Iron removal in highly contaminated acid mine drainage using passive biochemical reactors

Passive biochemical reactors (PBRs) are a viable alternative to neutralization plants for the treatment of acid mine drainage (AMD) because they require lower investment costs and use residual materials. However, high iron (Fe) concentrations (≥0.5 g/L) in AMD are challenging for their long-term efficiency. Sorption and precipitation are the main Fe removal mechanisms, but the relative ...

Preparation of slow-releasing oxygen materials and study on their properties

Slow-releasing oxygen materials were prepared to overcome some limitations regarding the low dissolved oxygen (DO) concentration and the low efficiency of in-situ purification in groundwater. ...

Release of NEW Small Diameter pH and Conductivity Probes

These new electrodes are fully compatible with MANTECH’s MT Automated Environmental Titration Systems and can be swapped in place of existing electrodes. With diameters of 5mm (Conductivity) and 6mm (pH), the sample volume required for ...

pH & Temperature Vial

Based on the contactless sensor technology, PyroScience offers ready assembled vials with integrated sensor stripes for all supported analytes. The glass respiration vials have screw caps with a septum, and are available with ca. 20mL (uncalibrated) volume. Adapter rings allow an easy fixation of optical fibers for read-out with optical meters from PyroScience for incubations in closed vials. The ...
