The video shows the wastewater clarification process. It was taken with no preparation when some folks came from Sweden to see the system in operation. Some folks believe that boat wash wastewater can simply be transferred to barrels and left to settle out. Simple settling in barrels will remove most of the particulate but NOT the Toxic Metals.
Metals are in perfect equilibrium with the wastewater and will remain in solution forever or until the equilibrium is disrupted. That is what the VANISH process does – It disrupts the equilibrium and the toxic metals and particulate quickly fall to the bottom of the treatment tank.
