from 1.0-5.5 days was evaluated in a laboratoryscaleanaerobic fixed bed reactor packed with a hybrid material composed of tire rubber and zeolite. underthese conditions, cod removal efficiencies varied from 28.3% to 82.1%, respectively. over the more than 6months of operation, no clogging was observed. the results obtained demonstrated that this...

One of the burning problems of our industrial society is the high consumption of water and the high demand for clean drinking water. Numerous approaches have been taken to reduce water consumption, but in the long run it seems only possible to recycle wastewater into high quality water. In this study, an attempt was made to compare the efficiency of aquatic macrophytes like Typha sp., Eichhorni...

Taguchi L9 orthogonal array was implemented to select optimum values of process parameters and to attain the maximum removal of pollutants and power generation from dairy industry wastewater using double chambered salt bridge microbial fuel cell. The maximum chemical oxygen demand reduction, current, voltage, power, current density and power density in double chambered salt bridge microbial fue...

Dairy factory wastewaters are increasingly being considered a valuable resource. However, these waters may also contain contaminants, natural or artificial, that may adversely affect the land to which they are applied. This review investigates dairy wastewaters, factors affecting their composition, some probable effects on land and compounds that may be used to trace the migration of pollutants...
