The latest range of MBR wastewater treatment systems available from CST Wastewater Solutions meets the reliability and low maintenance requirements of companies operating in remote or physically challenging environments.
Many of these resources and infrastructure companies will need to focus on environmentally effective wastewater treatment systems as they pause for the traditional Christmas New Year maintenance season to consider their technology needs for the year ahead.
Increasingly stringent regulatory requirements mean that not only do companies need to ensure their discharges are treated to high quality standards, but also that wherever possible water is recycled to make best use of this precious shared community resource.
The latest Smith and Loveless TITAN MBR QUBE and proven FAST wastewater treatment systems installed in Australia by CST Wastewater Solutions build on an outstanding record encompassing diverse infrastructure, construction, oil and gas and mine sites.
One of Australia’s first FAST (Fixed Activated Sludge Treatment) plant was installed more than 30 years ago at Xstrata’s Tahmoor Mine in NSW; the plant still continues to successfully treat effluent to high discharge standards.
According to CST Wastewater Solutions Managing Director Mr Michael Bambridge, there are units in the Bowen Basin of Queensland that have been in service for 20-30 years, while many more similarly compact S and L FAST units are giving excellent service in Australia and globally.
TITAN MBR QUBE system
The latest Smith and Loveless MBR (membrane biological reactor) wastewater treatment system, the TITAN MBR QUBE, provides a simply installed, low maintenance and environmentally effective wastewater treatment system suitable for remote resources, construction and tourism sites.
The TITAN MBR QUBE comes in a standard HC (40-foot High Cube) container, completely factory pre-assembled, packaged and delivered. The plug-and-play unit needs only a flat pad to sit on along with connections to water and electricity.
TITAN MBR QUBE also features submerged flat-plate membrane technology that ensures high permeability and flux rates, providing end-users with high quality treatment performance coupled with minimal operational requirements for applications involving flows in the range of 25-100m³ a day. This robust and efficient low maintenance system is proven in diverse industrial and municipal applications where strong environmental performance is mandatory.
TITAN MBR QUBE’s flat-plate membrane design results in less wear and tear than hollow-fibre types and can easily be cleaned in place. Air scouring prevents fouling and eliminates the need for back-pulsing pumping equipment.
The technology is custom-engineered for situations such as those encountered by mining, oil and gas and remote infrastructure construction sites, which require strong ongoing protection of shared community water resources through a standalone system that doesn’t require complicated ongoing operating skills and knowledge.
TITAN MBR systems come in standard and custom designs, with a smaller footprint than conventional systems. The submerged membrane eliminates the need for clarifiers and sand filters, producing significantly better effluent quality. Integral zones can be added to meet particular effluent goals, including nutrient removal, disinfection, sludge holding and post-aeration.
TITAN MBR QUBE low maintenance technology uses gravity pressure to drive water flow through its membranes. Clean water discharges into a clear well, while blocked solids remain suspended in the aeration zone. Diffusers beneath the module scour the membranes while also providing an air supply to the bacteria.
The highly durable membrane is composed of PVDF and non-woven polyester fabric. Vertical membrane surfaces do not touch each other during operation. The design prevents breakage typically experienced in other designs and produces higher flux rates over time.
TITAN MBR QUBE membranes eliminate clogging problems experienced in hollow-fibre designs, with their smooth, continuous surfaces preventing build-up of solids that result from hollow fibres being bundled by stringy solids such as hair. The flat surfaces also facilitate air scouring in the aeration zone much more effectively than hollow-fibre designs.
The membranes maintain high permeability and flux rates even at peak-day rates. Chemical cleaning occurs efficiently in place semi-annually, with simple chemical injection. TITAN MBR membranes are also designed to use less chemicals and equipment than other designs.
High performance Titan MBR units provide effluent quality of < 3 mg/L BOD and < 1 mg/L TSS while turbidity is < 2 NTU, TKN is < 2 mg/L and NH3 is < 1 mg/L.
FAST process system
Reliable and low maintenance FAST process systems are available in factory-built or field-installed modules, providing high performance treatment in a minimal space.
Designed to handle smaller, variable flows generated from onsite applications, including schools, small developments, commercial and public facilities, and hospitality venues such as hotels, camps, and restaurants, the modular FAST system does not require daily operation, and the installations provide significantly improved performance over traditional leach field and septic tank systems, especially when a nitrification/ denitrification component is specified in permit or effluent requirements.
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; when combined with internal settling zones, it maintains constant bacterial growth during low-flow and peak usage, resulting in stable performance on a daily basis.
