Join our free webinar on September 16th from 2:00-2:45 p.m. EDT  

Register now to join Dr. Robert Smith for an informative webinar addressing the treatment options available and process monitoring solutions to achieve the required performance at the lowest operating cost.

Recent events have demonstrated that excess phosphorus in receiving waters can create many serious problems including impairment of drinking water supplies.   For this reason and others, incorporation of phosphorus limits into NPDES discharge permits is occurring in many states.  

Many facilities are being required to remove phosphorus for the first time and will need to add a process to the flow sheet.  A discharge limit of 1.0 mg/L may be achieved most cost-effectively with chemical addition.  Enhanced biological treatment may be needed to meet lower limits down to 0.5 mg/L and below.  Additionally, biological treatment has other potential benefits.  

Regardless of the treatment method, continuous monitoring is essential.  Critical parameters include orthophosphate, dissolved oxygen, oxidation-reduction potential (ORP), total suspended solids, and nitrate.  

Dr. Rob Smith is Applications Engineer – Wastewater at YSI.  He has nearly 20 years of experience as a wastewater treatment specialist.  His job responsibility at YSI is to assure customers obtain high quality, useful data from their YSI instruments.

The live webinar will be recorded and you will receive a link afterwards to view the recording.
