Appearance:
Red brown liquid , readily soluble in water. 10%(W/W)aqueous
solution is a transparent orange solution.
02. Use: As
flocculant in purification of municipal water, industrial water,
waste water, domestic sewage and sludge dewatering.
03.
Features
(compared with other inorganic flocculant):
High-efficiency inorganic polymer
flocculant. NO dilution required , just work out the dose by
trials and use metered dosing.
Good coagulating property. Flocs formed are large and easily
settable.
BIOFLOC is non-toxic. It can capture aluminum, chloride and
heavy metal, and will not cause Fe contamination.
Good effect in decolorizing, capturing oil, bacteria, algae,
reducing COD, BOD and heavy metal.
Low corrosion. Working pH range 4-11, with best performance
at pH 6-9. pH and basicity of water almost do not change after
treatment with BIOFLOC .
Suitable for purification of low-turbidity, low-algae, low-temperature,
low-contaminated raw water. Particularly effective for high-turbidity
raw water.
Low dosage required, save 20%-50% of cost.4. Usage & Caution
Users shall determine the suitability of BIOFLOC for the raw
water to be treated by sample test prior to use.

Usage
& Caution:
Users shall determine the suitability of BIOFLOC for the raw
water to be treated by sample test prior to use.
i. Dosage: Dosage can be determined according to the formation
and settling of flocs by sample test. For treatment of tap water
under identical condition, the dosage of BIOFLOC is equivalent
to polyaluminum chloride, or 1/3-1/4 of that of aluminum Sulphate.
ii. Pump calculated amount of the above working solution into
gauge tank, and add into the raw water to be treated.
iii. Generally the BIOFLOC working solution shall be used right
after preparation. Use pure tap water for preparation. Sometimes
slight precipitation may occur depending on the water used.
iv. Keep close attention to the progress of the application
which may be divided into three stages:
- Coagulation:
Large amount of micro flocs formed in a very short time
after the BIOFLOC working solution is mixed with raw water.
The water turns more turbid. Vigorous stirring is needed
at this stage, usually 250-300r/min in sample test for 10-30S
at the maximum not exceeding 2min.
- Flocculation:
The micro flocs grows to form large ones. Mild stirring
at first and then standing for 10-15min is required at this
stage. In the sample test, stir at 150r/min for 6 min, then
60r/min for 4 min.
- Sedimentation:
water flow shall be very slow at this stage for floc settling.
To achieve high efficiency, lamella settling or flotation
method can be used. In the sample test, stir at 20-30r/min
for 5 min, stand for 10 min, and test turbidity.
v. Compulsive filtration: choose suitable filter material or
filter aid to achieve good capture effect and filtration speed.
This is a key step for improvement of water quality.
vi. BIOFLOC is also available for treatment of industrial
waste water with similar application procedures. It is very
effective for high-colority, high COD/BOD water, particularly
when co-used with other auxiliaries.
vii. For users adopting chemical flocculation, no further
equipment is needed saving the vessel for preparation of BIOFLOC
working solution. 8. BIOFLOC shall be kept in dry places and
away from heat (< 80oC). It is stable for prolonged storage.
