Howard County, Maryland Sets The Pace In Restoring Chesapeake Bay Ecosystem
Howard County, Maryland, Bureau of Utilities recently completed the $92-million Addition No. 7 project at the Little Patuxent Water Reclamation Plant (LPWRP) to improve the quality of the plant’s effluent discharge and to reduce harmful nutrients reaching Chesapeake Bay. The project’s various increments took over five years to complete and incorporated innovative design solutions and state-of-the-art technologies for denitrification, aeration and disinfection. The project presents a model for Maryland’s 66 largest wastewater treatment plants and possibly procurement of municipal facilities elsewhere facing increasingly stringent regulatory changes.

Paper Facility Increases Efficiency With Filter Rehabilitation
NewPage operates eight paper mills in the United States. The Biron mill located in Wisconsin Rapids, Wisconsin produces approximately 370,000 tons of paper each year.
Clarification System Boosts Capacity, Reduces Maintenance
Spikes in peak demand at the 3.0 MGD Freedom District Water Treatment Plant in Carroll County, MD, exceeded 70 percent of the plant’s capacity, and the existing clarifier made for a lengthy sludge-removal process. After staff installed a dissolved air flotation (DAF) pretreatment system to improve the efficiency of the membrane filters, the now 4.0 MGD facility has reduced maintenance for operators. The system also safeguards against pathogens that can pass through traditional sand/diatomaceous (S/D) filters.
How A Wisconsin Paper Mill Increased Capacity And Improved Water Quality
In late 2012, production capacity issues arose with several of the clay tile filters at the NewPage Biron paper mill in Wisconsin. Process engineers decided to retrofit two of their four existing dual cell filters with an underdrain system and media retainer. This case study details the system and explains how it doubled capacity for the two filters and improved effluent water quality, leading to fewer plant shutdowns due to seal failures within the mill.
