Our TA effort may include assistance in the following areas:

  • Developing comprehensive process control programs for WWTP's including ENR facilities.
  • Troubleshooting O&M (operation & maintenance) problems affecting plant performance.
  • Providing O&M input relating to plans for upgrading the WWTP.
  • Reviewing NPDES permit requirements and assisting with permit renewals.
  • Assistance developing a PM (preventive maintenance) program for the WWTP and collection system.
  • Assistance developing critical SOP's.
  • Evaluating chemical feed systems for cost effectiveness and efficiency.
  • Assistance evaluating adequate staffing to match the requirements of the facility.
  • Assistance with laboratory procedures.
  • Working with utility staff and management to develop a shared understanding of the responsibilities of all parties to insure consistent compliance with regulatory requirements.

TOWN OF PERRYVILLE
TECHNICAL ASSISTANCE

Town of Perryville

In September of 2015,  a Technical Assistance request was submitted to MCET from the recently hired Superintendent of water and wastewater for the Town of Perryville.

The Town's SBR plant was designed for 1.65 MGD and had been experiencing difficulty in complying with the ENR limits over the past few years. The Town's Superintendent requested assistance from MCET with optimizing the performance of the ENR WWTP in order to consistently comply with the NPDES permit. 

There has been significant progress made in improving the plant performance since the new Superintendent took over the O&M of this facility. Therefore, the TA effort provided by MCET focused on supporting the ongoing activities of the Superintendent with respect to implementing new process control strategies based on MCET’s technical assistance provider's experience with similar facilities in the TA program.

As a result of the actions taken by the Superintendent over the past 2 years, with 'as needed' support from the MCET TA program, the WWTP has consistently been in compliance with the ENR permit limits. In addition, the plant performance has met the Maryland Department of the Environment's requirements to achieve O&M grant funding in 2016 and most probably in 2017 as well.

MCET was also able to assist the Town in pursuing additional ENR grant funds, which will enable the town to add denite filters to the facility. This addition will be an important tool in maintaining consistent compliance with the ENR limits well into the future.

NORTH EAST RIVER ADVANCED
WASTEWATER TREATMENT FACILITY (NERAWWTF)

TECHNICAL ASSISTANCE

NERAWWTP

A Technical Assistance (TA) request was submitted to MCET by the plant manager in September, 2017 to provide assistance with optimizing the chemical feed program in order to insure consistent compliance with the ENR limit for TP.

This 4-stage Bardenpho facility is designed for 2.0 MGD and had a major upgrade completed in mid 2016 to comply with the ENR permit limits established by MDE. The upgrade included modifications to the Oxidation Ditches as well as replacing the clarifiers and filters with new membrane technology. The new ENR permit went into effect in January, 2017.

Since the facility was not in full operation through the summer of 2016, the first experience with warm weather operation occurred in 2017. Although the TP results were meeting ENR limits during the first part of the year, the facility started to see an increase in effluent TP levels as the temperature increased in the biological process. Based on the experience of the MCET provider, with a number of other ENR facilities that have been part of the TA program, an increase in TP levels during warm weather conditions was a common occurrence.

Considering that the NERAWWTF depended on chemical addition of Polyaluminum Chloride, the focus of the TA program involved working with plant staff to increase the chemical dose to levels that would maintain consistently low levels of TP as the ML temperature exceeded 20 degrees C. Ultimately this effort will enable staff to be more prepared for next summer based on this years experience.
