Packaged Membrane Filtration System Provides Optimum Solution For Historic Resort

Following a comprehensive evaluation, the water company’s consulting engineer recommended the Memcor® XS submerged packaged membrane filtration system. The pre-engineered, skidded membrane system is pre-wired, pre-piped and factory tested before shipment.

Packaged Membrane System Helps Town of Oak Creek, CO Meet Drinking Water Needs

Anticipating the spring run-off season and the need to treat a wide range of raw water quality, the Town of Oak Creek developed a fast track, design-build schedule to find a solution to its water treatment needs.

Perchlorate Removed from Groundwater for West Coast Aerospace Manufacturer

Aerospace manufacturer repairs liquid fueled rocket engines and solid rocket motors for the Department of Defense and NASA. During the rebuilding process, older fuel was removed and disposed using approved methods. Unfortunately some of the material found its way into the groundwater and there are perchlorate levels in the parts per million range.

Private Placement Financing Tailored for Princeton, Minnesota

The Public Utilities Commission(PUC) of the City of Princeton, Minnesota used private placement financing to build a new water treatment facility for the municipality to accommodate its growing population. Construction of the new facility began in 2005 and was financed by a Revenue Bond. As construction progressed, material and construction costs were greater than originally budgeted, resulting in cost overruns over $2 million. Trying to refinance the existing bonds to a new public issue for a greater amount would impose yet another delay to completing the project. Not only did Princeton PUC need to get these overrun costs and Siemens Water Technologies equipment financed in a quick manner, they also wanted to refinance the revenue bonds.

Procuring a Water Treatment Solution Using an Uncommon Method

In 2001, the Slinger Village Board wanted to provide their citizens with better drinking water by installing an iron removal plant to remove the 1.6 parts per million (ppm) of iron in its well water supply. They had been using a sequestering agent to control the iron, but felt that removal was a better solution, as it would reduce the frequency of flushing the mains and provide rust-free water to residents.

Reject Recovery Reverse Osmosis Technology Selected to Reduce Water Usage

When a U.S. Bottler needed to reduce water usage, they chose a system that included reject recovery reverse osmosis (RO) technology.

Rocky Mountain Drinking Water Plant Removes Manganese and Improves Turbidity with Chlorine Dioxide

The plant has a problem with manganese: levels rise in the fall as the water temperatures in the reservoir drop until the turnover of the reservoir in summer. Implementation of a new pH adjustment system in 1992 increased the pH of the water leaving the plant, causing some of the soluble manganese to oxidize and precipitate out in the storage tanks and pipelines. Numerous ‘brown water’ complaints from city residents followed. Potassium permanganate was employed at dosages from 0.2 - 1.2 mg/L during 1993 and early 1994 but failed to adequately control the problem and the city still received complaints. The city began looking for an alternative treatment approach in 1994.

Sierra Conservation Center Seeks Additional Treatment Capacity

The Sierra Conservation Center required extra filtration capacity during their rainy season and while reconditioning and repairs of their potable water treatment plant was completed. Heavy rains increased turbidity of the surface water to 80 NTU creating water not suitable for potable drinking water.

Southeastern Municipality Uses Chlorine Dioxide to Control THMs in Drinking Water

This plant produced relatively high levels of THMs in the drinking water. An alternative primary disinfectant was required, which would prevent the formation of elevated levels of THMs while adequately disinfecting the drinking water.

Submersible Chemical Inductor Brings Better Floc, More Consistent Finished Water Quality

A Water Treatment Plant located in Sheboygan, Wis. installed a submersible 3-h.p Water Champ Chemical Induction Unit. The Water Champ CIU provided the 35 million gallons (MGD) facility with better floc and more consistent water quality.
