In 2009, the city of San Benito, TX completed the construction of a new six-million-gallon-per-day (MGD) microfiltration plant, which replaced a plant that had been in operation since 1928. The new facility is considered one of the most modern and innovative water treatment plants in the region and has been recognized for its use of microfiltration and solar power. Its chlorination system, while more traditional than these technologies, was selected for its cost-efficiency, reliability and flexibility.

0 Comments

With longer laterals being drilled and stages being added, well completion by hydraulic fracturing (frac) now requires an ever-increasing amount of water for every well that is drilled and completed. Ensuring that the water used in frac is free of bacteria is a critical part of the overall treatment and conditioning of water before it is sent downhole. This is especially true as more operators are using recycled flowback and produced water for completion activities.
