PASES Aqua can evaluate the efficiency and risk of using various flocculants to clear your muddy or cloudy water body.

Flocculant Evaluations & Application

 

Muddy or cloudy waters occur as a result of negatively charged colloidal clay particles repelling each other so that they do not settle out and remain suspended in the water column. Introduction of positively charged electrolytes partially neutralizes the electrical field around the colloids and particles coagulate to form a “floc”, which settles on the lake floor. This process is termed “flocculation”.
 

PASES Aqua supplies the following flocculants for turbidity removal:

  • Aluminium sulphate (alum)
  • Ferric sulfate
  • Calcium hydroxide (hydrated lime)
  • Calcium sulphate (gypsum)

The use of a flocculant requires a thorough understanding of water chemistry and aquatic animal health as the above flocculants can significantly impact pH and total alkalinity. Following water quality testing, PASES Aqua can recommend a flocculant that will efficiently perform its coagulation function whilst maintaining the right water chemistry for the inhabitants within the waterbody.
