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
pH, Temperature, Alkalinity, **ATP test
*Ammonia, *Phosphate, *Nitrate, *Nitrite, Temperature,
Dissolved Oxygen, ORP * If filtered before testing
** If only tested on initial visit or as desired
CATER™ Onsite Testing
Demonstration Of Tests
• MDG sales representative will demonstrate use of CATER field kit
• Videos are available for reference in your private log-in access at the MDG website
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• If cellular ATP decreases, the test fails
• 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: 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
Simple Start™ Reminder
Remember to have the following:
Facility Survey Form
Onsite Testing Kit
ATP Testing Kit (if needed)
Simple Start™ Proposal
Based on your site visit, a successful ATP test could justify a proposal and initiation of a project and purchase
