Technology Description:
Floating, solar powered, circulation equipment. Two mixing flows for maximum
nutrient (N and P) reduction, in addition to BOD/TSS reduction in partial mix and
facultative wastewater treatment systems. Day/night operation on solar only by
utilizing a battery to store excess daytime power for nighttime operation.
Flow Rates:
Flow rates at full speed at 10 feet (3 meter) diameter.
Direct Flow Rate - Day
3,000 gallons per minute, (12,000 Liters per minute).
Induced Flow Rate - Day
7,000 gallons per minute. (26,000 Liters per minute).
Combined Flow Rate - Day
10,000 gallons per minute. (38,000 Liters per minute).
Combined Flow Rate - Night
10,000 gallons per minute (38,000 Liters per minute).
Lower Mixed Zone Flow Rates:
Flow rates at full speed at center of machine.
Direct Flow Rate - Day
150 gallons per minute. (600 Liters per minute).
Direct Flow Rate - Night
150 gallons per minute (600 Liters per minute).
Machine Size/Weight:
Assembled machine is 16 feet (5m) in diameter and weighs 850 pounds (380kg).
Shipping Size/Weight:
Machine can be crated and shipped in a 87 inch (2.2 m) wide X 87 inch (2.2 m)
long X 65 inch (1.7 m) high crate, estimated shipping weight is 1500 pounds (680
kg). Hose lengths greater than 20 ft (6 m) may require additional crating.
Materials of Construction:
316 stainless steel construction. Foam-filled high-density polyethylene (HDPE)
floats. Thermoplastic rubber, stainless steel reinforced intake hose. Concrete
mooring blocks are encapsulated in HDPE.
Drive System:
High torque, direct drive (no gearbox), low voltage brushless D.C. motor.
Power Supply/Control System:
PV solar panels are protected from bird fouling with bird deterrent kit.
PV Solar Panels
3 X 80-watt photo voltaic solar panels orientated in triangular pattern. On-board
battery storage for 24-hour operation.
Electronic Controller
Digital solid-state controller, mounted in weather-tight (NEMA 4X) enclosure with
externally fused disconnect. SCADA output through RS-232 serial communication
(Modbus RTU), DB9 male connection point inside enclosure. Wireless options
available, not included.
Wiring
Corrosion-resistant industrial cord with molded watertight connectors that are
indexed to prevent improper wiring.
Rotating Assembly:
Removable assembly with easy access to motor and digital controller. Impeller
handles 4-inch (10cm) spherical solids. Oil-filled (food grade) teflon freeze sleeve
with o-rings, shaft. Rotational indicator on shaft.
Flotation System:
Three floats in triangular pattern each with an adjustable float arm for proper
vertical positioning, total float buoyancy of 1,450 pounds (660kg).
Upper Mixed Zone Fluid Intake
Assembly:
Bolted to bottom of structural assembly.
Intake Type
Fixed horizontal plate with 12-inch (31 cm) openings.
Intake Depth Adjustment
No adjustment necessary. Horizontal inflow from 25in (64cm) below distribution
dish.
Lower Mixed Zone Fluid Intake
Assembly:
Bolted to bottom of structural assembly.
Hose System
12-inch (31 cm) diameter X 20 feet (6 meter).
Intake Type
Inverted bell shape strainer with 3-inch holes (7.6 cm).
Intake Depth Adjustment
There is no adjustment necessary for fluctuations in water level. Weight and
flotation of the ‘J’ bend of hose keeps intake above sludge at all operating depths.
Strainer can be chained up higher if desired.
Anchoring:
(1) Two mooring blocks tethered together with SS chain and attached to structural
member on unit or (2) Tethered to shore with SS cable.
Ice Protection:
Freeze sleeve and positive pumping under distribution dish to maintain circulation.
Minimum Operating Depth:
36 inches (0.9 m). No damage to machine or bottom of reservoir when run dry in
shallow water.
Accessories Available:
(1) Supplemental Shore Power Kit, (2) Chemical Injection Kit, (3) Marker Light Kit
Life/Maintenance/Warranty:
Expect 25-year life, minimal maintenance. Limited 2-year parts and conditional
labor warranty. Limited 25 year photovoltaic module manufacturer performance
warranty and 10 year motor warranty.
