Thank you for all your insightful comments. The Jar tests are very well-known because it is always used by poly suppliers to test various Poly brands or to get the proper dosage at commissioning stage. Normally the dosing of poly, example 4kgPoly/TonDS would be established with tests and this would be inserted in the control philosophy to give a certain Poly dose per hour. This Poly dose is related to Solids Load as you know.

Above and beyond the jar tests, Studies have started here in SA focusing on Sludge Rheology to further decrease or Optimize Poly usage. Technology has also been marketed here in South Africa based on this Rheology concept

As many said, various parameters influence the behaviour of sludge which I agree on.

But as sludge enters the dewatering section on its way to the dewatering device, it's viscosity is determined by a measuring device. The whole idea is to relate sludge viscosity to Poly dose.

I wanted to know whether someone has tested this theory and was it any fruitful with respect to actually minimizing poly consumption.
