High pressure water jetting remains an effective means of removing foreign and unwanted materials from a wide range of industrial applications. Water jetting at pressures of 10,000 to 40,000 psi can provide rapid and thorough results. Effluent control and filtration can be combined to provide a total solution even for hazardous material removal (ie. lead, asbestos, etc.) from steel or concrete.
Hennigan Engineering Co., Inc. has addressed these concerns in an effort to provide superior cleaning alternatives without the use of chemicals and abrasive cleaning agents. We have enhanced the efficiency of manually operated surface decontamination techniques and developed remotely- operated decontamination systems for work in hazardous environments and confined spaces.
The unique challenges which we have encountered have led to innovative solutions. Our specialized equipment has been used for a wide variety of applications, including the removal of asbestos coatings from steel and concrete, oil and asphalt spills from roadways and drainage systems, hazardous product residual from tanks, piping, reactor vessels, and high level radiological contamination from critical nuclear power plant components.
Custom designed N2 gas regulated pressure control systems are used on all of our equipment to provide a fully positive shut-off water delivery system which can cut in half the volume of effluent water generated during the decontamination process. Water recovery options, including submicron level filtration and oil/water separators, can be utilized to remove lead, asbestos fibers, oil, grease, and other hazardous substances from the effluent stream, often meeting state regulations for disposal into municipal waste water treatment systems.
