NFSSS Nano Flocculant   

NFSSS Nano Flocculant was developed by the School of Environment, Tsinghua University and jointly produced by BPT and the School of Environment, Tsinghua University. It is a high-efficiency nanocomposite flocculant based on inorganic nano iron particles which are made of metal oxide nanoparticles combined with special organic charge carriers.

The flocculation settling mechanism of NFSSS Nano Flocculant is mainly adsorption neutralization. The negatively charged sludge neutralize positively charged nanoparticles, which reduces the zeta potential and the electrostatic repulsion. In addition, it is supplemented with bridging adsorption. Chain molecules of polymer transfer the suspended solids into a flocculant. Therefore, NFSSS can achieve rapid sludge-water separation by making sludge quickly form flocs to settle rapidly.

   NFSSS Application scope    

NFSSS Nano flocculant is a liquid, which is a non-hazardous and non-toxic composite product. It can achieve rapid settlement of activated sludge based on the adsorption neutralization and bridging adsorption.

• Solution of slurry run-out problem caused by sludge expansion

• Increase the sludge settlement speed of the primary and the secondary sedimentation tanks, and increase load

• Increase the concentration of activated sludge and the scale of sewage treatment plants.

• Excess sludge dewatering and volume reduction

• Solve the problem of non-compliance caused by CSO in summer

     NFSSS Usage    

Dosing point: inlet channel of sedimentation tank

Dosage: 10-50ul/L；

Directions for use: Direct injection, dilute 10 times would expect better performance

   NFSSS纳米絮凝剂  优点   

NFSSS is a liquid composite nano-flocculant with a certain viscosity. After dilution, it can be directly metered and added. Compared with traditional coagulation-flocculation, it reduces the steps of dissolution and multi-step reaction, simplifies the operation process, and increases the reaction speed, and it doesn’t need to increase the coagulation reactor.

1. One-step dilution, operate easily

2. No need for a separate reactor, saving capital construction costs

3. Short reaction time and good flocculation effect

4. Save precipitation time and increase the processing load

5. High safety, no effect on activated sludge

6. With auxiliary phosphorus removal function
