Description 

DESCRIPTION
- Nu-Well 220 dispersant polymer uses liquid dispersant chemistry specifically designed to remove mud and clay from the well environment.
- Successfully develops new wells without using phosphate
- Eliminates food source for bacteria (100 percent water-soluble, readily flushed from the well)
- Rehabilitates old wells plugged with clays, silts, and fines
- NSF approved for potable water well use


APPLICATION
In new well systems, use Nu-Well 220 dispersant polymer as you would phosphates for drilling mud breakdown and well development. For optimal removal of bentonite drilling fluids, separately pre-treat the well with 1,500 ppm chlorine to break down the polyacrylamide polymers that are included in most commercial bentonite products. Determine borehole volume, and apply Nu-Well 220 dispersant polymer at the rate of 1 gal. per 500 gal. of water. Vigorously agitate by mechanical means for several hours (approximately 1/2 hour per 20 ft. of intake). If left in the well overnight, agitate before pumping out.


In older well systems use, Nu-Well 220 dispersant polymer to remove fine sands, mud, and clays that have filled in the gravel pack and borehole. Use at a rate of 1 gal. per 300 gal. of water. Vigorously agitate (by mechanical means), allowing the solution to stand in the well overnight and repeat the agitation the next day, before pumping out.

Don't climb down into that well!
I'm an old lady so I wasn't going to climb down into my old 8 ft. stone lined(36" diameter)well to clean out the 9"-12" of clay/muck at the bottom. The well hadn't been cleaned for about 20 years and had lay unused for a little over a year so the clay/muck had compacted and was interfering with the intake pipe.

I put a 1 hp submersible sump pump into the well, lowered the water level to about 500 gal. and added 1 gal. of the very expensive (and worth every penny!) NuWell 220. I poked around in the clay/muck to be sure the dispersant solution permeated into the thick clay/muck layer at the bottom. I waited over night.

By the next day the sediment had become "fluffy" and I used my sump pump to shoot all the muck out of the bottom of the well. I have twice completely flushed the well and I'll do it once more to be sure.

My well is now clean down to its gravel bottom, the intake pipe is clear, AND NO ONE DIED!! I wouldn't have water without NuWell 220. Thank you people!
