Water & Wastewater Treatment Equipment Serving Houston, TX
Precision lime feed, biosolids stabilization, drying, storage, and truck loading systems engineered by RDP Technologies for Houston-area municipal facilities.
Trusted Process Equipment for Houston 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. Houston-area utilities count on RDP for clean, accurate, reliable systems that are simple and easy to maintain.
Biosolids Lime Stabilization & Pasteurization Solutions in Houston, TX
Biosolids handling across the Houston, TX region operates at a scale that demands proven pathogen reduction technology, and RDP Technologies has been delivering compliant lime-based solutions since the EPA 503 rules were first written. Our biosolids lime stabilization product line supports both Class A biosolids treatment and Class B biosolids stabilization, giving Gulf Coast utilities flexibility based on disposal pathways and beneficial reuse strategies.
The EnVessel Pasteurization biosolids pasteurization system stands as one of the most widely adopted Class A processes in the country, with more than 70 installations operating across the United States. EnVessel pairs lime with supplemental heat instead of relying on heavy lime overdosing, keeping chemical demand reasonable while reliably hitting the time, temperature, and pH thresholds required for full pathogen kill.
The Enhanced Pasteurization option carries the cycle into a sealed sequencing batch reactor, where lime drives pH above 12 and controlled heating completes the disinfection step. Both pathways serve as proven wastewater pathogen reduction equipment, backed by decades of published case studies and operational data from municipalities nationwide. For Houston-area facilities planning capital upgrades or rethinking their biosolids strategy, these are regulator-recognized options with strong track records.
Biosolids Drying Systems for Houston Wastewater Plants
Houston wastewater plants manage some of the largest biosolids volumes in Texas, and reducing hauling weight is one of the most direct levers available for controlling long-term operating costs. The RDP-Fenton wastewater sludge dryer runs on a repeating batch cycle that allows drying time to be adjusted to match natural variation in sludge cake solids concentration coming off the dewatering line.
Batch sludge drying equipment handles those swings cleanly, whereas continuous-flow dryers often struggle when upstream output shifts unexpectedly. Operators in the field have repeatedly highlighted how little daily attention the system requires once a stable recipe is in place.
The dried product comes out significantly reduced in volume and weight, lowering trucking costs and opening pathways into fertilizer, soil amendment, and energy recovery markets across the Texas Gulf Coast. Pairing the dryer with upstream RDP lime feed or storage equipment gives Houston wastewater plants a fully integrated biosolids handling line backed by a single manufacturer with consistent controls and ongoing support. Long service life and ease of operation were the design priorities from the start, and that focus shows clearly in real-world performance from installed sites across the country.
Biosolids Storage & Precision Truck Loading Systems
The Houston region generates substantial daily biosolids volumes, and efficient material handling at the loadout bay is essential to keeping the broader hauling program running smoothly through Texas heat and humidity. RDP Technologies engineers biosolids storage systems and precision truck loading systems that automate the entire flow from dewatering equipment through to the departing truck.
Moving floor technology built into our live bottom bin storage keeps sticky sludge cake moving consistently, avoiding the bridging and rat-holing that frequently plague conventional steep-walled hoppers. Sludge cake truck loading runs automatically through the precision truck loading system, with most loads completed in a matter of minutes and held to within a couple hundred pounds of the operator’s set point.
Three decades and roughly three hundred biosolids conveying equipment installations have refined a layout that keeps trucks clean, departure schedules predictable, and operator involvement minimal at the bay. Because the cycle runs without constant attendance, Houston plant staff can redirect labor toward higher-value tasks elsewhere in the facility. For utilities operating heavy hauler rotations year-round, that automation translates directly into fewer scheduling headaches and reduced overtime spend.
Lime Slaking & Feed Systems for Houston Water Treatment Facilities
Houston’s drinking water system draws from surface supplies including the Trinity and San Jacinto river basins along with major regional reservoirs, all of which require careful pH adjustment and softening before reaching customers. RDP Technologies designs lime slaking systems and lime feed systems engineered for the precision and reliability that high-volume Texas municipal operations require.
The Tekkem family of lime slakers for water treatment 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 temperature window. This weight-based control approach is what enables precision lime dosing systems with slurry concentration adjustable anywhere from one percent up to thirty percent based on plant requirements.
The same Tekkem unit converts to function as a hydrated lime feed system without any mechanical changes, giving Houston operators flexibility as lime supply conditions shift across the Gulf Coast region. A continuous slurry delivery loop paired with pinch valve and flow meter dosing supports accurate delivery to multiple application points throughout a facility. With only one moving part inside the reaction tank, maintenance demands stay low and predictable for plants running around the clock.
Custom Engineering & Process Equipment Support Serving Houston
Houston’s water and wastewater infrastructure has grown alongside one of the fastest-expanding metropolitan regions in the country, and new equipment frequently has to fit into facilities that have been expanded multiple times over the years. RDP Technologies brings over 45 years of custom process equipment engineering experience to projects across Harris County and the surrounding Gulf Coast region.
As a wastewater treatment equipment manufacturer that handles design, fabrication, and controls programming under one roof, we adapt to existing tankage, demanding site constraints, and established operator workflows rather than forcing a generic package onto a difficult footprint. Our intelligent control platforms integrate cleanly with SCADA systems and meet the detailed reporting requirements typical of TCEQ and EPA Region 6 oversight.
We work directly with municipal engineers, consulting firms, and plant operations staff from initial scoping through commissioning and long-term technical support. Robust equipment, dependable process performance, and practical technologies that simply perform have guided every project we deliver. Houston-area facilities benefit from working with a single accountable manufacturer that designs, builds, and stands behind the equipment for decades.
