 This quarter, Dr. Tom has assembled a collection of DYNAC® ES tips and tricks to help operators more efficiently manage their control systems. Did you know:
-
DYNAC® now includes a module that allows polling
of all SNMP (simple network management protocol) enabled network
devices. SNMP status information can be used to create dynamic displays
of the entire network including connections between devices. Network
switches can be monitored down to the port level and system alarms generated on
port or connected device failure. This feature expedites diagnostic and
repair cycles by allowing maintenance personnel to pinpoint network equipment
failures.
-
The new DYNAC® Microsoft Excel plug-in provides
direct access to system historical records. This application increases
availability of data access across the enterprise by allowing access to
historical files in standard Excel format. Users are then able to
harness the familiar functions and features of Excel to manipulate and present
the historical data. Report generation is simplified via the use of
predefined report templates. This feature allows system users to select
one or more data points from a graphical display and then right-click on a
template definition. An Excel report is then automatically generated that
includes historical data for the selected points covering the time frame and
data ranges defined by the template.
-
The DYNAC® Manual Data Entry Application enables more efficient
and accurate reporting of manually collected data. Transdyn developed this
application in response to feedback from our environmental clients, although
its capabilities are applicable to all of our markets. These clients are
required to submit monthly reports to state environmental protection agencies.
The majority of the data used to develop these reports is derived from the
DYNAC® historical database but manually collected lab data is also
required. Historically, this process involved lab technicians manually
recording lab samples on printed forms followed by operations supervisors
re-entering the data into spreadsheets for month-end reporting. This
process was both time consuming and error prone. The Manual Data Entry
application allows lab technicians to enter, validate and submit their
measurements directly to DYNAC® database. This data is then accessible to the
enterprise for reporting via the Excel plug-in.
- A
complete suite of DYNAC® conversion programs is available to convert all aspects
of OS64 to ES including Dataviews graphics, links, layers and point dynamics.

Lanier Water Treatment Plant: An Integrated Approach to Ozone Process Control
Owner: Gwinnett County Department of Water Resources
Location: Buford, GA
|
Gwinnett County Department of Water Resources (DWR) has been
operating ozone disinfection systems at their Lanier and Shoal Creek water
treatment facilities for over 14 years.
The original control strategies at both facilities envisioned three
methods of control; 1) manual, 2) automatic based on influent flow pacing, or
3) automatic using ozone residual feedback, also known as CT Trim. Though feasible strategies for control, the
available gas flow control valves and analytical instruments were unable to
provide reliable gas flow adjustment and accurate residual feedback.
As a result, both auto modes failed to produce predictable
disinfection results. To meet mandated
disinfection guidelines, the DWR manually operated the ozone system by
adjusting ozone feed rates based on periodic wet lab samples. The lack of reliable, real-time residual
feedback forced DWR to dose conservatively to ensure a safe disinfection level
resulting in increased power consumption, liquid oxygen usage, and operational
labor. Though inefficient, it allowed
DWR to develop an in-depth knowledge of their ozone system and the required
modifications to the control strategies and analytical instruments necessary to
achieve their ultimate goals of process efficiency, energy savings, and safe
disinfection practices.
Over time, the County was able to acquire, install and
maintain reliable process control equipment and instruments, but associated
changes to the process control logic performed by the Ozone System Supplier
proved to be challenging. Though a
typical ozone system delivery method, the County preferred that their local Systems
Integrator assume responsibility for overall ozone system control to achieve
the desired results, ensure operational consistency and facilitate
comprehensive system support.
In 2007, an extensive upgrade of the ozone process at the
Lanier plant was designed by CH2M Hill.
The scope included the complete replacement of two of the three existing
ozone generators, two destruct units, their associated controls and associated
physical process changes. Starting from
a base concept of operation, Transdyn, the County's Systems Integrator, Ozonia,
the Ozone system supplier, and DWR worked together to develop a process control
narrative consistent with the County’s enhanced operational objectives. The ozone control system included a redundant
master control processor networked to local control processors located at each
generator and destruct unit. Ozonia
programmed the local processors while Transdyn developed the control logic in
the master control processor and integrated the new ozone system into the plant
automation system. This division of
responsibility allowed each party to focus on their core competency and
provided the County with the assurance that the process control domain
expertise resided with their Systems Integrator.
The County's vision was realized in 2009 when the system was
successfully placed into service. Though
the County primarily uses the CT Trim mode of operation, both automatic modes
have proved reliable. The new control
strategies have increased operational efficiency resulting in reduced
cost. The shift of system control
responsibility from the ozone system supplier to the Systems Integrator has
allowed for more effective performance, maintainability, and reliability.
