Optimizing Chemical Dosing Reduces Chemical Use While Meeting Effluent TP Limits | By Sanitaire -- A Xylem Brand | The city of Black River Falls in Wisconsin used chemical treatment with ferric chloride (FeCl3) to achieve its effluent total phosphorus (TP) permit of 1.0 mg/l. Historically, the chemical dosing rate was manually adjusted on a daily basis based on the measured effluent TP concentration. The plant was upgraded with an OSCAR process performance optimizer control system with phosphorus controller, which uses continuous measurement of orthophosphate.

Finding Your Next Chemical Metering Pump | By Cleanwater1 | There are plenty of bells and whistles at a given water treatment plant. Between pumps, mixers, dry chemical feeders, and other chemical handling equipment, it can be easy to go with the status quo when it comes time to upgrade certain pieces of equipment. For an operation’s chemical metering pumps, this usually meant replacing one unit with its exact replica, instead of facing the often-arduous task of researching a better option. |

CDOX And CO2-Based System Replaces Manual Chemical Dosing Of Strong-Acids, Increasing Workplace Safety | By ChartWater BlueInGreen | The wastewater pretreatment plant processes effluent from the manufacturing facility prior to discharging into the sanitary sewer system for treatment at the municipal wastewater facility. Use of sulphuric acid to manage the pH of the wastewater in the buffering reactor tank prior to entering the DAF for solids and oil removal was considered to be an unnecessary risk requiring significant safety protocols. |
