For over 45 years, RDP Technologies has built process equipment that performs dependably in the field, grounded in a practical engineering approach proven across hundreds of municipal installations. Utilities across Southeast Tennessee and the Tennessee River Valley rely on RDP for accurate, durable systems that stay easy to operate and simple to maintain over a long service life.
Biosolids Storage & Precision Truck Loading Systems
The City of Chattanooga operates the Moccasin Bend Wastewater Treatment Plant, a large regional facility on a bend of the Tennessee River that treats flow from Chattanooga and numerous surrounding jurisdictions across Hamilton County and into North Georgia. Years of investment at Moccasin Bend, much of it tied to a federal consent decree targeting sewer overflows, have modernized the campus and its solids handling. Treatment at that scale produces substantial daily biosolids, and dependable storage and loadout equipment keeps trucks moving to regional reuse and land application outlets on schedule. RDP Technologies engineers biosolids storage systems and precision truck loading systems that automate the full run, from the dewatering line to the fully loaded truck pulling out.
Moving floor technology inside live bottom bin storage keeps heavy sludge cake advancing steadily, heading off the bridging and rat-holing that stall conventional steep-walled hoppers. Loadout runs automatically through the precision truck loading system, closing most loads within minutes and holding within a couple hundred pounds of the operator's target weight.
Three decades and roughly three hundred biosolids conveying installations have refined a bay layout that keeps trucks clean, departures on schedule, and operator attention at the bay minimal. With loading running on its own, Chattanooga-area staff can redirect their hours to higher-value work across the plant. For a program serving a large regional service area across the Tennessee Valley, that automation lifts throughput and holds overtime down.

Biosolids Drying Systems for Chattanooga Wastewater Plants
For a regional plant the size of Moccasin Bend, the weight of biosolids leaving the site is a meaningful and controllable cost, and reducing it becomes especially valuable as reuse and disposal expectations evolve across Tennessee. Drying offers Chattanooga-area facilities a direct path to lower tonnage and higher-value end products. The RDP-Fenton sludge dryer runs on a repeating batch cycle, letting drying time follow the natural variation in cake dryness coming off dewatering rather than a fixed rate.
Batch sludge drying equipment absorbs those upstream shifts cleanly, where continuous-flow dryers often struggle when feed quality changes without warning. Operators in the field regularly note how little daily attention the system needs once a stable recipe is dialed in.
The dried product emerges markedly reduced in volume and weight, cutting trucking costs and opening pathways into fertilizer, soil amendment, and energy recovery markets across Tennessee and the surrounding region. Paired with upstream RDP lime feed or storage equipment, a Chattanooga plant gains a fully integrated biosolids line backed by one manufacturer with consistent controls and ongoing support. Long service life and simple operation guided the design from the start, and installed sites bear that out in real performance data.

Lime Slaking & Feed Systems for Chattanooga Water Treatment Facilities
Tennessee American Water supplies Chattanooga's drinking water, drawing from the Tennessee River and treating it at the Citico Water Treatment Plant, with the river through the city impounded by the TVA-operated Chickamauga Dam upstream. That surface water calls for careful pH adjustment, alkalinity management, and corrosion control across an established distribution network, including the demands of the Lead and Copper Rule. Dependable lime feed sits at the center of that treatment chemistry. RDP designs lime slaking and feed systems engineered to deliver the precision and reliability high-volume Tennessee River operations require.
Tekkem slakers rely on 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 window. That weight-based control enables precision dosing with slurry concentration adjustable from one percent up to thirty percent based on plant requirements.
The same Tekkem platform converts to a hydrated lime feed system without any physical modifications, providing flexibility as lime market conditions shift across Tennessee and the surrounding region. A continuous slurry 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.

Custom Engineering & Process Equipment Support Serving Chattanooga
Chattanooga sits where the Tennessee River carves through the Cumberland Plateau past Lookout, Signal, and Raccoon Mountains, a scenic but constrained setting where the river is held between the TVA-operated Chickamauga and Nickajack dams and the metro reaches across the state line into North Georgia. That geography, along with humid summers, flooding potential, and the demands of a multi-jurisdiction service area, shapes how treatment facilities are designed and run. RDP Technologies brings over 45 years of custom process equipment engineering to capital projects across Hamilton, Bradley, Marion, and neighboring Southeast Tennessee and North Georgia counties.
Because design, fabrication, and controls programming stay under one roof, we tailor equipment to existing tankage, site constraints, and the workflows operators already rely on, rather than forcing a stock package into a poor fit. Our control platforms integrate cleanly with SCADA and meet the detailed reporting the Tennessee Department of Environment and Conservation and EPA Region 4 require.
We work directly with municipal engineers, consulting firms, and plant operations staff from the earliest scoping through commissioning and long-term technical support. Durable equipment, dependable process performance, and practical technology that keeps performing are the principles behind every project we deliver. Chattanooga-area facilities gain a single accountable manufacturer that designs, builds, and stands behind its equipment for the long haul.

Biosolids Lime Stabilization & Pasteurization Solutions in Chattanooga, TN
Tennessee manages biosolids under TDEC oversight, and as PFAS and emerging contaminant concerns reshape reuse expectations across the Southeast, Class A treatment pathways are drawing growing interest for the market flexibility they provide alongside traditional Class B land application. RDP Technologies has delivered EPA 503 compliant lime-based solutions since those federal rules were first established, supporting both Class A biosolids treatment and Class B biosolids stabilization at facilities across Tennessee and the Southeast.
EnVessel Pasteurization is one of the most widely deployed Class A processes in the country, with more than 70 installations in operation. It pairs lime addition with controlled supplemental heat rather than relying on heavy lime overdosing, keeping chemical demand reasonable while reliably meeting 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 pathogen reduction equipment, supported by published case studies and decades of municipal operating data. For Chattanooga-area facilities planning capital upgrades against TDEC requirements and evolving reuse expectations, these are regulator-recognized options with strong long-term track records.
