  • Comparing the Realities of Elemental Chlorine vs. Sodium Hypochlorite

    Recently, we have seen a growing trend towards the use of a less reliable and more costly disinfection chemical, Sodium Hypochlorite. Much of this can be attributed to the fact that large companies making chemical metering pumps for other uses or other alternative disinfection devices as well as chemical suppliers who profit more by selling costly Sodium Hypochlorite have proliferated misleading ...


  • Supercritical carbon dioxide – from coffee to dry cleaning

    Sometimes I can’t start the day without my morning coffee, and I’m sure most adults would agree that consuming caffeine is a part of their daily routine.

  • Biodegradability of Alternative Oxygenates as a Sole Carbon Source or in the Presence of BTEX

    ABSTRACTThe biodegradability of alkylate compounds in serum bottles was investigated as a sole carbon source or in the presence BTEX. The biomass was acclimated with 2,3-dimethyl pentane (2,3- DMP), 2,4-dimethyl pentane (2,4-DMP) and 2,2,4-trimethyl pentane (2,2,4-TMP) in porous potreactors. The alkylates (2,3-DMP, 2,4-DMP, and 2,2,4-TMP) were completely biodegraded in all the sets of ...

  • 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 ...

  • Falling Through the Cracks

    An old environmental ghost has recently been reincarnated. Polychlorinated biphenyls (PCBs) provided plenty of scares in the 1970s, when studies found that the PCBs commonly used as insulators in electrical equipment (particularly transformers that leaked the substance into soil and water supplies), were not only carcinogenic, but also that PCB pollution tended to accumulate and become magnified ...

  • Carbon capture could be costly and risky

    There’s bad news for those who think that carbon dioxide can be removed from the atmosphere and stored deep in the Earth’s rocks. Even if carbon capture is possible, sequestration in the rocks is fraught because the gas can find multiple ways to escape, according to a report by a team from Penn State University, US, in the International Journal of Greenhouse Gas Control. Back in the ...
