Lime Slaking & Feed Systems for Toledo Water Treatment Facilities
Toledo draws its drinking water from the western basin of Lake Erie, treated at the Collins Park Water Treatment Plant, a conventional lime softening facility where lime feed is central to removing hardness and supporting coagulation. That source also made national headlines during the 2014 harmful algal bloom, when microcystin from a western Lake Erie cyanobacteria event triggered a multi-day do-not-drink advisory across the region. Managing hard, nutrient-laden lake water demands tight control over pH, softening, and treatment chemistry day in and day out. RDP designs lime slaking and feed systems engineered to deliver that control reliably at high-volume Great Lakes treatment operations.
Tekkem slakers meter on weight, using load cells to bring a measured mass of quicklime together with a measured mass of water while holding the reaction inside the proven 180°F to 190°F range. Because dosing is governed by weight rather than volume, accuracy stays high and operators can set slurry concentration anywhere from one to thirty percent to suit the plant, a real asset for a lime softening operation.
With no hardware changes, the same Tekkem unit runs as a hydrated lime feed system, giving flexibility as lime supply and pricing shift across the Great Lakes region. A continuous slurry loop with pinch valve and flow meter dosing places accurate feed at every application point a plant requires, and with just one moving part inside the reaction tank, upkeep remains light and predictable under round-the-clock demand.

Custom Engineering & Process Equipment Support Serving Toledo
Water and wastewater infrastructure across the Toledo region works at the intersection of two demanding realities: the western Lake Erie nutrient challenge that drives phosphorus reduction and Ohio's H2Ohio water quality push, and a Great Lakes climate of hard winters, lake-effect snow, ice, and Maumee River flooding. RDP Technologies brings over 45 years of custom process equipment engineering to capital projects across Lucas, Wood, Ottawa, and neighboring Northwest Ohio counties.
Because design, fabrication, and controls programming all stay in-house, we shape each system around the tankage already in place, the limits of the site, and the way crews actually operate, instead of forcing a catalog package into a spot it was never meant for. Our control platforms integrate cleanly with SCADA and meet the detailed reporting the Ohio EPA and EPA Region 5 require.
Our engineers stay close to the municipal engineers, consulting firms, and plant crews on each job, from the opening scope through startup and the years of support that follow. Rugged builds, reliable process outcomes, and no-frills technology that simply keeps running are the values guiding everything we ship. Toledo-area facilities gain a single accountable manufacturer that designs, builds, and stands behind its equipment for the long haul.

Biosolids Storage & Precision Truck Loading Systems
The Toledo Bay View Wastewater Treatment Plant handles the bulk of the metro area's wastewater and discharges to Maumee Bay, which places it squarely in the middle of the western Lake Erie phosphorus and nutrient reduction effort. Treatment at that scale, together with the ongoing combined sewer work under the Toledo Waterways Initiative, produces steady daily biosolids, and Northwest Ohio's surrounding farmland offers ready land application outlets. Dependable storage and loadout equipment keeps the trucks moving to those fields on schedule through the full swing of Great Lakes weather. RDP Technologies engineers biosolids storage systems and precision truck loading systems that automate every step, from the dewatering line to the fully loaded truck pulling away.
Live bottom bin storage uses moving floor technology to keep heavy sludge cake in steady motion, sidestepping the bridging and rat-holing that stall conventional steep-sided hoppers, even through cold Ohio winters. Loadout proceeds automatically through the precision truck loading system, most loads done in a matter of minutes and held within a few hundred pounds of the weight the operator dials in.
Roughly three hundred biosolids conveying installations over three decades have shaped a bay arrangement that keeps trailers clean, holds departures to schedule, and asks little of the operator on hand. With the loadout cycle self-managing, Toledo-area crews are free to spend their time on higher-value tasks elsewhere in the facility. For a program hauling to farmland across the Northwest Ohio countryside through snow and ice season, that automation lifts throughput and holds overtime down.

Biosolids Drying Systems for Toledo Wastewater Plants
With Lake Erie nutrient pressure keeping a spotlight on how the region handles its residuals, and hauling costs always in play, cutting biosolids weight is one of the most effective moves a Toledo-area plant can make. Drying offers a direct path to lower tonnage and higher-value end products. The RDP-Fenton sludge dryer works on a repeating batch cycle, letting drying time follow the natural variation in cake dryness coming off dewatering rather than a fixed rate.
The batch design absorbs inlet swings smoothly, where continuous dryers tend to struggle when cake quality moves without warning. Teams operating the unit routinely point out how little day-to-day attention it needs once a stable recipe is dialed in.
Product leaving the dryer is markedly lighter and reduced in volume, cutting trucking costs and opening access to fertilizer, soil amendment, and energy recovery outlets across Ohio and the Great Lakes region. Set downstream of RDP lime feed or storage equipment, a Toledo plant gains a single-source biosolids line with shared controls and one support relationship. Long service life and simple operation shaped the design from the outset, and installed sites back that up with real performance data.

Biosolids Lime Stabilization & Pasteurization Solutions in Toledo, OH
Ohio's biosolids program runs under Ohio EPA oversight, and while Northwest Ohio farmland has long supported Class B land application, growing attention to nutrients, emerging contaminants, and reuse markets is drawing more utilities toward Class A material and the flexibility it brings. RDP Technologies has built EPA 503 compliant lime-based systems from the moment those federal rules came into force, serving both Class A biosolids treatment and Class B biosolids stabilization at plants throughout Ohio and the Great Lakes states.
EnVessel Pasteurization ranks among the most widely installed Class A processes in the country, with a base of more than 70 systems. It works lime alongside a controlled dose of added heat instead of piling on excess lime, which keeps chemical use down while steadily meeting the time, temperature, and pH marks that a complete pathogen kill demands.
Enhanced Pasteurization carries the process into a sealed sequencing batch reactor, where lime drives pH past 12 and controlled heat completes disinfection. Both routes stand as proven pathogen reduction equipment, documented across published case studies and decades of municipal operating data. For Toledo-area facilities planning capital work against Ohio EPA requirements and Lake Erie nutrient goals, they are regulator-recognized options with strong, well-supported track records.
