  • How industrial water filtration can improve efficiency and save you money

    Over the course of the past couple of decades, industrial water filtration has become one of the most important considerations for the average manufacturing facility in North America. These concerns have only increased as water supplies have dwindled and wastewater contamination standards have become more stringent. All of this has led to the need to choose the right industrial water filters and ...

  • The ecological filter system for treatment of decentralized wastewater

    A vertical flow constructed wetland was combined with a biological aerated filter to develop an ecological filter, and to obtain the optimal operating parameters: The hydraulic loading was 1.55 m3/(m2·d), carbon–nitrogen ratio was 10, and gas–water ratio was 6. The experimental results demonstrated considerable removal efficiency of chemical oxygen demand (COD), ammonia nitrogen ...

  • What is Wastewater?

    What is wastewater? Wastewater, the waste discharge that first comes to mind in any discussion of stream pollution, is the discharge of domestic wastewater, which contains a large amount of organic waste. Industry also contribute substantial amounts of organic waste, some of which comes from vegetable and fruit packing; dairy processing; meat packing; tanning; processing of poultry, ...

  • Treatment of Spent Filter Backwash Wastewater Using Dissolved Air Flotation Process

    Spent Filter Backwash Water (SWW) is a major recycle stream that accounts for 10% (about 30 mgd) of the average flow at Blue Plains Advanced Wastewater Treatment Plant (AWTP) and a similar proportion of nitrification and denitrification treatment process capacity (DCWASA Focus, November 2004). The peak SWW flow and load result from increased filter washing during high flow events. The combined ...

  • Performance of a biofilter system with agave fiber filter media for municipal wastewater treatment

    Agave plants grow in semi-arid regions and are used for mescal production. However, agave fiber by-products are considered waste materials. Thus, we tested agave fiber as a filter media and biofilm material carrier for removing pollutants from municipal wastewater. Three laboratory-scale biofiltration reactors were used in two trials with five hydraulic loading rates (HLRs = 0.27, 0.54, ...

  • Micro-90 Effective Filter Membrane Cleaner for Wastewater Treatment Operations

    The care and cleaning of filter membranes is essential to the success of many water treatment systems.  International Products Corporation (IPC) manufactures a line of membrane cleaners effective at restoring 100% flux at safe pH ranges.  One of IPC’s customers treats industrial wastewater generated by the engine plant of a major automotive ...

  • Application of Biotrickling Filter for Odor Control at The Morris Forman Wastewater Treatment Plant

    Pilot-scale study of a biotrickling filter using synthetic, high surface area media was undertaken by MSD Louisville, with the intention of saving the high cost of operating thermal oxidizers. Currently, two recuperative thermal oxidizers are used to treat odorous emissions from various sources. The pilot study showed that it is possible to treat hydrogen sulfide and organic sulfur compounds at ...

  • Case study - Upper Uvdal wastewater treatment plant - Filter bed

    The plant is designed as a traditional chemical and biological treatment plant, as a polishing step the effluent is going thru a filter bed with Filtralite before it is discharged into a small creek. The filter bed treatment plant is built with Filtralite P in Nore and Uvdal municipal in Norway. Uvdal ski resort, some houses and several hundred holiday homes are connected to the treatment plant. ...

  • Wastewater treatment in an anaerobic filter using small lava stones as filter media without temperature control

    For their simplicity and using cheap support materials, biological filtration of municipal wastewater can be adequate for developing countries where the legislation is not as strict as in other countries, like the members of the European Union. Biological filters are fixed biomass reactors where the suspended pollutants can easily be retained and the dissolved substances can be transformed by ...

  • Advanced Enviro - Septic™ Wastewater Treatment System Septic Tank Effluent Filters and Charco al (Odor) Filters NOT Recommended

    Abstract: Effluent filters are installed in the outlet from the septic tank with the intended purpose of retaining solids inside the tank, preventing them from entering the treatment system and/or dispersal field. The concern is that if solids escape from the septic tank, they could cause clogging of the system components or the soil interface. While this may be a legitimate concern for some ...

  • Peach Processing Wastewater Treatment

    A major fresh pack operation of peaches and nectarines needed a screening system to remove the labels and peach fuzz from their wash water before it was pumped from the pond for irrigation use. Flow to the pond is a steady flow of 50 gpm, rising to 600 gpm during periodic draining of the peach coolers and washing systems. The water is a combination of wash water, labels and fuzz from the fruit, ...

  • Times are changing: Wastewater as a resource

    Times are definitely changing. It used to be that wastewater from whatever source – domestic, agricultural, industrial – was something to collect and pipe away as quickly and efficiently as possible. There was more water coming out of the ground or falling from the sky, so why bother investing time and money cleaning water that had already been used? Now, thanks to issues like ...

  • Treatment of industrial wastewater

    All industries produce some type of waste product, either from production, maintanance or both. These hazardous and non-hazardous wastes need to be properly stored, treated and discharged to a sewer system or otherwise disposed of. Wastewater treatment is a multi-stage process to renew wastewater before it is discharged to the municipal sewer system. The goal is tio reduce or remove organic ...
