Pilot Test ASO® MBBR

Aerobic Bio System

US Patent #D827765

PEWE Pilot Test System

PEWE offers complete pilot testing of water and wastewater streams for the purpose of proofing its treatability. The pilot test MBBR system is skid mounted for easy transportation, comes with an experienced operator for set-up, trialing and the return shipment. The MBBR pilot is a fully scaled version of its larger “brothers”, is constructed in stainless steel and PVC wetted parts for corrosion resistance, utilizes twin VFD driven regenerative turbine blower technology and is operated with the PEWE Command Control® system.

The unique technology built into the MBBR pilot system maximizes COD and BOD reduction while eliminating the need for RAS, lowers chemistry usage and sludge production. Pilot testing provides management with the valuable data needed for making key design and return on investment decisions.

The standard rental is for twelve weeks. Additional testing may be arranged as necessary. To schedule a pilot MBBR test trial, simply complete the rental agreement, select a test period and forward the advance payment.

PEWE also offers the PEWE Nx2JEM® DAF Pilot system when water characteristics such as TSS and FOG require pretreatment.

Lab Testing

PEWE recommends before and after lab tests be conducted on representative water samples. This testing should reflect the facilities typical daily wastewater discharges. Lab tests generally include TSS, TDS, TBOD, COD, BOD, FOG, TKN, TP and pH. Lab test costs are not included in the pilot rental.

Pilot Utilities

The electrical control panel is designed for 480v 3 phase 60Hz power and has a 30 amp maximum current draw. Installed power is 1.0 Hp with capability of additional field devices. Additionally, the on-board DO meter and running light require 110v power from a separate source. There are also 2 power outlets for an optional de-foam system, field test accessories or lap-top. Fresh water is necessary for dilution of chemicals and final cleaning of the equipment.


PEWE will arrange with your choice of chemical vendor to supply the appropriate type and quantities of required chemicals. Testing is suggested prior to selecting any chemical program. The cost and delivery of these chemicals are not included with the pilot rental.

Bio Solids

The biological solids are removed by a simple mechanical filter. The permeate may then be tested for the desired characteristics as required by the test protocol.
