3/28/2017Biofilter Conversion Guidance Manual
Biofiltration may address a wide range of drinking water treatment objectives, such as filtration, contaminant removal (e.g., manganese, ammonia, taste and odor, disinfection by-product precursors), improved disinfection, and distribution system stability. As a result, many utilities are interested in converting their existing conventional filters to biofilters.  Previous studies have shown that upstream treatment processes and other process parameters (e.g., filter media, empty bed contact time (EBCT), oxidant dose, filter influent nutrient levels, etc.) can affect biofilter performance. Furthermore, some process upsets may occur immediately after filter conversion, which can result in short-term water quality and hydraulic challenges.  

​The Biofilter Conversion Guidance Manual (#4496) was designed to help utilities better understand the factors impacting the success of biofilter conversion planning and implementation, challenges faced during filter conversion, and potential mitigation strategies.  This webcast will present data and information collected during the study and included in the Biofilter Conversion Guidance Manual and Excel-based Conversion Assessment Tool.  Specifically, the webcast will cover:
  • Conclusions from case studies highlighting the effects of media type, media age, and operating conditions on biofilter conversion
  • Results from the conversion survey including data from 16 full-scale facilities that converted to biofiltration and  have been practicing biofiltration for 2 to 10+ years
  • A preview of the Conversion Assessment Tool, which allows utilities to estimate the relative suitability of specific facilities for conversion to biofiltration
  • A preview of the Biofilter Conversion Guidance Manual.​
4/13/2017Recent Findings on Developing Public Health Guidance for Decentralized Non-Potable Water Systems
Hosted by WateReuse, this webcast will discuss the recently released report, Risk-Based Framework for the Development of Public Health Guidance for Decentralized Non-Potable Water Systems (WRF Project #4632, WE&RF Project No. SIWM10C15). The report culminates a year-long research effort led by the National Water Research Institute (NWRI) and an Expert Panel – with input from a Stakeholder Group of public health agencies and water/wastewater utilities – to address a primary institutional barrier to onsite water treatment: developing scale-appropriate water quality criteria and monitoring.

The session will begin with a brief overview of workshops and efforts such as the Blueprint to Onsite Water Treatment that led to this research effort. Speakers from the Expert Panel will then provide an overview of the report, main findings, and key examples of onsite treatment trains and responsible system monitoring efforts. Finally, participants will hear about current efforts of the National Blue Ribbon Commission for Onsite Non-Potable Water Systems and putting the results of this ground-breaking research into practice.
