Mix the Polymer and Sludge: At the talk, measure 200mls of sludge in one of the premarked 250ml mixing beakers. Then draw the polymer in the syringe or pipette (our sludge took 11mls - there is 5mg per ml of polymer - for a dose of 275mg/l) and start pouring the sludge in the other beaker. As you pour, add the polymer as in the picture to the left.
