The influence of nutrients in wastewater from dairy lagoons on the survival of Escherichia coli O157:H7 was monitored. Initially, the survival of E. coli O157:H7 in wastewater from which the competing native organisms had been removed by filter sterilization or autoclaving was compared with that in wastewater from which competing organisms had not been removed. Numbers of E. coli O157:H7 or E. ...

Water resources are of critical importance to both natural ecosystem and human developments. Increasing environmental pollution from industrial wastewater particularly in developing countries is of major concern. Heavy metal contamination exists in aqueous waste streams of many industries, such as metal plating facilities, mining operations, tanneries, etc. Some metals associated with these act...

A line source sprinkler was used to irrigate corn (Zen ?nays L.) plots with potato (Soianum tuberosum L.)-processing wastewater in 1979, 1980, and 1981. Nitrogen applications ranged from about 4 to 600 kg/ha. Corn yields were measured for each row, the grain and stalks were analyzed for total N, and N uptake was calculated. The plots were split by years, one-third of the area was fertilized wit...

Rare earth elements (REEs) including Scandium (Sc) are critical raw materials which greatly needed in the advancement of many modern technologies. Due to problems associated with primary extraction mining ores, procurement Sc and REEs from secondary resources currently explored adopting principle sustainability circular economy. Herein, for first time, Electrodialysis (ED) technology based on e...

In this study, twelve Mallards living in an artificial wastewater wetland were exposed to treated wastewater containing 1 x 104 x 10 enterococci 100 ml for a period of 55 days. Faecal samples were collected before, during and after exposure and analysed for Enterococcus spp. The isolates were phenotyped using the PhenePlate system. 270 Enterococcus spp. of Mallard origin were analysed, together...

Recently, phosphorus (P) has become a material that is the focus of many countries, including EU, due to its scarcity. EU countries significantly depend on P export/import lack extraction and deposits. In this paper, an economic analysis management in Slovakia as source for responsible sustainable exploitation reuse presented based available sources, whether traditional (P rock mining), recover...

In Japan, the coverage rate of domestic wastewater treatment among the population was 82.4% at the end of FY 2006, but the coverage rate of domestic wastewater treatment in areas with a population of 50,000 or less remains low (about 65%). In addition, because a smallscale treatment system requiring low construction and maintenance costs is sought because of municipalities’ financial difficulti...
