  • Maintenance for septic tanks

    Septic tanks are widely used for on site sewage treatment for domestic homes which are not connected to the sewer system. Little attention is given to the septic tank until there are problems such as smells or poor drainage or ponding on the surface. A little maintenance of the septic tank can be very helpful in maintaining performance of the septic tank. The outflow from a septic tank percolates ...

  • Effects of poly aluminum chloride dosing positions on the performance of a pilot scale anoxic/oxic-membrane bioreactor (A/O-MBR)

    The effects of poly aluminum chloride (PACl) dosing positions on the performance of a pilot scale anoxic/oxic membrane bioreactor were investigated. PACl dosage was optimized at 19.5 mg Al2O3/L by jar test. Nutrients removal efficiencies and sludge properties were systematically investigated during periods with no PACl dosing (phase I), with PACl dosing in oxic tank (phase II) and then ...

  • Comparing the performance of prescribed septic tanks to long, narrow, flooded designs

    About 30% of all sewage generated in North America passes through septic tanks, but there is a lack of study to improve these important treatment vessels, and there is no performance-based standard. A survey of existing literature shows that septic tank effluent quality is improved in tanks designed for quiet, laminar fluid-flow and minimum ‘dead space’ such as in longer, narrower tanks. A ...

  • Oil in Power Plant Wastewater

    The water is from the operations of a steam power plant located in the Bahamas. The water samples were taken from the Unit 31 (lower oil content) and Tank #3 (a higher oil content). The samples were tested and it was found through the jartesting procedures that the Floccin K was the best choice for floc size and water clarity. The Unit 31 was dosed at 0.5 gram in 1,000 ml and the Tank # 3 water ...

  • Bioavailability and bioaccumulation of sediment‐bound PCBs to carp

    The relative bioavailability of sediment‐bound polychlorinated biphenyls (PCB 138, 153 and 180) from a local contaminated site was examined using an in vivo carp model. Surface sediment from the PCB contaminated site and spiked canola oil containing equivalent masses of PCBs were respectively incorporated in the “sediment‐dosed diets” and “oil‐dosed diets” at 3 dose levels resulting in 6 ...

  • Toxicity of elevated partial pressures of carbon dioxide to invasive New Zealand mudsnails

    The authors tested the efficacy of elevated partial pressures of CO2 to kill invasive New Zealand mudsnails. The New Zealand mudsnails were exposed to 100‐kPa at three water temperatures, and the survival was modeled versus dose as cumulative °C‐h. We estimated an LD50 of 59.4°C‐h for adult and juvenile New Zealand mudsnails. The results suggest that CO2 may be an effective and inexpensive lethal ...

  • Give Your Denitrification Bugs a Sugar High

    ABSTRACTAn alternative substrate to methanol was sought for tertiary denitrification. High fructose corn syrup (HFCS) was identified as the most cost effective alternative, which would also be much safer to handle. This should also render HFCS subject to less legislation at all levels of government. A pilot scale test was conducted. The test confirmed that HFCS is a suitable substrate. A dose of ...

  • Spilled heavy grade heating oil case study

    Heavy fuel oil escaped from a storage tank and entered the drainage system of a large creamery. This material passed to the aerated balance tank which precedes an activated sludge system treating the factory waste waters. Alerted to the spillage the operators were able to shut off the flow to the activated sludge system but not before a significant quantity of oil had passed through. Bio-Systems ...
