  • Ultrafiltration and Reverse Osmosis for Landfill Leachate Treatment

    Lanchester Landfill serves Eastern Lancaster County and Western Chester County in PA for disposal of household and construction waste. The facility produces around 10,000 gals per day of leachate. The Problem The facility ran a single basin sequential batch reactor (SBR) and a filter press to dewater the solids for many years, but found that they first, could not sustain a ...

  • How NoMonia Works to Treat or Remove Your Ammonia - Case study

    Most water utilities should have effective treatment methods for the filtration of arsenic, iron and manganese from drinking water sources. However, as ammonia becomes increasingly concentrated in groundwater throughout the U.S., many utilities around the country are searching for ways to successfully treat the contaminant, while also meeting U.S. Environmental ...

  • Application of the membrane technology to control ammonia in surface water

    Amnonium ion is effectively removed by Reverse Osmosis membranes (Brackish water, BW; Saline water, SW). The removal efficiency of ammonium ion from a solution containing ammonium ion which is not complexed is varying in the range of 5–60%. On the contrary, ammonium ion forms complexes with other ions in water and wastewater removal efficiency was as high as 99% for the synthetic solution which ...

  • A pilot study of a subsurface-flow constructed wetland treating membrane concentrate produced from reclaimed water

    A pilot study was conducted for 7 months for the City of Oxnard, California, on the use of constructed wetlands to treat concentrate produced by microfiltration and reverse osmosis (RO) of reclaimed wastewater. The treatment performance of a transportable subsurface-flow wetland was investigated by monitoring various forms of nitrogen, orthophosphate, oxygen demand, organic carbon, and selenium. ...

  • Household survey of installation and treatment efficiency of point-of-use water treatment systems in Hanoi, Vietnam

    Since urban water supply is not yet available for every inhabitant in Hanoi City, numerous residents look for alternative sources such as groundwater and rainwater to compensate the supply shortage. However, in parts of Hanoi, it was reported that groundwater is polluted by various contaminants including arsenic (As) and ammonia (NH4-N). Therefore, numerous types of point-of-use (POU) water ...

  • Evaluation of Potential Benficial Reuse of San Ardo Produced Water

    ABSTRACTThe goal of this DOE, Aera Energy LLC, and Kennedy/Jenks Consultants funded project was to evaluate the potential for treatment and beneficial reuse of produced water from an oilfield in San Ardo, California. A 10 - 30 gpm reverse osmosis (RO) pilot plant was constructed and operated for nine months. The key constituents of concern include total dissolved solids (7000 mg/l ...

  • Decoding the AdEdge treatment matrix

    U.S. drinking water utilities come up against a variety of water quality issues. From aesthetic issues to naturally occurring contaminants and contaminants resulting from industry processing, no water source is without problems. Contrarily, many of them have co-occurring contaminants, which complicates the treatment process. Although there is no single treatment solution that will successfully ...

  • Chloramines

    OVERVIEW When chlorine is added to a water supply containing certain organics, the formation of halogenated organics occurs. Called 'trihalogenated methanes' (THM's) these reaction products are suspected carcinogens and maximum allowable limits in municipal supplies are imposed by the U.S. Environmental Protection Agency (EPA). To reduce the potential for the formation of THM's, many U.S. ...

  • MABR: Familiar WWTP Principles, Better Results

    Wastewater treatment plant (WWTP) designers and decision-makers tasked with finding more cost-effective performance for challenging applications want new options. Here is how flat-sheet membrane aerated biofilm reactor (MABR) technology tweaks the chemical and biological functions of conventional activated sludge (CAS) processes to reduce energy consumption and operating expenses (OPEX) in ...

  • Different Biological Water Filtration Systems

    Do you know what’s in your water? Most people don’t. It’s recommended that you drink at least a half-gallon of water each day. If it’s not purified or filtered, that water could be causing unseen damage to your body. Arsenic, salmonella, streptococcus, and influenza viruses could all be present in your tap water. There are many different forms of biological filtration that ...

  • Innovative Approaches to RO Concentrate Management: Beneficial Reuse and Concentrate Minimization

    ABSTRACTDesalination of brackish waters and reclaimed waters using reverse osmosis (RO) is often limited by the options available for concentrate disposal, particularly in inland areas. Dewatering the concentrate is alternative approach to disposal but the available thermal and membrane technologies are still cost prohibitive for most applications. Beneficial reuse of the RO concentrate ...

  • Closed loop system takes manure and methane

    A CONVERSION plant in Mead, Nebraska is processing manure and methane to create ethanol and compost. According to Nebraska Governor Dave Heineman: “This plant sets a new standard for ethanol production in this state and our nation, and is an example of the innovation needed to take this industry to the next level. It lets America get its automotive fuel from the croplands of the Midwest instead ...

  • Electrocoagulation Wastewater Treatment: Specialized Technology to meet the needs of food & beverage wastewater

    The effects of water scarcity and stricter environmental regulations placed on water usage are increasing the cost of using freshwater globally. The consequences of these increasing costs on food and beverage companies are twofold, since the companies are charged for both the water that they utilize in their processes and on their wastewater discharge. Additionally, the food and beverage industry ...
