Waterbrane™ – A new generation of filtration treatment

Waterbrane™ – for industrial water

Aquarden’s WaterbraneTM is a filter unit that can be used for many types of filtration applications. It is ideal for treatment of oily wastewater or separation of sludge in wastewater from the metal finishing and surface treatment industry.

The Waterbrane filter unit is made of a silicon carbide (SiC) filter module and replaces a traditional settling tank and a sand filter, which are applied in most treatment plants for industrial wastewater.

Waterbrane can therefore be used for most of the se­pa­ration tasks where settling tanks and sand filt­ers are used today.

The compact design of Waterbrane makes it an obvious choice where space is a constraint as it takes up only 10-20 % of the space of a traditional setup.

How it works

Aquarden’s Waterbrane consists of a small tank with a built-in filter module made of silicon carbide membranes. Wastewater with particle pollutants is fed continuously to the tank. Clean water is sucked out through the filter, while the sludge particles are collected and concentrated in the conical bottom as a thin sludge. The pore size of the SiC membranes is 0.1 µm which mean that particles larger than 0.1 µm are concentrate in the sludge.

The Waterbrane unit is typically supplied with a flow from 1 to 100 m3/h. In principle there are no limits to the plant capacity as the units are modular.

Flexible setup

The SCWO systems are installed onsite at our clients’ premises right at the source of pollution, or at local cleaning stations.

We charge a competitive fee per treated cubic meter of wastewater. In this way companies can focus on their core businesses instead of having to worry about – or invest in – wastewater treatment systems. And we can focus on our core competence: helping our customers in optimizing their wastewater treatment.

Main benefits
  • High performance: Removes particles larger than 0.1μm. Higher flux than most standard micro filtration systems. Automated back-flush maintains a constant high flow.
  • A two-in-one solution: The Waterbrane unit replaces a traditional settling tank and a sand filter.
  • Easy maintenance: Slower fouling compared to traditional polymer membranes due to a special filter design.
  • Small footprint: Takes up only 10-20 % of the space of a traditional solution with settling tank and sand filter.
  • Robust design: Long lifetime of the SiC filter module.
  • Low water consumption: A fraction of the filtrated water is used for back-flushing which means no extra water is added.
  • Water reuse: Filtrated water may be reused in the production instead of being discharged to the sewer. 

Main usages
The Waterbrane™ can be used for most of the se­pa­ration tasks where settling tanks and sand filt­ers are used today. Some possibilities include:
  • Safe Intake water for fish farming plants.
  • Separation of heavy metal sludge particles from industrial wastewater and acid mine drainage (AMD).
  • Treatment of scrubber water from power plants and ships.
  • Filtration of surface water to produce drinking water.
  • Filtering of process baths containing particles of metal hydroxides, metal sulfides and metal phosphates.
  • Cleaning of contaminated surface water and leachate.
