HOUSEHOLD WATER PRODUCED
FROM POND WATER?
Since 1960, the Floating
Pond Filter, consisting
of a housing assembly
and replaceable filter
element, has proven to
be the easiest and most
economical way to remove
clean water from ponds
and lakes. When used in
a well maintained pond
within a controlled
drainage area, a
Floating Pond Filter
provides the cleanest
possible water for final
filtration and
disinfection through a
household treatment
system.
REASON FOR USING A
“FLOATING” FILTER?
Research at the Ohio
State University has
shown the cleanest water
in a pond is
approximately 18 inches
below the surface. At
this level, the water is
below the algae which
floats on the top of the
pond, and above the
turbid bottom water.
Benefits : A floating
pond filter provides the
first step in assuring a
continuous supply of
safe, clean water for
all domestic uses. When
water is taken from the
level approximately 18"
below the pond surface,
the water requires less
treatment to render it
suitable for domestic
use |

HOW DOES A
FLOATING POND FILTER WORK?
Water is drawn through the
replaceable filter element on
the Floating Pond Filter from 18
to 32 inches below the pond
surface. This water has less
color, taste, odor, and bacteria
than any other part of the pond;
therefore, it's more desirable.
The filter removes dirt and
debris which can clog valves on
livestock waterers and cause
excessive pump wear. If the
water is being withdrawn for
domestic use, this cleanest of
water can be disinfected with
less cost and effort.
A floating pond filter protects
and extends the life of your
in-house treatment system and
all pumps and valves.
When the floating filter was
first developed, it was
incorporated into a study
completed by the State of Ohio
Agricultural Research &
Development Center. The study
established that a surface water
intake filter (floating filter)
is an essential component of any
pond water treatment system.

DOES THE FLOATING
POND FILTER HAVE A WARRANTY?
Yes. The filter housing and
float assembly carry a full
5-year warranty.
CAN THE POND
WATER SOURCE BE USED YEAR ROUND?
Yes. When properly installed
with a flexible suction hose,
the filter is not affected by
wind or freezing and will.
continue to operate even under
thick ice.
WILL A FLOATING
POND FILTER DISINFECT POND
WATER?
No. The floating filter is
designed only to remove dirt and
debris. However, it is an
essential first component of our
Water Treatment Plant.

HOW CAN I TELL IF
MY POND IS A
SUITABLE WATER SUPPLY?
Basically, any pond in which 25
percent of the pond is at least
eight (8) feet deep, with a
controlled drainage area and
regular maintenance, is likely
to be a good source of raw
water. By managing the pond for
weeds and algae, maintaining
vegetation on the drainage area,
and restricting the use of
chemicals and pesticides within
the watershed, a pond owner can
protect the quality of the pond
water.
It's also a good idea to consult
state and local Health
Departments when planning for a
pond water system.
IS THE FLOATING
POND FILTER EASY TO INSTALL?
Yes. Normal installation
involves attaching the Floating
Pond Filter to the end of a
flexible suction hose which is
connected to the pipe coming
through the dam wall. The filter
is then anchored in position
using the anchor rope and a
concrete block. The entire
filter assembly is installed
with common plumbing tools, and
complete directions are
included. The Floating Filter
assembly is equipped with a
1-1/4 inch outlet and will
handle flow rates up to 20
gallons per minute.
Benefit: If you use the proper
length flexible suction hose and
an anchor rope guide
(optional), you can easily pull
the filter to shore to change
the filter element periodically.
HOW LONG WILL THE
FLOATING POND FILTER LAST?
All Water Filtration Company
floating filter assemblies are
constructed of heavy-duty,
reinforced fiberglass, PVC
plastic and stainless steel to
ensure many years of
trouble-free service. Filter
housing components are
maintenance-free and will not
rot, rust or corrode. Many of
our original filter assemblies
are still in use after nearly 30
years of continuous service. The
replaceable filter elements will
last one to two years, depending
on the amount of use and the
care and maintenance of the
pond. The element can be changed
in just a few minutes without
special tools or mechanical
skills.

CAN A FLOATING
POND FILTER BE USED WITH A
SUBMERSIBLE PUMP?
Yes. The performance of a
submersible pump used to move
water over longer distances or
to higher elevations can be
enhanced by installing the pump
in our Model FPC-435 Submersible
Pump Cage. The pump draws water
through the Floating Pond
Filter.
Benefits : The pump cage can
extend the life of a submersible
pump by keeping the pump off the
bottom of the pond, by
protecting the pump against
debris and other particulate
contaminants, and by maintaining
proper vertical pump
orientation. The pump cage also
provides easier access to the
pump for maintenance.
HOW IS THE
FLOATING POND FILTER SHIPPED?
All our filters are shipped
completely assembled and boxed.
Most are shipped via UPS.
ARE REPLACEMENT
PARTS AVAILABLE?
Yes. Replacement filter elements
are always in stock and only a
toll-free phone call away. Other
parts, although rarely needed,
are also stocked and available
for immediate shipment.

HOW DOES A
DRINKING WATER TREATMENT SYSTEM
WORK?
Our systems are designed to
provide a continuous,
whole-house, supply of
bacterially safe drinking water
from a pond, rainwater cistern,
spring, or contaminated well.
The treatment cycle consists off
our basic elements:
1. Source Control
and Rough Filtration.
Drawing
water through a Floating Pond
Filter at a level approximately
18” below the water surface
provides the cleanest possible
water for treatment.
2. Chlorination.
Immediately after the pump and
pressure tank, the water supply
is chlorinated using a
automatic, electronic, injection
chlorinator. The chlorinator
injects a bleach solution
directly into the pressurized
water line each time the water
pump runs. The system is easily
adjusted to achieve the proper
chlorine level.
|
3. Retention.
Large fiberglass retention tanks
allow the chlorine to evenly mix
with the raw water. The tanks
are sized to provide a minimum
of 20 minutes contact time with
the chlorine. A 20 minute
contact time with the proper
dose of chlorine ensures a
thorough disinfection of the
water supply.
4. Sand
Filtration.
(optional on
rainwater cisterns) After the
retention tanks, the disinfected
water enters a pressurized,
automatic backflush quartz sand
filter. This filter reduces any
remaining suspended solids from
the water supply. The treated
water is then plumbed into the
main water system.
WHAT ARE THE
SYSTEM CAPACITIES AND
MAINTENANCE?
These systems can be sized to
accommodate any required flow
rate. Maintenance involves
changing the replaceable filter
element(s) in the Floating
Filter and/or Roofwasher, and
refilling the chlorine solution
tank. The chlorinator uses
common laundry bleach.
