Ratings and reviews

Great effort and compilation of most treatment fundamentals and calculations for the water treatment professionals.. It makes it possible to get quick results at your fingertips. However, it should be paired with proper engineering tool for thorough estimation before you can rely of this app... RIGHT? How far these methods are accurate? Forgive me Daniel for asking.. Today is my first day after downloading

Excellent, useful app. I highly recommend it for any water/wastewater professional

Easy to use, fundamental, informative.
