BIODISK Corporation

- Portable Wastewater Treatment Plants


To facilitate the application of our proven BIODISK wastewater treatment technology in remote applications, we have developed two unique new packages, which we call Big John and Little John. These two applications are used for the treatment of sanitary wastes from up to 333 and 166 persons respectively at construction sites and permanent installations….usually at remote locations.

The Big John and Little John packages combine two proven technologies….the BIODISK and the ISshipping container. The package makes use of our Rotating Biological Contactor (RBC) process and houses it in 40 and 20 foot long shipping containers. On site, the shipping containers become an integral part of the sanitary wastewater treatment facilities.

Combining our BIODISK RBC wastewater treatment process with ISshipping containers, has proven thave many advantages and benefits over conventional approaches to wastewater treatment:

  • Ease of shipping and greater accessibility to remote locations
  • Easy, quick set-up requires very little assembly and takes advantage of unskilled or low skilled labour….can be ready for operation in as little as a day after delivery
  • Shipping and set-up costs are considerably less than for conventional wastewater treatment facilities
  • Operating costs are considerably lower than for other treatment systems
  • Power consumption is low
  • Low operator skill requirements - operator involvement is limited to preventative maintenance and periodic biosolids withdrawal
  • Long term sludge storage
  • Totally enclosed systems
  • Low odour
  • Low noise
  • Built-in multi-stage process takes advantage of naturally occurring microbes
  • Safe….nopen ponds or exposed tanks
  • A unique and self regulating process

Big John and Little John provide the “full package” including secondary treatment and effluent disinfection. They alsinclude all controls and necessary housing.…truly a “Turn Key” design for a sewage treatment facility in a box.

  • We will be there tsupport you with our after care service which includes:
    • System Start-up
    • Process Evaluation
    • Spare Parts
    • Trouble Shooting if Required


Our systems use a natural process for the treatment of wastewater utilizing RBCs. The process meets or exceeds effluent requirements as specified by regulatory agencies. The process has many inherent operational characteristics that make it ideally suited for the treatment of domestic wastewater.

Our systems discharge to:

  • Sub-surface and surface absorption components
  • Surface waters
  • Intermittent streams
  • Storm water management facilities

Self Regulating

The treatment process easily accommodates flows ranging from 0 t100 percent of design. The biomass on the RBC media is directly proportional tthe organic material received. The process is self-regulating without supervision.
