Clear Cubed Modular MBR Plant with two containers

Clear3® (clear-cubed) MBR.ST Packaged Membrane Bioreactor Plants for Housing Developments, Mobile Home Communities, RV Parks, Seasonal Facilities + More Flows from 5,000 to 237,700 GPD

Clear3 MBR.ST Packaged Sewage Treatment Plants are specifically designed for smaller flows such as Home Developments, Mobile Home communities, RV parks, campgrounds, seasonal communities and recreational facilities. These often have requirements for strict sewage discharge limits but with lower and variable volume requirements. Often there is compelling reason for water reuse on the site.

Clear3 MBR.ST Packaged Sewage Treatment Plants are custom configured for your site with the Clear3 standard treatment modules and either in-ground or above-ground tankage. Tankage can be fiberglass, steel or concrete.

Clear3 MBR.ST Packaged Sewage Treatment Plants Package Plants are equipped with Suez ZeeWeed® Membranes

Need more flow or a custom system?

In many cases failing or undersized septic systems, sometimes coupled with new more stringent nutrient discharge limits is dictating an upgrade in technology. As well, limited space or the opportunity to use existing space for more units may be an economic driver for elimination of large septic beds.

Technical information

Newterra’s Clear3 MBR technology addresses a wide range of wastewater treatment applications where high quality effluent is required, either to meet regulatory requirements or for reuse.
Clear3 MBR targets Biological Oxygen Demand (BOD), Total Suspended Solids (TSS), Bacteria, Total Coliforms, Ammonia, Nitrogen, and Phosphorus.
Clear3 MBR also eliminates many pharmaceuticals from the waste stream, which is a growing concern for natural habitats and drinking water. With extensive experience with groundwater remediation, Newterra can also bring solutions for emerging contaminant challenges such as PFAS and other compounds that may be present in the system effluent.

Discharge Targets (Typical Base Design)
Biological Oxygen Demand (BOD) <5.0 mg/L
Total Suspended Solids (TSS)         <5.0 mg/L
Ammonia-N                                        <1.0 mg/L
Turbidity                                               <0.5 NTU
Total Phosphorus                               <0.1 mg/L
Total Nitrogen                                     <5.0 mg/L

Enhanced Nutrient Removal Design can achieve lower effluent results:
Total Phosphorus                               <0.05 mg/L
Total Nitrogen                                     <3.0 mg/L
The ultimate process configuration is highly dependent on:
  • influent concentrations
  • variability in feed strength and flow
  • desired effluent criteria depending on the ultimate receiver
  • space available
  • budget available
  • climate considerations
  • shipping constraints
  • power available


  • Housing Developments
  • Mobile Home Communities
  • RV Parks
  • Campgrounds
  • Golf Courses, Recreation Facilities, SPAs
  • Retirement Homes
  • Condos, Marinas, Hotels
  • Cluster Communities
  • Religious Communities
