Water & Wastewater Treatment Equipment Serving Chicago, IL

Precision lime slaking, biosolids stabilization, drying, storage, and truck loading systems engineered by RDP Technologies for Chicago-area municipal facilities.

Trusted Process Equipment for Chicago 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. Chicago-area utilities count on RDP for clean, accurate, reliable systems that are simple and easy to maintain.

Biosolids Storage & Precision Truck Loading Systems

Chicago handles one of the largest biosolids volumes in the country, and moving that material out of the plant cleanly and on schedule is a daily operational challenge. RDP Technologies designs biosolids storage systems and precision truck loading systems that automate the entire flow from dewatering equipment to the hauler at the loadout bay.

Our live bottom bin storage uses moving floor technology to prevent bridging and rat-holing common with sticky sludge cake, keeping the material flowing reliably even during cold Chicago winters. The precision truck loading system can load a typical truck within minutes, with sludge cake truck loading accuracy held to within a couple hundred pounds of the operator’s set point. Three decades and roughly three hundred biosolids conveying equipment projects have shaped a layout that keeps trucks neat, clean, and out the gate quickly.

The whole sequence runs automatically, so operators are freed up rather than tied to the bay during every load. For municipal facilities in Cook County managing high daily throughput and tight hauler windows, that consistency translates directly into lower labor cost and fewer scheduling headaches.

Biosolids Drying Systems for Chicago Wastewater Plants

For Chicago wastewater plants looking to dramatically reduce hauling weight and produce a marketable end product, RDP-Fenton biosolids drying systems offer a straightforward path to Class A dried biosolids. Our wastewater sludge dryer operates on a repeating batch basis, which lets operators vary drying time to match changes in sludge cake solids concentration and feed characteristics from day to day.

Unlike continuous systems that struggle when feed conditions shift, batch sludge drying equipment adapts to whatever the dewatering line delivers without constant babysitting. As one operator put it, with the RDP-Fenton dryer there is simply less to mess with on a daily basis. The dried product is dramatically reduced in volume and weight, which cuts transportation costs and opens up beneficial reuse options like fertilizer and soil amendment markets across northern Illinois.

The design pairs well with upstream RDP lime feed and storage equipment, giving Chicago-area plants a fully integrated biosolids treatment line from a single manufacturer. Reliability and ease of operation were the guiding principles behind the system, and that shows up in long service life and low maintenance demand.

Lime Slaking & Feed Systems for Chicago Water Treatment Facilities

Chicago’s drinking water plants pull from Lake Michigan and rely on precise pH adjustment and softening to deliver clean, balanced water to millions of residents and businesses every day. RDP Technologies has spent over 45 years building lime slaking systems and lime feed systems that handle this work cleanly, accurately, and reliably.

Our Tekkem lime slakers for water treatment use load cells to add a predetermined amount of quicklime to a predetermined amount of water, holding the slaking reaction between 180°F and 190°F where the chemistry runs best. That weight-based control is what makes precision lime dosing systems possible, with the slurry concentration tunable anywhere from one percent up to thirty percent depending on plant needs.

The same unit can switch to a hydrated lime feed system without physical modifications, giving Chicago operators flexibility to adapt to lime market pricing or local supply preferences. A precision dosing sub-system uses a pinch valve and flow meter to deliver accurate dosage at multiple application points, and dosing can be automated to follow plant flow rates throughout the day. With only one moving part inside the reaction tank, maintenance stays infrequent and predictable, which is exactly what large municipal water operations need.

Biosolids Lime Stabilization & Pasteurization Solutions in Chicago, IL

Meeting EPA 503 regulations for biosolids land application in the greater Chicago, IL region requires reliable pathogen reduction, and RDP Technologies has been at the center of this work since the rules were first written. Our biosolids lime stabilization equipment supports both Class A biosolids treatment and Class B biosolids stabilization, giving Cook County, DuPage, and Will County facilities options that match their end-use goals.

The EnVessel Pasteurization biosolids pasteurization system is one of the most widely deployed Class A processes in the country, with over 70 operating installations across the United States. EnVessel combines lime with supplemental heat rather than overdosing with lime alone, which keeps chemical use reasonable while still hitting time-temperature-pH targets for full pathogen kill.

The Enhanced Pasteurization process takes this further, metering biosolids into a sealed sequencing batch reactor where time, temperature, and chemistry are precisely controlled to produce a stable end product. As wastewater pathogen reduction equipment, both processes are well documented through decades of case studies from municipalities across the country. For Illinois utilities planning upgrades or new construction, these are proven, regulator-recognized options.

Custom Engineering & Process Equipment Support Serving Chicago

No two treatment plants are identical, and Chicago-area facilities especially tend to carry decades of layered infrastructure that has to be worked around rather than ripped out. RDP Technologies offers custom process equipment engineering that fits real-world site constraints, existing tankage, and operator workflows rather than forcing a generic package onto a difficult footprint.

As a wastewater treatment equipment manufacturer with over 45 years of field experience, we bring practical insight to every project, from initial process selection through startup and long-term support. Our team works directly with plant engineers, consulting firms, and operations staff to scope equipment that performs reliably on day one and stays maintainable for the decades that follow.

The same intelligent control systems that drive our Tekkem slakers and Fenton dryers can be tailored for site-specific instrumentation, SCADA integration, and reporting requirements common across Illinois municipal systems. We also support upgrades to existing RDP installations, replacement parts, and process troubleshooting for facilities throughout the Midwest. Whether the project is a single feed system retrofit or a full biosolids handling line, the goal is the same: clean, accurate, reliable equipment that simply performs. Chicago plants get the benefit of a manufacturer that designs, builds, and stands behind the equipment under one roof.
