Greeley Water Pollution Control Facility Blower
<br />Replacement I City of Greeley I Greeley, Colorado
<br />Lead I&C Engineer
<br />Sanki led the I&C design and commissioning of the
<br />upgrade of an existing aeration system to include an
<br />optimized automated control approach. Design
<br />included the integration of three new high-speed turbo
<br />(HST) blowers through the development of a
<br />consolidated control strategy for blower operation,
<br />while upgrading the end -of -life Allen-Bradley PLC
<br />hardware, Sankt witnessed factory acceptance testing
<br />of both hardware and software control system
<br />components and was solely responsible for on -site
<br />startup and commissioning, performing installation
<br />verification walk -downs, loop checks, process start-up
<br />and PID tuning, and operator training. Controlled
<br />processes included three 300-HP HST blowers, three
<br />K-Turbo blowers, two multistage blower skids, and
<br />four aeration basins.
<br />Support Facilities Upgrade I City of Denver
<br />Denver, Colorado I Lead I&C Engineer
<br />Sanki was lead 1&C engineer on the upgrade of the
<br />existing facility network infrastructure, including three
<br />facility buildings, and installing a new redundant data
<br />center. Design included upgrading the fiber network
<br />infrastructure to support a ring topology, coordinating
<br />the decommissioning of the existing data center and
<br />fiber network through detailed construction
<br />sequencing documents, Sanki developed the
<br />electrical cable tray layouts/isometrics, cable
<br />schedules, electrical plan drawings, and electrical
<br />specifications, He also designed a new CCTV
<br />intercom and access control system with integration
<br />into the plant -wide network,

<br />Program Phase I I Colorado Springs Utilities
<br />Colorado Springs, Colorado I Lead I&C Engineer
<br />Sank! created P&IDs, specifications, instrument lists,
<br />network diagrams, datasheets, and technical
<br />memorandums, in addition managing and
<br />coordinating drawing production resources.
<br />Controlled processes included rapid mixing,
<br />Flocculation, sedimentation, and chemical and
<br />polymer systems. The control system was exclusively
<br />based on the Rockwell product line, including Allen
<br />Bradley smart MCCs, Logix controllers, FactoryTalk
<br />HMI, and OSI PI historian with Ethernet/IP profibus
<br />field network.
<br />Nuisance Struvite and Dewaterability Improvements
<br />PAR 1280 1 Metro Wastewater Reclamation District
<br />Denver, Colorado I Lead I&C Engineer
<br />Sanki is leading the design of an AirPrexTM pre-
<br />dewatering phosphorus recovery system to sequester
<br />and recover phosphorus as struvite. The process
<br />reduces the phosphorus load recycled to the head of
<br />the plant, facilitating controlled precipitation of struvite
<br />to reduce the potential for nuisance accumulation
<br />within pipelines, and improve biosolids dewatering.
<br />Phase I included the pre -procurement of vendor
<br />blower and classifier packages and associated
<br />instrumentation. Phase 11 integrates the pre -procured
<br />packages to the existing DCS. Controlled processes
<br />include recovery reactor, aeration system, anti -foam,
<br />and magnesium chloride storage and dosing systems,
<br />Sidestream Nutrient Removal Project PAR 1237 1
<br />Metro Wastewater Reclamation District
<br />Denver, Colorado I Lead I&C Engineer
<br />Sankt was lead I&C engineer on the upgrade of an
<br />existing facility involving enhanced biological
<br />phosphorus removal (EBPR) and de-ammonification
<br />(DMX) treatment. He created P&IDs and coordinated
<br />vendor designs, specifications, instrument lists,
<br />network diagrams, datasheets, and technical
<br />memoranda, Controlled processes included
<br />ANITAMox DMX reactors, EBPR, and chemical
<br />systems. Facility controls used an ABB DCS
<br />control system.
<br />CCWRF 12kV Backup Generator Control Circuit
<br />Improvements I Inland Empire Utilities Agency (IEUA)
<br />Chino, California I Lead I&C Engineer
<br />Sankt is upgrading the existing, relay -based
<br />Automatic Transfer Control system to a new,
<br />redundant PLC -based control system according to
<br />IEUNs Engineering Design Guidelines, while
<br />addressing Agency stakeholder concerns,
<br />19007 Aeration and Secondary Clarifiers (150-MGD
<br />Expansion) I Clark County Water Reclamation District
<br />Las Vegas, Nevada ILead l&C Engineer
<br />Sankt is the lead I&C engineer for the upgrade and
<br />capacity expansion (to 150mgd) of the west
<br />secondary treatment facility, including three aeration
<br />basins, three secondary clarifiers, four dual core
<br />High -Speed Turbocompressor (HST) blowers, MLR,
<br />WAS and RAS pumping systems to support biological
<br />nutrient removal, including nitrification, partial
<br />denitrifcation, and biological phosphorus removal.
<br />The project is being executed under a Construction
<br />Manager At -Risk (CMAR) alternative delivery
<br />approach, The control system includes Rockwell
<br />ControlLogic PLC and Remote 1/0 with AVEVA
<br />(WonderWare) InTouch SCADA System,
