Analyzers, Process Controllers & SCADA

Analyzers, Process Controllers and SCADA (Supervisory Control And Data Acquisition)

SCADA System
Pure Elements SCADA system is a computer and communications equipment designed for the purpose of controlling and monitoring water and wasterwater treatment processes. Our SCADA application performs data logging, alarming, monitoring and diagnostic functions so that enoormous, complicated process systems can be operated safely and maintained by trained operators.

SCADA system panel features:

Input/output modules in analog and digital connection
Store and retrieve data logging information
Track water levels in large reservoirs and tanks
Control water production
Measure water pressure per square inch (psi) to ensure that water is pumped and flowing efficiently
Data logging of chlorine, pH, turbidity, water temperature, flow (Q-peak) and reservoir volume
Sustain and reduce pressure and other valves that open and close incrementally
Capable of running standard control algorithms for maintaining tank levels, flow rates and processes at specific temperatures and pressures
PC based system with programmable scripting language for processing information and communication

Chlorine Analyzer
Chlorine Residual Analyzer utilizes the most accurate test method to determine chlorine residual levels in process waters, similar to that used in lab environment titrator test methods, which is good for chlorine control or monitoring applications. Residual readings are instantaneous and do not rely on “sample and hold” methods. This minimizes any delay in readings for control applications. The continuous 4-20 milliamp output signal can be used to drive chlorine residual control systems and/or chart recorders or SCADA systems. The alarm outputs can alert plant operators to an out-of-range chlorine residual, or trigger an autodialer in remote or off-hour situations.

The analyzer is designed to be relatively maintenancefree, other than adding vinegar when it runs out. The use of vinegar as a pH buffer is simple, effective, economical, and environmentally friendly. Converting the analyzer to read total chlorine, is as simple as adding Potassium Iodide to the vinegar buffer.

Analyzer features:

Continuous, isolated, 4-20 milliamp output signal, suitable for control or monitoring applications
Measures free or total chlorine residuals
Applications include fresh water, wastewater and food processing
Simple to calibrate and operate
Uses inexpensive, non-toxic, foodgrade vinegar for pH buffering
Built-in high and low alarm relays
Field-adjustable range
High range capabilities to 60 PPM without dilution

Process Controllers
Process control helps SCADA to record and process data that are converted into information for water treatment solutions. This system involves process data analaysis to improve process performance. Process control uses a PC machine and a spreadsheet program like Microsoft Excel to analyze processed data. A lack of process control and inadequate trained operators leads to faulty design water and wastewater applications. At Pure Elements, we use our hands-on experience to design effective process controllers.

Process Controllers features:

Decrease operational cost for chemical and power consumption
Dynamic operation by improving process dynamics
Maintain efficient water and wastewater treatment plant performance
Increase the amount of water and wastewater that can be treated per unit process volume
Trained operators for efficient operations
Improved Health, Safety and Environment (HSE) management system
