Material Matters conducted a Biosolids Processing Master Study for Nazareth Borough Municipal Authority (NBMA) to assist in making future program decisions. As part of the continuation of the 2006 Biosolids Master Study, Material Matters assisted Nazareth Borough with a dewatering pilot study using Eimco Electrodewatering equipment. Samples were collected over a three-day pilot to analyze the energy efficiency, dewatering capabilities, recycle flow impacts, odor potential, and class A EQ cake potential of the equipment. A final report was written and presented to the Authority in addition to holding an open house for municipal and regulatory facilities to see the pilot unit operate and present findings of the study.
In 2010, an environmental firm proposed to install a dryer unit at the New Oxford Municipal Authority wastewater plant to process biosolids. The New Oxford Municipal Authority employed Material Matters to complete a pilot with the dryer unit, and to evaluate the capacity of the wastewater treatment plant to handle three scenarios of imported materials - septage, treated sludge, and dewatered biosolids cake to support the installation and operation of a regional biosolids dryer. The evaluation included an examination of the capacity of each unit in the treatment process and the effects of recycle flows on the plant, as well as the volume of solids generated per day of operation.
Material Matters was enlisted in the spring of 2013 by the Wyoming Valley Sanitary Authority (WVSA) to assist with developing a beneficial use program that would replace its existing biosolids disposal via on-site incineration with disposal of the ash in a local landfill. Material Matters conducted a lime addition study at the WVSA wastewater treatment plant to determine how much lime addition is required to: meet pathogen reduction (PR) standards and vector attraction reduction (VAR) standards; manage nuisance odors generated by undigested biosolids cake; and determine if a lime-stabilized biosolids beneficial use program is a cost-effective option compared with incineration. The evaluation included a bench-scale lime addition/mixing study determine the optimal lime addition rate for PR/VAR and odor control, and was followed by with a full-scale pilot at the WWTP. Material Matters also identified potential beneficial users for the Authority, and completed a cost analysis to confirm that lime addition / beneficial use is a cost-effective option for the Authority.
