Design of industrial wastewater treatment plants: a multi-faceted problem

Wave Software For Water Treatment Plant Design

The plan is to extend that ethos to more readily available recyclable sources by 2020 – a mere few months away. At the confluence of the Appomattox and James rivers in Hopewell, Virginia, lies the Hopewell Water Treatment Plant, a century-old facility owned by Virginia American Water, a subsidiary of the largest investor-owned water/wastewater utility in the U.S. From this plant, more than 9,300 domestic and industrial customers were being served by obsolete systems and infrastructure, some of which dated back to the early 1900s. The first step is for us to evaluate your facility to identify optimal operational and control strategies. Next, we will co-create a TwinPlant installation that addresses your operational needs, with extra focus on specific concerns and bottlenecks. Customisation can be made at multiple levels including backend data processing, model execution, frontend user interfaces and more.

  • Seamlessly assimilate and validate data from multiple sources and apply them to advanced process optimisers for process control as well as online reporting.
  • However, further studies are needed to incorporate the safety aspect into HEN design using PA.
  • Whatever your water and specialty-separation challenges, we’re ready to provide our perspective, expertise, and solutions, so you can move forward.

  • All simulations were performed as steady-state simulations, with the convergence target of 10−4 achieved for the pressure and the flow velocities, and 10−6 obtained for the mass fraction of ions.

When the Chino Basin Desalter Authority wanted to implement a water treatment solution targeted around rejecting nitrates, the ideal reserve osmosis filtration system required very exact specifications across a multitude of dimensions. Approximately 75 percent of this water is pumped to the reverse osmosis system. Chemicals added before the reverse osmosis are antiscalant, and Sodium https://www.wave-accounting.net/ bisulfate. The antiscalant is added to prevent the calcium carbonate from forming a precipitate. Sodium bisulfate is added to remove any remaining oxidants that were not exhausted in the filter. Hollow-fiber technology (0.4 micron pore size) provides a positive barrier against viruses, turbidity, suspended solids, and pathogens while providing 97 percent overall system recovery.

As coal mine water often contains high TDS, the current study covers a wide range of TDS up to 25,000 mg/L. Figure 5 shows the position on the BW RO element with calcium sulphate being supersaturated for feedwater containing 10,000 mg/L of TDS and with a feed pressure of 15.16 bar. It can be seen that, with different initial calcium sulphate concentrations and feed velocities, the location on the membrane where calcium sulphate becomes supersaturated varies. With the initial calcium sulphate concentration of 600 mg/L, scale might form at 0.37 m from the inlet to the RO element at a feed velocity of 0.03 m/s.

This work presents a new method for HEN design that incorporates the inherent safety index during the selection of heat exchanger matches in order to reduce the potential hazards of the optimal HEN design. Application of the extended PA on a case study shows that inclusion of the inherent safety feature has managed to localise the area of hazards, reduce the requirement for special materials of construction, and ultimately reduce the HEN capital cost by 10%. Dow Water & Process Solutions (DW&PS) introduced Water Application Value Engine —a new digital modeling tool for evaluating components and designing water treatment systems.

TOOLS

Dow Water and Process Solutions has launched a new design software, water application value engine , which integrates multiple technologies into one tool. Get free access to a broad range of user-friendly digital tools that can help you, from optimizing membrane cost and carbon footprint in Desalination plants, to calculating when you need your next ion exchange resin replacement. Variations in feedwater temperature, salinity, or pump pressure can influence the apparent productivity and rejection of a membrane system, making it less obvious when a real change in membrane performance has occurred.

Wave Software For Water Treatment Plant Design

A novel process model is now present in WEST to provide a detailed description of the fate of ISS throughout the different units of a WWTP, eventually allowing for a more precise quantification of sludge handling and disposal costs. Determine energy balances and costs to identify pitfalls and inefficiencies in WWTP operations and assess optimisation potential. Support decision-making to increase efficiency and reduce energy Wave Software For Water Treatment Plant Design footprint in specific process units and at plant-wide level using detailed energy and cost calculations in WEST. Modelling of WWTP process dynamics requires high-frequency input time series, which may not always be available from on-site measurements. With WEST, you can define the time series for influent quantity and quality based on essential information in the served catchment and several pre-defined discharge patterns.
