Many owners and operators of traditional decentralized municipal wastewater treatment plants, also referred to as on-site or off-grid treatment, are acutely aware their systems are at risk of becoming obsolete. These systems include:
- septic fields
- oxidation ditches and ponds
- rotating biological contactor (RBC) mechanisms, and
- sequencing batch reactor (SBR) processes.
Why the concerns?
Recreational vehicle and mobile home parks, residential and commercial developments, campgrounds, and private utilities are increasingly challenged to treat wastewater cost-effectively when facing:
- the probability of more stringent discharge quality requirements in the years ahead
- the capital costs to upgrade or replace existing facilities
- water scarcity issues and the demand to beneficially reuse treated wastewater
- the pressure to keep the plant easy to operate and maintain
- the need to scale operations as treatment demands grow
- limited space to build and upsize
- unpleasant odors arising from collection and treatment activities
- a social imperative to offer a sustainable process to minimize the environmental impact.
However, an advanced wastewater treatment technology known as the Membrane Aerated Biological Reactor, or MABR, is particularly well-suited to overcome each one of these challenges.
