Easy, Non-intrusive Installation

Designed to be Installed in One Day

The LandSaver® MBR is designed for installation ease and flexibility. It is a three-chamber system that can be installed in either lightweight plastic or more traditional concrete tanks. It includes an integrated UV unit that eliminates installation of an additional chamber to add disinfection. Controls are pre-wired for UV and spray system hook-up and include self-monitoring and self-cleaning features.


  • Capacity: 600 gallons per day (depending on State Specific Approval)
  • Power: 230 VAC single phase
  • Electrical: 4-wire, double pull breaker

Simple, Plastic Tank Configuration

In a plastic tank configuration, the Primary Tank and Equalization Tank are set together and fed by gravity with wastewater from the building. The Aeration/Ultrafiltration Tank, which contains the Ultrafiltration Unit, is fed with pumped effluent from the Equalization Tank and has a pumped return to the Primary Tank. If necessary, this tank can be separated from the others and does not require leveling. Tanks are delivered to site fully assembled, and only require simple interconnections, installation of the riser and lid, positioning of the blower housing, and connection of the prewiring to the control panel. Infiltrator brand tanks are pictured. 

Lightweight plastic tanks allow for fast installation with no heavy lifting equipment.

Traditional Concrete Tank

Tangent Company provides concrete tank dimensions for pre-casting by distributors/assemblers. Three separated chambers allow for primary collection, equalization and aeration/filtration. The LandSaver® MBR Ultrafiltration Unit is housed in the third chamber. A single tank or multiple tanks can be used.  Tanks must meet applicable state requirements.
