Fedjetting (Jiangsu Fedjetting Tech Co., Ltd.), a leading innovator in industrial ultra-high-pressure (UHP) waterjet technology, has officially announced its complete integrated solution for structural concrete rehabilitation and selective demolition. The newly showcased platform combines Fedjetting’s heavy-duty mobile diesel pump trailer, Conjet hydrodemolition robotic lances, and a dedicated multi-stage wastewater treatment and recirculation module—delivering maximum productivity while meeting stringent environmental zero-discharge mandates.
Traditional mechanical concrete demolition relying on jackhammers and heavy breakers causes micro-cracking across remaining sound concrete structures, severely compromising structural integrity. Furthermore, mechanical methods generate massive silica dust clouds, high noise levels, and require manual labor operating in high-risk zones.
Hydrodemolition utilizes high-pressure water jets to erode damaged or deteriorated concrete selectively without vibrating or micro-fracturing the underlying rebar and solid matrix. Fedjetting’s new mobile system addresses both power delivery and environmental sustainability by seamlessly linking high-efficiency water power, robotic precision, and localized wastewater treatment.
Fedjetting UHP Mobile Trailer Pump Unit:
Engineered for continuous heavy-duty field operation, Fedjetting’s diesel-driven mobile pump unit delivers continuous operating pressures up to 2,800 bar (40,000 psi) with ultra-durable fluid ends, stainless steel plungers, and automated pressure monitoring for flawless fluid flow.
Conjet Robotic Hydrodemolition Operator:
Equipped with advanced multi-axis positioners and automated oscillation control, Conjet robots execute exact cutting depths and patterns across horizontal decks, vertical walls, and overhead soffits without exposing personnel to hazards.
Multi-Stage Wastewater Treatment Trailer:
A closed-loop filtration unit capable of receiving blast slurry, neutralizing pH levels, removing suspended solids down to sub-micron thresholds, and continuously feeding cleaned water back into the UHP suction line.
Mobile Logistics & Rapid Deployment:
All system modules are integrated into compact road-ready trailer chassis, enabling rapid setup on bridge decks, parking structures, hydro-electric dams, and tunnel linings within 30 minutes of arrival.
A critical breakthrough of the Fedjetting concrete hydrodemolition system is its zero-discharge multi-stage water management sequence:
Slurry Containment & Vacuum Collection: As the Conjet robot strips the concrete matrix, high-powered vacuum recovery hoods instantly collect water slurry, aggregate dust, and concrete chips.
Coarse Solids Separation (Stage 1): Primary mechanical shakers and hydrocyclones remove heavy aggregate fractions and particles greater than 100 microns into portable disposal bins.
Flocculation & Settling (Stage 2): Polymer dosing tanks accelerate the precipitation of fine suspended concrete sludge (calcium hydroxide / silica solids) out of suspension.
pH Neutralization (Stage 3): Automated CO₂ or acid injection neutralizes highly alkaline hydrodemolition runoff water from pH 12–13 down to a neutral pH 7.0–8.0.
Micro-Filtration & UHP Return (Stage 4): Multi-stage cartridge filters clean water down to <5 microns, ensuring crystal-clear supply water feeds back directly into the Fedjetting high-pressure pump inlet without damaging plungers or valves.
