Water & Wastewater Treatment Equipment Serving Los Angeles, CA
Precision lime feed, biosolids stabilization, drying, and truck loading systems engineered by RDP Technologies for Los Angeles-area municipal facilities.
Trusted Process Equipment for Los Angeles 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. Los Angeles-area utilities count on RDP for clean, accurate, reliable systems that are simple and easy to maintain.
Custom Engineering & Process Equipment Support Serving Los Angeles
Los Angeles operates some of the most complex water and wastewater infrastructure in the western United States, with treatment facilities serving millions of residents across a sprawling service area. RDP Technologies brings over 45 years of custom process equipment engineering experience to projects throughout LA County, designing solutions that fit real site conditions rather than forcing a one-size-fits-all approach.
As a wastewater treatment equipment manufacturer that handles design, fabrication, and controls under one roof, we work closely with municipal engineers and consulting firms to scope equipment that meets California’s strict regulatory environment. Our intelligent control systems can be customized for SCADA integration, remote monitoring, and the detailed reporting that California utilities routinely require.
We support new installations, retrofits of aging equipment, and process troubleshooting for facilities from the San Fernando Valley down through the South Bay. Practical technologies that simply perform is the standard we hold ourselves to, whether the scope is a single feed system upgrade or a full biosolids treatment line. Los Angeles plants get a partner who understands that seismic considerations, footprint constraints, and operator workflows all shape what a successful project actually looks like.
Biosolids Drying Systems for Los Angeles Wastewater Plants
Long hauling distances and the high cost of moving wet sludge cake across Southern California make biosolids drying systems an attractive investment for Los Angeles wastewater plants. The RDP-Fenton wastewater sludge dryer uses a repeating batch process that adjusts drying time to match incoming feed conditions, which is a real advantage when sludge cake solids concentration varies from day to day.
Batch sludge drying equipment handles these fluctuations far better than continuous systems, which can struggle when dewatering output shifts. Operators consistently report that the system is simple to run and requires less daily attention than competing technologies on the market. The end product is dramatically reduced in volume and weight, cutting trucking costs significantly and opening up beneficial reuse opportunities in agricultural and energy markets common throughout California.
When paired with upstream RDP lime feed equipment or storage systems, LA-area plants get a fully integrated biosolids handling line from a single source. Long service life and low maintenance demand were the guiding principles behind the design, and that focus shows up clearly in long-term operating data from installed sites.
Lime Slaking & Feed Systems for Los Angeles Water Treatment Facilities
Los Angeles water treatment facilities serve a vast and varied customer base, with source water ranging from the State Water Project to local groundwater basins requiring careful pH adjustment and softening. RDP Technologies has built its reputation on lime slaking systems and lime feed systems that handle this work with the precision large municipal operations demand.
Our Tekkem lime slakers for water treatment apply load cell technology to deliver a precise weight of quicklime into a precise weight of water, optimizing the slaking reaction at the 180°F to 190°F temperature range where the chemistry works best. This weight-based approach is the foundation of precision lime dosing systems that maintain accuracy across changing plant conditions throughout the day.
Operators in LA appreciate that the same Tekkem unit can be converted to a hydrated lime feed system without mechanical modifications, providing flexibility as lime market dynamics shift on the West Coast. The continuous lime slurry delivery loop combined with pinch valve and flow meter dosing supports accurate delivery to multiple application points within a single facility. Maintenance demands stay low thanks to a reaction tank design with just one moving part, an important consideration for utilities running 24/7 operations.
Biosolids Storage & Precision Truck Loading Systems
Greater Los Angeles produces substantial volumes of biosolids daily, and getting that material out of the plant cleanly and on tight hauler schedules is a recurring operational priority. RDP Technologies designs biosolids storage systems and precision truck loading systems that automate the path from dewatering equipment to the truck bay.
Live bottom bin storage uses moving floor technology to keep sticky sludge cake flowing reliably, preventing the bridging and rat-holing problems that plague conventional hoppers. The precision truck loading system handles sludge cake truck loading automatically and quickly, typically completing a load within minutes while staying accurate to within a couple hundred pounds of the operator’s target weight.
Three decades and around three hundred biosolids conveying equipment projects have refined a layout that keeps trucks neat, clean, and out the gate on schedule. Because the system runs automatically, plant staff are freed from constant attendance at the loadout, redirecting labor to higher-value tasks. For high-throughput LA-area facilities managing heavy daily hauler traffic, this reliability translates directly into reduced overtime and smoother logistics overall.
Biosolids Lime Stabilization & Pasteurization Solutions in Los Angeles, CA
Land application and beneficial reuse of biosolids remain important disposal pathways for many Los Angeles, CA region utilities, which makes proven pathogen reduction equipment essential. RDP Technologies has been delivering biosolids lime stabilization solutions since the EPA 503 regulations first took effect, with a deep portfolio of installations supporting both Class A biosolids treatment and Class B biosolids stabilization.
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 and references on multiple continents. EnVessel uses supplemental heat in combination with lime rather than relying on heavy overdosing, keeping the chemical demand reasonable while reliably hitting time, temperature, and pH targets for full pathogen kill.
The Enhanced Pasteurization process meters biosolids into a sealed sequencing batch reactor where lime brings the pH above 12 and controlled heating completes the disinfection cycle. Both options qualify as wastewater pathogen reduction equipment recognized by regulators and supported by decades of published case studies. For Southern California municipalities planning upgrades or evaluating new biosolids strategies, these are well-documented, regulator-tested pathways.
