This facility was going through some pretty decent "growing" pains.
Production at this facility has tripled over the past 2 years and
the load was overwhelming their existing biological lagoon.
They installed a
HydroFloat™ DAF system and immediately saw a 95%
reduction in both FOG and TSS. This brought them back into
compliance (without the addition of any chemicals) and, once
the remaining pieces of the treatment puzzle are in place, they will
be able to discharge directly to open waterways, eliminating their
ties to the municipal treatment system and all the associated costs.
Series Dissolved Air Flotation Cell
Model HF-5 handles up to
10 GPM of continuous flow
(based on application)
Model HF-5 dissolved air floatation system is the smallest
"traditional" style DAF available on the market today.
It is designed to deal with specialized treatment issues of small
wastewater generators or small branch waste streams that you want to
keep segregated from your main wastewater treatment system.
from the highest quality materials the
series DAF should be your first choice when looking for a
dissolved air floatation system. Our smallest DAF
comes with the same standard features as its big brothers.
The Ferris wheel drag skimmer is just one example.
DAFs come pre-assembled, factory tested and ready to
install. They are simple to operate and maintain.
It is everything you could want in an industrial duty DAF, built to
take all the abuse you can throw at it and still keep doing its job
day in and day out.

Hydro Flo Technologies
flotation (DAF & IAF) systems are designed to
accommodate flow rates as low as 5 and as high as 3,000
gallons per minute. The primary function of our flotation systems is to
remove free and dispersed
oils or emulsified oils, along with dispersed suspended solids,
from wastewater or process water streams. This makes it possible for
equipment to perform as designed. A properly designed
flotation (DAF) system will reduce the overall operating costs and improve overall system maintainability.
As a separation device,
flotation systems exhibit
extremely high solids
capture ratios, and will yield the highest
level of recovered solids under a
wide range of flow conditions.
Oil/grease and suspended solids removal rates of greater than 90%
are normal. Hydro-Flo has some customer applications reporting 99.9%
O&G and SS removal. Because of their outstanding performance and
reliability, Hydro-Flo flotation systems
are the preferred process for a wide range of industrial
water and wastewater treatment problems.
Series Dissolved Air Flotation
Technologies' dissolved air flotation technology, or "DAF", is an
effective, economical process for removing hard to separate
suspended solids from wastewater and also for resolving overall
water clarity issues.
The HydroFloat™ series of DAF is considered to
be a "traditional" DAF design. However, Hydro-Flo has
optimized all aspects of this design through years of research,
development and experience in the field.
Series Inclined Plate (Lamella)
Hydro-FloTechnologies' FloatPac™ series of dissolved air flotation technology
takes floatation system technology to a whole new level.
We achieve these results through the
combination of Hydro-Flo's proprietary co-current / counter-current
inclined plate (Lamella) technology with our state-of-the-art DAF
This hybrid package generates greater
removal efficiencies than those that can be achieved in traditional DAF designs.
It also gives the user the option to operate
the unit as a highly efficient clarifier for the removal of
settleable suspended solids. If you are dealing with waste
streams that sometimes settle and sometimes float, this is the
system for you.
The Hydro-Flo HF-5 meets world wide demand...
When we first introduced this little dynamo, we thought that it
would function as a pilot unit for large scale treatment studies.
What we didn't realize is that there are literally thousands of
small scale applications world wide. Units have been sold to
small production facilities throughout North America, Central and
South America and units are planed for shipment to Asia and Europe.
If you are a small scale producer with a difficult treatment issue,
the HF-5 might just be the answer to your problem.
Chemical pretreatment for
Chemical pretreatment is not always needed
with flotation systems. When used, chemical
pretreatment allows for the separation and removal of contaminants a DAF
or IAF alone will not remove.
Most pretreatment applications require the use of acids, caustics, coagulants and flocculating polymers. The
more common coagulants are inorganic salts, such as alum, ferric
chloride, ferrous sulfate, lime, sodium hydroxide or organic
polymers. Preconditioning requirements are usually site specific
and will impact operating cost, effluent quality, sludge volume and
possibly water reuse.
The Hydro-Flo Technologies dissolved air flotation and induced air
flotation systems can handle
difficult wastewater applications as stand alone
systems, or with any combination of chemical inputs, including
liquid polyelectrolytes, dry powders, and organic and inorganic
wastewater chemicals with various injection rates.
Hydro-Flo's customers have the opportunity to
utilize our wastewater tech resources located in St. Charles,
Illinois, USA. Instead of sending a grab sample (which may or not be
truly representative) to our facility for
analysis, we dispatch a chemist to your site in order to review your
entire process. Representative wastewater samples are taken
and jar tests conducted on site to identify the most cost effective
chemical pretreatment program. A lab test study will also
determine the most relevant equipment for your application.
Our on site lab tests also tell us the proper chemical treatment,
proper mixing times, as well
present us with a good understanding of how
and where to locate the chemical injection points in the piping
system ahead of the flotation system. Lab studies identify approximate operating
costs and wastewater cost savings. All of this information is very
valuable and necessary in order to develop the proper chemical
the proper sizing of the separation systems.
