Waste water, if left untreated, is a major source of
pollution for the environment.
The importance of treating liquid effluent is
continually on the rise as we need to substantially reduce the level of
contaminants that liquid effluent contains, so that it can be safely discharged
back into the environment or recycled.
Volumes of generated sludge are also increasing following the
improvement of the efficacy of effluent collection, generating new concerns
Lonza proposes a different approach to waste water treatment:
Organic coagulants such as our range of
Barfloc® FP products offer solutions that can reduce sludge up to 30% and can
improve sludge thickness.
Barfloc® FP products facilitate better
drainage of the interstitial water when used alone or synergistically with
inorganic salts such as FeCl3 and PAC. A reduction of 50% of the
necessary dose of inorganic salts can be achieved due to the high cationicity
of the product, lowering the metal content of the generated sludge (better in
cases when spreading on agricultural land), and resulting in fewer ashes when
the sludge is incinerated.
Our active chlorine-based solutions are also
the technology of choice as tertiary treatment, helping to reduce odors,
bacterial counts and organic content (residual COD) in the discharged effluent.
