A Southern California refinery resolved stormwater discharge permit violations in five days using Xylem’s vessel-based treatment system with organoclay, carbon, and ion exchange to remove hydrocarbons and metals to ppb levels.

Bowling Green Municipal Utilities (BGMU) provides commercial water and wastewater treatment and electrical power services to a population of more than 60,000 in the community of Bowling Green, KY.  In 2010, the BGMU wastewater treatment plant was approaching the end of its useful life, just as the utility’s operating permit was up for renewal.

A Minnesota mine reduced copper and cobalt in its discharge using wastewater ion exchange, achieving compliance without chemicals and adapting to seasonal flow increases.

After installing Xylem's Wedeco MiPro eco3 advanced oxidation process system K-Water was able to eliminate taste and odor complaints economically.

Before deciding on the 4320s, Kennedy Industries along with YCUA operations and maintenance personnel performed an extensive energy study of the aeration mixers.

Shanghai Xinlun Paper was upgrading its pulping and paper-making process. As this was taking place, new regulations came into effect that required the mill to invest in secondary wastewater treatment so it could meet stringent effluent limits of 100 mg/l chemical oxygen demand (COD), 30 mg/l biochemical oxygen demand (BOD), and 200 mg/l total suspended solids (TSS).

BALTEN needed to modernize its outdated infrastructure and software platforms, so it could optimize its irrigation water transportation system and improve the overall performance of its irrigation water service.

Bell & Gossett manufacturer’s representative, Hydro-Flo, in Brookfield, Wisconsin, presented a solution to the VA’s pump room challenge: the VSX vertical split case pump.
