  • 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 ...

  • Two phase partitioning bioreactor applied to produced water treatment

    Produced waters are the largest waste associated with the production of oil and gas; they contain dissolved salts, oil (dissolved and scattered organic compounds), chemicals and additives involved in the oil well operations, suspended particles, sand and other compounds, making their treatment very complex. In this paper, we propose the use of a TPPB (two phase partitioning bioreactor) for the ...

  • Wastewater Treatment & Recycle

    Fresh water is a scarce commodity; this fact is well acknowledged by one and all. People at all levels be it general public, governmental bodies, and industries understand the implications of good quality water availability in terms of quantity, cost and wastage. As a consequence, there is a growing consensus on wastewater treatment for recycle/reuse. This paper briefly describes the treatment ...

  • Using Nanofiltration in Beverage Production

    The following article is based on a paper presented in August, 1990 at the 21st Annual Meeting of the Fine Particle Society in San Diego. Soft drink manufacturers, not to mention manufacturers of other beverage products, have always had a keen interest in the water that goes into their products. After all, it is the water that typically makes up 80%-90% of the product. In the past the water has ...

  • On-site industrial wastewater treatment

    Priority pollutant behaviour in on-site treatment systems for industrial wastewaters The majority of wastewaters deriving from the chemical industry consist of aqueous discharges produced during the physico-chemical processing of synthetic mixtures involving operations such as filtration, centrifugation, extraction and/or distillation. The wastewater streams, referred to as ...

  • The biological basis of wastewater treatment

    Introduction This booklet was written to fulfil the need for a simple explanation of the biological processes that underpin wastewater treatment. It attempts to show how the bacteria involved deal with the organic carbon in the sewage. Remarkably, there are just 3 major processes involved, and these mirror exactly the 3 major processes at work in the plant viz: biodegradation, oxygen ...

  • Production of lacquers and paints

    During the production of lacquers and paints you can use an intensive dispersion of solid phase and contemporaneous activation of particles. The time of dispersing of the ferrate pigments in the Intensifier of Technological Processes is 15-60 seconds. During this time the ferrate pigments disperse to the size of 20 micron. At the ball ...

  • Optimizing water management in hydraulic fracturing for shale oil and gas production

    Centralized treatment of wastewater is emerging as a viable solution for long-term efficiency in managing water sourcing and wastewater treatment in hydraulic fracturing. The number of hydraulic fracturing (fracking) shale oil and gas wells in the United States continues to increase. Within the Bakken Shale formation alone, in North Dakota and Montana, upwards of 15,000 hydraulic fracturing ...

  • Thermal Treatment Technologies

    Hot gas decontamination: Hot gas decontamination is a technology still in the pilot-scale of development that can be used for decontamination of explosives-contaminated masonry or metallic structures. The method involves sealing and insulating the structures, heating with hot gas stream to 260 °C (500 °F) for a prescribed period of time, volatilizing the explosive contaminants, and destroying ...

Chosen for Florida’s “Green House project “ in the USA .. as the preferred water treatment for the Argentine Central Bank ,  and also the City Mall in Jordan Fluid Dynamics ...

  • Behaviour of brominated and chlorinated flame retardants during drinking water treatment

    Flame retardants are chemicals that are added to plastic materials in order to prevent them from catching fire and to slow down the burning process. Due to the widespread occurrence of flame retardants in the environment, it can be expected that especially the more hydrophilic compounds already contaminate raw water resources of water utilities. In this paper results of laboratory-scale ...

  • Effects of temperature on type approval testing of ballast water treatment systems

    In order to limit the risk associated with invasion of habitats by exogenous species, the International Convention for the Control and Management of the Ships' Ballast Water and Sediments was adopted in February 2004 and may soon enter into force. The International Maritime Organization (IMO) has produced guidelines to assess the efficacy and reliability of Ballast Water Treatment Systems ...

  • In Search of Ideal Groundwater Treatment

    As surface water supplies become increasingly polluted and difficult to treat, the use of groundwater continues to increase. Every day, more than 77 billion gal of water are withdrawn from aquifers for a variety of uses including human consumption. Worldwide, groundwater makes up 95% of available freshwater, and nearly half of the U.S. population receives all or part of its drinking water from ...

  • Adsorption of colloidal particles of Moringa oleifera seeds on clay for water treatment applications

    This work was designed to produce microparticle composite systems from Moringa oleifera seed powder and clay microparticles (CMPs) for use in water treatment applications. Adsorption and immobilization of M. oleifera cationic protein (MOCP), obtained from the seed powder, onto core anionic CMP was carried out in a batch process. The CMP was incubated with MOCP and the ...

  • Do You Need a Raw Water Treatment System for Your Plant?

    Determining whether or not you need a raw water treatment system for your industrial facility can be a difficult decision. But if your plant draws from a raw water source (such as a river, lake, ocean, or groundwater), chances are you will need some sort of treatment. If left untreated, what is present in your water source can cause a variety of issues, such as contamination in drinking water ...

  • Algae and Biofilm control project for a drinking water treatment plant in Cyprus

    For the Ministry of Agriculture in Cyprus, LG Sound b.v installed 33 LG Sonic, ultrasonic devices in the Limassol water treatment plant, to prevent bad odour and taste to the water caused by geosmins in the water. The earthy taste problem persisted during summer of 2010 and various physical, chemical and biological tests were done in order to check the process efficiency, which showed ...
