Grease Trap-Trade Waste Arrestor

Trade Waste Arrestor Applications

All ATQ Arrestor systems are designed and fabricated to local and state regulation specifications, and are coated with Megapoxy MC, a heavy duty protective coating for use on concrete when used for storage for chemicals, foodstuffs, fuel etc and is resistant to abrasion, impact and a wide range of chemicals.

Our Grease Traps are installed in commercial service and manufacturing environments such as the automotive industry, food manufacturing facilities, kitchens, restaurants and retail food service to trap grease, oil and contaminants before they enter waste and water pipelines to prevent build-up and damage to the waste lines, water treatment facilities, and the environment.

The Silt Arrestor acts as a filter system with an internal (removable) strainer. With a steel grate and frame cover located into ground level of wash down bays, Silt Arrestors are used in kitchens, food preparation areas, commercial and bin wash bays, auto and mechanic repair workshops, and car/truck wash bays.

Our Cooling (straining) Arrestor is suitable for when warm/hot waste water needs to be retained until it has cooled to a legally acceptable temperature prior to be discharged into the water or sewer systems. With two chambers, the first is a straining chamber to trap lint and foreign objects before the waste water enters the second chamber, being the cooling chamber.

Main uses for a Cooling Arrestor is in combination with Lint Arrestors used in laundries, hospitals, hotels, nursing homes and commercial venues.

Lint Arrestors with removable straining baskets are installed wherever lint and other foreign objects require removal from wastewater, such as hospitals, aged care, nursing homes, hospices, and hotels, motels, commercial laundries and laundromats.

The Australian Tanks Lint Arrestors are also designed to cool the flow of water to lower the temperature of the waste to meet legal requirements.

The ATQ Acid Neutralising Arrestor is our holding tank used to normalise the pH level of waste water that contains high levels of acid before being discharged into waste water and sewer pipelines. Fabricated with three internal baffles, filled with acid neutralising marble chips (sold separately), the three baffles propel the liquid and acidic waste through the tank and filters past the marble chips. This method neutralises the acid and allows pH balanced water to safely discharge.

Multiple and varied applications for the Acid Neutralising Arrestor include any industry generating acidic waste water such as laboratories, battery storage, art/craft workshops, metal industry workshops, and agricultural industries such as diaries.

Why choose Australian Tanks?

Our solutions are designed for small, medium, or large capacities and compete extremely favourably with alternative precast or built-on-site systems. Additionally, the lifecycle costs measure extremely well against alternatives as they are very easy to access, clean and maintain.

Every Australian Tanks system is delivered with weir walls, filtration, penetrations, trash screens, ladders, risers, manholes, drainage holes and orifice plates in place, ready for immediate install in the prepared site excavation. Importantly, all systems are pre-cured with no further waterproofing required. Installation takes place in hours, not weeks, to be connected and backfilled within the same day.

We provide tanks that are made to Australian Standards to allow for restricted heavy vehicle access based:

  • Heavy duty construction rated for where the heaviest vehicle traffic will be a 4 axle twin steer truck eg. garbage truck.
  • Un-restricted traffic loading in accordance with AS5100 can be provided with further engineering for your needs.

Our range of tanks are easily interconnected in multiples to create any volume quickly and cost effectively. Every system is certifiable, with increasing numbers of engineers incorporating our systems into their designs due to the structural integrity and multiple efficiencies of our service.

Our products are easily modified to fit the volume required on your project. Along with other on-site parameters we can create the ideal custom solution for you and your team.

Trade waste arrestor Design and Ratings

The full range of Australian Tanks Trade Waste Arrestors, Tanks, Ring Pits and Pump Stations are a ‘single pour’ precast concrete tank, constructed with a built-in anti-floatation base where no additional ballast is required for installation in high water table areas.

The unique anti-floatation design provides on-site efficiencies and financial savings from potentially not having to manage water trucks on-site to add ballast in the tanks (May still be required prior to backfilling depending on the water height), and not requiring project management of concrete trucks to pour and tie in a ballast footing.

All Australian Tanks Arrestor systems are precast concrete and coated with Megapoxy MC, a heavy duty protective coating for use on concrete when used for storage for chemicals, foodstuffs, fuel etc and is resistant to abrasion, impact and a wide range of chemicals.

Designed and fabricated to local and state regulation specifications and approved for use by multiple Councils.

Australian Tanks are regularly requested to replace tanks that have
been driven over and damaged.

Many times these tanks have been installed in non-trafficable areas,
such as parks and school ovals, but have been inadvertently driven over, only to find the tank has been unable to bear weight with the resulting damage requiring new tank installation.

To avoid these damaging risks Australian Tanks provide tanks that are manufactured to Australian Standards (AS5100.2) and are rated up to ‘unrestricted heavy vehicle access’ based on the SM1600 traffic
design loads;

  • Heavy Duty Tank: Rated for where the heaviest vehicle traffic will
    be a 4 axle twin steer truck (Max GVM 27.5t). Example: Garbage

  • Extra Heavy Duty Tank: Rated up to unrestricted heavy vehicle
    access based on the SM1600 traffic design loads in accordance
    with AS5100.2 Bridge Design Code. Example: Fire Engine

The professional manner in which Australian Tanks approached this project resulted with the successful installation of several large capacity grease interceptor traps that are fully compliant with the City of Gold Coast Trade Waste Department requirements. Congratulations to Les Green and Team for the professionalism, and a quality product.
Aaron Glowka
Project Manager
The service from the team is outstanding, they’re always available to help. They’ll do whatever they can including come out and work you to get it right. The different volume tanks are brilliant! Standard sizing that you can adjust the volume makes it uniform when working across different jobs. Consistency in area for planning also helps to save time and money in the long run!
