Hello Technetters,

For those of you out there using saponifiers to clean stencils/PCBs, how are you treating your waste
wash water? We're using a Zenon Environmental bioreactor/ultrafiltration system to treat our water
(Kyzen Aquanox 101 saponifier, Kester R244 solder paste) but we've had all kinds of problems keeping
the system stable. We're also facing a very costly ($ and space) upgrade as more cleaners are coming in.

Does anyone know of a source of treatment systems that can handle this waste? Any info, experiences,
recommendations, etc. would be greatly appreciated.
