Water & Wastewater Treatment Equipment Serving Pittsburgh, PA
Precision lime feed, biosolids stabilization, drying, storage, and truck loading systems engineered by RDP Technologies for Pittsburgh-area municipal facilities.
Trusted Process Equipment for Pittsburgh 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. Pittsburgh-area utilities count on RDP for clean, accurate, reliable systems that are simple and easy to maintain.
Biosolids Drying Systems for Pittsburgh Wastewater Plants
Disposal logistics across western Pennsylvania put real pressure on wastewater plants to drive down hauling weight, which is where biosolids drying systems deliver some of the clearest operating savings available. The RDP-Fenton wastewater sludge dryer runs on a repeating batch cycle that lets drying time be adjusted to match the natural variation in sludge cake solids concentration coming off the dewatering line.
Batch sludge drying equipment handles those swings without trouble, whereas continuous-flow dryers often struggle when upstream output shifts unexpectedly. Field operators have repeatedly pointed out how little daily attention the system needs 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 western Pennsylvania and the broader Ohio Valley. Pairing the dryer with upstream RDP lime feed or storage equipment gives Pittsburgh wastewater plants a fully integrated biosolids handling line backed by a single manufacturer with consistent controls and long-term support. Long service life and ease of operation guided the original design, and that focus shows clearly in real-world performance data from installed sites nationwide.
Custom Engineering & Process Equipment Support Serving Pittsburgh
Water and wastewater infrastructure throughout the Pittsburgh region has been built and rebuilt across many decades, with treatment facilities often shaped by river geography, hilly terrain, and a long industrial legacy. RDP Technologies brings over 45 years of custom process equipment engineering experience to projects across Allegheny County and the surrounding southwestern Pennsylvania region.
As a wastewater treatment equipment manufacturer that handles design, fabrication, and controls programming under one roof, we adapt to existing tankage, demanding site footprints, and established operator workflows rather than forcing a generic package into a difficult location. Our intelligent control platforms integrate with SCADA systems and meet the detailed reporting expectations of Pennsylvania DEP and EPA Region 3 oversight.
We work directly with municipal engineers, consulting firms, and plant operations staff from early concept through commissioning and ongoing technical support. Robust equipment, dependable process performance, and practical technologies that simply perform are the principles that have guided every project we deliver. Pittsburgh-area facilities benefit from working with a single accountable manufacturer that designs, builds, and stands behind the equipment for decades.
Lime Slaking & Feed Systems for Pittsburgh Water Treatment Facilities
Pittsburgh’s drinking water systems draw from the Allegheny and Monongahela rivers, supplying treated water to communities throughout the city and the broader metro region. RDP Technologies designs lime slaking systems and lime feed systems engineered around the precision and uptime that high-volume municipal river-source operations require.
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 180°F to 190°F window where the chemistry performs at its best. That weight-based control foundation is what enables precision lime dosing systems with slurry concentration adjustable from one percent up to thirty percent depending on plant requirements.
The same Tekkem platform can run as a hydrated lime feed system without any physical changes, providing flexibility as lime market conditions shift across the western Pennsylvania and Ohio Valley region. A continuous slurry delivery loop combined with pinch valve and flow meter dosing delivers accurate feed at multiple application points within a facility. With only one moving part inside the reaction tank, maintenance demands stay low and predictable for plants running around the clock.
Biosolids Storage & Precision Truck Loading Systems
Treatment plants serving the Pittsburgh region work with hilly sites and constrained urban footprints, which puts a real premium on biosolids handling equipment that is compact, reliable, and easy to maintain. RDP Technologies engineers biosolids storage systems and precision truck loading systems that automate the full path from dewatering equipment to the departing truck.
Moving floor technology built into live bottom bin storage keeps sticky sludge cake moving consistently even through cold western Pennsylvania winters, sidestepping the bridging and rat-holing common to conventional steep-walled hoppers. Sludge cake truck loading runs automatically through the precision truck loading system, with loads typically completed within minutes and accuracy held to within a couple hundred pounds of the operator’s target weight.
Three decades and roughly 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 constant attention, Pittsburgh plant staff are freed up for higher-value work elsewhere in the facility. For utilities managing demanding weekday hauler rotations, that automation translates directly into reduced overtime and smoother daily logistics.
Biosolids Lime Stabilization & Pasteurization Solutions in Pittsburgh, PA
Biosolids handling for utilities in and around Pittsburgh, PA carries decades of regulatory history, and RDP Technologies has been delivering compliant lime-based solutions in this space since the EPA 503 rules were first established. Our biosolids lime stabilization product line supports both Class A biosolids treatment and Class B biosolids stabilization, giving southwestern Pennsylvania utilities flexibility based on disposal strategies and beneficial reuse goals.
The EnVessel Pasteurization biosolids pasteurization system stands as one of the most widely deployed Class A processes in the country, with more than 70 installations operating across the United States. EnVessel pairs lime with supplemental heat instead of leaning on heavy lime overdosing, keeping chemical demand reasonable while reliably hitting the time, temperature, and pH targets needed for full pathogen kill.
Enhanced Pasteurization moves the work into a sealed sequencing batch reactor, where lime drives pH above 12 and controlled heating finishes the disinfection cycle. Both options qualify as proven wastewater pathogen reduction equipment, backed by published case studies and decades of operational data from municipalities nationwide. For Pittsburgh-area facilities planning capital upgrades or evaluating new approaches, these are regulator-recognized pathways with strong long-term track records.
