††Revitalize Your Infrastructure: Avoid Costly Wastewater Tank Replacement Replacing wastewater tanks can be a costly and disruptive process, involving major construction, downtime, and environmental impact. A recent article from the Whittier Daily News highlights Ridgeline Energy Services in Santa Fe Springs, CA, as they begin dismantling 19 old tanks at their wastewater treatment facility. Located on the former Powerline Oil Co. refinery site, the plant has struggled with odor complaints due to mixing between wastewater and residual sludge. Several of the tanks had leaks, allowing hazardous gases like hydrogen sulfide to escape through roof openings, affecting air quality but not posing a toxic risk. Each tank weighs 28 tons and holds up to 16,800 gallons of wastewater. The metal will be recycled, and the solution for the odor problem is complete removal rather than repair. A Global Challenge This issue isn’t unique to one location—steel tanks worldwide face corrosion and structural failure over time. While temporary fixes like steel plates may work initially, they often lead to more problems down the line. An effective, long-term alternative is the use of Carbon Fiber Reinforced Polymer (CFRP) solutions, such as HJ3’s CarbonSeal system. Replacing large-scale tanks can cost millions and have a huge environmental footprint. For example, producing one ton of steel requires about 60,000 gallons of water. Replacing Ridgeline’s 19 tanks would use an estimated 32 million gallons of water. Instead, using advanced composite materials offers a sustainable and cost-effective solution. A Success Story: NRG Energy HJ3’s CarbonSeal system has proven to be a game-changer. One notable success was with NRG Energy, one of the largest power generation companies in the U.S. At one of their facilities, a 2-million-gallon wastewater tank was leaking badly. Previous attempts using steel plates only made things worse, creating thousands of new holes in the walls and floor. The project started with repairing the tank’s walls, floors, and support columns. During preparation and hydro-blasting, 4,300 additional holes were discovered, requiring further reinforcement. Steel plates were used to cover these areas, and then HJ3’s CarbonSeal carbon fiber system was applied. Surfaces were sandblasted, cleaned, inspected, and primed to prevent rust before the high-modulus paste and carbon fiber layers were added. A chemical-resistant topcoat ensured long-term protection. A Sustainable Solution By choosing to repair instead of replace, NRG extended the life of their tank by an estimated 30 years. This approach saved them significant costs and reduced environmental impact. Compared to full replacement, the project led to a 90% reduction in energy use, 96% fewer CO2 emissions, and the conservation of 60 million gallons of water. Overall, NRG saved over $3 million—equivalent to 75% in savings. Whether you’re dealing with aging infrastructure or looking for eco-friendly repair options, HJ3’s CarbonSeal system offers a smart, sustainable path forward.

Double column machining center also called dual column machining center. Double column machining center is a type of machining center with two independent columns. This structure consists of two columns and a crossbeam, forming a stable portal structure that enhances the overall rigidity and stability of the machine tool. The design of the dual column machining center enables the machine tool to adjust the position of the columns according to the machining requirements of the workpiece, thereby expanding the machining range and improving machining flexibility. This type of machining center is widely used in aerospace, automotive manufacturing, mold processing, and other fields, especially when processing large and complex shaped workpieces. There is a crossbeam in the middle of the double columns, and the overall structure is a large machining center machine with a portal frame composed of double columns and top beams, suitable for processing large parts
