The FAST System, which can also be housed in a container. Bolt-on additions can cope with hundreds of extra workers or visitors

By CST Wastewater Solutions

The latest Smith and Loveless FAST water quality and recycling solution is being introduced to Australia by CST Wastewater Solutions to manage groundwater impacts and comply with increasingly stringent sustainability requirements for developments in remote areas.

The easily installed FAST (Fixed Activated Sludge Treatment) system produces an Australian effluent water quality from Class C to Class A, which means the water produced by large remote mining, oil & gas, tourism, education, commercial and industrial communities, for example, can be recycled for processes around the site.

The latest FAST systems available in flow capacities of 24-4000 cubic meters a day are the most recent developments of technology proven throughout Australia in major mining operations, smaller municipal councils, schools, tourist facilities, commercial developers, and private industry.

CST Wastewater Solutions Managing Director Michael Bambridge says that the systems are ideal for public and private organizations seeking to optimize their achievement of high water quality standards within a high-efficiency, low-maintenance system that accommodates shock loads, variable flows and seasonal operations.

FAST achieves outstanding Biological Nutrient Removal (BNR) for applications containing high levels of nitrogen, the water pollutant that has increased significantly in Australian industrial, commercial and municipal applications and which is an environmental concern, particularly to resources, engineering, construction, hospitality, marine, agribusiness and public facility and water and wastewater infrastructure organizations.

Complete, Easily Operated System
The plant arrives on-site essentially as a plug and play system requiring only a concrete pad and some relatively minor mechanical and electrical works. Class A effluent is achieved by the addition of a filter and UV sterilization after the FAST system, says Mr. Bambridge. The latest versions of the fixed biofilm process, with enhanced nutrient removal, achieves Biological Nutrient Removal (BOD and TSS) down to 10mgl; total nitrogen (TN) removal to 8mg and ammonia (NH3) and total phosphorous (TP) removal down to 1mg/l.

Proven in thousands of installations worldwide, FAST consists of tankage packed with completely submerged media. The FAST media creates a high surface area-to-volume ratio, which, combined with internal settling zones, maintains constant bacterial growth during low-flow and peak usage periods typical of many remote installations. This results in stable operation on a daily basis.

“Simple operation and maintenance mean no daily operator requirements and very little annual plant maintenance,” says Mr. Bambridge, whose company’s installations of the FAST system have been proven in Australian applications including Alcoa, BHP-Billiton, South 32, Tahmoor Colliery, Cadia Gold, Anglo American and many more in the mining industry. Further installations have been completed for the Central Coast Grammar School, CSIRO, Hunter District Water Kiama Municipal Council, Lakeside Leisure Park and Berowra Waters Marina.

The QUCKSMART™ PLC touchscreen controls available on the latest FAST systems provide outstanding ability to monitor and adjust treatment system functions with a highly intuitive, easy-to-navigate touchscreen PLC interface. Cloud-based RemoteView motorizing services are available.

FAST system features and benefits include:

  • Modular design and construction
  • Low sludge production
  • No moving parts, except for an air blower that provides oxygen while circulating the liquid.
  • Requires little maintenance, with no daily operator requirements and very little annual plant maintenance.
  • The latest QUCKSMART™ TLC touchscreen controls make automation and data monitoring even easier.
  • Robust and reliable performance, in terms of the process. The fixed media through which the wastewater circulates provides a high surface area-to-volume ratio, protecting against hydraulic shock loads.
  • Longer sludge age than typical biological systems, increasing water quality efficiency
  • Higher loading rates, giving a smaller plant footprint
  • Lower solids to clarifier, to improve settling
  • No bacterial washouts
  • No biocarrier cog replacements or related clogging

“The FAST system is the perfect solution for remote projects because it can be built into standard shipping containers,” said Mr. Bambridge. “The modular format of the FAST System also allows an easy bolt-on for any expansion in workforce.

Key: 1: Flexible Process Zones, Configured, 2: Efficient & Robust Aeration/ Circulation, 3: Media Air Scouring [Automatic], 4: Smart Wire Management System, 5: Clarifier Selection, 6: Safe & Easy O&M Access [Factory-Supplied] Clarifier Selection, 7: No Plant Reseeding, 8: Influent Transfer Eliminates Pump O&M, 9: QUICKSMART™ PLC Touchscreen Ease, 10: RemoteView™ Cloud Remote Monitoring also available.

For any future proposed increase of workers, it is a simple matter of adding another FAST 20-foot Module. This could be incorporated in the design, he said.

Not only does the system achieve higher loading rates within a smaller footprint, but effluent produced can be recycled into suitable industrial, public facility, and commercial re-use processes.

A FAST installation in Australasia. Systems in this format can be readily expanded to cope with hundreds more workers on sensitive sites.

“The FAST system in mining projects allows the ecologically responsible operator to reuse the effluent water for dust suppression and lubrication water, for example, which helps with their environmental footprint,” says Mr. Bambridge.


“The FAST System has been proven in Australasia and globally as being a very robust and simple system to operate. It is very reliable because its stable process withstands hydraulic shocks and the bacteria involved are not washed out. It is simple to operate and requires no daily operator maintenance, which results in low annual maintenance costs. Low maintenance is a great advantage in that the need for costly and often distant engineering support is radically curtailed.”
