Introduction
The UltraSieve is a pre-filter to filter waste solids from the water. This technique is based upon the
sieve-bend. A sieve-bend consists of hundreds of sharp stainless steel profile wires with very
small slot openings where the water can go through but the solids stay on the sieve bend (see
picture).
In practice it works as follows:
The water enters at
A
and will go upwards and fall over the “self-adjustable” weir (
B
). The water goes through the
sieve bend (
C
) and the waste solids will slowly go down to the waste area (
D
). At the waste outlet of the filter there
is a 90/110mm sliding valve (
E
) to easily wash away the waste with water. When the water in the area below the
sieve-bend will not be pumped away fast enough, the water level will rise which makes the floating system (
F
) go
up to reduce the incoming water flow. The pump is connected at
G
.
UltraSieve Installation instructions
Please read these instructions before you start installing. If you have some questions after reading this manual, please contact your UltraSieve dealer before you start
installing to prevent mistakes. The UltraSieve can be installed in gravity (pond fed), equal to the water level in a direct connection with the bottom drain (and/or
skimmer). Below you see a schematic drawing of a possible gravity installation:
Inlets
The inlets of the UltraSieve are made of 110mm (4”) PP pipe on which you can use the supplied flexible boot fittings. Since the UltraSieve is made of PP you
cannot make glue connections. The UltraSieve has 3 inlets of 110 mm (4”) of which two can be closed with the supplied flexible end caps.
Make sure the UltraSieve is on an equal, level, underground. The
upper edge of the UltraSieve must be 1 cm above the maximum
water level. Between the bottom drain and the UltraSieve we strongly
advise you to use a slide valve to separate the UltraSieve from the
pond when necessary.
Note: Do not install the UltraSieve directly in the soil! Make sure there
is always enough room around the unit. When there is pressure on the
unit it will not work properly.
Waste outlet
The waste outlet is provided with a 90mm Valterra slidevalve for easy clearance of the
waste. Supplied with the filter is a small PVC pipe ring that fits around the slide valve.
You can glue or clamp this piece of pipe around the slide valve the obtain a 110mm
external pipe diameter for standard waste pipe connection.
Pump connection
The UltraSieve comes with a flexible reducer fitting of 90 x 63mm (3” to 2”). The
90mm/3”part fits on the pump outlet of the UltraSieve and the 63mm/2” part can be
used to push the supplied 63mm/2”pipe through towards the end of the UltraSieve to
prevent the pump from sucking in air bubbles (see drawing). Max. flow is ± 40m³/h.
Filling the floaters
The UltraSieve floaters must be filled with ± 1 liter of water each to give it some
counterweight. Fill the gap after filling by pushing the supplied rubber cap firmly into the
hole.
NOTE: Make sure the edge of the UltraSieve is 1 cm higher than the maximum water level
