M f " E <br />Nancy Clay, <br />4/26/19 <br />Thanks for the opportunity Thursday to trial our Solenis polymer on the South Bend dewatering application. We <br />did demonstrate a significantly reduced usage for the plant using our product, 85965. <br />The BFPs were started with the competitor's polymer and set points were recorded after running for two hours. <br />In the meantime, our product 859 BS was loaded into the polymer hopper and batches with our product were <br />made -down. Our product had to be dialed down to a lower dosage for the BFPs to maintain optimal drainage <br />and operation. Resulting cake solids were also dryer than the few days prior. See the set points below. <br />�........... ............_.. <br />House Polymer (Polydyne)._.._ <br />_�.........._, <br />- Dosage Setpoint <br />Press # <br />_ ....... ............ <br />Lbs/T <br />......_.........-.-..._...7.......... �....� <br />Sludge GPM <br />Polymer GPM <br />� �.... _ ...2.8 _.......... <br />_. ....................................... .................. <br />77 <br />.........._.......................... ...... ..... <br />2 <br />7.4 <br />73 <br />2.5 <br />3 <br />7.4 <br />76 <br />www�ww77..._.._.. <br />2.6 <br />4 <br />7.4 <br />2.8 <br />859 BS (Solenis) <br />Dosage Setpoint <br />Sludge <br />Polymer <br />Press # <br />Lbs/T <br />GPM <br />GPM <br />1 <br />5.5 <br />78 <br />2.0 <br />2 <br />4.5 <br />71 <br />1.7 <br />3 <br />5.2 <br />77 <br />1.9 <br />4 <br />5.2 <br />78 <br />2.0 <br />Dosages were based on a basis of pounds of polymer required per dry ton of sludge.

Let us know if you have any questions or if we can further demonstrate the Solenis product <br />performance. <br />Thanks, <br />Andrew Rossetti <br />Authorized Solenis Agent <br />(920)634-9201 <br />KdM,E,SL C]jL ,fl ,:V Er V fl �rr¢F n. .mime _ ,.;.., qrn -- P `Y20 .3� 9-9783 � F 932'G�� 3 ��y..9785 <br />€ If Yy Inc�rtr: ��a'3::4� G��iW1JY r,y.7 Irp�„ V"�u-�y ��'401 y�a3'�rp �rr�uu+r �i�ti�wrr r�r r,, <br />
