Drinking Water Treatment
with Ferric Chloride

technolab el-bahaa group

bahaa badr

Before the 1800’s finding sanitary drinking water in the cities of the world was a risky
enterprise.

The separation of drinking water and human waste was not assured and illness
and death due to water borne diseases was very common.

In the mid-1800’s the
connection was made between water purity and public health.

Once that connection was
made, a concerted effort began to develop water treatment processes that would guaranty
the safety of the populace.

Water
producers soon discovered that the old “tried and true” treatment processes were now
inadequate to meet today’s requirements.

These new requirements made it necessary to
re-evaluate the total water plant operation.

One of the outcomes of this re-evaluation has
been a focus on determining the correct coagulant to meet these new requirements.

However, it has only been in
the past 15 years that a trend towards increased acceptance of ferric chloride for drinking
water treatment has evolved.

This is due in large part to significant improvements in
product economics, quality and availability. Since 1986 there has been a ground swell in
interest in ferric chloride not only for the treatment of turbidity but additionally for the
removal of color, natural organic materials and arsenic from raw waters.

It is produced as a solution from the oxidation
of ferrous chloride with chlorine and it has the unusual distinction of being one of the purest
and most concentrated forms of iron commercially available for water treatment.

However,
what is truly unusual is its chemistry is that ferric chloride not only functions as a reactant to
remove water impurities but it also functions as both a coagulant and a flocculant.

Its
versatility is enormous.

The reactions of ferric chloride in water include an ability to form precipitates with hydrogen
sulfide (H2S), phosphate (PO4), arsenic as arsenate (AsO4) and hydroxide alkalinity (OH).

In drinking water treatment, however, understanding ferric chloride’s reaction with
hydroxide alkalinity is the primary key to understanding its effectiveness as a coagulant/
flocculant.

Ferric chloride reacts in water with hydroxide alkalinity to form various hydrolysis products
that incorporate Fe(OH)3.

These compounds possess high cationic charge which allows
them to neutralize the electrostatic charges found on colloidal compounds and also to bind
to negatively charged particles, including the ferric hydroxide itself.

This ability to bind to
itself is the mechanism for the formation of floc aggregates and the basis for ferric
chloride’s flocculation abilities.

The hydrolysis products from ferric chloride, nominally ferric hydroxide, are different from
those of sulfate based ferric sulfate and aluminum sulfate (alum).

The aggregates or floc
particles of ferric hydroxide are physically more discrete and dense and have a higher
cationic charge density.

In contrast, the floc aggregates of ferric sulfate and aluminum
sulfate tend to be less discrete and “fluffy” or cloud like, this apparently due to differences in
the types of bonding of the hydrolysis products.

These differences translate into
characteristics and abilities for ferric chloride that set it far apart from the sulfate based
coagulants.

In typical plant situations one can expect to use about 30% less ferric chloride
than aluminum sulfate (on a dry weight basis) to achieve similar results.

Ferric Chloride forms a more discrete and dense floc that promotes faster sedimentation
in general and specifically, better sedimentation in cold water.

This dense floc has more
available cationic charge that allows higher reactivity with colloidal solids.

The high ratio of
cationic charge to total mass also makes the ferric chloride hydrolysis products more
reactive and adsorptive with emulsified and semi-emulsified organic matter; such as oils,
fats, and other natural and synthetic organic matter.

This would explain the ability of ferric
chloride to remove TOC and other disinfection by product precursors (DBP’s).
The high density of the ferric hydroxide floc leads to another important benefit for the
treatment plant.

The settled sludge volume of the ferric (chloride) hydroxide ranges typically
from 1/3 to 2/3 that of sulfate based coagulants.

Additionally, the sludge developed through
the use of ferric chloride is generally much more dewaterable. So, although the ferric
hydroxide molecule itself is heavier than the aluminum hydroxide molecule, this does not
translate into more sludge to be disposed .

Instead of, because sludge is disposed of on a
wet basis rather than on a dry basis, the use of ferric chloride produces fewer wet tons of
sludge and yields significant solids handling and disposal savings.
One of the other characteristics of ferric chloride is its ability to form floc over a very wide
pH range as is demonstrated in the accompanying charts.

The charts also show the very
low solubility of ferric hydroxide compared to aluminum hydroxide.

The combination of
these properties allow ferric chloride to function over a very wide pH range with little fear of
carry over into down stream processes due to post precipitation.

This ends up being very
important for operations looking to flocculate at higher pH’s and alkalinity’s while controlling

corrosivity factors in the water.

Additionally, the low end of the pH range becomes
especially important to enhanced coagulation processes.
Although there is little formal data regarding the use of ferric chloride as a filtration aid
there is much operational data that speaks to its ability to greatly enhance turbidity removal
with both slow and rapid sand filter filtration.

Additionally there are more recent reports that
speak to the use of iron coated sand in the removal of manganese.

Potable Water Treatment Applications

· Turbidity removal
· Enhanced Coagulation
· NOM, DBP precursor removal
· Color removal
· Arsenic reduction
· Softening Solids Sedimentation Aid
· Filtration Aid
Summary of benefits
· Very effective in the removal of high and low turbidity
· Extremely effective in removal of color, NOM and DBP precursors
· Works over a wide pH range
· Lower dosage requirements than other sulfate based coagulants
· Low cost
· Makes a heavier floc that settles faster and works better in cold water
· Produces higher sludge concentrations = Lower sludge disposal costs
· High iron content sludge is not considered hazardous to the environment and is
compatible and beneficial with many land application residuals programs
