Water & Wastewater Treatment Equipment Serving Baltimore, MD

Precision lime slaking, biosolids stabilization, drying, storage, and truck loading systems engineered by RDP Technologies for Baltimore and Chesapeake Bay region municipal facilities.

Trusted Process Equipment for Baltimore Water & Wastewater Plants

For over 45 years, RDP Technologies has been building robust equipment, backed by dependable process performance, based upon a foundation of practical technologies that simply perform. Baltimore-area utilities count on RDP for clean, accurate, reliable systems that are simple and easy to maintain.

Biosolids Storage & Precision Truck Loading Systems

Baltimore’s Back River Wastewater Treatment Plant and Patapsco Wastewater Treatment Plant are two of the largest in the Mid-Atlantic, serving Baltimore City and surrounding Baltimore County with substantial daily biosolids volumes that must be moved consistently to land application and beneficial reuse sites across the region. The Chesapeake Bay TMDL has placed additional operational scrutiny on these facilities, making dependable storage and loadout equipment essential to maintaining steady program performance. RDP Technologies engineers biosolids storage systems and precision truck loading systems that automate the full flow from dewatering through to the departing truck.

Moving floor technology built into live bottom bin storage keeps sticky sludge cake flowing reliably through Mid-Atlantic seasonal swings, eliminating the bridging and rat-holing common to conventional steep-walled hoppers. Sludge cake truck loading runs automatically through the precision truck loading system, with most loads completed within minutes and held to within a couple hundred pounds of the operator’s target weight.

Three decades and approximately three hundred biosolids conveying equipment installations have refined a layout that keeps trucks clean, departure times predictable, and operator involvement minimal at the bay. Because the cycle runs without continuous attendance, Baltimore-area plant staff can redirect labor toward higher-value work elsewhere in the facility. For utilities managing heavy weekday hauler rotations to Eastern Shore and Mid-Atlantic agricultural land application sites, that automation directly improves daily throughput and reduces overtime costs.

Biosolids Lime Stabilization & Pasteurization Solutions in Baltimore, MD

The Chesapeake Bay TMDL has driven sustained pressure on Maryland wastewater utilities to reduce nutrient loads and modernize biosolids handling, with the state’s nutrient management framework adding additional planning complexity to capital projects across the region. RDP Technologies has been delivering EPA 503 compliant lime-based solutions since the federal rules were first established, supporting both Class A biosolids treatment and Class B biosolids stabilization at facilities across Maryland and the broader Chesapeake watershed.

The EnVessel Pasteurization biosolids pasteurization system is one of the most widely deployed Class A processes nationally, with more than 70 installations operating across the United States. EnVessel pairs lime addition with controlled supplemental heat instead of leaning on heavy lime overdosing, keeping chemical demand reasonable while reliably hitting the time, temperature, and pH thresholds required for full pathogen kill.

Enhanced Pasteurization moves the cycle into a sealed sequencing batch reactor where lime drives pH above 12 and controlled heating completes disinfection. Both pathways serve as proven wastewater pathogen reduction equipment, supported by published case studies and decades of operational data from municipalities nationwide. For Baltimore-area facilities planning capital upgrades against Maryland Department of the Environment requirements and Chesapeake Bay restoration targets, these are regulator-recognized options with strong long-term track records.

Lime Slaking & Feed Systems for Baltimore Water Treatment Facilities

Baltimore City Department of Public Works operates the Montebello and Ashburton filtration plants, supplying drinking water to Baltimore City and parts of Baltimore, Howard, Anne Arundel, and Harford counties from the Loch Raven, Liberty, and Prettyboy reservoirs. Lime feed plays a central role in pH adjustment, corrosion control, and Lead and Copper Rule compliance across one of the oldest and most extensive municipal water systems in the country. RDP Technologies designs lime slaking and feed systems engineered for the precision and reliability that high-volume Mid-Atlantic municipal operations require year-round.

The Tekkem family of lime slakers for water treatment applies load cell technology to combine a measured weight of quicklime with a measured weight of water, holding the slaking reaction within the proven 180°F to 190°F temperature window. This weight-based control approach enables precision lime dosing systems with slurry concentration adjustable from one percent up to thirty percent based on plant requirements.

The same Tekkem platform converts to operate as a hydrated lime feed system without any physical modifications, providing flexibility as lime market conditions shift across Maryland and the broader Mid-Atlantic. A continuous slurry delivery loop combined with pinch valve and flow meter dosing supports accurate feed at multiple application points within a facility. With only one moving part inside the reaction tank, maintenance demands stay infrequent and predictable for plants running around the clock through Baltimore’s variable seasonal demand cycle.

Custom Engineering & Process Equipment Support Serving Baltimore

Water and wastewater infrastructure across the Baltimore metro region carries deep operational history, with many treatment facilities serving the area for more than a century in various forms and continually modernized to meet evolving regulatory demands. Plants here must handle Chesapeake Bay nutrient compliance, coastal storm events, and the operational complexities of serving a dense urban core surrounded by rapidly developing suburban counties. RDP Technologies brings over 45 years of custom process equipment engineering experience to capital projects across Baltimore City, Baltimore County, and the surrounding Maryland metro region.

As a wastewater treatment equipment manufacturer that handles design, fabrication, and controls programming under one roof, we adapt to existing tankage, constrained urban site footprints, and operator workflows rather than forcing a generic package into a difficult location. Our intelligent control platforms integrate cleanly with SCADA systems and meet the detailed reporting expectations of Maryland Department of the Environment, Chesapeake Bay Program oversight, and EPA Region 3.

We engage directly with municipal engineers, consulting firms, and plant operations staff from early scoping through commissioning and long-term technical support. Robust equipment, dependable process performance, and practical technologies that simply perform are the principles that have guided every project we deliver. Baltimore-area facilities benefit from working with a single accountable manufacturer that designs, builds, and stands behind the equipment for the long haul.

Biosolids Drying Systems for Baltimore Wastewater Plants

Reducing hauling tonnage and lowering nutrient loads on Chesapeake Bay watershed lands make biosolids drying systems an attractive long-term capital investment for Baltimore-area wastewater plants. The RDP-Fenton wastewater sludge dryer operates on a repeating batch cycle that allows drying time to be adjusted to match the natural variation in sludge cake solids concentration coming off the dewatering line.

Batch sludge drying equipment handles those upstream variations cleanly, whereas continuous-flow dryers often struggle when feed quality shifts unexpectedly. Operators in the field have repeatedly noted how little daily attention the system requires once a stable recipe is dialed in.

The dried product comes out significantly reduced in volume and weight, lowering trucking costs and opening pathways into fertilizer, soil amendment, and energy recovery markets across Maryland, Virginia, Pennsylvania, and the broader Mid-Atlantic region. Pairing the dryer with upstream RDP lime feed or storage equipment gives Baltimore wastewater plants a fully integrated biosolids handling line backed by a single manufacturer with consistent controls and ongoing support. Long service life and ease of operation were the design priorities from the start, and that focus shows up clearly in real-world performance data from installed sites across the country.
