- Blackwater Recycling Systems



Blackwater is any wastewater that is contaminated with water discharged from a toilet. Compared to greywater recycling, it is often more practical to recycle blackwater as most plumbing systems don’t separate greywater streams e.g. showers, basins. Aquacell S systems can often be retro-fitted to existing buildings or be installed in new developments without dealing with dual plumbing complexities.

Despite many commercial facilities and multi-dwelling apartments having the option to discharge wastewater directly into a local municipal sewer network, onsite blackwater recycling is attractive to many sites for a number of reasons including:

  • Reducing onsite water use by up to 90 per cent
  • Contributing points to a LEED development or pro-actively demonstrating good environmental management
  • Providing an additional source of water to keep gardens and sports fields green; many parts of the U.S. have limited water resources available for aesthetic uses
  • Reducing the hydraulic impact of a development on a local municipal sewer. This overcomes development restrictions caused when the existing sewer is at its hydraulic capacity.

The Aquacell S Series gives commercial developers modular solutions to onsite blackwater recycling. The system features a controlled, robust and comprehensive treatment process that combines physical, microbiological and oxidative treatments into the one package:

  • Collection point – Water flows from the property to a collection point, whereby it is pumped into the Aquacell to begin the treatment process.
  • Screening – The first step efficiently reduces insoluble material to a negligible residue. This residue is either discharged to sewer or it is de-watered and compacted for disposal as solid waste.
  • Biological Treatment – Air is diffused into the water to create optimum conditions for bacteria to consume impurities. A sustainable biomass concentration is maintained, which metabolizes all incoming waste – resulting in negligible sludge.
  • Ultrafiltration– Ultrafiltration occurs through a special membrane of microscopic pores that prevents particles, bacteria and viruses from passing through. The membranes are cleaned by air scouring, ensuring no waste water is produced.
  • Ultraviolet disinfection– As a precaution, Ultraviolet lamps are provided. These act as a further barrier, providing additional protection against pathogens.
  • TDS and nutrient removal– Proprietary technologies are employed for applications such as cooling tower reuse and discharge to sensitive environments.
  • Chlorination– Finally, a chlorine residual is added to protect the water while in storage and the reticulation system – the only time any chemicals are used throughout the treatment process.
  • Treated water storage– The result is safe water, kept in storage for immediate use in a variety of non-potable applications, including surface irrigation, toilet flushing and cooling towers.

The Aquacell S Series offers high recovery rates without backwashing, negligible residue and low energy usage. These features provide maximum credits for LEED projects. Aquacell is the ideal option for green builders.

Our systems include a built-in control instrumentation which continuously reacts to the ever-changing quality of effluent without an onsite operator. Our expertly trained Aquacell engineers remotely monitor all systems via the internet, twenty-four hours a day, seven days a week.

Aquacell has delivered numerous localized blackwater treatment/recycling solutions. We have the experience and knowledge to navigate complex regulatory frameworks and ensure positive blackwater recycling outcomes are achieved. Data acquisition and compliance reporting is built into the Aquacell system from the ground up. All our systems are backed by expert knowledge, service and maintenance support. This is our ongoing guarantee to ensure your peace of mind.
