DRINKING WATER FILTRATION CASE STUDIES AND WHITE PAPERS
The groundwater that a southern Louisiana water utility supplies to local residents has traditionally carried a high amount of organic material and color. In the past, the organics were oxidized and broken down by chlorination, but this practice had gone out of favor due to production of disinfection by-products (DBPs) such as Trihalomethanes (THMs) and Haloacidic Acids (HAAs).
Remote Diagnostics Will Reduce Service Costs And Increase Uptime Of Filtration Systems
Filtration OEMs can use built-in device diagnostics to monitor and maintain automation component performance.
Automation Solutions For Fixed-Bed Filters
Handwheel or automated process valve? The worldwide trend is clearly moving towards automation, because it reduces energy and water consumption, especially rinsing water, and increases plant availability. Pneumatic automation of a fixed-bed filter is a good example of this.
AltaPac™ AP-II Ultrafiltration Membrane Case Study
Cibola is a small community located in Southern Arizona along the Colorado River. With a growing population, the community decided to install a centralized water system to replace individual wells.
Antiscalant Impacts Water Reclamation Efforts
Water reuse efforts in the West Coast are a priority and have the Ground Water Replenishing System (GWRS) of the Orange County Water District (OCWD) utilizing new technologies for water conservation.
Water Utility Turns To State-Of-The-Art UV Technology To Help Address Drought
The 2013 year was the driest in recorded history with many areas of the San Joaquin Valley reporting groundwater levels more than 100 feet below previous historical lows.
Water Supply Needs At Odds With Regional Demands To Lower Power Use
The shoreline of the Red Sea is a dazzling destination for tourists and locals to experience the beach and enjoy marine activities. In Egypt, the shoreline sprawls from the Suez Canal in the north, down to the southern part of the country bordering Sudan.
Overcoming Difficult Conditions, Salty Groundwater And Changes In Feedwater Quality
Kibbutz Reim had to convert salty groundwater into a high quality irrigation resource in this desert-like region. High recovery was essential to this customer, both because of the limited amount of groundwater available and the challenge of brine disposal from their inland location.
High Recovery Reverse Osmosis Water Treatment For Industrial, Agricultural, And Municipal Applications
Industry accounts for nearly 60 percent of fresh water withdrawals in the developed world and agriculture consumes 70 percent of fresh water supplies globally, according to UNESCO.
Pulp And Paper Manufacturer Significantly Increases Production While Complying With Discharge Limitations
A U.S.-based pulp and paper manufacturer required high purity process and boiler feed water. It was using water from a local well and treating it with a 150 gpm conventional RO system operating at 75% recovery, but this was creating 50 gpm of wastewater – over 26 million gallons per year.
This leading rod and wire mill requires water for cooling steel and tools in its manufacturing process. Water used for cooling becomes contaminated with metals and lubricants and was therefore being disposed of as waste.

ABOUT DRINKING WATER FILTRATION
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.
