Arch Chemicals, Inc., a Lonza company, is a complete water solutions provider, offering state-of-the-art sanitizers, feeder systems, and support services for municipal, industrial, and commercial applications.
While the debate rages on as to whether fracking poses a risk to water quality, a new desalination technique addresses two other environmental concerns: water scarcity and greenhouse gas (GHG) emissions. Developed by researchers at the University of British Columbia (UBC), the breakthrough technology uses excess carbon dioxide created in the fracking process to desalinate the process water, making it available for water reuse. It also generates chemicals — hydrochloric acid and carbonate salts — that are valuable for many industrial applications.

Summer is here, and with it comes rising temperatures and energy costs. Future-minded water utilities realize any decision made today to help offset future energy consumption is both economically and environmentally wise. With that in mind, utilities across the country are desperately searching for green products and innovations to help them conserve precious resources in the future, and iron pipe is one tool that can help them accomplish this.

Scheid Vineyards, located in Greenfield, CA, captures wastewater influent from the winery in three aeration ponds to supply the needed biological oxygen demand (BOD) to treat the effluent prior to being used for irrigation. The existing aeration system was inefficient and maintenance-intensive, leading the facility to explore alternative solutions.

Decentralized wastewater treatment technologies, such as the MicroFAST Systems, use simple, low-cost, and robust technology to solve a gamut of onsite wastewater treatment issues. With conventional, “decentralized” septic systems, only 10 percent to 40 percent of treatment actually occurs in the tank. Whereas, advanced wastewater treatment systems, such as the FAST system, do 90 percent to 95 percent of the treatment before discharging to the environment.

A Midwestern industrial plant has a cooling tower that supplies cooling water to air compressors, oil coolers, air dryers, and various types of process equipment. In an effort to cut operating costs, the plant looked for ways to decrease their cooling tower makeup water, sewer, and chemical requirements.

Air/gas mass flow meters find a variety of applications in many of today's large urban water treatment plants, for both clean water and wastewater. From measuring disinfection gases to controlling air or gas flow in digesters and aeration systems, the proper application, installation, and operation of mass flow meters improves process efficiency as well as end product quality while at the same time reducing plant operating costs.

By managing efficiency and effectiveness, all aspects of operations can be optimized to be as lean, and green, as possible. As costs for chemicals, energy, staff, and parts climb, optimizing will be critical. So how is this done? Many facilities have a SCADA system, or an ODMS system as their highest level software. Neither of these is designed to find an operation’s most efficient and effective operating point.

Because blowers are run continuously, energy costs associated with the aeration basin are typically the largest expense for wastewater facilities. The wastewater treatment plant in the city of Grand Rapids was looking to reduce aeration energy costs and recently upgraded the facility with a Hach Real-Time Control System. The result was a nearly $60,000 energy efficiency incentive payment from Consumers Energy, and the plant is now on track to save the city more than 735,000 kilowatt hours of electricity and $62,000 annually.
