After decades in service, the wet well at the Laguna Southwest Orange County Wastewater Authority (SOCWA) lift station became dilapidated. The project included a hybrid manhole/junction structure that would also serve as the bypass wet well during the rehabilitation work. Upon completion of the wet well rehabilitation, the temporary sewage bypass pumping system was removed and normal lift station operation was restored.
In late 2013, Headworks Bio Inc. was awarded a contract with General Contractor Soluciones Tecnicas Ambientales, S.A. (SOLAMSA) to supply an IFAS system to upgrade the existing Ptar El Roble conventional activated sludge (CAS) treatment facility in Puntarenas, Costa Rica — the first IFAS installation in the country.
In order to improve the efficiency of biofilm technologies, a high-performance biocarrier has been developed, based on requests for ideal carrier characteristics.
With the AnoxKaldnes Hybas IFAS system, the City of Cocoa Beach, FL, met the challenges of tighter nutrient regulations, site constraints, and operating conditions. And the project met the city’s goals to meet these challenges with a simultaneous decrease in energy use. On top of that, the city did not need to increase operations time or staffing to meet these goals. With the AnoxKaldnes Hybas IFAS system, the city is now meeting stricter nutrient regulations – and doing it sustainably.
The Kittansett Golf Club in Marion, Massachusetts is rated one of America’s 100 Greatest Golf Courses by Golf Digest Magazine.
Turning wastewater into drinking water. Fueling cars with tap water. Installing “waterless” toilets in airport restrooms. Each and every day, people around the globe are trying to transform the water industry in many ways. Here are five steps to help you revolutionize the water industry.
The Bissell Point Wastewater Treatment Plant is the largest wastewater treatment facility in Missouri with an average flow rate of 123 MGD. In the mid-1980s, the facility expanded to provide secondary treatment. The goal of the upgrade was to select a reliable process that would achieve high-rate BOD removal.
The State Water Commission of Jalisco (CEA Jalisco) is responsible for several municipal wastewater treatment plants discharging into Lake Chapala.
The Old Orchard Beach Wastewater Treatment Plant (WWTP) serves the town of Old Orchard Beach, Maine, a coastal resort community where the population swells from 9,000 year-round residents to 75,000 in late June through early August, when seasonal residents and day trippers descend for the peak summer months.
The successful addition of new restaurants and clubs at a resort and casino in Upstate NY brought with them a flow of fats, oil and grease (FOG), which gelled into a floating blanket atop the main station’s wet well, where the sewage flows converge from the network of smaller stations throughout the property boundaries.
The City of Geneva is located on the Seneca Lake in the wine-producing area of New York known as the Finger Lakes region. The drinking water facility, a Pall 2-train custom Aria™ membrane system, is operated by a team that prides itself in serving the clean water needs of its constituents. Integral to those efforts is the leveraging of tablet technology for maximizing plant operating efficiencies and minimizing downtime.
The C445 motor management relay offers the most configurable protection options in the industry, with features specifically designed to protect critical pumps from costly damages due to dead-head and other underloaded or starved pump conditions.
Excess ammonia in receiving waters causes algal blooms that decrease oxygen levels. For this reason, many wastewater treatment plants (WWTPs) must limit ammonia in discharge. Mike Rousey, Hach Company
Homes, industry, schools, and businesses all generate sanitary waste, or sewage. Sewage treatment is a multistage process that cleans up wastewater before discharge or reuse. In the final step of the treatment, disinfectants are added to kill disease-causing organisms. Common disinfectants are chlorine gas and sodium hypochlorite. Chlorine dosage levels are designed to leave almost no residual in the wastewater after treatment
With the increasing awareness about the negative effects of organics within the water and wastewater treatment process along with increasingly strict water quality regulations, the need for more effective organics removal is becoming more important.
Hot Clean-In-Place (CIP) sanitization is commonly used to combat microbial growth in the pharmaceutical and food and beverage industries. Performed frequently as a prevention strategy, hot water sanitization is a requirement for high purity water (HPW) for United States Pharmacopeia (USP) and European Pharmacopoeia (Ph. Eur.).
A static headspace method was developed using Teledyne Tekmar automated headspace vial samplers to meet the method requirements of the Alcohol and Tobacco Tax and Trade Bureau of the US Department of the Treasury (TTB) method SSD: TM:2001 for testing fusel alcohols in alcoholic beverages.
Electrodeionization (EDI) is a widely used water treatment process. EDI technology is an electrochemical process that uses ion selective membranes and an electrical current to continuously remove ions from water. The process uses ion exchange resin to remove the ions from the feed stream, producing pure water.
Monitoring phosphate during the wastewater treatment process allows for fine-tuning and optimizing chemical dosing for removal of phosphate, which provides significant cost savings to the plant while protecting the aquatic environment downstream of the facility.
Phosphorous promotes eutrophication in surface waters and helps create conditions for algal blooming and oxygen depletion. Some phosphorous removal can occur naturally in a conventional biological wastewater treatment facility, but the result is not reliably compliant with increasingly strict limits on permissible phosphate levels in effluent discharged to receiving streams, ponds and lakes. By Bob Dabkowski, Hach Company
Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry.
Most companies and agencies today operate with the concept of business sustainability. This is a holistic way of managing a business that includes environmental, social, and financial responsibilities. To meet this triple bottom line, companies must find ways to be cost-efficient, socially responsible, and eco-friendly at the same time.
Even though 70 percent of our planet is made up of water bodies, yet the world is facing a dire scarcity of water, a basic necessity of life. More than 97 percent of the water resources available are in the form of saline water in the seas and oceans. Water is always at a high risk of getting contaminated/polluted. With rapid urbanization and demographic growth across the globe, the world has seen a staggering rise in the number of industries.
Hydraulic fracturing is a hot-button issue, but no matter where you land you should agree that more efficient produced water filters will go a long way in improving the practice.
Many wastewater utilities are under regulatory mandates to reduce effluent nitrogen and phosphorus. When trying to determine the best method for biological nutrient removal (BNR), lifecycle costs are an important factor.
Rapid industrialization and tightened water quality standards are leading to an increase in global spending on water quality monitoring instrumentation. Spending in this area is projected to grow from $2.5 billion in 2014 to $3.6 billion by 2020, with some 25 percent spent on new, less expensive water quality monitoring sensors that deliver on-the-spot measurements.
San Francisco’s water and wastewater utility has developed a holistic approach to resource management, sustainable infrastructure, and reuse. What can other utilities learn from its program?
