CTMP Revision 0 2.2 Results of Superfloc Bench Tests Bench tests were also undertaken using Superfloc. The results of the bench tests are as follows. Sample 1, Catchment 1 Initial pH = Initial Turbidity = Aluminium Dose (mg/L) Clarity (mm) after 5mins Clarity (mm) after 30mins Clarity (mm) after 60mins Final pH after 60mins Final Turbidity after 60mins 0 1.6 3.2 4.8 6.4 Sample 2, Catchment 1 Initial pH = Initial Turbidity = Aluminium Dose (mg/L) Clarity (mm) after 5mins Clarity (mm) after 30mins Clarity (mm) after 60mins Final pH after 60mins Final Turbidity after 60mins 0 1.6 3.2 4.8 6.4 3 Discussion Insert discussion and conclusion based on the bench testing results. Include recommendation / chemical to be used and dose rate. 3.1 Batch Dose Rate Insert batch dose rate and requirements. 3.2 Rainfall Activated Dosing System Details Floc Shed Tray Size Based on the bench test results displayed in Appendix 3 undertaken on [insert date of testing] the required tray size is XXX square metres per hectare of exposed land catchment draining to the sediment control device. This is the area inside the upstand around the edge of the tray. Sediment Retention Device Catchment area (ha) Tray Size (m2) XX X X XX X X Header Tank Outlet Spacing The distance between the drain and first dosing outlet, and between the two dosing outlets, for a standard header tank made from a 200-litre drum with an internal diameter of 55 cm would be:
