steve- once again I mention that the lead that is actually in the water is in solution i.e. the lead is in a molecular form that has attached to a H2O molecule. To have a minimum of lead that is below the regulated ppm, there cannot be any chunks,

We use an evaporator, so that we only have a sludge of flux residue and solder metal to dispose of via the hazmat handling service. We also route stencil washer waste water into it. We use a 30 gallon drum and have it hauled off maybe twice a year,

Before entering the cleaner, the board should reach almost temperature of first pre-wash module (are you using DI water washing machine?), if water cleaner, normally the temp of prewash spry is set from 45 C� to 55 C�. (or it could be 10�C higher, bu

If the batch cleaner is truly closed loop, then 100% of all of the process fluid (water) is captured, filtered (particulate, carbon, resin) and reused. This answer is based on a traditional closed-loop batch cleaning system with an integrated water

The specific answer depends on what your specific application includes. #1: What are you removing? (solder paste, adhesives) #2: What are you cleaning? (stencils, screens, misprints, pallets) #3: What type of machine are you using? (Spray-in
