Online Analyzers: EZ Series Analysers
EZ Series Volatile Fatty Acids Analysers
EZ Series Volatile Fatty Acids Analysers
- Overview
- Downloads
The EZ Series Online Analysers offer multiple options to monitor Volatile Fatty Acids in water. Applications are anaerobic wastewater treatment, anaerobic sludge treatment and pilot scale anaerobic reactors.
Volatile fatty acids are important intermediate products for the methanogenesis. They affect loading, efficiency and operational stability of the process. An accumulation of VFA is toxic to bacterial cultures due to inevitable pH drop, especially for the methanogenic bacteria which are only active in a narrow pH range.
The EZ7200 Series VFA Analysers are single-parameter titrators designed specifically for monitoring (wet) anaerobic digesters.
- EZ7200 VFAs, 10 - 500 mg/L as acetate equivalent
- EZ7201 VFAs, 20 - 1,000 mg/L as acetate equivalent
- EZ7202 VFAs, 100 - 5,000 mg/L as acetate equivalent
- EZ7203 VFAs, 500 - 10,000 mg/L as acetate equivalent
- EZ7250 VFAs, 10 - 500 mg/L as acetate equivalent, total and partial alkalinity 50 - 2,500 mg/L as CaCO3
- EZ7251 VFAs, 20 - 1,000 mg/L as acetate equivalent, total and partial alkalinity 50 - 2,500 mg/L as CaCO3
- EZ7252 VFAs 100 - 5,000 mg/L as acetate equivalent, total and partial alkalinity 250 - 5,000 mg/L as CaCO3
- EZ7253 VFAs 500 - 10,000 mg/L as acetate equivalent, total and partial alkalinity 250 - 5,000 mg/L as CaCO3
Options for all analysers include:
- Multiple stream analysis (1-8 streams) reducing cost per sampling point
- Analogue and/or digital outputs for communication
Most applications require the use of an EZ9130 sampling/filtration system for sample preconditioning. For this option please check the EZ9000 Sample Preconditioning page.
