Potable Water professionals are seeking innovative approaches to address water supply challenges associated with population growth, drought, and environmental protection.
Ultrafiltration (UF) membranes have already gained worldwide acceptance in the treatment of drinking water for their removal of chlorine resistant pathogens such as cryptosporidium.
This presentation will discuss the operation of a 4 MGD pressurized two-stage Ultrafiltration (UF) plant over a 14 month period at the Oliver-Mercer-North Dunn (OMND) Drinking Water Treatment Facility, North Dakota.
A Montana Water District was under an Administrative Order of Compliance by the EPA to install filtration to comply with the Surface Water Treatment Rule (LT2ESWTR) or possibly loose their only water source, the Missouri River.
The city of Virovitica in Croatia is located near to the Hungarian border. Its water works company Virkom serves approximately 20.000 people daily with drinking water. In order to assure required European potable water standards, Virkom decided in 2008 to replace the existing old sand filtration units (total flow rate approx. 320 m³/h) by new ones.
The Rueter-Hess Water Purification Facility, located in Parker, CO, southeast of Denver, serves a community of approximately 50,000 residents. Faced with rapidly declining groundwater sources, the 10-MGD facility (expandable to 40-MGD) was opened in 2015 to process a renewable water supply for the Parker Water and Sanitation District (PWSD).
Harmsco® Filtration Products is pleased to offer a solution to the ever increasing blue-algae blooms in water sources. A multi-barrier approach is necessary to physically remove intact (algae and cyanobacteria) before they rupture in the treatment process and then remove extracellular cyanobacteria through adsorption.
Containerized water treatment solutions eliminate many challenges associated with developing a large-scale wastewater or desalination facility.
When the government of Baja California, Mexico, declared a water emergency for the region of San Quintín in 2014, leaders knew they needed to find a solution to ensure residents a reliable, safe water source.
The city of Fort Lupton a growing Front Range community located along the South Platte River in Colorado, began operation of a new 5 MGD (18.93 MLD) membrane filtration system in 1997.
The City of Wilmington, Delaware is situated where the Christina River and the Brandywine Creek flow into the Delaware River.

Water treatment filtration involves the removal of suspended particles from water by passing the water through a filtration medium. As the water passes through the filter, floc, minerals, microorganisms and other impurities get stuck in the filter and are removed from the filtered water. Passage can be blocked by physical obstruction, biological action, adsorption, absorption or a combination of ways. Filtration is usually the final step in the solids removal process during water treatment which typically begins with coagulation and advances through flocculation and sedimentation.
Unfiltered or turbid water is difficult to disinfect because microorganisms growing on suspended particles are often harder to kill than when they are separated from the particles. Turbidity can also cause unwanted taste and odor issues in the potable water supply. Drinking water filtration is also used to remove microorganisms that are resistant to traditional methods of disinfection such as chlorination. By requiring a low turbidity in finished water, water treatment plants are ensuring that few or no microorganisms such as Giardia are present in finished drinking water.
There are three typical methods of clean water filtration used during the water treatment process. Conventional filtration follows coagulation, flocculation and sedimentation and precedes disinfection. Direct Filtration follows coagulation and flocculation when there is no sedimentation step. The final method called In-Line Filtration takes place without flocculation or sedimentation. A coagulant chemical is added to the water just before filtration and coagulation occurs in the filter.
There are many types of filter media being used in today’s water treatment industry.
