.3 Use a centreline radius not less than 1-1/2 times the width of the duct in the plane of rotation of the radius for all bends, tees and elbows unless dimensioned otherwise. Where this radius is not possible, fit formed airfoil blade duct-turns of approved design in low velocity ductwork. Obtain approval from the Consultant before using splitters or radii larger than 1-1/2 duct width.

.4 Construct transitions with maximum expansion angles of 30 degrees and maximum contraction angles of 45 degrees.

.5 Construct collars between ducts and diffusers with length equal to or greater than the diffuser neck diameter. All grilles, dampers and diffuser accessories are the same manufacturer as the diffusers.

.6 Make straight collars between the supply ducts and grilles not less than 300 mm in length and provide individual adjustable blade type distribution grids at the connection. Provide suitable cushion heads at the end of the low-pressure ducts.

.7 Duct dimensions shown are required clear inside dimensions. Where internal insulation is used, increase sheet metal dimensions by the thickness of the insulation maintaining the net dimensions shown.

.8 Support vertical ducts where they pass through the floor using angles, riveted and/or bolted to the duct, bearing on the structure with rubber pads. In addition, where required seal all openings around ducts and pipes with sheet metal of sufficiently heavy gauge to constitute a fire, noise and smoke separation. The separation must have a rating to match the rating of the barrier through which the ducts and pipes are passing. Use galvanized clamps drawn tight to support round ductwork at the floors, bearing on the structure with rubber pads. On exposed ductwork, provide galvanized angle collars to conceal the above construction both above and below the floor.



.9 Leave a smooth interior surface on all seams and joints. Break the corners and groove the longitudinal seams using Pittsburgh lock, button or lock slide or double seam corners. Bolt all bracing with backing plates. Do not use aluminum pop rivets.

.10 Construct ductwork in accordance with SMACNA standards.

.11 Fittings are of the slip joint type with all 90 degree elbows of the fabricated 5 piece type or miter elbows where shown on drawings. No crimping of the fittings is allowed. Lap all joints in the direction of airflow wherever possible and make them smooth on the inside. Stagger lockseam joints at least 90 degrees.

2.2 Mechanically Cleaned Screen

.1 General

.1 The screen shall be designed to provide maximum solids filtration and thus maximize capture of debris and minimize rate of head loss increase through the screen. This



shall be achieved by means of one piece perforated curved filter elements. The maximum openings shall be 2 mm. The screen will be operated intermittently by means of differential head measurement.

.2 The screen shall be securely anchored to the top of the channel and designed to resist all forces generated in the event of a full channel depth of 11.04 ft on the upstream side and no water on the downstream. Routine service, repair or replacement of damaged parts, shall be possible with the screen in the channel.

.3 The use of roller chain, filter shafts and rollers and/or two or more motors for screen rotation is not acceptable. Screens which run the chain rollers on metal supports will not be acceptable.

On every fifth screen panel a set of static, non engaging 'finger' type lifters shall be attached to the lower edge of the panel, designed specifically to lift spherical and large size solids (stones, cans, bottles, rag clumps etc) from the bottom of the channel. A submerged curved 1/2" thick stainless steel plate shall be provided at the foot of the screen to prevent ingress of stones and grit creating wear on the elements. A revolving lower guide arrangement consisting of two life sealed bushings, two 3.15" diameter stub shafts and two bolts on 7.87" pitch x 3/4" thick discs shall maintain accurate alignment of the screen elements. To prevent metal to metal wear and bearing damage no submerged roller bearing wheels and spindles will be allowed. Screens which do not support the drive chains on the downstream side will not be approved. Screens that use lifting ledge on top of the panel thereby preventing the removal of solids from the bottom of the channel floor will not be permitted.

.2 To prevent deflection, the one-piece filter elements shall have a minimum thickness of 1/8" and shall be made of curved 304 stainless steel. This is required to insure structural integrity and smooth operation. Engaging tines, fingers or engaging elements, which can bind or jam, will not be acceptable.

.3 The screen shall be automatically self-cleaning through the interaction of the one piece filter elements with the cleaner brush. The drive mechanism shall be designed to insure that the screen runs smoothly without jamming. A series of stationary 304 stainless steel lifters shall be fixed at intervals on the screen elements. They will be designed to remove spherical solids from the bottom of the channel, which may otherwise roll back



off the screen face and accumulate thus creating a wear problem as the screen elements are moving thru the solids as they ascend on the upstream side of the screen. The screen panels will be driven at a speed of 15 fpm during normal operation and 30 fpm during high flow or high water levels. The screen must be able to operate at a speed that keeps pace or exceeds the accumulation rate of the screenings during a storm event. Single speed motors driving the screen band at 10 fpm will not be approved.

The roller wiper shall turn at max 20 rpm and function to direct all solids removed from the screen by the revolving brush cleaner and direct them to the screenings discharge flume attached to the screen discharge. conveyor. The rotating deflector prevents bypassing of solids into the downstream channel. The controls for operating the roller wiper shall be provided with the FSM screen control panel, and the wiper shall operate whenever the screen is turning.

.3 Filter Screen Belt

.1 The screen filtration belt shall be provided with one piece perforated curved elements, which limits the maximum opening to 2 mm in any direction. This restricted opening profile prevents long thin materials from passing through the openings. The screen shall have a maximum 0.80 square feet of contact surface per square foot of wetted filtration surface area.

.2 No cleaning devices which cause trash to be pushed or dropped into the interior of the filtration belt will be allowed.

.3 Due to the risk of high differential levels on the screen, in the event of a power failure, excess solids load condition, mechanical breakdown etc. the screen shall be designed to withstand a maximum differential head of 11.04 ft measured from the upstream water level to the downstream water level. The manufacturer shall provide calculations showing that it will meet this requirement. A test will be conducted at site, before the screen or screens are accepted, during which time the screen will be tested for a minimum period of two hours at the specified maximum differential head condition.

.4 Should the screen fail this test, for example there is bending, bowing, buckling or other significant signs of mechanical damage then the screen shall be removed at the manufacturers cost.

.5 The horizontal space between adjoining screen panels will not exceed the specified screen opening at any point between any adjacent panels. The screen manufacturer shall make a witnessed measurement of the screen panel adjoining spaces before acceptance at site and if more than 10% are greater than the dimension of the specified screen perforation the screen will not be accepted until the manufacturer has corrected the problem and a re-measurement as above confirms the specification has been met.

.6 To control the build up of biological slimes behind the screen panels, a 2 inch diameter internal spray water wash spray bar will be provided, manufactured from 304 stainless steel. The spray bar will be attached in the internal space between the rotating screen panels and the spray water will be directed to wash each screen panel as the panel



moves past the spray nozzles. The spray bar will supply approximately 7 gpm at a pressure of 25 psi. The spray orifices will be non-plugging and suitable for use with treated effluent water. A minimum 1" NPT connection will be located on one side of the screen frame above the operating floor level and the water supply connection will include an inline strainer, manual operated gate valve, and solenoid valve suitable for attaching to the 1" NPT connection.
