The anaerobic process is a relatively
simple process that utilizes bacteria in the absence of oxygen to break
down organic materials. As the organic material breaks down, it
generates biogas with a 50-60% methane content. This gas can be utilized
to power an engine/generator system, fire a boiler, or simply flared.
The key aspects of selecting an
Anaerobic Digestion System that will maximize the biogas production,
operate reliably, justify the investement and be simple to maintain are
proper selection of a proven technology, proper integration of the
various components, and utilizing an engine that is specifically
designed to operate on biogas.
The digester technology utilizes a
modular, stainless steel, bolted, above ground, insulated tank. The roof
consists of a dual membrane system to provide constant gas pressure
with an integral hydrogen sulfide scrubbing system to protect the
The engine/generator system utilizes
an engine specifically designed to operate on biogas. The system also
includes a coalescing unit, gas regulation system, and heat
A key component of the system is
an automation package that incorporates all the operating parameters of
the digester system along with the engine/generation system.
Incorporating these components with the turn-key installation provided
by Clear Horizons maximizes the reliability of the system and ensures it
meets its projected operating parameters.
Clear Horizons is the first in
Wisconsin to offer an electrical intallation that is state certified to
meet electrical building codes as well as the explosion-proof safety
standards for biogas systems.
