Thanks for the question.  A Package sewage treatment plant is a completely self contained system for sewage treatment that is ‘plug & play’ and should incorporate the following elements in one outer tank;

  1. Include adequate primary and final settlement/clarification.
  2. Adequate biological treatment.
  3. Sludge Storage, preferably at least 3 months.
  4. Sludge return from final settlement (if required).
  5. Be delivered ‘ready to go’.
  6. Fully road transportable assembled.
  7. Fit inside a standard 40 foot container for transport.

In essence it should be a complete sewage treatment solution that does not require extra tanks to work e.g. extra settlement/sludge storage.

The diagram below shows what a package sewage treatment plant should contain;

Other highly desirable traits;

  1. Fully portable when completely assembled and can be moved if required.
  2. Can be placed above/below/partially below ground without a concrete surround.
  3. Requires minimal maintenance, power and spare parts.

One such system that was designed with the above in mind is the BMS Blivet Package Sewage Treatment Plant, which meets all the above criteria.  For this reason it was the only specified package sewage treatment plant for all US Military camps in Iraq after testing against other systems.

The Blivet has been exported via truck/40 foot container to 40+ countries worldwide over 20+ years.  It is proven in every conceivable environment and climate extreme.
