Membranes are used in wastewater treatment for a number of purposes including meeting stringent discharge water quality standards, tertiary filtratration for non-potable reuse and nutrient removal and for potable reuse applications. Drivers for membrane use and the membrane technologies used to treat water for these applications will be covered in ...

The Guidelines for Water Reuse published by the USEPA have served as an authoritative nationalwide reference in the support of state specific regulations. The document covers both non-potable and potable reuse, and was supplemented in 2017 with a Potable Reuse Compendium, focusing on key issues with the implementation of potable reuse. This present...

Pharmaceuticals and other contaminants of emerging concern (CECs) are introduced to the environment from a variety of sources; effluents from centralized wastewater treatment plants (WWTPs) represent the primary source for loading to aquatic systems. Introduction of CECs to aquatic systems can contaminate surface and ground waters and thus present ...

This presentation will provide the attendees with a fundamental understanding of the MBR process technology. Various system confiurations, materials of construction, and basic application priciples. Discussion of the basic subsystems of a MBR will be included as well....

This presentation discusses the causes and solutions for fouling problems with MBR processes. We will review the impact of the biological treatment, influent loads, influent constituents, and ancillary systems have on the MBR process. We will further discuss and present a troubleshooting framework on identifying the source of fouling and how to re...

A food processing facility that makes prepared meats upgraded their wastewater treatment system to MBR because of its capabilities to handle the facilities new requirements. A MBR system satisfied their requirements for increased treatment with variable flow with a small available footprint. A ceramic membrane was selected to provide stable perfo...

The participants will be taken through the City of Coeur d Alene Tickling Filter / Solids Contact advanced Waste Water treatment plant, With ultra-Filtration of our Secondary Effluent with Suez 500D Zeeweed membrane....

Inland Empire Paper Company (IEP) is a pulp and paper mill that produces newsprint and specialty paper products in Millwood, Washington. Over the last 17 years, IEP has been optimizing its process water use and wastewater treatment system in anticipation of compliance with very low nutrient discharge limitations for discharge to the Spokane River. ...

How the City of Coeur d Alene got to wher it is now using Ultra Filtration to Remove Phosphours to very low amounts.How the City of Coeur d Alene got to wher it is now using Ultra Filtration to Remove Phosphours to very low amounts....

Storm driven wastewater flows create a very unique wastewater treatment challenge as the generate extremely rates of flow in a short period of time. Whether it be inflow & infiltration (IandI) or combined sewer, rain events have always been a challenge for all types of wastewater treatment plants. A plant's ability to treat storm flows has always...

The City of West Richland, WA recenlty constructed an industrial wastewater treatment facility specifically for the treatment of winery wastewater. The treatment system includes membrane bioreactor technology so that the water may be reused in the future for landscape/crop irrigation. This presentation will discuss the aspects of the project from...

Ceramic membranes have been around for quite some time, but the technology has often been cost prohibitive for many applications and markets. In the case of sludge thickening, the higher cost per square foot of membrane for ceramic is often offset by the potential gains in achieving sustainable operation at higher percent solids. Ceramic membrane...

The City of Spokane, Washington is implementing tertiary membrane filtration at their Riverside Park Water Reclamation Facility, with the primary objective of producing effluent with a seasonal average total phosphorus concentration of less than 18 parts per billion. The system will have a maximum month average daily flow capacity of 50 million ga...
