"lack of definitive information from purio showing that they have a viable product from a business perspective."
What's this then? I think it clearly states that the producst is "viable".
Independant Performance Evaluation Report Exceeded Expectations
At a cost of over $250,000 the performance of the PURIO technology was monitored and evaluated by Canadian Environmental Technology Advancement Corporation-West (CETAC-WEST). The comprehensive evaluation report is similar in most respects to USEPA or ISO 14023 protocol. Operational data from the plant, actually serving the wastewater treatment needs of a community of 120 homes was evaluated over a nine-month period. This report, summarized on Table 1 below, confirmed the unit’s ability, alone, to meet “enhanced primary” treatment objectives in terms of BOD (biological oxygen demand) and TSS (total suspended solids). It exceeded expectations by reaching “tertiary” standards in phosphorus removal. The plant was not designed to address nitrification or nitrogen removal so it did little, as expected, in either.
Coupled with accessory components, the train met the even higher “tertiary” treatment efficiency in terms of BOD and TSS and phosphorus concentrations.

Smaller-scale “Batch” unit developed and Sold
Its technology has been employed in a smaller scale “batch” version of the clarifier and is successfully operating on location. This unit produces clarified water for household use. The unit has now been serving a rural household in Canada for about three years with total success. The batch unit draws water from a lagoon (or dugout as it is sometimes called) that is overgrown by reeds, grasses and contains abundant wildlife. This raw water has a green color and a strong “wild” odor making it unfit for human use.
The water is drawn into the unit, clarified and stored in a cistern. The clarification process removes all color, and nearly all of the suspended solids to produce a clear, clean odorless product. No further treatment is required for its use in laundry, toilets and bath use. For drinking, this clarified water is then polished by means of a Reverse Osmosis system to produce high quality drinking water that is then passed through an Ultra-violet sanitizer to assure sterility.
The capacity of the batch clarifier unit is 1000 gallons (4000 liters) per day. The unit is fully automatic and requires only about $20.00 CDN per month in in-puts.
The product was able to out-compete regular filtration methods proposed by other companies and has proven its effectiveness over several years of trouble-free operation.
