A More Efficient Approach To EPA Stage 2 DBP Compliance
A More Efficient Approach To EPA Stage 2 DBP Compliance

Everyone wants pathogen-free drinking water, and adding chlorine is a great way to get it. Unfortunately, the dirtier a water treatment plant (WTP)’s raw water inflow — in terms of natural organic matter (NOM) or microbial organisms — the more disinfection byproducts (DBPs) the chlorination process will generate in the form of trihalomethanes (THMs) and haloacetic acids (HAAs). Those DBPs increase the risk of non-compliance with the U.S. EPA’s Disinfectants and Disinfection Byproducts Rules. Choosing the right instrumentation to measure NOM through spectral absorption coefficients (SACs) can have a big impact on treatment strategies — in terms of both costs and compliance performance.

  • Air / Gas Mass Flow Meter Improves Wastewater Treatment Processing Efficiency
    Air / Gas Mass Flow Meter Improves Wastewater Treatment Processing Efficiency

    One of the most common processes in wastewater treatment is the activated sludge method, which biologically treats the wastewater through the use of large aeration basins. This process requires the pumping of compressed air into the aeration basins where a diffuser system ensures the air is distributed evenly for optimum treatment. The energy needed to provide compressed air is a significant cost in the operation of a wastewater treatment plant.
