AppliTek Ra-TOX - On-line Toxicity Analyzer

The Ra-TOX On-line Toxicity Analyzer has been designed to detect acute toxic effects of incoming waste water streams of waste water treatment plants. The technology as incorporated is based on the respiration rate (expressed as mg O2/l.h), one of the most important parameters for the biological activity of activated sludge. The Ra-TOX respiration module measures every minute the respiration rate of the sludge/water mixture in the analyzer batch vessel, comparing it with a calculated moving average of the respiration rate, the reference value. In case the difference is larger than a preset alarm level, an alarm output is activated.

The unique design of the Ra-TOX On-line Toxicity Analyzer overcomes the disadvantages of other analyzer concepts using two oxygen sensors. Instead, the respiration rate measurement used is a patented technology using a single DO-electrode. The respiration technology as applied is also available in the at-line analyzer Ra-COMBO for determining BODst or toxicity (see Options / Extra below).

Patented Respiration Technology

  • Continuous use of real sludge from WWTP for measurement - ongoing measurement EVEN during toxicity events
  • Measurement at same pH as WWTP
  • Measurement at same temperature as WWTP
  • Fast response (typically 5 min.)
  • Field proven technology

General Features

  • Human interface: 10.4' color touch screen with excellent viewing angle and graphics. Can remotely be taken over by LAN ethernet software (VNC).
  • Visualization of toxicity events and respiration activity in real-time
  • Standard auto-cleaning
  • First class and robust moving components such as low-speed peristaltic pumps and patented single O2 electrode Respiration Module
  • Incorporated industrial PC with result & alarm data export (1000 results including sample stream, date, time)
  • Multifunctional sealed USB port on left side of the housing (result download, program upload, reporting)
  • Communication: active 4 - 20 mA, Ethernet, RS232, TCP-IP
  • Weight: 65 kg (144 lbs.)

Options / Extra

Sludge and waste water should be sampled in fast loop; please check the detailed section on this.

This system is also available as a laboratory desktop at-line analyzer. Please check our laboratory product portfolio.

APPLICATIONS

Water Analyzing for the Mining Industry

As a primary industry, the mining industry faces the needs for optimizing the management of its resources. Exploration and excavation activities should be as efficient as possible. Companies also aim to maintain water resources while at the same time controlling the environmental impact of their activities. As pioneers in exotic mining analytics, AppliTek can help you with a selection of application-oriented analyzers, from portable XRF systems to on-line analyzers for water and process applications.

Water Monitoring for the Pulp & Paper Industry

In the field of quality control and process control, AppliTek has developed a unique set of specific monitoring solutions in order to meet the ever-increasing demand for cost efficient paper production. Traditionally, AppliTek is also your one-stop shop for on-line analyzers with regards to environmental compliance.

Environmental Control for the Water Utility Industry

This section contains applications relevant for compliance, water treatment, drinking water and natural sources.

Collecting, treating and distributing water to consumers and industry, in compliance with quality standards, means a challenging task to water companies. Both private as public water treatment entities have to manage carefully and sustainably their sources, processes and even distribution networks. AppliTek supports them not only with an extended portfolio of analyzers but also with its...

Online Monitoring for the Wastewater Treatment Industry

AppliTek`s large portfolio of on-line analyzers enables you to monitor precisely the complete treatment process, from influent to effluent. Compliance with discharge regulations is another application example and typically expressed as sum parameters, for which AppliTek has unique solutions.

Real-time Control System for Wastewater Treatment Plants

Wastewater treatment plants (WWTP) are subject to large variation in flow and load, not to speak of uncertainties on the composition of the incoming wastewater. On top of that, the activated sludge treatment process, as used by the vast majority of treatment plants, is difficult to control due to the complex behaviour of the biological process. Nevertheless WWTPs are run 24/7, with operators and management challenged to meet ever tightening environmental regulations.

In order to meet the operational...
