United Water, a division of the global conglomerate Suez Environement, operates regulated water systems in eight states, and provides contract services to over five million people.
Responsibility for analysis results lies with the users themselves or their supervisors. Both are therefore liable for any incorrect interpretations and decisions that are made as a consequence of incorrect data.
Desalination Technology Transforms 650 m3/day of Abused Industrial Wastewater
There are a number of advanced water treatment tools available today that were not available 10 years ago, which broaden the approach to finding the most effective and least expensive treatment alternatives. Pilot testing of various technologies is the most beneficial method to determine the efficiency of treatments.
Santa Margarita Water District (SMWD), located in southern California’s Orange County, between Los Angeles and San Diego, provides drinking water and wastewater services to over 165,000 residents and businesses. SMWD approached UGSI Solutions about a Polyblend® Polymer Activation System trial at their 3 A Water Reclamation Plant.
Iron, manganese, arsenic and hydrogen sulfide are indigenous to numerous groundwater aquifers. With the exception of arsenic, these constituents are more prevalent in deeper aquifers that are devoid of dissolved oxygen. This report summarizes the results and conclusions of a groundwater treatment pilot test program. This pilot test program was undertaken to determine the removal performance for arsenic, manganese and iron at the City of Merced’s Well 20 site. Chemical treatment processes required were also studied.
Sabine Pass, a large LNG refinery in the U.S., required a membrane desalination solution to cater to its extensive process water needs in order to produce a large amount of liquefied natural gas for export.
Bluebonnet Rural Water Corporation (BRWC), a subsidiary of Bluebonnet Electric Cooperative, serves approximately 1,094 water meters in northeast Washington County, TX, but had a water storage problem not unfamiliar to even the largest water utilities in Texas.
Energy consumption from aeration system is a biggest part of the total energy cost in wastewater treatment plant and account for as much as 60% of the energy consumption for the activated sludge process. Therefore, it is very important to know how effective the aeration system and significant attention has been paid to development and upgrade of standard method for quantifying oxygen transfer efficiency of the aeration system.

While point level measuring approaches are regarded as simple and user friendly, they lack the capabilities of more sophisticated continuous measuring instruments.
