Waste Treatment OverviewWaste Treatment Overview
A simple view of a typical Waste Water Processing System
Pumping and Lift StationsPumping and Lift Stations
Moving waste to the plant for processing
• Wet Well or Dry Well may be considered a confined space
• Combustible Gas• Oxygen Depletion• Hydrogen Sulfide• Sensors must be mounted
above high water mark

The HeadworksThe Headworks
Where it all begins• Large debris removal• Rakes and Bar Screens
Gas Detection Required• Combustible Gas Cat-Bead
– Combustible Liquids
– Heavy Hydrocarbons
• Combustible Gas Infrared– Methane or Light Hydrocarbons
• Oxygen Depletion• Hydrogen Sulfide
Influent ScreeningInfluent Screening
• Bar Screen Rooms• Sedimentation Tanks• Grit Chambers• Solids Transport and
Loading
Gas Detection Required• Combustible Gas Cat-Bead
– Combustible Liquids
– Heavy Hydrocarbons
• Combustible Gas Infrared– Methane or Light Hydrocarbons
• Oxygen Depletion• Hydrogen Sulfide
Sludge ProcessingSludge Processing
• Sludge Storage Tanks• Gravity Thickeners• Pumping Systems• Sludge Dewatering• Sludge Incineration
Gas Detection Required• Combustible Gas Infrared
– Methane or Light Hydrocarbons
• Oxygen Depletion• Hydrogen Sulfide• Carbon Monoxide
ClarificationClarification
Secondary Treatment
Bio-Solids settling and removal
Gas Detection Required• Combustible Gas Infrared
– Methane or Light Hydrocarbons
• Hydrogen Sulfide (Odor Control)
DigestionDigestion
Aerobic Digestion (With Air)
Anaerobic Digestion (Without Air)
Combustible Gas IR (Methane)Used for Co-Generation
Sold to Gas Company
Hydrogen Sulfide (Odor Control)
Final DisinfectionFinal Disinfection
Final point before discharge into local River, Lake or Creek.
Gas Detection Required• Chlorine• Ammonia• Sulfur Dioxide
Equipment SelectionEquipment Selection
• Sierra Monitor New IT series positioned for the future
• IT series modules meet both NEMA 7 and NEMA 4 rating
• IT series modules meet both Analog 4-20 mA and Digital protocol requirements
• Use of Rainshields allow for remote calibration
• Promote Infrared durability and cost of ownership

Recent SuccessesRecent Successes
• City of New York DEP (Wards Island Plant)– A&E = Malcolm Pirnie– Contractor = P.J.S. Electrical– 120 + Points of Combustible & H2S
• City of Cleveland, Ohio (Easterly, Southerly, Westerly)– A&E = Malcolm Pirnie (PA-3)– Contractor = Bay Mechanical & Electrical– 80 + points Combustible & H2S– A&E = Montgomery, Watson, Harza (HEI-1)– Contractor = Shook Northern Construction– 50 + Points of Combustibles
Where to beginWhere to begin
• Architect & Engineering firms– Find Projects– Get into specs – “locked-in” or “equal”– A&E’s must account for their time so best access:
• Lunch & Learns considered continuing education and we do them often. Schedule at least one per quarter.
• Specific project meetings
• Investment– A&E Calls are not instant revenue generation they are investments in future projects– Involve RSM’s in A&E calls
Where to winWhere to win
• Relationships with local contractors a must– Monitor local municipal project awards– Follow the chain of funds– Some Electrical & Mechanical contractors will
consistently win municipal bids • Find them – get to know them – visit them often
– Municipal work is LOW BID• We win by: Installation efficiency, aggressive pricing
when necessary– Sierra Monitor’s submittals are the best available – use
examples to create high confidence with new contractors
