Treatment System Operation/maintenance Including Design and Consulting

1. Environmental Systems Design Services in Rhode Isalnd

 M&A is providing design, compliance and permitting assistance to a 100,000 square foot jewelry manufacturing facility to employ 400-500 workers, throughout all phases of construction and start-up. Engineering design services include engineering designs for LEV and LEV hoods, APC, electroplating, metal finishing and cleaning processes, wastewater treatment, rinsewater and DI rinsewater and ultrasonic cleaner recycling, pretreatment systems, and related collection and distribution systems. Activities include specification and plan development, bidding, vendor drawing review, O&M manual development, start-up, testing, and training assistance. Related activities include completing applications for air emission permit, industrial wastewater discharge permit, hazardous waste EPA identification number, preparing a hazardous waste contingency plan and Rhode Island recycling plan.

2. Groundwater Treatment System Design, Installation and O&M Services

 M&A undertook this New Bedford, MA site assessment. The feasibility study, testing, construction, startup, troubleshooting, and permitting services resulted in a groundwater pump and treat system consisting of oil/water separation, iron chelating agent feed, iron filter, pumping, flow measurement, bag filter, anthracite clay bed, activated carbon bed, and discharge to surface water. M&A provides periodic Operation and Maintenance Services including periodic site visits, and system monitoring from M&A's office by telemetry.

3. Industrial Wastewater Treatment System Design

 M&A provided comprehensive assistance throughout all phases of the project to develop a new wastewater pretreatment system for a leading producer of silver-plated plastic electrodes in Fitchburg, MA. The project evolved over a period of three years. The new pretreatment system consists of wastewater equalization, ion exchange regeneration, batch cyanide destruction, chromium reduction, chromium precipitation using hydroxide chemistry and silver precipitation using sodium dimethyldithiocarbamate, microfiltration solid/liquid separation, sludge storage, and sludge dewatering.
