  • 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 ...

  • How to Treat Water and Remove Arsenic

    Arsenic is a naturally occurring element from the earth’s crust. Around the world, many countries have groundwater that is steeped in arsenic. Until recently, governments haven’t realized just how bad arsenic was for people, even in minute concentrations. In 2001, the US Environmental Protection Agency felt it necessary to lower the drinking water arsenic standard from 50 parts ...

  • 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 ...

  • Monitoring the effectiveness of advanced sorption materials for removing selected metals from water

    There are a number of ways to remove heavy metals from water. Sorption on granular media based on iron oxides and hydroxides is currently the most used option. The experiment was carried out using sorption materials GEH, CFH 0818, CFH 12 and Bayoxide, which are primarily designed to remove arsenic from water. Four columns were prepared with an inner diameter of 4.4 cm for the purpose of the ...

  • Flood recovery project - Case Study

    Greener Waste Technology has been working with a utility company to combat the effects of flooding on a filter bed works. The works in question is low lying and next to a river which recently burst its embankment and flooded the filter beds entirely. The flood distributed large volumes of silt and mud onto the filters blocking the beds and starving the indigenous bacteria population of oxygen ...

  • Biomass granulation in an upflow anaerobic sludge blanket reactor treating 500 m3/day low-strength sewage and post treatment in high-rate algal pond

    A pilot-scale upflow anaerobic sludge blanket-moving bed biofilm (UASB-MBB) reactor followed by a high-rate algal pond (HRAP) was designed and operated to remove organic matter, nutrients and pathogens from sewage and to facilitate reuse. For an influent chemical oxygen demand (COD) concentration of 233 ± 20 mg/L, final effluent COD was 50 ± 6 mg/L. Successful biomass granulation was observed ...

  • 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, ...

  • Fixed vs. Moving Bed Systems: Basin Geometry

    Aeration basins can have length to width (L:W) ratios varying from 1:1 (square) to over 30:1 (plug flow). The L:W ratio of an aeration basin directly impacts both the physical installation and biological performance of a submerged fixed-film system. Physical Installation Moving bed biomass carriers are free to move about the aeration basin. The aeration system provides energy to ...

  • Microfiltration vs Ultrafiltration Processes: What is the Difference?

    Microfiltration (MF) and ultrafiltration (UF) are both processes by which a contaminated liquid is passed through a semipermeable membrane that removes solids too large to fit through the membrane’s pore size, yielding a purified liquid stream. To what degree the stream is purified depends on the contaminants present and the pore size of the membrane. MF and UF are generally ...
