DAHFLOC 6502 for wastewater containing suspended particles of anionic charge, and the charge in addition to the adsorption and bridging, so that good formation of aggregation (FLOC) outside; dissolved in water can be combined with the anionic water-soluble substances, insoluble in forming The water complex, and then be aggregated, precipitated. Therefore, the market can handle the existing wastewater plant dyeing bleaching agent could not be dealt with aggregation, and removal of active agents.

Apart from the above, DAHFLOC 6502 also called the epoch of new products, which can be particles of colloidal aggregation of sludge and sewage sludge, and to precipitate.

 

[General characteristics]

            
Appearance: colorless transparent liquid

       
Viscosity: about 100

              
PH (2% soln.): Approximately 4

 

Product Features

 

1. DAHFLOC 6502 is a liquid product, very easy to use.

2. DAHFLOC 6502 to neutralize the negatively charged cloud wastewater suspended particle surface and connected fracture molecules, thus achieving an excellent aggregation effect.

3. DAHFLOC 6502 capable of dissolving in water the anionic dye pigments (particularly difficult to deal with waste of the red line), surface-active agents, (such as refining agent, dyeing auxiliaries) mixing an anionic water-soluble substances, cohesion of water-insoluble complex, then put their aggregation and precipitation from wastewater.

4. DAHFLOC 6502 for colloidal sludge, sewage sludge and suspended particles hydrophilic protective protein sludge particles or hydrophilic surfaces (mainly bacteria sludge particles in the effluent, the height of the water and, hinder the collection of sludge particles) can be aggregated and hydrophobic particles

[Note]

 

1 To use the same bath time with other agents, please first confirm their compatibility and stability is correct, then moved on-site use.

2 manufacturers handle materials, different devices and operating conditions, so please make a small test, self-confirmation, then moved on-site use.

 

[Use]

 

When DAHFLOC 6502 alone, the effect of that is very significant; it is usually with an inorganic coagulant, such as: aluminum sulfate, polymer of anionic / non-ionic aggregation agents and use.

 

The following are only the representatives DAHFLOC 6502 using the sample list, that reference:
