VANCOUVER, BC--(Marketwire - April 14, 2009) - Purio (
Leonard Girard, Chief Science Officer with Purio, explains just how challenging this septic-tank source of wastewater was. "An October 2008 demonstration of the Purio technology impressed the world with its processed residential wastewater we pumped directly out of a residential sewer manhole. In terms of the Biological Oxygen Demand (BOD) loading, the recent septic tank sample reported on here is over 3.5 times more concentrated than the sewer manhole sample; similarly the Chemical Oxygen Demand (COD) of the septic tank sample was about 3.4 times more concentrated. Total Suspended Solids in the septic tank sample was over 48 times higher than that in the sewer manhole. The Bacteria load of 14 million Total Coliform Bacteria per 100 mL (about a third of a cup) showed the septic sample highly contaminated with pathogens. In our ever-growing quest for excellence, we decided to rise to the challenge of processing the septic tank sample so that we may learn more about the Purio technology's capabilities under the most demanding situations. I must say that the impressive Lab Test results of this exercise not only give us a sense of reward, but they also encourage us to strive even higher."
Girard continues, "Our unit was set to process about 2650 USG (10,000 liters) per day and is equipped with on-board testing monitors which display water quality parameters in real-time along the treatment train during operation. Our monitors showed that the water produced was clear, bacteria-free and sanitary. Purio's plant operators are no strangers to sipping the product water, and on this occasion, several on-lookers joined the 'taster's club' and drank the crystal clear water."
Earl Switenky, Purio Chairman, says, "The Purio Technology has proven an even higher level of capability in managing the world's water crisis, and we are pleased to have been observed in this demonstration by local and international parties representing both commercial and humanitarian interests."
In layman terms the interpretation of the treatment results are as follows: pH refers to the alkalinity (higher pH) or acidity (lower pH) of water, a pH of 7 is considered neutral; the closer the output water is to 7 the less detrimental effect it has on the receiving waters to which it is released. Turbidity refers to the cloudiness of water caused by both dissolved and suspended particles. At 150 NTUs the water is very cloudy and at the 0.4 NTU level it is as clear as tapwater. Suspended Solids refers to the amount of material that is mixed in the water but not dissolved. It causes cloudiness and is related to the turbidity. Biological Oxygen Demand refers to the amount of oxygen that the wastewater would consume if it were released into a pond or stream and the organic compounds contained in it were allowed to decompose there. High numbers mean high oxygen consumption that would kill fish and other aquatic animal life forms. Chemical Oxygen Demand refers to the same phenomenon but is specific to inorganic compounds that consume oxygen when they decompose. Nitrogen and Phosphorus are nutrients which may cause algae blooms that upset the natural balance of a marine biosystem to the detriment of wildlife. E. coli and fecal coliforms are bacteria which cause serious illness or death to humans who ingest them. Most open water discharge standards do not require total sterility, however the Purio system is designed to strive for absolute sterility in order to maximize the safety of our discharge water to animal life and humans.
The lab tested some 56 organic, inorganic and bacteriological analytes and the table below summarizes some of the most critical ones, again proving the powerful effectiveness of the Purio System.
