  • Types of Water Treatment Systems

    There are different types of water treatment systems, and knowing the difference between them can help you make an informed decision on just what type of treatment you’ll need for your water. There is no best water treatment system that will meet everyone’s needs—each system has its benefits and deficiencies. Here are a few ...

  • Biological Filtration: Future of Drinking Water Treatment

    Water is essential for all human life on the planet, but the fresh water supply is limited and is susceptible to being contaminated by all manner of toxins like arsenic, calcium, and mercury. There are many techniques to remove contaminants, including popular methods that add chemicals to balance others out, but one that not many people understand is biological water system filtration. ...

  • Effects of recycling flocculation membrane filtration on drinking water treatment

    Recycling flocculation membrane filtration (RF-MF) and coagulation membrane filtration (C-MF) were investigated for removal of natural organic matter (NOM) from Luan river in this study. The effectiveness of recycling flocculation pretreatment on both NOM removal and membrane filtration were assessed under different concentrations of coagulant and reflux flocs. Under the conditions of coagulant ...

  • Use of anthropogenic gadolinium as a tracer for bank filtrate in drinking water wells

    Knowledge of the amount of bank filtrate in raw water is crucial for drinking water suppliers using water wells in close proximity to rivers, in particular if those rivers are strongly affected by anthropogenic activities, e.g. receiving effluents from waste water treatment plants. Analysis of organic micropollutants as tracer compounds is costly and time-consuming, and results may be biased by ...

  • The Future of Drinking Water

    Predicted future growth in population numbers and rising sea levels mean demand for drinking water will continue to increase just as the natural availability of freshwater decreases. It is likely that brackish groundwater will be an important source of drinking water in the future, but the current methods used to produce fresh water from this source are expensive in terms of their energy use and ...

  • Use of horizontal flow roughing filtration in drinking water treatment

    In order to evaluate the feasibility of implementation of horizontal-flow roughing filtration for drinking water treatment a pilot was designed and run at the bank of Zayandehroud river near the village of Chamkhalifeh. Pilot running was performed in summer 2003 (July, August and September), when the quality of river water was in relatively worst condition. The filter is comprised from three ...

  • Using Biological Filtration to Remove Arsenic from Drinking Water

    In 2001, the U.S. Environmental Protection Agency changed the standards for arsenic levels in drinking water. At that time, the agency had estimated that more than 36 million Americans were drinking water that contained arsenic levels at or above 3 parts per billion. A new standard was set, lowering the maximum contaminant level to 10 parts per billion (ppb) from the previous standard of 50 ppb. ...

  • Nan H2O filtration Drinking Water Production – Membrane Filtration Municipality of Lac - Bouchette

    Located in Lac-Saint-Jean, Quebec, Lac-Bouchette is a municipality of 1,400 inhabitants. For its supply in drinking water, the Roche Ltd Consulting Group recommended the municipality to call on H2O Innovation’s services. This, following a pilot study executed on the water of the Ouiatchouan lake that has been carried out from May till October 2003. The nanofiltration treatment system called ...

  • The Benefits of Biological Treatment for Drinking Water

    The biological treatment of drinking water is undertaken using both organic and inorganic contaminants, and can be used to treat groundwater and surface water. These contaminants, contrary to what the name implies, are applied to strip away the factors that make the water unsafe for drinking until it is potable—meaning drinkable. If you would like to learn more about the benefits of ...

  • Why is drinking water treatment necessary?

    Water is found in ample amount almost everywhere on earth. The natural water resources such as lakes, rivers, etc. that provide water contain a lot of pollution, garbage which is unfit for human consumption. To clean the water, it should undergo numerous water treatment media procedures that make it suitable to drink. The water ...

  • 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 ...

  • Micronized CaCO3: a feasible alternative to limestone filtration for conditioning and (re)mineralization of drinking water?

    Worldwide limestone filtration is used in many treatment plants for the conditioning and (re)mineralization of drinking water to increase concentrations of Ca2+ and HCO3−, pH and saturation index, thereby improving the quality of the water regarding corrosion control, buffering and taste. Typical applications include (very) soft groundwater with (very) low alkalinity and desalinated water. In ...

  • A pilot plant study of the processes of filtration and adsorption of drinking water through granular activated carbons: a comparative study

    This study reports a procedure for the evaluation and comparison of the adsorption and filtration capacities of commercial activated carbons in the treatment of drinking water and the design and operation of a pilot plant to simulate the behavior of fast open filters made of granular activated carbon. The milestone of this experimental work was to determine the adsorption and filtration ...

  • “Ozone” and “GAC filtration” synergy for removal of emerging micropollutants in a drinking water treatment plant?

    Ozonation plays an essential role in water disinfection to inactivate viruses, bacteria and some parasites (Giardia). Ozone treatment rates to attain disinfection goals also result in oxidation reactions of emerging pollutants. Pharmaceuticals–except Ciprofloxacin–are very reactive to ozone: they are removed as early as the transfer compartment outlet even at an ozone treatment rate ...

  • City Water International explains The Basics of Water Filtration

    The Basics of Water Filtration Most of us know that filtered water is healthier than tap water because of its purity, but how does water filtration work? The basic principle is that filtered water has passed through a filter which removes contaminants through one of several methods, depending on the type of filter. Most water purification systems work in one of three ways ­ by running water ...

  • Why Everyone Should Drink Filtered Water

    Your body is made up of a lot of water; 60 to 65 percent to be exact. The water that you drink each day helps to replenish your body and give you strength. But, if you’re drinking water that contains heavy amounts of chemicals, metals, and other harmful ingredients, what does that say about your body composition? Untreated water could be responsible for a number of different health and ...

  • Removing Chloramines from Drinking Water Supplies

    Historically, most public water supplies have been treated with chlorine to satisfy the standards set by the Safe Drinking Water Act of 1974. Since being established, there is reason to believe that the standards may be too lenient on the allowable contaminant levels in our drinking water. For instance, chlorine and other disinfectants react with organic matter creating ...
