Water & Wastewater Treatment Equipment Serving Memphis, TN
Precision lime slaking, biosolids stabilization, drying, storage, and truck loading systems engineered by RDP Technologies for Memphis and Mid-South municipal facilities.
Trusted Process Equipment for Memphis 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. Memphis-area utilities count on RDP for clean, accurate, reliable systems that are simple and easy to maintain.
Biosolids Storage & Precision Truck Loading Systems
The City of Memphis Wastewater Treatment Division operates the T.E. Maxson Wastewater Treatment Plant on the south side and the M.C. Stiles Wastewater Treatment Plant on the north side of the city, two major Mississippi River-adjacent facilities serving Memphis and parts of Shelby County. Daily biosolids volumes from these plants move to land application and beneficial reuse outlets across the agricultural heartland of West Tennessee, North Mississippi, and Eastern Arkansas. Reliable storage and loadout equipment is essential to keeping that program running consistently through brutally humid Mid-South summers and unpredictable severe weather. 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 Memphis’s intense summer heat and humidity, 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, Memphis-area plant staff can redirect labor toward higher-value work elsewhere in the facility. For utilities managing heavy hauler rotations to Delta region farmland and surrounding agricultural sites, that automation directly improves daily throughput and reduces overtime costs.
Biosolids Lime Stabilization & Pasteurization Solutions in Memphis, TN
Tennessee Department of Environment and Conservation (TDEC) administers biosolids oversight under federal EPA 503 standards, with West Tennessee’s substantial agricultural land base supporting active land application programs across the Mississippi Delta region. The Memphis metro’s location at the convergence of three states adds complexity to biosolids logistics and tri-state regulatory coordination. 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 the Mid-South.
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 relying 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 Memphis-area facilities planning capital upgrades against TDEC requirements or evaluating Class A expansion for broader market flexibility, these are regulator-recognized options with strong long-term track records.
Lime Slaking & Feed Systems for Memphis Water Treatment Facilities
Memphis Light, Gas and Water (MLGW) operates one of the most unusual large municipal water systems in the country, drawing essentially all of its drinking water from the Memphis Sand Aquifer through a network of deep wells across Shelby County. This naturally pristine groundwater source has shaped the city’s identity for generations, but treatment still requires careful pH adjustment, corrosion control, and management of iron and manganese to maintain distribution stability. RDP Technologies designs lime slaking and feed systems engineered for the precision and reliability that high-volume Mid-South 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 the Mid-South. 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 Memphis’s intense summer demand peaks.
Custom Engineering & Process Equipment Support Serving Memphis
Water and wastewater infrastructure across the Memphis metro region carries deep operational history, with facilities serving the area for more than a century and now operating in a tri-state metro region that includes parts of Mississippi and Arkansas alongside West Tennessee. Plants here must handle Mississippi River flood events, severe weather, and the operational realities of serving a major logistics and industrial economy that drives substantial wastewater loadings. RDP Technologies brings over 45 years of custom process equipment engineering experience to capital projects across Shelby, Fayette, Tipton, and the surrounding Mid-South 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 Tennessee Department of Environment and Conservation, Mississippi DEQ and Arkansas DEQ for tri-state partners, and EPA Region 4 oversight.
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. Memphis-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 Memphis Wastewater Plants
With Memphis biosolids volumes moving across a tri-state hauling network and Delta region land application markets continually adjusting, biosolids drying systems offer a strategic capital investment for cutting hauling tonnage and unlocking higher-value end products. 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 Tennessee, Mississippi, Arkansas, and the broader Mid-South region. Pairing the dryer with upstream RDP lime feed or storage equipment gives Memphis 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.
