One of the major benefits provided by this technology is substantial reduction in sulfur‐containing odors. Based on years of successful treatment controlling sulfide odors, the goal of this testing was to determine the potential for utilizing MICROBE-LIFT® technology in biofilters to improve removal of sulfur-containing odors in a wide ...
To determine the mechanism of DON increase, DON and other related parameters at different media depths of the biofilter were studied. The results showed that the DON concentration in the biofilter presented a rapid decrease from 0.73 to 0.44 mg l−1 in the top media (0–10 cm), and a slow increase from 0.44 to 1.08 mg l−1 in the bottom media (10–100 cm). Soluble ...
The system employs an initial unsaturated vertical flow biofilter with expanded clay media (nitrification), followed in series by a horizontal saturated biofilter for denitrification containing elemental sulfur media as electron donor. ...
The organics removal performance of a lab-scale aerobic biofilter of volume 0.6 L was studied using synthetic wastewater and waste automobile tyre-tube beads as media. The column study was performed under Chemical Oxygen Demand (COD) in the range of 500-1500 mg/L at an empty bed contact time (EBCT) of 2 h. The treatability constant at 27°C was found to be 41.963. A maximum COD removal efficiency ...
This study evaluated two biofilter designs to mitigate methane emissions from landfill vents. Water-spreading biofilters were designed to use the capillarity of coarse sand overlain by a finer sand to increase the active depth for methane oxidation. Compost biofilters consisted of 238-L barrels containing a 1: 1 mixture (by ...
Advantages Reduction of passive smell burden to 3-10% Cost-efficient even for de-central systems <6,500 Mg/a Reduced rot times Independent of turning system Operating costs savings through lower shift requirements Independent of pit shape (trapezoid, triangular, or board pit) Suction air burdened with smell is cleaned through biowashers and biofilters System ...
