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.

Protecty Ejector pump sewage systems with grinders for waste water pump clogs

Ultimate Ejector Pump Protection! Facility Waste Water Pump Clogs & Pipe Back-ups Can Be Stopped!

Managing facilities can present daily challenges. The last thing a facility manager wants to deal with is a problem with the on-site sewage systems. Protect your facility from toilet backups, expensive ejector pump repairs and even worse raw sewage spills by installing a JWC sewage grinder. The JWC dual shafted low speed high torque Monster grinder can shred adult diapers, rags, wipes and anything else into small particles ensuring they flow harmlessly through pumps!  Stop repairing your waste water pump and install a permanent solution to your problems – a JWC sewage grinder – the ultimate in waste water pump protection!

Is Facility Under Siege for one of these issues?

  • Emergency Plumbing Repairs – usually nights and weekends?
  • Costly clean-ups of spills due to ejector pump failures?
  • Notices of Violation (NOV) from municipal water authority for clogging their down stream pumps?  (You don’t want this letter)
  • Foul Sewage Odors drawing complaints from guest and residents?

industrial sewage grinders, inline and open channel, waste water pump protectionDepending on what is being flushed down the toilet, most pumps will tend to clog!  The JWC sewage grinder protects downstream pumps continuously, so no matter what is flushed, you don’t have to worry.  Your JWC Monster grinder will easily chew it up into small pieces so the opportunity for your ejector pump or waste water pump to clog is eliminated.

The problems do not stop at the facility’s on-site pump station and sewage systems.  Often locations that are known for discharging sewage with heavy solids, like hospitals, nursing homes and jails will cause clogs in the municipal sewage systems.  The municipal waste treatment authority will often demand the facility take some action to resolve the problem and even issue a Notice of Violation.

Green Muffin Monsters Devour Airport Blue Water!

Green Muffin Monsters Devour Airport Blue Water!

Installation of the Aircraft Waste Disposal Facility Was Stage 2 of the Sydney Airport Water Recycling Project

As part of Sydney International Airport’s Redevelopment, JWCE distributor Xylem Water Solutions Australia was contracted by the airport to install a clean, efficient way to dispose of  ‘blue water’  – wastewater pumped from airplane lavatories. Airplane lavatories are constantly subjected to a broad variety of non-disposable items that ultimately clog downstream sewer lines, pumps and processes.

The new Aircraft Waste Disposal Facility, houses two Muffin Monster channel grinders in a below-ground well, allowing lavatory carts to drive up and unload the blue water and the vacuum toilet waste from the airplane. Wet and dry solids flow via an inlet pipe into the station’s dual-shafted grinders, which use two shafts of sharp steel rotating cutters to chop up solids like plastic, textiles, foreign object debris (FOD) and paper. Ground-up material is then flushed into the local sewer system and the tiny pieces pose no threat to downstream pumps.

With over 33 million passengers using Sydney Airport in 2008, much of the waste being disposed of is pumped directly from the airplane lavatories. The installation of the Muffin Monster Model 30005s in 2008 was an important step in their waste management strategy.  Equipped with immersible motors, these Monsters are protected from stormwater run-off and increased flow rates during heavier traffic seasons.

The rugged design of the grinders has eliminated most of the clogging downstream, saving maintenance costs and time. By minimizing waste solids, Sydney Airport has been successful in reducing its overall costs and impact on the environment.

JWC also offers another solution for airport waste management with the Monster Airport Receiving Station – a self-contained, below grade and automated station that allows for simple, odor-free, clean and efficient wastewater disposal.
