WATER SOLUTIONS

EARTH SUSTAINING SCIENCES CENTRE THEIR WATER SOLUTIONS ON THE SABR PROCESS

THE SYMBIOTIC AQUATIC BIOREACTOR  (SABR)

Wayne Sampey,  developed, implemented and proved the SABR system has the ability to treat all levels of acid mine drainage (AMD), extreme alkaline process drainage, other metals and organic reagents, and salinity contaminated waters and soils.

SABR allows reduction of unwanted, sub-compliant water volumes utilising tailored bioreactors to correct pH issues at all levels (0-14 pH) and remove contaminants; decreasing contamination of water, soil and the environment, thus reducing risk. SABR is scalable to any required size and throughput using open systems. In situations where space is at a premium or contaminants may be especially hazardous, the systems can be implemented in closed systems.

Complex chemistries often result in a system where conditions appropriate to strip one class of contaminants are conducive to stabilisation of others in solution. SABR allows serial reactor implementation using different sets of biocells, such that consecutive manifolds can control all contaminants. SABR can rapidly, naturally and cost effectively treat AMD/ARD and process waters to a standard that allows their safe use or disposal on site, or discharge off site with negligible risk and within compliance requirements. SABR is quick to implement and quick to bring online. Initial tailoring of the approach is through lab based wet chemistry, followed by small scale cost effective on site pilot reactors to determine a site specific bio-tuning and demonstrate that the full scale system will deliver appropriate results.

The SABRBODS process is a unique combination of naturally occurring, localised, cooperative bioorganisms formed into manifolds or SABR Symbiotic Colonies (SABR-SC). Thus far, 360 different SABR-SC’s have been developed and proven in a wide range of conditions. It delivers commercially viable management solutions and is a societally sustainable management solution to challenging effluent and contamination, especially in agriculture.  The SABRBODS process, passive, local taxon structured water and soil treatment systems have thus-far successfully remediated all globally presented soil and water challenges with the demonstrated ability to raise the pH to 8.7pH (up to 9pH) or reduce it from 14 pH to 6.1pH balancing the realised effluent to neutral, stripping up to 99% of bioavailable metals and metalloid contaminants and significantly reducing salinity (now up to more than 95%).


 Engineered examples of scalable open SABR systems


SABR Systems are scalable to any required size and throughput using open systems. In situations where space is at a premium or contaminants may be especially hazardous, SABR can be implemented in closed systems. Complex chemistries often result in a system where conditions appropriate to strip one class of contaminants is conducive to stabilisation of others in solution. SABR allows serial reactor implementation using different sets of biocells, such that consecutive manifolds can control all contaminants. SABR can rapidly, naturally and cost effectively treat acidic and alkaline process affected soil and water, (0-14 pH) reducing metals, metalloid and other contaminants to a standard that allows their safe use, disposal on site, or discharge off site with negligible risk and within compliance requirements.

SABR is simply and quickly implemented. Initial tailoring of the approach is through wet chemistry, and small scale on-site pilot reactors to determine site specific biotuning and demonstrate the ability of a full-scale system. The biotuning process allows optimisation of the SABR system to site specific donor geology, commodity beneficiation processes, water chemistry and climate.

Following more than twenty years of development and field proving, SABR has demonstrated effectiveness in waters associated with coal mines, gold mines, platinum mines, iron mines, phosphate refinery effluents, phosphogypsum effluents, acid refinery effluents, polymineral, rare earth element and radiogenic element bearing effluents, power station effluents, fly ash effluents, agriculture, and coal, gold, copper, zinc, lead, phosphate, poly metals, bauxite/alumina and iron ore tailings facilities. In all cases SABR delivered the solution.

In all cases SABR enabled remediation of the disturbed ecology and rapid reinvigoration of riverine, riparian, lacustrine, wetland, littoral and soil systems.

The SABR water solutions application assessments are conducted over 14-days, incorporating:

  •       Site and regional and potentials investigation,
  •       Design of substrates and minimal risk microbiological manifolds, and development of plans,
  •       Design of tailored SABR bioreactor application pilot and system.
