  • Enzyme Activities and Chemical Changes in Wet Olive Cake after Treatment with Pleurotus ostreatus or Eisenia fetida

    Abstract  A laboratory experiment was conducted to evaluate the enzyme activities and chemical changes recorded in a recalcitrant phenolic-rich waste after treatment with Pleurotus ostreatus or Eisenia fetida. The waste used was wet olive cake (alperujo in Spanish), a waste produced in huge amounts by the olive oil industry. Both P. ostreatus and E. fetida were very effective in removing ...


  • Wet electrostatic precipitators: A preferred technology for emission control

    The basic science behind electrostatic precipitators is as familiar and as simple as static cling. But today, this elemental force has been harnessed to a technology that is helping to remove millions of tons of toxic chemicals from our atmosphere; saving billions of dollars annually in pollution-related physical damage; and averting costly impacts on health and mortality rates for millions of ...

  • Dry/Wet Scrubbers for Clean Air Compliance

    Air-scrubbing venturis and towers may be the answer to clean air compliance for small- to medium-sized companies. Forthcoming requirements of the Clean Air Act Amendments of 1990 will inventory many more specific chemicals considered hazardous. From acetaldehyde to xylenes, the list regulated under the air taxies program includes 189 hazardous air pollutants (HAPs). That number may ...

  • Process auditing and performance improvement in a mixed wastewater–aqueous waste treatment plant

    The wastewater treatment process is based on complex chemical, physical and biological mechanisms that are closely interconnected. The efficiency of the system (which depends on compliance with national regulations on wastewater quality) can be achieved through the use of tools such as monitoring, that is the detection of parameters that allow the continuous interpretation of the current ...

  • Waste Disposal

    Introduction The final step in the waste management process is waste disposal, the permanent isolation of waste. Some wastes can be managed and disposed safely with existing facilities and proven methods. Other Department of Energy (DOE) wastes require more complex disposal facilities. DOE has conducted extensive research into alternative waste disposal methods and has concluded that deep ...

  • Sewage Pump - Klargester is the market leader for small and medium-sized domestic treatment plant and waste water treatment systems in the UK

    There are a variety of solutions on the market for properties in the UK that are unable to connect to the main sewer by gravity. However, UK building regulations dictate that pumping stations must be used whenever possible. As a result, pumping stations are the most commonly specified solutions for off-mains developments, ahead of sewage treatment plants, such as the Biodisc, and septic tanks. ...

  • Improved wet weather wastewater influent modelling at Viikinmäki WWTP by on-line weather radar information

    Municipal wastewater treatment plant (WWTP) influent is typically dependent on diurnal variation of urban production of liquid waste, infiltration of stormwater runoff and groundwater infiltration. During wet weather conditions the infiltration phenomenon typically increases the risk of overflows in the sewer system as well as the risk of having to bypass the WWTP. Combined sewer infrastructure ...

  • The biological basis of wastewater treatment

    Introduction This booklet was written to fulfil the need for a simple explanation of the biological processes that underpin wastewater treatment. It attempts to show how the bacteria involved deal with the organic carbon in the sewage. Remarkably, there are just 3 major processes involved, and these mirror exactly the 3 major processes at work in the plant viz: biodegradation, oxygen ...
