DataNet – Delivers a Single View of Complex Parallel Processes


Customer’s Last Word:
“With the DataNet system we’ve been able to streamline our treatment process to use minimal chemical and energy reserves.”
INPISA Representative

As an EU member state, Spain has enacted national legislation to achieve compliance with EU requirements for the treatment of municipal and industrial waste waters. Treatment plants also face great pressure to work as effectively, reliably and efficiently as possible to respond to the increasing pressure on water resources. 

Application: Waste Water Treatment  

Organization: INSPRISA, Spain

Background:
As an EU member state, Spain has enacted national legislation to achieve compliance with EU requirements for the treatment of municipal and industrial waste waters. Treatment plants also face great pressure to work as effectively, reliably and efficiently as possible to respond to the increasing pressure on water resources.

About the Customer:
Founded in 1992, INPRISA is a Spanish company that specializes in wastewater treatment.
INPRISA uses a series of waste water treatment processes including ion exchange, ultra-filtration, reverse osmosis, physio-chemical purification, filter presses, chrome recovery, evaporators and acid reclamation.

Key Customer Challenges:

  • Precipitating out toxic materials from water requires treatment with a number of chemicals and constant pH, flow-rate, conductivity and temperature data to be recorded in a single module, determining the relationships between them.
  • National and international guidelines for waste water directives demand full reports of treatment processes that satisfy administrative and also legal requirements. Data history must be detailed enough to establish how much wastewater received primary and secondary treatments, or nutrient reductions.
  • In every treatment plant, the company needs to know where chemicals and energy are most used throughout the process, in the hope of pinpointing areas for savings. 


DataNet Implementation:
The installation comprises three DataNet DNL910 loggers, one repeater and one receiver monitor, as well as pH, conductivity and flow probes. The DataNet logger units are placed with pH and conductivity sensors in large waste-water basins, as well as in a pipe where flow is measured. The logger and sensor installation is located 200 meters from the receiver, which is located in the control room with a repeater for optimal transmission. The readings required range from pH 6-8 values, up to conductivity 800 uS/cm and flow 2.000 m3 /h and data is transmitted to the central computer every 15 minutes. Alarms when data crosses the pre-defined parameters are sent to the control room, and SMS alerts can also be applied, allowing technicians to immediately address issues that arise. Regularly the data is exported to Excel and spreadsheet reports produced for the Council of Water Control and Administration, to demonstrate adherence to water policy standards. INPRISA now offer the system as standard in all water processing installations


Measurable Results:

  • Unified data values presentation – for easily managed data from multiple channels, indicating the different treatment elements that occur simultaneously and allowing the entire water treatment system process to be evaluated for inefficiencies. 
  • Effective trouble shooting  – protected data and reliable alerts. In the event of transmission loss, data is recorded and stored in the logger memory, as well as the network finding an alternative data transfer route. In the case of any malfunction during part of treatment system, the SMS alerts alarm system is applied.
  • Generating Detailed Reports– customized to meet governmental waste water guidelines, the reports provide INPRISA clients with clear and comprehensive documents for regular submission to the local and EU authorities.
  • Chemical and energy conservation – create a clear picture of the dynamics of the waste water treatment procedure, and spot inefficiencies in the system
  • Flexibility in a single system – not only  performing well as a temperature control monitoring tool, but also for process measurements, a single inexpensive transmitter with 4/20 mA, can obtain data and display in table or graph form, as well as indicate minimum and maximum values.
