Wastewater and sludge volume ratio~ One-dose powder flocculant has lower water content and sludge volume than polyaluminum chloride (PAC)!
Polyaluminum chloride (PAC) is a common wastewater treatment chemical that forms a high amount of sludge. Increase the burden of sludge removal~
One-dose powder flocculant replaces PAC and polymer flocculant, producing only a small amount of pollution Mud completes the treatment of wastewater~
Actual test case: One-dose powder flocculant v.s polybasic aluminum chloride (PAC)
Additive dosage: 500 mg/L each of one-dose powder flocculant and polyaluminum chloride
Response time: 15 minutes
Reaction PH: 7-8
Explanation of actual measurement: In order to understand the situation of adding sludge to wastewater and the speed of sludge settling when two chemicals are added to wastewater. The two agents were put into 250 mL of water respectively. Under fixed reaction time and pH value, the two sets of results on the left and right of the figure below were obtained. In terms of the height of the sludge layer, the height of the sludge layer after adding a dose of powder flocculant (left) is only four to one-fifth of that of polyaluminum chloride (right). Due to the small volume and high density of the sludge formed by the one-dose powder flocculant, the settling speed is significantly greater than that of polybasic aluminum chloride.
The following is a further comparison of the two processing methods:
| One-dose powder flocculant< /td> | Polymeric aluminum chloride | |
| Dosing type | One dose added | Two agents added (coagulant, polymer coagulant) |
| Convenience of operation | Easy to add in one dose | The ratio of the two doses needs to be adjusted by bottle and cup testing |
| Add method | Powder addition | Liquid addition |
| Storage method | Powder storage (20KG/bag), stable and not easy to deteriorate | When storing liquids, attention must be paid to leakage and personnel safety |
| Sludge type | Tight, and the disturbance is not easy to disperse | Loose and soft, easy to disperse fine particles after disturbance |
| Other features | Can adsorb trace amounts of surfactants, making wastewater less likely to foam | None |
