Lime Slaking & Feed Systems for Newark Water Treatment Facilities
The Newark Department of Water and Sewer Utilities operates the Pequannock Water Treatment Plant, drawing on a chain of forested watershed reservoirs including Charlotteburg, Oak Ridge, Canistear, and Clinton to supply drinking water to Newark and several neighboring communities. This surface water runs naturally soft and slightly acidic, which puts pH adjustment, alkalinity recovery, and corrosion control at the center of daily treatment. Those priorities came into sharp focus during the citywide lead service line program and the corrosion control changes that followed, work carried out under the federal Lead and Copper Rule. Precise, dependable lime feed is fundamental to holding finished water chemistry stable across a large and aging distribution network, and RDP designs lime slaking and feed systems built for exactly that level of control.
The Tekkem family of lime slakers uses 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 approach supports precision dosing with slurry concentration adjustable from one percent up to thirty percent to match plant conditions.
The same Tekkem platform runs as a hydrated lime feed system with no physical changes, giving operators flexibility as lime supply and pricing shift across the New York and northern New Jersey market. A continuous slurry loop paired with pinch valve and flow meter dosing delivers accurate feed at multiple application points, and with a single moving part inside the reaction tank, maintenance stays low and predictable for plants running around the clock.

Biosolids Storage & Precision Truck Loading Systems
The Passaic Valley Sewerage Commission operates the Newark Bay treatment plant, one of the largest wastewater facilities in the country, handling flow from Newark and roughly 47 additional municipalities across Essex, Hudson, Bergen, Passaic, and Union counties. A plant at that scale generates enormous daily biosolids volumes, and with limited in-state land application, most of that material moves by truck to out-of-state outlets. Dependable storage and loadout equipment is essential to keeping a hauling program of that size running on schedule through the full range of northern New Jersey weather. RDP Technologies engineers biosolids storage systems and precision truck loading systems that automate the entire flow from dewatering through to the departing truck.
Moving floor technology built into live bottom bin storage keeps sticky sludge cake flowing reliably, eliminating the bridging and rat-holing that plague conventional steep-walled hoppers. Sludge cake loading runs automatically through the precision truck loading system, with most loads finished in minutes and held to within a couple hundred pounds of the operator's target weight.
Three decades and roughly three hundred biosolids conveying installations have refined a layout that keeps trucks clean, departure times predictable, and operator involvement at the bay minimal. Because the cycle runs without constant attendance, Newark-area plant staff can shift labor toward higher-value work across the facility. For an operation coordinating steady truck rotations to distant disposal and reuse sites, that automation directly lifts daily throughput and holds down overtime.

Biosolids Lime Stabilization & Pasteurization Solutions in Newark, NJ
New Jersey has been among the most aggressive states in the country on PFAS, with NJDEP setting some of the earliest maximum contaminant levels nationally, and that regulatory posture continues to shape how biosolids are managed across the state. With in-state land application limited and disposal outlets under steady pressure, Class A treatment pathways are increasingly valuable for the market flexibility they open up. RDP Technologies has delivered EPA 503 compliant lime-based solutions since the federal rules were first written, supporting both Class A biosolids treatment and Class B biosolids stabilization at facilities throughout the Mid-Atlantic and Northeast.
The EnVessel Pasteurization system 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 consistently hitting the time, temperature, and pH targets 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 Newark-area facilities weighing capital upgrades against NJDEP oversight and a tightening PFAS landscape, these are regulator-recognized options with long, well-documented track records.

Biosolids Drying Systems for Newark Wastewater Plants
With most northern New Jersey biosolids traveling long distances to out-of-state disposal and reuse outlets, hauling weight is one of the largest and most controllable line items a plant carries. Biosolids drying gives Newark-area facilities a direct way to cut that tonnage while opening access to higher-value end products. The RDP-Fenton wastewater sludge dryer runs on a repeating batch cycle that lets drying time be tuned to the natural variation in cake solids coming off the dewatering line.
Batch sludge drying equipment absorbs those upstream swings cleanly, where continuous-flow dryers often stumble when feed quality shifts without warning. Operators in the field consistently note how little daily attention the system needs once a stable recipe is set.
The dried product comes out sharply reduced in volume and weight, lowering trucking costs and opening pathways into fertilizer, soil amendment, and energy recovery markets across the region. Paired with upstream RDP lime feed or storage equipment, a Newark plant gains a fully integrated biosolids line backed by one manufacturer with consistent controls and ongoing support. Long service life and simple operation drove the design from the start, and that shows clearly in performance data from installed sites nationwide.

Custom Engineering & Process Equipment Support Serving Newark
Water and wastewater infrastructure across the Newark region operates on some of the most constrained and heavily used sites in the Northeast, hemmed in by dense urban development, the Passaic River, and Newark Bay. Facilities here contend with coastal storm surge and flooding, the legacy of combined sewer systems, and the reality of serving one of the densest population corridors in the nation. RDP Technologies brings over 45 years of custom process equipment engineering to capital projects across Essex, Hudson, Union, and the surrounding northern New Jersey counties.
As a manufacturer that handles design, fabrication, and controls programming under one roof, we adapt to existing tankage, tight urban footprints, and established 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 the New Jersey Department of Environmental Protection and EPA Region 2 oversight.
We work 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 behind every project we deliver. Newark-area facilities benefit from a single accountable manufacturer that designs, builds, and stands behind its equipment for the long haul.
