Free Floating Duckweed Parachute Skimmer
The physical removal of free floating aquatic weeds has several advantages
particularly when infestations are advanced. Partial physical removal increases
the effectiveness of spray applications, such as Free Floating Weed Control by
creating free water to assist the weeds in sinking, reduce the amount of spray
being applied and speed up the overall treatment process. Partial physical
removal or bulk physical removal takes out the nutrient loading held within
the free floating algae.
The Free Floating Duckweed Parachute Skimmer is specifically designed to make
the job of physically removing Azolla & Salvinia quick and easy.
Safe and simple to use, the skimmer reduces the OH&S risks with its easy
action to capture free floating aquatic weeds and remove them from the
water.
Each sweep, captures a path using a tailored screen mesh and as the skimmer
is removed from the water it closes and traps the catch, for easy disposal onto
the shore line or into a wheelbarrow or trailer.
The Free Floating Duckweed Parachute Skimmer is available in two sizes with
course mesh specifically tailored to capture Duckweed.
The large skimmer clears a path of 91cm wide with every sweep and is ideal
for ponds and dams.
The industrial skimmer clears a path of 1.52m wide with every sweep and is
ideal for larger water bodies or to clear smaller water bodies more quickly.
The course mesh size is designed
specifically for capturing all types of
Duckweed/Lemna and Algae.

FREE FLOATING WEED CONTROL
How to Control Free Floating
Aquatic Weeds
APPLICATION RATES
1 litre of Free Floating Weed
Control treats up to 500m 2 of
water surface area, depending
on the density of the floating
aquatic weeds.
Free floating aquatic weeds such as
duckweed, lemna can be difficult to erradicate
due to rapid growth rates.
Effective methods of treatment can vary
depending on the level of infestation.
Treatments are most effective when the
infestations are smaller rather than advanced.
A combination of both a spray treatment and
physical removal is best when the infestation
is advanced and is covering 90-100% of the
water’s surface.
Directions
Suitable for the control of Duckweed, Lemna in
lakes, dams, irrigation channels, water storages
and ponds.
Depending on the density of the floating weed,
it is beneficial to apply several light applications over 1-3 week period, instead of one
single heavy application.
