About Aerobic Digester

Aerobic Digester

Aerobic Digester consists of a 2 gallon reactor vessel mounted on a steel base, with a liquid feed pump, air supply, and instrumentation for monitoring and controlling the process.
The cylindrical wall of the reactor is made from 2 layers of porous plastic material to retain the suspended solids, while allowing treated water to pass through to the outer, annular exit chamber.
This design allows the essential features of the aerobic treatment process to be studied without the distractions of having to settle the solids adequately enough for external recycle, a well known laboratory problem.
The porous liners are removable for cleaning, and a spare liner is supplied.
Waste water is drawn from a feed tank by a 120V motor driven peristaltic pump. Flow rate is controlled by a variabe run time control that determines the minutes of run time within a 10 minute cycle.
The pump delivers the feed to the reactor vessel through a transparent lid. Air is supplied at a measured rate by a small air pump, and discharges into the base of the reactor via an air distribution device.
This provides the necessary oxygen for the digestion process, as well as produces sufficient bubbling for stirring and reaction.
The liquid level in the reactor is maintained at a constant value of 1 or 2 gal. by an overflow device connected to the outer annular chamber of the vessel. Discharge is by gravity to a floor-standing product tank (not supplied).

The reactor temperature is maintained by a 3-term PID controller which varies power to an immersion heater within the vessel. Any temperature between ambient and 95F may be selected, with the best conditions being a few degrees above the diurnal maximum in the users laboratory.

Dissolved oxygen and pH probes and meters are included.
The reactor lid contains a gas exit port, suitable for sampling the gases for subsequent analysis

Robust Stainless Steel Construction

Engineered for longevity, the Aerobic Digester uses high-grade Stainless Steel 304, offering excellent resistance to chemicals and corrosion. This design allows for easy cleaning and minimal maintenance, making the unit ideal for continuous laboratory use in chemical engineering applications.

Efficient Mechanical Agitation and Aeration

The integrated mechanical agitator maintains uniform mixing, while the air diffuser system optimally supplies aeration needed for the aerobic digestion process. Adjustable stirring speed and digital controls create a precise, repeatable testing environment suitable for diverse specimen sizes and volumes.

Advanced Safety Features and User Interface

Equipped with overload protection, safety cutoff, and an accessible viewing window, this digester prioritizes operator safety and convenience. Its digital display and manual override offer flexible control, while real-time measurement ensures accurate, responsive results. The inclusion of an RS232 interface supports data acquisition and reporting.

FAQs of Aerobic Digester:

Q: How does the mechanical agitator enhance the aerobic digestion process?

A: The mechanical agitator ensures consistent mixing of the specimen, promoting optimal contact between air supplied through the diffuser and the material. This results in efficient aerobic digestion by maximizing oxygen transfer and bacterial activity.

Q: What are the benefits of the Stainless Steel 304 construction for laboratory use?

A: Stainless Steel 304 offers superior chemical resistance and durability, which is essential for laboratory environments. It prevents corrosion and simplifies cleaning, ensuring reliable operation and extended equipment lifespan.

Q: When should the overload protection and safety cutoff features be used?

A: These safety features automatically activate in case of mechanical or electrical overload, protecting both the equipment and operator. Routine use during each operation ensures safe handling and prevents accidental damage.

Q: Where is the Aerobic Digester best installed within a laboratory setting?

A: Its compact, table-top design allows flexible placement in any chemical engineering laboratory workspace. Positioning near ventilation and power supply ensures safe operation and convenience during experiments.

Q: What is the process for monitoring specimen conditions during testing?

A: The provided viewing window allows direct observation of test progress, while the digital display delivers real-time data on volume, stirring speed, and temperature. This enables precise monitoring and control throughout aerobic digestion trials.

Q: How can the stirring speed and test stroke be adjusted for different experiments?

A: Stirring speed (50250 RPM) and test stroke (up to 200 mm) are easily set using the panel controls or digital interface, accommodating a variety of specimen sizes and experimental requirements to optimize digestion efficiency.

Q: What advantages does quick delivery and ready stock offer to laboratory users?

A: Quick delivery ensures timely support for ongoing laboratory projects or urgent requirements, minimizing downtime. Ready stock availability also facilitates prompt replacement, expansion, or setup in research and educational environments.
