ABSTRACT:
This invention relates to waste water treatment, more specifically this invention relates to transportable decontamination system for water which is pumped from manholes and equipment vaults. The separation of water and contaminants is accomplished by a five module system. The first module removes 98% of the solids from the waste stream by use of staggered baffles. Module two reclamates the free oil present in the liquid flow with an coalescing water oil separator. The third module removes solids still left in the stream which are greater than 20 microns by use of a size discriminating filter. The fourth and fifth modules are bonding tanks used to encapsulate hydrocarbons and heavy metals respectively. The sequence in which the contaminated flow enters each of the modules is essential to the effectiveness and efficiency of the filtration process.
