SIMPLE START™ INTERNATIONAL MARKET

Initial Visit  Onsite Testing  System Survey Form  Treatability/Screening- ATP test

System Survey *CATER™ Mobile App will be available in Summer of 2015

System Survey: PAIN

System Survey: Analytical Onsite Testing

)System Survey: Process Flow Diagram (PFD) There is an area on the form to include a small sketch of the treatment schematic An alternative option is to scan a diagram of the facility to your sales representative for future reference and technical support (see example below)

System Survey: Return on Investment (ROI) The second page of the system survey has a focus on financial aspects and areas where records could be kept to help provide an ROI calculation

System Survey: Summary This is an essential “clipboard” document and should be conducted every time the facility is visited for record keeping purposes Helpful Hint: Attach cheat sheets to your clipboard See following slides Also allows you to determine if there is an opportunity to help the client

CATER™ Tool Kit Contains all the in-field real time tools necessary to assess an opportunity Combined individual test cost is under $10.00 site

ATP Testing Test in Progress The objective of this testing procedure is to determine the impact an influent wastewater sample has on Biotifx™ product Health/Toxicity is measured based on the amount of cellular (living ATP) present in the sample after treatment after 30 minutes of aeration in a standard (Biotifx™ only) vs. test (Biotifx™ and known volume of influent)

ATP Testing: Terminology Cellular ATP= Living cell mass Total ATP= Total cell mass Free ATP= Dead cell mass

ATP Testing: Basic Interpretation Of Results If “X” amount of sample is added to a Biotifx™ solution, is there an increase or decrease in cellular (living) ATP? If cellular ATP increases, the test passes fails If cellular ATP decreases, the test fails Note, this is in yellow as in caution, not red Note, this is in yellow as in caution, not red At this point, technical support becomes involved to determine what the limiting factor may be

ATP Testing: Interpretation of Results Record Total and Free ATP values for both the standard and the test sample and plot Note that cellular ATP (living amount) is not tested for directly, but calculated by subtracting free ATP value from Total ATP value There is a net increase in Cellular ATP so the screening test passed

ATP Testing: Clipboard Document

ATP Testing: Notes If the test does not pass after 30 minutes, repeat the procedure after 45 and after 60 minutes Occasionally more than 30 minutes is needed to see a response Always collect as much GS PATTON™ data as possible on the influent sample If the test fails, it may be due to low pH, toxicity, or lack of nutrients

ATP Testing: Failed Sample Results If the GS PATTON™ parameters are not known, take the influent sample back to the lab and determine if nutrients, pH, or alkalinity are limiting A failed test does not mean we can’t help them, it just means other changes may useful in addition to Biotifx™ Send a influent sample into MDG for a treatability test
