PAC flocculant 1st grade

PAC flocculant 1st grade Solution: transparent AL2O3: 30 or so Basicity% :70-80 Max. Water insoluble substance% ≤0.3 PH value (1% aqueous solution): 3.5-5.0 SO2-, %, ≤9.8 Ammoniacal nitrogen, %, ≤0.01 Fe, %, ≤0.7 As, %, ≤0.0002 Mn, %, ≤0.0075 Cr 6+, %, ≤0.0005 Hg, %, ≤0.00001 Pb, %, ≤0.001 Cd, %, ≤0.0002 Compared with other coagulants, this product possesses the following advantages. 1. Wider application, better water adaptation. 2. Quickly shape big alum bubble, and with good precipitation. 3. Better adaptation to PH value(5-9), and little declining range of PH value and alkalinity of water after treatment. 4. Keeping stable precipitation effect at lower water temperature. 5. Higher alkalization than other aluminium salt and iron salt, and little erosion to equipments.
