  • Sure, We Have Lots of Bioreactor Solids… But How Many are Active?

     ABSTRACT Biological wastewater treatment processes harness the ability of microorganisms to break down and assimilate organic compounds that, if left untreated, cause detriment to the environment. Although this process occurs naturally, engineered systems are used to accelerate the process by optimizing bioreactor conditions to promote higher-than-typical biomass concentrations, thus ...

  • FRACKING: Freeing Energy Resources versus Polluting the Earth and Public Health with Radiation and Toxic Chemicals?

    Fracking demands the use of millions of gallons of water, precious drinking water, and sand infused with up to 1,000 different toxic chemicals to fracture the shale rock and release the trapped gas or oil.

  • Wastewater treatment down-time `not acceptable`

    Reliable 24/7 monitoring and control of a pharmaceutical company's wastewater facility is fundamentally important to the successful operation of the entire business. This is because failures or down-time in the wastewater treatment process would quickly result in waste stream back up. It follows therefore that monitoring equipment should be extremely reliable and this is why Shasun Pharma ...


  • Sustainable mining

    It's imperative that natural resource industries adopt a proactive (even aggressive) approach to the disposal and management of their wastes. Operators must challenge themselves to raise the bar in terms of environmental performance not only to meet the expectations of regulators today (and investors and the general public), but in the future, when requirements will no doubt be even more ...
