Auger Monster FAQ

You Asked, We Answered

The Auger Monster® is one of our more robust and affordable wastewater screens. This Monster has been dubbed our triple threat as it combines three of JWC’s proven technologies – a grinder, a finescreen and a compactor. The Auger Monster helps treatment plants run more efficiently and makes life easier for operators and managers by pre-conditioning, screening, removing, and compacting trash and unwanted solids from the waste stream. The cleaner, more compact discharge keeps odors to a minimum and lowers disposal costs by minimizing the amount of retained moisture and fecal material sent to the landfill. With the Auger Monster, wastewater screening couldn’t get any easier—it’s the only solution that’s all-in-one!

First, a powerful Muffin Monster® or Channel Monster® grinder pre-conditions the wastewater solids by shredding them into a manageable size that increases surface area, thus preparing the solids for cleaning and removal. The solids are then captured by a perforated screening trough and removed by a rotating auger. As solids are removed, dual spray bars clean off fecal material, returning it to the waste stream. Lastly, the auger then conveys the cleaned solids to the discharge point where the integrated compactor section (optional) squeezes out additional water before discharging the cleaned and dried material into a dumpster.


Q: Does the auger “need” to have a grinder in front?

A: Although the Auger Monster can be configured without the grinder, the grinder’s ability to pre-condition the solids greatly improves overall performance by protecting the auger from damage caused by large solids and increasing the surface area of the solids. The increased surface area allows the spray wash to more effectively remove the soft organics (fecal) and return them to the waste stream for downstream processing. The overall result is cleaner, drier, and more compact solids in the dumpster.

Q: What size solids can go through the auger without damaging it?

A: In general, if a solid is small enough to fit between adjacent spiral flights, it will transport up. However, with a grinder installed, larger solids can be processed without worry of damaging the auger or being able to be transported up.

Q: How often do I have to replace the brush?

A: Many factors affect the lifespan of the auger brush, such as grit, wastewater type, as well as the presence or absence of a grinder. However, 18 – 24 months is a typical lifespan that can be expected.

Q: What should I set my auger run cycle at?

A: In general, a forward bias consisting of short forward-cycle durations with even shorter to no-reverse cycle durations works best by allowing for increased spray wash contact time as well as minimizing brush wear. Twenty seconds is a typical forward-cycle duration and a good start. The cycle duration is programmable and can easily be adjusted to best suit the conditions of the site.

Q: What options are there for catching the discharged screenings?

A: JWC provides site-specific solutions for screenings discharge. There are many different configurations available and are typically decided during initial design. Most popular options include a bagging system or a discharge chute to an easily accessible dumpster. Retrofit kits are available to add a bagging system as well.

Q: How long does the auger spiral last?

A: There are many variables that impact service life (materials of construction, run times, preventative maintenance, etc.). On average, an Auger Monster rotor can last ten or more years with proper care and maintenance.

Q: Does JWC offer any type of preventative maintenance agreement?

A: Yes, JWC offers an annual maintenance agreement for all types of its Engineered Systems. Key components are inspected, rotating equipment is lubricated, grinders are inspected, brushes are inspected and controls are optimized for current site conditions. An agreement can be customized to meet your site’s requirements. Reach out and learn more about your specific model and get a specific plan put together for your needs! CLICK HERE.

Headworks for Smaller Plants – Beyond the Manual Bar Screen

Wastewater bar screen or manual bar screen replaced with Auger Monster at Headworks

Wastewater Bar Screen – Not the Only Option

Water treatment facilities in smaller towns and villages, as well as treatment works supporting institutions, prisons, resorts or remote facilities, have difficult choices to make when selecting a headworks system. All require a solids control strategy, but lower flows and smaller budgets limit the available equipment options.  The historical choice in this situation has been a wastewater bar screen or a raked manual bar screen – but there are better options.  The days of sending an operator with a rake and bucket to the headworks for the daily cleaning duties should be a thing of the past.

A number of different types of equipment can be used to meet these objectives, yet public works engineers should not make that choice lightly. There is not a one-size-fits-all solution that can be applied to every headworks situation. Matching the needs of the facility to the appropriate screen or debris reduction method is paramount for both protecting downstream equipment and ensuring screened out solids are handled efficiently and effectively. The wrong choice can result in headworks systems that do not meet the required level of protection of downstream treatment processes, or a system that is too costly for the plant’s requirements.

This article explores the options for wastewater engineers and plant operators trying to strike the right balance between technology and the available funds while optimizing the plant’s efficiency.  If provides guidance on alternatives to the traditional manual bar screen while not overdesigning a system.

New Vertical Auger Monster Screen Fits Inside Pump Stations

Vertical Auger Monster

The new Vertical Auger Monster captures flushable wipes & protects pumps.

Wastewater pump stations are facing an influx of sewer clogging rags and debris, so JWC Environmental engineers developed a breakthrough Vertical Auger Monster® screening system to fit inside cramped pump stations and provide complete pump protection.

Once installed, Auger Monster model AGV safely and easily screens, cleans and conveys rags and debris straight up and out of the sewer system. This gives collection system managers an affordable new way to remove rags before they can clog sewage pumps and eliminate the wasted time and expense of de-ragging a pump.

The vertical Auger Monster is attached to the wall of the pump station next to the influent pipeline and captures rags, wipes, plastics and trash before they get inside the wet well. The screen is custom built to fit each site and can screen up to 1 million gallons per day (158 m3/h). It can also be installed as a headworks screen for a small treatment plant or lagoon system.

“The 90° Auger Monster opens up a whole new series of applications,” said Rob Sabol, Director of R&D for JWCE. “It fits into a tight footprint to provide complete pump protection by capturing, cleaning and removing rags and trash.”

Even small trash such as cigarette butts can’t escape the Auger Monster. A high-capture rate screening basket with ¼” (6mm) circular openings stops the debris and the rotating auger lifts it to ground level. The patented compaction zone compresses and dewaters material before dropping it into a plastic bag or bin ready for landfill disposal.

Auger Monster model AGV offers these unique features: a Muffin Monster® grinder to shred material so it is easier to wash, convey and compact; a spray wash system removes soft organics and puts it back in the wastewater flow where it belongs, and the compaction zone reduces the volume of material so fewer trips to the landfill are needed.

“The terrible problem with ‘flushable’ wipes in the sewer system requires creative and affordable solutions,” said Scott Kelly, Vice President of Sales and Marketing. “The new vertical Auger Monster screen is the solution collection systems managers will like –it’s affordable, operates automatically and makes pump stations reliable once again.”

Our new vertical screen joins a complete family of Auger Monster screening systems. While AGV screens at 90°, models ACE, AGE and ALE are installed at 35° or 45° for high flow screening. The Auger Monster is popular in the wastewater industry because it incorporates an entire headworks system into a single package – a rugged Muffin Monster® or Macho Monster grinder, screen, washer, conveyor and compactor. It’s an affordable screening solution for small and medium-sized treatment plants with flow rates up to 10 million gallons per day (1,600 m3/h).
