The Challenge

RPM is a plastics recycling plant that processes a variety of resins including HDPE, LDPE, PVC, PP, and PS. RPM utilizes a custom-designed washing system that required a wastewater treatment.

 

The Design

Biowater’s CMFF® Two-stage Moving Bed Bioreactor technology was implemented as a wastewater treatment system. This design was selected for its ability to handle not only high strength wastewater, but also variations in flows and loadings with minimal operator attention.

Parameter    Limit/target Actual
Design Flow 200 m3/day     200 m3/day
BOD5 737 mg/L (147 kg/d) 15 mg/L (3 kg/d)
TSS 166 mg/L (33kg/d) 20 mg/L (4 kg/d)
TKN 86 mg/L (17 kg/d) 3.9 mg/L (0.78 kg/d)
Phosphorus  11 mg/L (2 kg/d) <0.2 mg/L (<0.04 kg/d)
Design WW Temp. 24 - 35˚C  
Site Elevation 751 ft AMSL  

 

Achievements

Biowater’s effluent data are on average 95 percent below the respective limit. The installation successfully meets its performance standards.

The BioWater CMFF® biological process - a concept where moving plastic carriers with fixed biofilm remove organic and inorganic substances in the water.
