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 below).

In practice it works as follows:
The water enters at A and will go upwards and fall over the "auto-adjustable" dam (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 (E) is a
90mm sliding valve to easily wash away the waste with water. When the water in the tank underneath the sieve-bend
will not be pumped away fast enough the water will raise which makes the floating system (F & B) go up to reduce the
incoming water flow. The pump will be connected to the fitting 2" x 63mm(G). You can use a self-priming pump like a
Whisperflo or Speck or a submersible pump that can be used out of the pond like AquaForte pumps.

An extra advantage of this pre-filter is that the water will be provided with extra oxygen,
when it goes through the slots.
