Abstract. Biodiesel production from waste such as wastewater sludge, palm oil mill effluent and dairy provide more sustainable approach greener energy. This paper analyzes the kinetic modelling for biodiesel scum via microwave heating transesterification. The results this study show that transesterification of is a first order which defines dependent on concentration one reactant linearly. acti...

Land application of farm dairy effluent (FDE) may lead to water contamination, by contaminants such as phosphorus (P) and E. coli. A new FDE treatment technology using poly-ferric sulphate (PFS) has been developed recycle wastewater in for washing the farmyard. physical drainage model study was conducted investigate effect treating with PFS on coli leaching through subsurface drains. Dissolved ...

Increasing worldwide milk manufacturing and dairy processing resulted in producing more effluents, thus effective management of wastewater is now the most important issue. This study used a new design pilot plant-scale hybrid anaerobic labyrinth-flow bioreactor (AL-FB) to increase efficiency biodegradation biogas productivity improve microflora performance. In addition, effluent recirculation w...

Five streams in catchments with pastoral dairy farming as the dominant land useweremonitored for periods of 7–16 years to detect changes in response to adoption of best management practices (BMPs). Stream water quality was degraded at the start with respect to N, P, suspended solids (SS) and E. coli concentrations, and was typical of catchments with intensive pastoral agriculture land use. Tren...

Pelareh Dairy Industry (PDI) is located in the west of Iran. The aim of the present study was to assess the quality and quantity of PDI wastewater and compare the results with the regulations. PDI has a wastewater treatment plant that consists of sewage collection system, screening system, equalization tank, clarification tank, anaerobic system for pretreatment, activated sludge processing, dis...

Objectives Effluents contain a diverse abundance of antibiotic resistance genes that augment the resistome of receiving aquatic environments. However, uncertainty remains regarding their temporal persistence, transcription and response to anthropogenic factors, such as antibiotic usage. We present a spatiotemporal study within a river catchment (River Cam, UK) that aims to determine the contrib...

Surface discharges of anthropogenic nutrients historically have been the focus of Florida’s waterquality regulations. Groundwater contributions to eutrophication of Florida’s surface waters are a more recent focus. Florida’s naturally oligotrophic springs, streams, and lakes are experiencing significant anthropogenic nutrient contamination resulting from groundwater discharges with elevated nit...
