From the treatment effect point of view, it is much better than the chitosan, and tap water turbidity is below 5NTU, but according to Zonguan Waterworks, the added quantity of the flocculant
is 20 kg per ton of water and the percentage of the polyaluminum chloride in 1 kg of flocculant
is 10%; this value exceeds when CF-PAC is added at 0.2 ml, which is bound to bring in a large quantity of aluminum, which is not consistent with the goal of reducing the tap water content in aluminum.
When geotextile tubes are used for the dewatering of slurry, the addition of flocculant
into the slurry also has beneficial effects in terms of dewatering volume and rate.
By adding flocculants
, the finely dispersed coal particles are first and foremost totally neutralized to lose their stability by charge neutralization.
Yerington goes on to explain that a meter on the pinch valve reads the width of the valve opening, allowing the automated flocculant
system to properly dose the solids again as the material enters the discharge pipe.
Similarly, lack of biodegradability and dispersion of monomers residue in treated water negate the wide application of organic polymeric flocculants
because of its associated health hazards .
Figure 5 shows the effects of flocculant
dosage on the oil removal effect for oily wastewater treatment with P(AM-DMC-MMA), P(AMDMC), and PAC as the flocculant
Cytec claims to be the largest supplier of specialty reagents and flocculants
. In flotation it offers such products as Aero promoters and Aerofloat reagents as well as Aerophine promoters.
Sprinkle credits both the new flocculant
and an extensive training program initiated for plant personnel with these substantial improvements in plant operation:
When running flocculant
settling tests there are two factors to look out for; the settling rate and terminal density.
With the addition of the flocculant
, more negatively charged E1 colloids were neutralized completely and destabilized, and hence the electrostatic repulsion between the colloids reached the minimum.
In this case, the products are used basically as additives into the fluid in the hydraulic fracturing process, to prevent corrosion, as scale inhibitor, as biocide, as gelling agent, frictrion reducer or coagulant and/or flocculant
, among other functions.
Polyelectrolytes can be used alone or in association with other flocculant
aids, such as inorganics salts, surfactants, or even as a second polymer.
