Hey Kevin……Enjoyed our recent telephone conversation………Want to speak with you more about filtration speed etc……As mentioned, we are committed to higher filtration volumes as we increase our gpm delivery to the concrete, 20 gpm being our goal, down at 4,000 psi and back to our main tanks at about 15 to 18 gpm…….You have thoughts on this as you described in our conversation, let me know……. So that we might become familiar with your Oil-up product for use in our garage cleaning and service station cleaning work, I have made two orders…….One just a 32 oz size, the other, your package, which includes your metering spray bottle combo…….. Very unique, I came across this after my first order……Looks to be a real boon for those not destined for mixing in different proportions…….Look forward to trying these products out, and once done in a variety of situations, I will call you to discuss my successes……. …….PS…….Good book, very good mission, I applaud you efforts in all this, surely not enough at the working level that are doing it……We too would like to be as green as we can be and still get the job done…… We all know that our work cannot be properly done with doses of very green but largely ineffective solutions, so a balance needs to be struck in all this……..Bottom line is, no matter what we lay down, and how green it is, whatever it is, it is toxic once it hits the oil lanes……. This is academic……….What is not, and needs the utmost of attention, is the complete and super fast recovery, filtration and recycle issue………This be solved, all else easily falls into line, the disposal problem into our storm drain system rendered moot………. When the big job cleaners solve this problem to satisfaction, the smaller, more affordable recycle systems and procedures will naturally be developed and will filter down to the smaller contractors, thus creating more of them to be out there on the parking lots and gas stations, and even the neighborhood driveways with upgraded and capable recycling systems……. Like I said, look forward to speaking with you much more about this……I am especially intrigued with you notion of chemical emulsification, though not a new concept at all, a grass roots, simplified, and very affordable solution should be possible, looks like you are onto this notion, wish you all the luck in this………. Talk soon……….All the Best!!......Joe Grippi Advanced Pressure Cleaning Solutions LLC……Citronal Company Inc………South Florida
