Using air instead of biogas for mixing and its effect on

Dec 01, 2020 · The results indicated that the methane production for air mixing was increased by 6.4%, 11.9% and 19.6% compared with biogas mixing, mechanical mixing and no mixing. Air mixing improved the mass transfer and the homogeneous mixing time was shortened from 10 min of mechanical mixing to 1.5 min at the same power input.

SMART PUMP SYSTEMS FOR MIXING OF BIOGAS REACTORS

hydraulic mixing of biogas reactors, testing it under practical conditions. The pump technology was designed to feed and mix the reactor. This is achieved by suspending the feed, for example straw and solid manure, with the fermenter contents and returning this mixture back into the biogas reactor with high hydraulic intensity.

Digester Mixing Fundamentals | BioCycle

The Landia model POP-I 360 is an extremely durable mixer, which is widely used for mixing liquids with high dry matter contents in biogas plants. It is particularly suitable for mixing receiving tanks, which require fast and effective homogenization of feedstocks prior to entering the anaerobic digester.

Putting a Biogas Digester Solution to Work - Pumps

In the first stage of the mixing process, the liquid will be injected into the upper half of the tank, while biogas is aspirated from the top of the tank and mixed into the liquid. This not only has the benefit of reducing buoyancy at the surface of the liquid, but also continues to mix after the pumps are switched off thanks to the rising gas

Effect of mixing on biogas production during mesophilic

Apr 19, 2011 · The effect of mixing on biogas production of a 1.5‐m 3 pilot continuous stirred tank reactor (CSTR) processing screened dairy manure was evaluated. Mixing was carried out by recirculation of reactor content with a mono pump. The experiment was conducted at a controlled temperature of 37±1°C and hydraulic retention times (HRTs) of 20 and 10 days.

Biogas from Manure - Penn State Extension

Mar 05, 2012 · The gutter cleaners deliver the manure from the barn to the slurry preparation area. The manure drops into the pump hopper with enough water to reduce the solids content from about 15 percent to 13 percent. The manure must be diluted to prevent clogging in pipes and pumps, and to ease mixing within the digester.

Anaerobic digestion of animal waste: effect of mixing

These systems rely on larger horsepower pumps than most other mixer types. This type of mixing on a waste-to-energy system can negate the benefit of additional biogas produced in a well-mixed digester. Intermittent mixing by shutting the pumps off can save energy, but it can exacerbate the RVE issues described earlier. Linear Motion Mixing
