  • How Arsenic Biological Filtration Systems Can Improve Your Life

    Water is the foundation of human existence. It’s used for cooking, bathing, cleaning, and most importantly, drinking. Unfortunately, water is often dirty and contaminated, especially when it’s pulled from groundwater sources and wells. Since many cities have been shown to have low-grade drinking water, concern has increased about water quality. Many people are wondering if their water ...

  • Organic matter capture by a high-rate inoculum-chemostat and MBBR system

    The main objective of this study was to develop an innovative process to maximize the bio-transformation of colloidal and soluble biodegradable matter (CSB) into particulate matter (XB) for energy recovery via methane production. Two configurations were studied: (1) high-rate moving bed bioreactor (HR-MBBR) and (2) inoculum-chemostat (IC) system consisting of a very HR-MBBR inoculating a ...

  • 4 Types of Contaminants in Water

    The EPA says that there are 4 type of water contaminants: physical, chemical, radiological, and biological. Its definition includes anything that is not an actual water molecule. That means that naturally occurring things like sediment and water weeds are considered contaminants along with things like oil and uranium. Chances are good that the type of contaminants your company needs to keep out ...

  • Making your drinking water safe with biological water treatment

    As society becomes more environmentally conscious, it is important that your community is provided with its natural necessities in an eco-friendly manner. One of these natural necessities includes adequate drinking water. Many companies use chemical treatment methods to help cleanse and purify water resources, but such methods are often at the expense of your local environment. Some water ...

  • Find the right wastewater solution for your leisure centre, factory or office civils project

    Designing an off-mains drainage solution for a commercial facility such as a leisure centre, factory, or an office, should never be considered a simple job. It requires qualified and expert guidance to ensure compliance with the stringent legal requirements which must be observed.

  • Effect of SBR feeding strategy and feed composition on the stability of aerobic granular sludge in the treatment of a simulated textile wastewater

    Treatment of the highly polluting and variable textile industry wastewater using aerobic granular sludge (AGS) sequencing batch reactors (SBRs) has been recently suggested. Aiming to develop this technology application, two feeding strategies were compared regarding the capacity of anaerobic–aerobic SBRs to deal with disturbances in the composition of the simulated textile wastewater feed. ...

  • Solutions for Safe Drinking Water Through Biological Water Treatments

    Most people across the U.S. expect to turn on their faucets and have immediate access to clean drinking water. The truth is, it wasn’t until 1974 that Congress passed the Safe Water Drinking Act with the goal of regulating the nation’s public water supply. Over the years, the SWDA has been amended to include water sources as well, such as rivers, lakes, springs and groundwater wells ...

  • 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. ...

  • The Best Ground Water Treatment Methods

    Many homes and businesses depend on ground water or surface water as a vital water source. Unfortunately, much of this water has not been filtered through municipal water treatment and distribution technology. This means that the water many people consume, cook with, and use for basic hygiene can contain potentially harmful particles, including pathogens, tiny organic matter, sediment, ...

  • Effect of cycle run time of backwash and relaxation on membrane fouling removal in submerged membrane bioreactor treating sewage at higher flux
