Dutch company chooses centrifuge case to combat corrosion & safety concerns
Lubrizol, a highly advanced chemicals manufacturer, was experiencing severe corrosion in the case of one of its decanter centrifuges. In theory, the centrifuge’s titanium grade 2 case and rotating assembly should have been able to withstand the hydrochloric acid that passed through the centrifuge. However, changing process conditions (elevated temperatures and concentrations) were causing substantial corrosion problems and increasing maintenance costs. In addition to meeting its functional criteria, Lubrizol needed a solution that was:
Hymax Grip joins and restrains a wide range of piping types and diameters. Its radial gripping system is suitable for both metal and plastic pipes. Its patented gasket transforms the pipe joint into a flexible connection, allowing dynamic deflection, and reduces future pipe cracks and breaks.

Nova Scotia utility uses subsurface direct discharge unit to reduce costs & improve water quality
Nova Scotia’s Halifax Regional Water Commission (HRWC), also known as Halifax Water, provides potable water, wastewater and storm water services to the Halifax Regional Municipality. Halifax Water currently manages eight watersheds as well as three groundwater sources, which collectively supply potable water to more than 86,000 customers. Water is delivered via 82,334 service connections, 31,878 of which are located within its east region. Included within the distribution system are 23 Department of Environment sampling stations.
The Problem
The Freeflo non-sparking base elbow rail system is designed for the simple installation and removal of submersible sewage pumps. The non-sparking design assures safety in wastewater applications that can be hazardous and require explosion-proof protection. These systems range from 1.25 to 6 in. and include a bronze or bronze-plated pullout flange. They are ready to ship in 24 hours.
The Unasphere is a precision molded expansion joint that will minimize water hammer or hydraulic shock in any system. The streamlined, flowing arch reduces turbulence and allows for smooth, quiet flow. All joints through 12 in. are rated for 26-in.-Hg vacuum and 225 psi.
Product provides a reduction of growth in excess of 99%
The root cause of microbially induced corrosion (MIC) of concrete has been well documented—it is an acid that is produced by a bacterium called Thiobacillus thiooxidan. This species lives on the concrete, consumes sulfur from hydrogen sulfide gas and then excretes a very harsh acid. The acid attacks the concrete, causing it to erode. There are three distinct phases of the corrosion process: Phase one is carbonation of the concrete, a naturally occurring process; phase two is the biological attachment phase; and phase three is the acid corrosion phase.
Products are suitable for the protection of electrical systems in wastewater applications
Stainless conduit and conduit systems from Calbrite, a division of Calpipe Industries Inc., is manufactured in type 304 and 316 stainless to meet stringent sanitary conditions. The company’s UL-listed stainless conduit is suitable when corrosive applications exceed the limitations of aluminum, rigid and PVC-coated conduit. Calbrite stainless steel rigid conduit is available in ½-in. to 6-in. diameters and includes one coupling with each length purchased.
Calbond manufactures a full line of aluminum rigid PVC coated conduit and fittings. Lighter and easier to handle than steel galvanized PVC coated conduit systems, Calbond’s aluminum PVC coated systems provide savings in installation while providing excellent corrosion protection.
Maryland WRF shows submersible mixers offer performance longevity
In Maryland, a Water Reclamation Facility (WRF) replaced the motors of 12 Landia submersible mixers after nearly 20 years of service; however, the original stainless steel propellers are still intact and set for another lengthy spell in the plant’s oxidation ditches.
Products are suitable for harsh environments in wastewater treatment facilities
Calbond PVC coated conduit and conduit fittings are designed and manufactured to high quality standards and are fully compliant to UL6, NEMA RN-1 and ANSI C80.1 standards. In extremely corrosive environments – such as those in wastewater treatment plants where the PVC may accidentally get breached or compromised – it is critical to have the additional protection of PVC coating over the underlying zinc.
Hymax Grip joins and restrains a wide range of piping types and diameters. Its radial gripping system is suitable for both metal and plastic pipes. Its patented gasket transforms the pipe joint into a flexible connection, allowing dynamic deflection, and reduces future pipe cracks and breaks.
TB Wood’s line of L-Jaw couplings has been expanded to include a larger range of bore sizes, as well as new aluminum and stainless steel hubs. The couplings are part-for-part interchangeable with industry-standard designs. They are easy to install and require no lubrication or maintenance, while providing good vibration isolation and chemical resistance. Sizes are offered with torque ratings up to 6,228 in. lb and bore sizes up to 27/8 in. diameter. Couplings can accommodate up to 1 degree of angular misalignment and have an operating temperature range of -60˚ to 250˚F.
The AquataFlex series of protective coatings includes the AquataFlex 505 and 506, versatile novalac epoxy polyurethane hybrids. They are environmentally friendly, 100% solids, and safe for potable water, food and industrial applications. The series exhibits fast cure times and the flexibility of a polyurethane with the increased chemical resistance of an epoxy.
Scott Air Force Base utilizes lining system to aid in rehab project
From the Wright Brothers’ first successful flight in 1903 at Kitty Hawk, N.C., to an American landing on the moon, the U.S. has dominated the global airspace. Construction of what would become Scott Air Force Base (SAFB), named after aviation crash victim Cpl. Frank Scott, began in southwest Illinois (approximately 20 miles east of St. Louis) in June 1917, only two months after the U.S. entered World War I. Serving primarily as an aeromedical field, SAFB was recommended to become the general headquarters of the Air Force in 1938.
