Toxicity

ToxSys
On-line and laboratory analysis techniques

Broad band toxicity detection for intake protection, WWTP control, final effluent consent or drinking water applications- differing techniques are appropiate for differing applications:

  • Sensitive monitoring for toxicity for river water
  • Detection of water intakes - even against malicious attacks - appropiate detection at required sensitivity
  • WWTP intake for biomass protection - adaption needed to reproduce plant biomass response
  • WWTP outlet for watercourse / sewer toxicity measurement - immoblised biomass preferable due to lack of access to local WWTP

Deciding which toxicity method or analyser is suitable for your application - factors to consider are:

  • Sensitivity needed
  • Biologically adapted or non- adapted & ease of access to local biomass ?
  • Ease of use / running costs
  • Toxic detection of which compound
