In this study two wet microalgae cultures and one dried microalgae culture were co-digested in different proportions with sewage sludge in mesophilic and thermophilic conditions. The aim was to evaluate if the co-digestion could lead to an increased efficiency of methane production compared to digestion of sewage sludge alone. The results showed that co-digestion with both wet and dried microal...

An Industrial and Enterprise Greenhouse Gas Emission Data Analysis System, which meets with the need of those giant energy-consuming enterprises, has been set up through a series of studies about Greenhouse gas (GHG) verification method in industries such as cement, thermal power, cogeneration, transportation, sewage treatment etc. The analysis system consists of six modules: Organization struc...

nowadays, with population growth in urban areas, providing safe water and health is considered basic needs of human, alongside the various pollutants due to urban activities, agriculture and industrial areas on adjacent ranges into urban water resources around the environment is such that study necessary to prevent the pollution of water resources and identification of pollution sources shows. ...

the present study investigated no3- and br- contamination in groundwater of arak aquifer of markazi province. correlation and factor analysis were used to detect interrelation and sources of concentration of no3- and br- ions and others physicochemical variables. no correlation was observed between no3- and others contents, but positive correlation was identified between br- with other major va...

Mussels maintained in sea water heavily polluted with domestic raw sewage have been found to harbor human enteroviruses.

biogenerics production has been done in lots of advanced industrial countries since last decades and its legal aspects are adequately addressed. on the other hand, the need of our country to these drugs is inevitable and its production in recent years has begun without taking its legal aspects into account. we don’t have any legal system to regulate biogenerics production and commercialize them...

Nowadays, waste production is increased due to the growth of technology and excessive use of natural resources as well as production of new chemicals, among which the hazardous wastes are no exception of that stabilization and solidification method is one of the hazardous waste management methods through which the waste materials are stabilized and confined. High flexibility for various polluta...

Recycled wastewater has been identified as an alternative source of domestic water. This paper assesses whether the utilization recycled produced by industrial park in Batam Island could reduce freshwater extraction from primary source. The analysis is carried out probing record water usage and sewage treatment plant’s production for almost 2 years. wastewater’s quality limits its only gardenin...
