A Southeast manufacturer of printed circuit boards for the defense and medical industries was experiencing poor and inconsistent water quality on their board washing process, which utilized a deionization (DI) system from a local water treatment company. The water quality issue was resulting in re-work of off-spec boards, additional labor to re-process boards that failed quality control review, and higher costs overall.

When an aerospace structure manufacturer aimed to limit POTW discharge, Evoqua implemented a rinsewater recycling system using ion exchange, reducing manual treatment, lowering costs, and maintaining high-quality standards.

Updated State and Federal environmental regulations led to a shortened project timeline for a facility that needed a Low Volume Wastewater (LVWW) system. Because the regulation prevented the use of the ash impoundment after the deadline, the facility needed to divert all low volume wastewater flows entering the impoundment from the deadline date to the time a permanent LVWW system could be installed and operational.

A southern mining company was developing salt dome gas storage facilities that use water to mine salt from the domes shaping them so they can be used to store natural gas inside under high pressures. The raw water used for the mining process contained high levels of iron (5-8 ppm) resulting in equipment fouling and high maintenance costs.

Stone countertop company, Surface Technology, Inc. of Elkridge, Maryland, knew they needed a larger filter press to improve the efficiency of the company's production system and reduce costs. What they didn't know was how the new press was going to improve their whole system.

After new lower discharge limits for cadmium were introduced, a U.S. metal finishing facility providing aerospace and oil industry services reached out to Evoqua for help. Evoqua conducted treatability testing and filtration analysis, then implemented a selective media ion exchange solution using SCU vessels in a worker/polisher configuration to consistently meet strict ppb-level discharge requirements and restore compliance.

Facing severe water shortages, a PCB manufacturer implemented wastewater ion exchange to recycle rinsewater, ensuring consistent water quality and uninterrupted production.

After an unexpected fire caused extensive damage to their manufacturing facility, a Southeast Aerospace metal finishing company reached out to Xylem for help. Xylem rapidly deployed a turnkey solution, implementing service deionization (SDI) for incoming water and wastewater ion exchange systems to restore treatment capabilities and support continued production during rebuilding.

An aerospace manufacturer used ion exchange to treat cadmium cyanide rinse waters, achieving compliance without hazardous chemicals while meeting tight timelines and budget constraints.

As part of a major highway improvement project, construction dewatering was required in an area in order to pour footings for an overpass. Contaminated water from an adjacent Superfund site was drawn into the dewatering stream, requiring treatment of the contaminated water stream prior to discharge on-site.

A global firefighting equipment manufacturer used a plant-based, environmentally friendly coolant in their machine shop that was mixed with softened city water for a proper ratio. Due to the alloys in the brass, the company was limited to the types of coolant that would best suit their needs. The plant-based coolant provided an increase in tool life, resulting in significant savings, but it also posed several problems for the machines.

"Non-detect" treatment goal met and 21 million gallons of water cleaned in downtown site

Water One Services combine remote monitoring and responsive service to meet water quality and provide required data management

A leader in advanced wound care, consumer wellness and medical devices was having problems with bacteria control in their water system. As a global expert in dealing with the complexities of wound management, the customer provides innovative solutions for advanced wound dressings and topical skin care solutions.

Spoetzl Brewery’s white brick Alamo-style plant in Shiner, Texas, USA, produces many year-round and seasonal brews—including Spoetzl’s flagship beer, Shiner Bock. The brewery needed a reliable treatment solution that would effectively handle brewery wastewater so that it complied with pretreatment effluent regulations.
