  • High performance turbidity filter

    Turbidity in water is caused by suspended and colloidal matter such as clay, silt, finely divided natural organic matter (NOM), inorganic matter and plankton plus other microscopic organisms, according to Standard Methods 2130. Waterborne pathogens have caused significant disease outbreaks in the United States and continue to pose a significant risk. The most frequently reported waterborne ...

  • Roughing filtration as an effective pre-treatment system for high turbidity water

    Effective water treatment is the prime goal of every water treatment facility. Chakwal Water Treatment Plant in Pakistan has been treating high-turbidity surface water through crude coagulation, sedimentation and slow sand filtration since the early 1980s. The process has always been tedious in terms of high coagulant dosage, large volumes of sludge and short filter runs especially after wet ...

  • Comparing plain and coagulated horizontal flow roughing filtration for high turbidity water

    In this work, a multi-compartment, horizontal flow roughing filter (HRF) was designed, constructed and operated to evaluate its effectiveness against high turbidity surface water with and without coagulation. The objective was to evaluate the efficacy of the HRF in removing turbidity, total organic carbon (TOC), total coliform and particulate matter. The HRF was operated at filtration rates of ...

  • Pulp & Paper Water Treatment - A look at optimizing water resource management

    Application Case Study (Pulp/Paper Operations) The pulp and paper industry has traditionally been a consumer of large amounts of fresh water and power. Recently, increased focus has been given to the optimized efficiency of paper mills and to the environmental sustainability footprint of the industry. Therefore, water resource management has become a more critical factor ...

  • Multi-barrier water treatment cleans up turbidity spikes

    When the City of Bloomfield, N.M., was notified by the New Mexico Environmental Department that it had 18 months to bring its drinking water treatment plant into compliance with the Interim Enhanced Surface Water Treatment Rule (IESWTR), they needed a fast, innovative solution. Under the IESWTR, the city was challenged to meet regulatory compliance on turbidity levels. During seasonal runoff ...

  • Understanding Crossflow Filtration

    There's a lot of attention being given to water availability and purity, with good reason. Obtaining enough water is a struggle in some areas. In others, water is tainted with contaminants. It is therefore predictable that regulations and economics will force careful water treatment and stress water re-use. Fortunately, there are water treatment methods that can help you meet the water quality ...


  • Industrial Media Filtration Systems, Philippines

    INTRODUCTION In July 2013, Pure Aqua successfully manufactured industrial media filtration systems to a major company in Philippines to remove particulates, chlorine, organics, and odor from well water. The industrial media filtration systems were selected from our MF-1000 Series with 48" and 42" diameter ...

  • Flotation outperforms sedimentation and ultrafiltration for turbidity and NOM removal at the drinking water treatment plant of Kluizen

    The drinking water plant of Kluizen treats surface water with high levels of organics and alkalinity. In the original plant, built in 1974, sludge blanket clarification followed by filtration was applied for floc removal. In 2008, the plant was extended with two additional treatment lines where flotation is used instead of sludge blanket clarification. Flotation-filtration proved to be very ...

  • Clarifiers-No, Filtration-Yes: A Case Study

    Problem Twenty miles southeast of Coos Bay, Oregon situated at the conjunction of the North and South Forks of the Coquille River lays the town of Myrtle Point. Just five years ago this community of 2670 residents was facing a large potable water problem with an even larger price tag. The town feeds its water treatment plant from the North Fork Coquille River. Prior to the 1990s the water ...

  • Removal of Giardia spp. and Cryptosporidium spp. from water supply with high turbidity: analytical challenges and perspectives

    Giardia and Cryptosporidium species are a serious problem if present in water supplies. The removal of these protozoans and the adaptation of existing protocols are essential for supplying drinking water to developing countries. Considering this, the aim of this study is to evaluate, on a bench level, the removal of Giardia spp. cysts and of ...

  • Home water treatment by direct filtration with natural coagulant

    ABSTRACTSeeds of the plant species Strychnos potatorum and Moringa oleifera contain natural polyelectrolytes which can be used as coagulants to clarify turbid waters. In laboratory tests, direct filtration of a turbid surface water (turbidity 15-25 NTU, heterotrophic bacteria 280-500 cfu ml−1, and fecal coliforms 280-500 MPN 100 ml−1), with seeds of S. potatorum ...

  • Strategies of coagulant optimisation to improve the removal of turbidity and Ceratium hirundinella cells during conventional drinking water purification

    The dinoflagellate, Ceratium hirundinella (C. hirundinella) cells are known to cause many problems when source water due for purification contains relatively high concentrations. The objective of this study was to investigate strategies for the effective and simultaneous removal of turbidity and C. hirundinella cells using turbidity and total photosynthetic ...

  • Experimental evaluations of water treatment systems using a pilot-scale plant for adaptations to a sharp increase in raw-water turbidity caused by climate change

    One effect of climate change on the water supply systems in Japan may be a sharp increase in the raw-water turbidity following heavy rain. The objective of this study was to evaluate water treatment performance with a sharp increase in raw-water turbidity. This evaluation was carried out from the perspective of turbidity response by a pilot-scale plant using sand filtration and membrane ...

  • Hybrid filtration method for pre-treatment of stormwater

    In this study the hybrid filtration process (combining fibre filter with deep bed dual media filtration) was investigated as pre-treatment to stormwater. This process was investigated in-terms of reduction in turbidity, dissolved organic carbon (DOC), colour, headloss development across the filters, suspended solids removal, organic matter removal, nutrients and heavy matter (such as iron, ...

  • POE sediment filtration — your first line of defense

    Around the country, our aging water delivery infrastructure is coated with sediment and scale from a century or more of buildup. Those same tuberculated pipes are constantly challenged by daily tie-ins, repairs, flow tests and fire hydrant use in most cities and towns. The result is that drinking water that left the municipal treatment plant at top quality arrives in users’ glasses — or in their ...

  • Industrial Skid Mounted Filtration System, USA

    INTRODUCTION In April 2013, Pure Aqua successfully manufactured and supplied to a major wastewater treatment site in the USA with a skid mounted twin alternating multi-media water filtration system to remove suspended solids from well water. The multi-media filtration system comes complete ...

  • Gravity driven membrane filtration system to improve the water quality in rainwater tanks

    The characterisation of rainwater in metropolitan Sydney and in rural New South Wales was undertaken. The results showed that factors such as the lack of vehicular traffic, air pollution and urban contamination meant that rural rainwater water quality was better. The rain water collected in both metropolitan and rural areas generally complied with the 2004 Australian Drinking Water Guidelines ...
