Work-segments

  • Production of standard materials

  • Design of evaluated analytical procedures

  • Lab scale experiments

  • Pilot scale experiments

  • Full scale monitoring


TOXIC - EVK1-2001-00182

WP 1 - Co-ordination and Project Management

Participants:TZW

  • Protocols

  • Reports

  • Public presentations


TOXIC - EVK1-2001-00182

WP 2 - Raw Water Quality

Participants:UDU, TZW, AAU, UAL, ULO

  • Data base of cyanobacteria and cyanotoxins in European waterbodies

  • Establishment of an Internet-Based Platform on cyanobacteria and-toxins in European waterbodies (cyanobacteria-platform.com)

  • List of suitable methods for early-warning of cyanobacterial bloom


TOXIC - EVK1-2001-00182

WP 3 - Analysis

Participants: AAU, UDU, ULO

  • Supply of pure cyanotoxin standards

  • Know-how transfer andinter-calibrationexercises

  • Provision of Standard OperationalPrecedures(SOPs) for cyanotoxin analysis (PPIA, ELISA, HPLC/UV, MS)


TOXIC - EVK1-2001-00182

WP 4 - Conventional Treatment

Participants:TZW, UDU, DHI, UEX, UAL, ULO

  • Test of different treatment trains

  • Cyanotoxin biodegradability and degradation kinetics (aerobic and anaerobic)

  • Risk assessment for treatment trains (intra- and extracellular toxins)


Toxin release - pilot plant studies


TOXIC - EVK1-2001-00182

WP 5 - Polishing Treatment: activated carbon

  • The application of activated carbon (PAC !!!) is one of the most efficient measure for dissolved toxin removal


The efficiency of activated carbon

dichloroethene

trichloroethene

atrazine

MCYST-LR

Activated carbon in mg/L


TOXIC - EVK1-2001-00182

WP 5+6 - Polishing and Final Treatment:

oxidation and disinfection

  • Kinetic data base for oxidation of cyanotoxins by oxidants (chlorine, chlor-amine, chlorine dioxide, permanganate, ozone)

  • Assessment of the influence of water qualityparameters (DOC, alkalinity, pH, temperature, ammonia) on toxin oxidation

Participants:EAWAG, UEX, WRc, UAL, ULO

Case studies


TOXIC - EVK1-2001-00182

Case study I: pilote scale


TOXIC - EVK1-2001-00182

Case study II: pilote scale


TOXIC - EVK1-2001-00182

Case study III: pilote scale

Conclusions

  • Toxin removal (cell bound and dissolved) with high efficiency is possible !!!

  • The non calculable risk is the toxin release – an efficient additional barrier is the use of activated carbon.
