Description

The BIOROCK Monoblock-2 is a below-ground non-electric sewage treatment plant. Being powerless, this makes it ideal for off-grid applications in remote locations such as Camping, Glamping and Shepherds' Huts. Being non-electric also helps with those Green Credentials as well as reducing the risk of noise pollution from traditional electric air blowers. The Monoblock 2 is suitable for up to 6 persons (6PE) in a full-time situation or up to 4 bed house.

If a higher outlet is required, there is an option to specify a pump station. However, this will require an electricity supply. Despite using electricity, this plant would still be cheaper to run, as it doesn't have an air compressor running constantly or intermittently.

 

Benefits of the BIOROCK Monoblock:

  • No electricity required
  • No moving parts or air compressors
  • Low running costs
  • Minimal maintenance
  • Silent operation
  • Capable of coping with low flows and periods of absence
  • 25-year warranty on the tank and 5 years on the media
  • Eco-friendly technology
  • CE Marked
  • Tested to EN 12566-3 and SR 66

 

How it works in three easy steps:

  1. The Primary Tank - Clarifies the raw sewage, removing fats, grease, and oils. The sewage water then passes through the effluent filter and discharges into the BIOROCK Reactor.
  2. Bioreactor Process - The Bioreactor further purifies the pretreated wastewater through a biological process, naturally treating the wastewater. The BIOROCK media is a very efficient carrier material for bacteria.
  3. Discharge - Depending upon the ground type, effluent will be discharged by gravity or by a pump (pumps require an electricity supply)
