What kind of parameter is necessory to measure to say that recycled water is pure or not?
1: Fill a clean, clear glass with water from your recycled water.
2: Hold the glass up to the light and take a look at the water. Is it clear or cloudy? Can you see particles floating in the water or settling to the bottom of the glass? Anything other than clear liquid could be a sign of bacterial or particulate contamination.
3: Smell the water. Does it smell like rotten eggs, a swimming pool, nail polish remover, or anything else unpleasant? These odors could indicate the presence of high chlorine content, organic solvents, or naturally-occurring sulfur.

I think this relates to the goal of the used recycled water industrial, irrigation, domestic, etc.).
Based on the goals you might investigate on the parameters that identify the pure water (TSS, turbidity, pH, odor).
Please see following link
Mainly PH,Turbidity, odour,TDS, & Heavy metals etc

That depends on the applications, for example for gardening, its different standard, if for Drinking or industrial application its is different standards. First identify the application then we talk on the purity.
Actually we purified textile dye treated water from our nanoaprticles. Our dye was fully acidic and after purification we got pH:7. Now the question is how to say that i removed everything from the dye water?
I can do COD, BOD and Turbidity but anything else to say that this is highly purified water.
I agree with Dr.Saravanan, it depends on application. But atleast for floor cleaning purpose we can use this water.
You can do experiments to find out hardness, COD, DO of water for both the samples before purification and afterwards. May give a clue regarding the purified water's level of usability.
In my opinion, the parameter that most important in telling that the water can be used is the percentage removal of preferred dyes in mixtures. It can be humic acid or any others ammonium-nitrate compounds in water. Commonly, this is the main problem in various of wastewater treatment application.
