Floating Solar Powered Circulation System

Upon review of the existing primary sewage treatment system at
Defence R&D Canada Suffield's Cameron Centre, it was determined
that the original system design does not account for the changes
in the weather and precipitation patterns experienced in
Southern Alberta in recent years. It was been determined that
increasing the evaporation rate would be an economic and
sustainable option to improve the efficiency of the system. The
advantage of pond mixing is that the additional circulation of
the effluent contributes to increased evaporation as well as an
increase in effluent quality. 

To that effect we require a floating, solar powered circulation
system as described below:

Minimum Mandatory Specifications;

The system must be made of stainless steel and non-corrosion
polymer construction, with sufficient power supply for day and
night operation - solar powered is deemed essential.

The equipment must be portable and not considered part of the
overall construction of the primary sewage treatment system, and
weigh a maximum of 850 lbs (380 kg) and have an electronic
controller.

The solar panels must be protected from bird fouling, for
example through the use of a bird deterrent kit.

The flotation system must consist of three photovoltaic solar
panels orientated in a triangular pattern with each float arm
adjustable for proper vertical positioning, and a total float
buoyancy of 1,450 pounds (660 kg). It must have an on board
battery and battery storage for day/night operation.

The circulation system must be high torque (Normal Operation
3ft-lb/0.4Nm. Maximum motor rating 30ft-lb/40Nm.), direct drive
(no gearbox), with a low voltage (36 VDC) brushless D.C. motor
which is removable, and both the motor and the electronic
controller must be readily accessible. The controller can be
hard mounted or wireless, but it must be in a weather proof box.

The equipment must be protected from freezing and allow for
continued function even when ice forms on the surface pond.

It must have a minimum operating depth of 0.8 M to ensure no
damage to machine or bottom of reservoir when run dry in shallow
water.

Intake hose: Max length 9M, with no depth adjustment necessary
for fluctuations, as the system must float on the surface of the
water level. Weight, flotation and configuration of the end of
the hose must keep intake above sludge or bottom of pond at all
operating depths and prevent clogging. There must also be an
option to move the strainer up higher if desired.

All the electrical components must be CSA approved.

The system must have a limited parts and labour warranty and
minimum limited 20 year photovoltaic module manufacturer
performance warranty and minimum 10 year motor warranty.

All the deliverables must be received on or before 2013-03-31.
Delivery Date: Above-mentioned
