Geotube Sludge Dewatering Primary Cationic Flocculant
Polyacrylamide High Molecular Weight
General Of Blufloc Cationic Polyacrylamide:
- Blufloc C8020 is a high molecular weight cationic polyacrylamide,
used for use in a range of industrial and process applications
including the treatment of wastewater streams, it is a versatile
polymer product and is particularly useful for wastewater treatment
applications including belt filter, centrifuge and screw press de
watering, water clarification, filtration, thickening or use in a
Dissolved Air Flotation plant.
- Millions of gallons of sludge have been pumped into Geotube
containers for containment and dewatering of industrial waste,
municipal sludge, and marine sediments. Paper mills, chemical
companies, and nuclear power plants are just a few of the clients
that have benefited from Geotube technology.
- Geotube dewatering containers are supplied to site and placed into
position. Sludge which is treated with specialist polymers is then
pumped into the containers and the clear effluent water is then
drained leaving the solid remains within the container. When full
the containers can be disposed at a landfill or the solids removed
- Blufloc Cationic series flocculants are also offered in a range of
molecular weights. This enables the customer to select the optimum
polymer depending on application needs, such as low molecular
weights for low shear applications (e.g. gravity belt thickener) to
very high molecular weights for high shear environments.
General Sludge Treatment Process:
Dewatering with Geotube technology is a three-step process:
Step 1: Filling
|Sludge (dredged material) is pumped into the Geotube container.
Environmentally-safe polymers are added to the sludge, which makes
the solids bind together and water separate. The Geotube
container's unique fabric confines the fine grains of the material.|
Step 2: Dewatering
|Clear effluent water simply drains from the Geotube container
through the small pores in the specially engineered textile. This
results in effective dewatering and efficient volume reduction of
the contained materials. And this volume reduction allows for the
repeated filling of the Geotube container. Over 99% of solids are
captured, and clear filtrate can be collected and recirculated
through the system.|
Step 3: Consolidation
|After the final cycle of filling and dewatering, the solids remain
in the bag and continue to densify due to desiccation as residual
water vapor escapes through the fabric. Volume reduction can be as
high as 90%. When full, the Geotube container and contents can be
deposited at a landfill, remain on-site, or the solids can be
removed and land-applied when appropriate.|

How to Use Blufloc Polyacrylamide?
Application and Dosage:
The dosage range of varies from 0.2 - 3.0 ppm depending upon the
type of effluent and application. It is always advised to do a jar
test for evaluating the functioning and approximate dosage.
Put sample of effluent in a beaker and add it as designated,
agitate for 1 minute at 100-120 rpm and then slowly agitate at
60rpm. Determine the floc properly at this time and note the
sedimentation and clarity of top solution.
Procedure and precautions upon dispersion and dissolving
Dissolving time: The time required to dissolve the flocculant
varies according to the type of flocculant, water quality,
temperature and agitation. However, most flocculants generally
require around 1 hour of agitation to completely dissolve the
powder. Incomplete mixture of flocculant or lumping may inhibit the
performance of the flocculant.
Agitation speed: The ideal revolution of the agitator is between
200-400rpm. A high speed agitator operating without reducing the
revolution of a motor is not advised, since it may cut the
molecules of the flocculant. An ideal agitator motor should be of
1HP for a 1-2m3 mixing tank.
Dissolving concentration: Flocculants should be standardly be
dissolved to 0.1-0.2% concentration. It is also effective to start
dissolving at a slightly higher concentration, and then dilute the
flocculant mixture immediately before use.
Handling measures and precautions:
Proper human safety products such as Splash goggles, lab coat,
vapor respirator, gloves and boots should be worn while handling
and applying chemicals. Splashes on skin should be washed off with
water immediately. In case of splashing into the eyes, flush it
with fresh water and obtain medical attention. Should not be
injected. Please refer MSDS for more details.
