TECO Flocculant

TECO Flocculant
Description

High molecular flocculant for Sludge dewatering for bleed off water treatment of wet exhaust gas scrubbers.

 

Features & Benefits

  • Economical to use – significantly lower dosage levels
  • Fast settling rates
  • Achieve high solids removal efficiencie
  • Easily soluble in water; dissolves rapidly
  • Effective over a wide pH range; does not alter the system pH

 

Description

TECO FLOCCULANT is a highly effective anionic emulsion flocculant with a medium degree of charge and high molecular weight. TECO FLOCCULANT is designed for high rate dewatering of sludge from the bleed off watertreatment of wet exhaust gas scrubbers.

 

Advantages

Flocculation is the step where destabilized colloidal particles (or the particles formed during the coagulation step) are assembled into aggregates. The flocculation step can only operate on water/wastewater where the particles are already destabilized by TECO COAGULANT. 


TECO FLOCCULANT is used for dewatering of sludge from the bleed off water treatment system of the exhaust gas scrubber(s). The product is used as well for closed loop as open loop scrubber systems. A high percentage Dry Solids after the dewatering equipment, reduces the amount of sludge to be landed or the be dried.

 

Directions for use

TECO FLOCCULANT has to be diluted to 0,5 - 1 % as stable stock solution. The stock solution has to be diluted 10 times to a working solution. Dilution has to be done by a slow running mixer or a recirculation pump. The flocculantt has to be added to reversed osmosis water.
 
Avoid centrifugal pumps for polymer transfer, high sheer pumps will crack the molecular chains. TECO FLOCCULANT is dosed at a rate of 10 - 20 grams undiluted product per kg Dry Solids (DS). Best is to use a multipoint distribution header, distribution ring or pipe flocculator.
 
As an average a wet scrubber produces:

  • Dry Solids   0,1 - 0,4 kg/MWh
  • Bleed off water   0,1 - 0,3 m3/MWh

Spilled polymer is very slippery and should be absorbed onto an inert material and collected prior to thoroughly flushing with hot water.
 
Agitate the product well before use.
