  • Corrosion in wastewater systems: More than one bug

    The role of various bacteria in the destruction of concrete in wastewater systems has been recognized since 1945. Parker1 described the role of an acid producing bacterium that he called Thiobacillus concretivorous, which he had isolated from corroded concrete from a Melbourne, Australia sewage system. Th. concretivorous was described as a sulfate reducing bacterium (SRB) which converts hydrogen ...

  • What kind of waste carbon can I use in my nitrate removal system?

    Biological denitrification is the conversion of nitrate (NO3) into nitrogen gas (N2) and carbon dioxide (CO2) by a consortia of bacteria.   This process requires good control over the ratios of three elements- carbon (generally must be supplied externally), phosphorus (nearly always in Ag runoff),  and nitrogen (from the nitrate nutrients in the runoff).  Since the ...
