  • Common Treatment Train for Fuels

    A treatment train is the combination of different treatment technologies. A system diagram of a common treatment train for fuels is illustrated below. The fuel contaminated soil is first treated using a soil washing process. Water is injected at the up stream side of the contaminated site. Surfactant or other additives may be added to enhance the soil washing effect. Contaminated water is ...

  • Common Treatment Train for Halogenated VOCs

    In general, no single technology can remediate an entire site. Several treatment technologies are usually combined at a single site to form what is known as a treatment train. A system diagram of a common treatment train for halogenated VOCs is illustrated below. A ground water pumping system is used to pull contaminated water from the subsurface. The VOC contaminated water is pumped to a liquid ...

  • Common Treatment Train for Nonhalogenated VOCs

    A treatment train is the combination of different treatment technologies. A system diagram of a common treatment train for nonhalogenated VOCs is illustrated below. A soil vapor extraction system is used to pull VOC vapor from the contaminated soil. An air sparging system delivers air below the water table to enhance bioremediation. After passing through a liquid/vapor separator, the VOC ...

  • Potable reuse treatment trains throughout the world

    Potable reuse is becoming an increasingly common strategy for bolstering water resource portfolios in water-scarce regions. Each application poses unique challenges, whether related to treatment goals, regulatory requirements, or political and public acceptance, and these issues have a significant impact on the final treatment train selection. This review describes the various potable reuse ...

  • Water reuse technology trains for medium-level water

    Wastewater is considered as stable and substantial amount of alternative water resource. In case of South Korea, it is known that 73.2 percents of supplied water discharge 16 million m3/day of treated effluent from municipal wastewater treatment plants. Calculation simply tells that 0.58 billion m3/year can be available if only 10 percent of wastewater could be reused. In this study, a pilot MBR ...

  • Tracking disinfection by-products and arsenic removal during various drinking water treatment trains

    In the central Banat region (Northern Serbia), groundwater is used as a drinking water source. Raw water originates from a 40–80 m and 100–150 m deep layer. It contains a high amount of natural organic matter (DOC = 9.17±0.87 mg C/L) with a trihalomethanes formation potential of 448±88.2 μg/L and a haloacetic acid formation potential of 174±68.9 μg/L. A high amount of arsenic (86.0±3.4 μg/L) is ...

  • Zhuhai --a membrane based water treatment plant

    The Facility At the time it was built, the Guangdong Zhuhai Power Station set a number of firsts for China. Not only was it the largest thermal power plant in terms of unit size , it was the first to use Reverse Osmosis Water Treatment and it was the first to be financed without a multilateral or government guarantee. Zhuhai was also EPC Mitsubishi Heavy Industries’ first turnkey ...

  • Simulation for Operation and Control of Reject Water Treatment Processes

    The recycled nutrient load of the reject water streams from solids handling is considerable, and can amount to 15-25% of the influent nitrogen load. A number of sidestream biological processes have been developed for treating the ammonia component of the reject water before returning it to the liquid train. This paper describes a plant-wide model that includes the reactions important in ...

  • Unique Ozone and Ultraviolet Water Treatment System

    Euroby Ltd, the sludge treatment specialists, are pleased to announce the signing of an agreement to be the sole UK and Ireland distributor for the unique UVOX range of water treatment  systems.UVOX, as the name suggests, uses a combination of Ultraviolet and Ozone to treat infected and polluted water.Its uniqueness stems from its novel method of first producing ozone by irradiating air with a ...

  • BP Petrojarl Foinhaven - produced water treatment

    Client: BP/PGS Petrojarl Foinaven - UK CETCO were approached by BP/PGS regarding potential fluids handling problems on the Petrojarl Foinaven FPSO when bringing on two new wells during September 2001. CETCO mobilised a RFV 4000 DF Adsorption Skid containing CETCO’s patented CrudeSorb® media to treat the oily water phase of the well returns for discharge directly overboard. During a two week ...

  • Ozone is Not Just for Residential Potable Water Treatment

    It has been over 170 years since the d iscovery of the ozone (O3) molecule. Since that time, scientists and engineers have been testing and evaluating ways to use ozone in many different processes, from water and air treatment to surface and food sanitation. The evolution was somewhat slow in the early days, taking nearly 50 years before Europeans found, in 1886, that ozone could be used for ...

  • Recycle of waste backwash water in ultrafiltration drinking water treatment processes

    In drinking water treatment, ultrafiltration (UF) membrane systems are generally operated at 90 to 95% recovery with production losses resulting from waste residual streams such as backwash water and clean-in-place (CIP) liquid residuals. In drought-prone regions, it may be desirable to apply alternative UF plant design configurations to increase recovery rates and minimize water loss. This ...

  • Expert On-the-Job Training and the Aging Workforce

    ABSTRACTApproximately seven years ago, the Metropolitan Sewer District of Greater Cincinnati-Wastewater Treatment Division realized there was no standardized training system in place and there was no gauge to measure the success of the training being performed. It also realized it had an aging workforce that is now nearing retirement and the knowledge that could ...

  • Removal and relationships of microbial indicators in a water treatment and reclamation facility

    A wastewater treatment and reclamation facility in north-east Spain was monitored over 1 year to determine the occurrence and concentrations of different microbial indicators (Escherichia coli, fecal enterococci, somatic bacteriophages and spores of sulfite-reducing clostridia). The removal of the indicators and its relationships through the wastewater treatment and reclamation trains were ...
