Custom Engineering & Process Equipment Support Serving Nashville

Nashville's water and wastewater system has been under steady modernization, much of it driven by the Clean Water Nashville Overflow Abatement Program, the federal consent decree behind a long, costly campaign to cut sewer overflows across Davidson County. RDP Technologies fits that kind of work well, applying a custom process equipment engineering practice that reaches back more than forty-five years to facilities run by Metro Water Services.

RDP handles engineering, fabrication, and controls programming itself rather than subcontracting it out, which lets equipment be shaped to a plant's existing tankage, limited footprint, and the way its operators already work. Controls integrate with SCADA and generate the reporting detail that TDEC and EPA Region 4 expect from permitted facilities in Tennessee.

Through scoping, fabrication, startup, and the long service life that follows, RDP works directly with Metro engineers, consulting firms, and plant staff. The company's guiding ideas have not changed: robust equipment, dependable performance, and technology practical enough to simply work. Whether a project is a single lime feed retrofit or an entire biosolids treatment line, Nashville clients work with one manufacturer accountable for the equipment over the long haul.

Biosolids Drying Systems for Nashville Wastewater Plants

For plants serving a metro growing as fast as Nashville, the cost of hauling and disposing of biosolids climbs right alongside the population, which makes biosolids drying systems worth a hard look. The RDP-Fenton wastewater sludge dryer runs a repeating batch cycle, which lets operators match drying time to the shifting cake solids coming off a dewatering line rather than fixed to a single setting.

Batch sludge drying equipment rides out that variation comfortably, where continuous dryers can falter when the upstream feed jumps unexpectedly. Operators tend to remark on how seldom the unit needs attention once a workable recipe is locked in, which frees staff for other duties.

The dried output leaves the system much lighter and reduced in volume, cutting haul weight while opening reuse channels across energy-recovery, soil-amendment, and fertilizer markets in Tennessee and the wider Southeast. With RDP lime feed or storage equipment set ahead of it, that integrated chain shares one control scheme and one accountable manufacturer for the long run. Long service life and straightforward operation drove the original design, a point borne out by performance figures from installed sites.

Biosolids Storage & Precision Truck Loading Systems

Metro Water Services keeps biosolids moving from its Central, Dry Creek, and Whites Creek plants on a continuous basis, and the equipment at the loadout has to hold that flow steady through Middle Tennessee's wet springs and humid summers. RDP pairs biosolids storage systems with precision truck loading systems so material travels from dewatering to the waiting truck without crews handling it by hand.

A moving floor inside live bottom bin storage keeps thick, tacky cake on the move where ordinary steep-sided hoppers tend to bridge and rat-hole. Sludge cake truck loading then proceeds automatically under the precision truck loading system, finishing a load in minutes and staying within a few hundred pounds of the operator's chosen weight.

Hundreds of biosolids conveying equipment projects on, RDP has settled into a loadout setup that keeps trucks clean and moving with almost no one stationed at the bay. Because the system loads on its own, Nashville plant staff can spend their time on tasks that genuinely need them. For utilities juggling busy hauler rotations, that reliability turns into fewer bottlenecks and lower overtime.

Lime Slaking & Feed Systems for Nashville Water Treatment Facilities

Nashville draws its drinking water from the Cumberland River, treating it at the Omohundro and K.R. Harrington plants before it heads out across Davidson County. Here lime works less as a heavy softening agent and more as a tool for pH adjustment, alkalinity control, and corrosion protection in the distribution network, and RDP engineers lime slaking systems and lime feed systems precise enough for that finer kind of dosing.

RDP's Tekkem lime slakers for water treatment meter quicklime and water by weight using load cells, holding the slaking reaction in the range where the chemistry stays clean and efficient. That weight-based method is what underpins precision lime dosing systems, and it lets operators trim slurry strength to exactly what corrosion-control targets call for instead of overshooting. Steady dosing through the Cumberland's seasonal turbidity swings keeps treated water within spec.

The same Tekkem equipment converts to a hydrated lime feed system with no mechanical changes, giving Nashville flexibility as lime markets move. Feed stays accurate at several points across a plant by way of a recirculating slurry loop and metered valves. With a lone moving part in the reaction tank, upkeep is minimal and predictable for plants operating without pause.

Biosolids Lime Stabilization & Pasteurization Solutions in Nashville, TN

Biosolids handling around Nashville operates under layers of TDEC and federal oversight, and RDP Technologies has furnished lime-based treatment for this work since the EPA 503 rule first set the terms. The RDP biosolids lime stabilization line reaches from Class B biosolids stabilization for routine land application up to full Class A biosolids treatment when a cleaner, more marketable product is the aim.

EnVessel Pasteurization, RDP's biosolids pasteurization system, ranks among the most widely fielded Class A processes in the country, with better than 70 units in service. Rather than dumping in excess lime, EnVessel combines a measured dose of lime with added heat to reach the time, temperature, and pH marks that full pathogen kill requires, holding chemical costs in line.

When an enclosed process is preferred, Enhanced Pasteurization carries the sequence into a sealed batch reactor where lime lifts pH past 12 and controlled heat closes out disinfection. Both qualify as documented wastewater pathogen reduction equipment, supported by documented case studies and a deep well of municipal operating history. For Nashville facilities planning capital improvements, each is a route TDEC and EPA already accept.
