The ABSORBS™ system is an advanced secondary performing natural treatment and dispersal system designed specifically to deliver low-cost, reliable treatment performance.  The ABSORBS™ technology is suitable for use in on-site domestic (up to 1,200 L/d) and decentralised commercial (>5,000 L/d) wastewater applications throughout Australia and is suitable for any soil type in line with site-specific engineering and design requirements.

The ABSORBS™ has the smallest dispersal footprint of any advanced secondary system in Australia. This is because it can achieve higher treatment quality than many treatment systems (such as Aerated Wastewater Treatment System: AWTS) and takes advantage of the benefits of sub-surface dispersal methods.  The ABSORBS™ system is certified to comply with Australian Standard AS 1546.3:2017 at advanced secondary effluent quality (≤10/10/10 BOD5/TSS/turbidity) and achieves partial nutrient reduction performance (21% total nitrogen and 30% total phosphorus).

The system uses passive nature-based wastewater treatment to deliver the highest possible performance on the smallest footprint achievable, and with the lowest ongoing operating costs to the home owner of any advanced secondary certified system in the Australian market.  The ABSORBS™ operates on a natural aeration dynamic from mass exchange of atmospheric oxygen into the soil/filter.  The entire system is effectively passive once discharged through the pump. If there is no water produced the system remains in stand-by and is ready for service at any time without adverse performance impacts.

This makes the ABSORBS™ an excellent choice for sites with variable flows such as holiday homes or Cellar Doors.  No chemicals are used in the system as both the secondary treatment and dispersal train are completely sub-surface.  Being fully underground, the ABSORBS™ can be planted over with turf, helping the system blend seamlessly into the landscape giving improved site amenity performance compared to AWTS systems with surface irrigation.  The ABSORBS™ system is designed to be installed either in fully lined or unlined (bottomless) configurations in compliance with local regulatory requirements and site engineering requirements.  The small footprint in combination with the highest treatment performance, lowest operating cost and capacity to handle variable flows and difficult soil conditions makes ABSORBS™ the first choice treatment and dispersal option.
