SECTION 2


2 Sequencing Batch Reactor (SBR) Decanter Modifications 2.1 General Description The work associated for this improvement includes the modification of the two existing decanters in each SBR basin using new decanter equipment furnished by the Seminole Tribe of Florida (STOF). The equipment has been supplied by Xylem/Sanitaire and generally includes decanter heads, actuators, control panels, and variable frequency drives.

Items to be furnished by STOF and installed complete by the Contractor:

1. Two decanter heads and rods

2. Two actuators - inclusive of four (4) limit switches per actuator

3. Two (2) NEMA-4X 316L SS control panels, one for each decanter. These panels will provide local control of the decanters and will be tied to the existing Plant SCADA system for remote auto control and monitoring. Contractor shall provide integration into the plant SCADA system.

4. Two (2) Allen-Bradley Powerflex 700 variable frequency drives (VFD), one for each decanter. Each VFD will include a NEMA-1 enclosure and both shall be wall-mounted in the electrical room of the Operations Building.

The submittal provided by Xylem/Sanitaire has been included as part of this Scope of Work. Modify hand railing as shown on submittal drawings to accommodate decanter actuator. Add two stainless steel chains across removed handrails as shown.

The Contractor shall install two decanter systems, one for SBR-T-1 and one for SBR-T-2, with the installation of each to be wholly independent of the other with the lone exception of shared conduits for cable routing purposes. The Contractor shall perform all required load and short circuit calculations furnishing the required engineering documents signed/sealed by a licensed professional engineer in the State of Florida and furnishing and installing all the required material and labor not being furnished by STOF, making both decanter systems fully operational.

• Positive, mechanical positioning • Uniform lifting speed • Multiple arrangements • Anti-backlash (optional)

Features

Capacities from 1/4 Ton to 250 TonsWorm Gear Ratios from 5:1 to 50:1

Because the Duff-Norton machine screw mechani-cal actuator is produced in many standard modelswith a wide range of capacities, there is a standardmodel for almost any requirement. Models can befurnished to 250 tons capacity.

Operated manually or by means of gear motors,machine screw actuator models can be used singly,in tandem or in multiple arrangements (see page133). Since most capacities have a uniform liftingspeed, added economy can be realized in raisingunevenly distributed loads by operating the differentcapacities in union.

Most Duff-Norton machine screw actuator modelswith higher ratios are self-locking and will holdheavy loads in position indefinitely without creep.They can be used to push, pull, apply pressure andas linear actuators. They are furnished with standardraises in increments of 1 inch. Depending upon sizeand type of load, models are available with raises upto 20 feet.

Functional Design Specification Big Cypress WWTP, FL USA Project #14-8476A Xylem Sanitaire Products Page 2

1.0 Introduction Xylem – Sanitaire Products is the provider of the Sanitaire process and associated equipment. This functional design specification (FDS) details the control of each system component, interlocks between components, operating ranges and how to change control set points. This FDS is specific to the following plant:

Project Name: Big Cypress WWTP Project Location: Clewiston, FL, USA Sanitaire Number: 14-8476A Process/Basins: Decanter, 2-Basin

Major Components 1.1Sanitaire has provided a equipment for operating the Decanters. The major components provided by Sanitaire for this system will include the following: Decanter Local Control Station Decanter Variable Frequency Drive (VFD)

2.0 Control System In general, the control system consists of a Decanter Local Station and Variable Frequency Drive. (VFD) Customer is responsible for providing external process control of supplied equipment specific for their process. Sanitaire is not responsible for process interruptions or effluent discharge quality. Each basin has a decanter installed on the wall opposite the pre-react zone. An electro-mechanical actuator controls the movement of the decanter. A selector switch is located on the decanter’s local control station with the following positions: lower, off, auto, or raise. To manually operate the decanter up or down, the operator must select “raise” or “lower”, respectively. To stop the decanter from operating, the operator must select “off”. In the “auto” position, the decanter will operate based on the customer supplied external controls.

Decanter Actuators and Limit Switches 2.1The electro-mechanical actuator is driven by a VFD to control the speed of the decanter. In manual operation, the decanter will travel at full speed in the direction selected. In automatic control, the decanter’s lowering speed is controlled by the VFD to provide extended vertical travel time for the decanter weir, which results in a variable effluent discharge rate. When the decanter is rising, it will travel at full speed. Duff Norton The decanter has magnetic upper and lower limit switches to define the range of motion and end of travel in either direction. There are four (4) limit switches, two (2) at the top called raised and secondary raised and two (2) at the bottom called lowered and secondary lowered. The secondary limit switches operate as backups in case the first limit switch fails to operate.


Decanter Travel Time 2.2To set the total decanter lowering travel time, there is an operator adjustable value on the VFD for lowering speed in “Auto” only.

Parameter Displayed Selection Options Preset Speed 1 [Parameter 101] 0 – 60Hz

If the decanter travel time is not in the desired decant time range of X minutes, the operator will have to adjust the decanter speed accordingly. If the decant time is less than the desired time, the decanter speed must be decreased, whereas, if the decant time is more than the desired time, the decanter speed must be increased. After the decanter has reached BWL, it should begin rising at full speed until reaching the raised limit switch or “Park Position”.

Decanter Permissive Conditions 2.3To operate the decanters automatically, Sanitaire suggests that the following conditions if applicable should be interlocked with the actuation of the decanter:

Action Permissive Conditions Call to Lower Decanter in “auto” position at the local

selector switch Decanter called to lower from external

controls based on cycle phase (decant phase)

Basin air valve closed Mixer not running

Action Permissive Conditions Call to Raise Decanter in “auto” position at the local

selector switch Decanter not called to lower, raised limit

switch not activated. Decanter not at park position (raised limit

switch) when basin is not in decant phase If the decanter’s lower limit switch is not reached before the beginning of the react phase, the decanter should “time out” and then begin rising to reach the park position. If the decanter is taken out of “auto” when it is traveling between limit switches, it will continue to lower if switched back into “auto” before the end of the decant time. If the decanter is not switched back to “auto” within the decant time and is switched to “auto” during the other phases in the cycle, it should begin to raise to reach the park position.


Decanter Faults and Warnings 2.4Sanitaire suggests operator interface should display a fault or warning when the decanter has one of the following conditions:

Status Status Conditions Faulted Top Fault (decanter failed to raise from

BWL to park position within X minutes) VFD fault Move fault (VFD not running)

Status Status Conditions Warning Decanter secondary raised limit switch

(raised limit switch failed) Decanter secondary lowered limit switch

(lowered limit switch failed) When a warning is displayed, the decanter should continue to operate and the operator must correct the condition to clear the warning.

Decanter Lubrication Reminder 2.5Sanitaire suggests the operator interface display a reminder that will alert the operator that it is time to lubricate the decanter actuators. This reminder should occur every 30 days of plant operation. This alarm is only a reminder and is not intended to alert the operator of all the maintenance items required for the decanters. Refer to the O&M manual for the decanters. All other equipment maintenance should be completed as detailed in the O&M manual. The lubrication reminder will be as follows:

Parameter Displayed Status Options Decanter Lubrication “Reminder: Lubricate Decanter Actuators”

(see O&M manual for other maintenance items)
