A Cd and Pd issue [slurry - environment - agricultural - Selco]

Hi there;
 I'm considering the use of a polymer based technology
(http://www.selco.net) in order to reduce the amount of N from the
pig's slurry (finishing swine feed with dry feeding) of my barn.

The process ends with two separate fractions--liquid and solid.

That solid fraction include:

Solid fraction 20% (200 kg)

C              21,7         mg/Kg 5.5   651 mg 


* DEPENDING ON THE PIG SLURRY CHARACTERISTICS, THE POLYMER IN THE TOM
WILL REPRESENT 200 TO 400 g OF THE 17.64 KG.


The same table can be best viewed at their official site at:
http://www.selco.net/ing/fracso.htm (RECOMMENDED).

I think that from the above table Cd and Pd are only ones that can be
hazardous to the soil or the plants involved. So are the above amounts
of Cadmium and Palladium risky for some reason or another?

Are the amounts of Cd and Pd increasing between each slurry spreading
work?

Really the polymer technology is dependable, environmentaly friendly
and economically cheap?

Many thanks.

P.S.
