Claim 1
Independent Claim
249 words
A water treatment system comprising: an accumulation tank for receiving a soiled solution; a tank outlet valve for selectively allowing flow of said soiled solution from said accumulation tank to points downstream of said accumulation tank; a blend conduit leading from said outlet valve; a first means supplying a first oxidizing agent to said soiled solution downstream of said outlet valve and upstream of a first filter stage comprising a first filter means; a blend pump receiving said soiled solution with said first oxidizing agent, said blend pump promoting flow of said soiled solution through said system and for promoting uniform dispersal of said first oxidizing agent through the solution; a second filter stage downstream of said first filter stage and comprising a second filter means of a different type than said first filter means and having a finer filter media than said first filter means; a second means supplying a second oxidizing agent to said soiled solution just upstream of said second filter stage; a third filter stage downstream of said second filter stage and comprising a third filter means of a different type than said first and second filter means and having a finer filter media than said second filter means; a third means supplying a third oxidizing agent to said soiled solution upstream of said third filter stage; an ultraviolet light treatment means downstream of said third filter stage for producing a treated solution; and a treated solution accumulator downstream of said ultraviolet light treatment stage.
Claim 2
Dependent Claim
249 words
A water treatment system comprising: an accumulation tank for receiving a soiled solution; a tank outlet valve for selectively allowing flow of said soiled solution from said accumulation tank to points downstream of said accumulation tank; a blend conduit leading from said outlet valve; a first means supplying a first oxidizing agent to said soiled solution downstream of said outlet valve and upstream of a first filter stage comprising a first filter means; a blend pump receiving said soiled solution with said first oxidizing agent, said blend pump promoting flow of said soiled solution through said system and for promoting uniform dispersal of said first oxidizing agent through the solution; a second filter stage downstream of said first filter stage and comprising a second filter means of a different type than said first filter means and having a finer filter media than said first filter means; a second means supplying a second oxidizing agent to said soiled solution just upstream of said second filter stage; a third filter stage downstream of said second filter stage and comprising a third filter means of a different type than said first and second filter means and having a finer filter media than said second filter means; a third means supplying a third oxidizing agent to said soiled solution upstream of said third filter stage; an ultraviolet light treatment means downstream of said third filter stage for producing a treated solution; and a treated solution accumulator downstream of said ultraviolet light treatment stage.
Claim 3
Dependent Claim
26 words
The system of claim 1 wherein said first filter stage comprises a first rotary drum filter and said third filter stage comprises a micron pot filter.
Claim 4
Dependent Claim
15 words
The system of claim 1 wherein said second filter stage comprises a first vacuum filter.
Claim 5
Dependent Claim
23 words

Claim 7
Dependent Claim
42 words
The system of claim 1 further comprising: means for introducing a flocculating agent into said soiled solution upstream of said blend pump; and a conduit downstream of said blend pump for promoting uniform dispersal of said flocculating agent and for promoting flocculation.
Claim 8
Dependent Claim
32 words
The system of claim 1 further comprising a booster pump upstream of said third filter stage and wherein said third means for injecting oxidizing agent is just upstream of said booster pump.
Claim 9
Dependent Claim
22 words
The system of claim 4 further comprising a fourth means for injecting oxidizing agent between said first and second rotary drum filters.
Claim 10
Dependent Claim
22 words
The system of claim 1 wherein said third filter stage comprises a first fine stage comprising first and second micron pot filters.
Claim 11
Dependent Claim
20 words
The system of claim 1 comprising means for providing a backwashing fluid and means for backwashing the third filter means.
Claim 12
Dependent Claim
32 words
The system of claim 1 comprising means for heating treated solution downstream of said treated solution accumulator and means for using said treated and heated solution to backwash the third filter means.
Claim 13
Dependent Claim
21 words
The system of claim 10 comprising means for recycling the backwashing fluid after using for backwashing to the first filter stage.
Claim 14
Dependent Claim
33 words
The system of claim 1 wherein said third filter stage comprises first and second micron pot filters each having means for allowing for selective forward flow during filtration and backward flow during backwashing.
Claim 15
Dependent Claim
54 words
The system of claim 9 wherein said third filter stage further comprises a second fine stage comprising third and fourth micron pot filters downstream of said first and second micron pot filters and wherein said second fine stage comprises means for diverting flow from said first fine stage directly to said ultraviolet treatment means.
