NOTES:

1.) EQUIPMENT FURNISHED BY WESTECH IS DESCRIBED IN A SEPARATE EQUIPMENT LIST.

ADDITIONAL PIPING, PIPE SUPPORTS, AND CONNECTION FITTINGS, AIR PIPING, CONDUIT,

WIRING AND MOTOR CONTROL CENTER ARE NOT INCLUDED WITH STANDARD UNIT.

MAJOR EQUIPMENT AND COMPONENTS TO BE INSTALLED AT THE JOBSITE BY THE

INSTALLING CONTRACTOR.

2.) EQUIPMENT PAD DESIGN IS THE RESPONSIBILITY OF THE CONSULTING ENGINEER.

CONSTRUCTION OF EQUIPMENT PAD IS BY OTHERS.

3.) PIPE SUPPORTS ARE NOT SHOWN. SUPPORTS TO BE DESIGNED BY THE CONSULTING

ENGINEER AND SUPPLIED BY THE INSTALLING CONTRACTOR. DO NOT SUPPORT PIPING

OR OTHER STRUCTURES FROM THE TANK OR TANK PROJECTIONS.

4.) DESIGN AND APPLICATION FEATURES ARE DESCRIBED IN TYPICAL SPECIFICATION

SHEETS, TECHNICAL DATA SHEET, FLOW SCHEMATIC, ELECTRICAL DIAGRAM AND

ELECTRICAL SCHEMATIC. ARRANGEMENT SHOWN IS FOR GRAVITY DISCHARGE TO

BELOW-GRADE FINISHED WATER STORAGE.

5.) THE STANDARD DESIGN IS FOR INDOOR INSTALLATION.

6.) EITHER CHECK VALVES OR BACKFLOW PREVENTERS ARE REQUIRED IN BACKWASH

LINES AND FURNISHED BY OTHERS (NOT SHOWN ON DRAWING).

7.) AUTOMATIC RATE OF FLOW CONTROL LOOPS ON EACH INFLUENT LINE MAINTAIN THE

PRE-SET FLOW TO EACH UNIT. FLOW SET POINTS INTERLOCKED WITH FLUSHING AND

BACKWASHING CYCLE.

8.) FILTER LIQUID LEVEL CONTROLLERS OPERATE FILTER EFFLUENT AND

FILTER-TO-WASTE MODULATING VALVES TO MAINTAIN CONSTANT FILTER LEVEL.

9.) FILTER CONTROL CIRCUITS PROVIDE FOR AUTOMATIC FLUSH/BACKWASH CYCLE WITH

RETURN TO OPERATING SERVICE, INITIATED BY TIME CLOCK, HIGH HEADLOSS, OR

MANUAL PUSHBUTTON.

10.) THREE LEVEL SWITCHES WITH DRY CONTACTS SHOULD BE PROVIDED BY THE

CUSTOMER AND INSTALLED IN THE FINISHED WATER STORAGE TANK FOR THE

AUTOMATIC OPERATION OF THE TRIDENT HS UNITS. ONE HIGH LEVEL SWITCH WILL STOP

THE UNITS, ONE MID LEVEL SWITCH WILL START THE UNITS AND ONE LOW LEVEL SWITCH

WILL SERVE AS A MINIMUM LEVEL TO ENABLE THE BACKWASH PROCESS.

11.) THE HIGH LEVEL STOP AND THE MID LEVEL START SWITCHES SHOULD BE INSTALLED

WITH SUFFICIENT VOLUME BETWEEN THEM TO PREVENT EXCESSIVE CYCLING OF THE

TRIDENT HS UNITS.

12.) THE LOW LEVEL BACKWASH ENABLE SWITCH SHOULD BE INSTALLED WHERE THE

MINIMUM VOLUME IN THE BACKWASH SUPPLY TANK IS ADEQUATE TO PROVIDE A

BACKWASH WITHOUT PULLING AIR INTO THE BACKWASH SUPPLY PUMP. THE MAXIMUM

WATER TEMPERATURE SHOULD BE CONSIDERED WHEN CALCULATING THE MINIMUM

BACKWASH VOLUME OR LEVEL IN THE TANK.

13.) AIRWASH BLOWERS ARE NOT SHOWN.

14.) AIR COMPRESSOR FOR VALVE OPERATION IS NOT SHOWN.

15.) AN AIR RELEASE VALVE IS REQUIRED AT HIGH POINTS OF ANY WATER SUPPLY LINE

(I.E. INFLUENT; BACKWASH) TO VENT ACCUMULATED AIR. THE VALVE(S) ARE TO BE SIZED

TO ALLOW THE COMPLETE VOLUME OF THE SUPPLY LINE FROM SOURCE TO UNIT, TO BE

VENTED IN 20 SECONDS WITH DIFFERENTIAL OF APPROXIMATELY 10 PSIG, AND BE

CAPABLE OF CONTINUOUSLY VENTING ACCUMULATED AIR (BY OTHERS). FOR

INSTALLATION UTILIZING VERTICAL TURBINE OR "CAN-TYPE" PUMPS, A SEPARATE

"TURBINE AIR VALVE" IS REQUIRED TO VENT THE AIR CONTENTS OF THE PUMPED

COLUMN WITHOUT LETTING THE AIR INTO THE SUPPLY PIPING (BY OTHERS).

16.) TANKS ARE FURNISHED WITH FINISH COATING SUITABLE FOR POTABLE WATER

APPLICATIONS ON INTERIOR; PRIMER ON EXTERIOR. TANK BASE PLATE BOTTOM IS

UNPAINTED FOR INSTALLATION ON COAL TAR OR ASPHALTIC TYPE BASE MASTIC

COMPOUND (BY OTHERS). TRIDENT HS UNITS SHOULD BE LEVEL WITHIN ONE EIGHTH

INCH IN TEN FEET AT TIME OF INSTALLATION.

17.) OPTIONAL EQUIPMENT TO SUIT PROJECT REQUIREMENTS IS AVAILABLE. TYPICAL

PROCESS EQUIPMENT OPTIONS INCLUDE: ADDITIONAL CHEMICAL FEED SYSTEMS,

INFLUENT TURBIDITY RECORDERS, INFLUENT STREAMING CURRENT MONITOR,

PLATFORM/WALKWAY CLIPS.

18.) CONSULT FACTORY FOR OTHER INFLUENT FLOW CONTROL OPTIONS.

19.) ALTERNATE CHEMICAL FEED SYSTEMS ARE AVAILABLE. CONSULT FACTORY FOR

RECOMMENDATIONS.

20.) ALL TANK FLANGED CONNECTIONS, EXCEPT OVERFLOW, EXTEND 6" FROM SHELL OF

TANK.

21.) LOCATION OF FLOW METERS ARE TO BE PER FLOWMETER MANUFACTURER'S

WRITTEN RECOMMENDATIONS CONFIRMED BY THE CONSULTING ENGINEER. GROUNDING

RINGS ARE BY OTHERS, IF REQUIRED.

22.) ELEVATION AND HEIGHT DIMENSIONS ARE CALCULATED FROM THE BOTTOM OF THE

TANK BASE PLATE.

23.) THE DESIGN BACKWASH RATE LISTED IS BASED ON A TEMPERATURE OF 25 DEGREES

CELSIUS. THE ACTUAL BACKWASH WATER RATE MUST BE ADJUSTED 2% UP OR DOWN

FOR EACH DEGREE CELSIUS DIFFERENCE ABOVE OR BELOW FROM DESIGN

TEMPERATURE; I.E. IF ABOVE 25°C, INCREASE BY 2%; IF BELOW 25°C, DECREASE BY 2%.
