  1. Automated Tubular Backwash Filtration: A Smarter Approach to Industrial Water Management

    Comments Off on Automated Tubular Backwash Filtration: A Smarter Approach to Industrial Water Management

    Industrial facilities are under growing pressure to reduce water consumption, control wastewater costs, minimize maintenance, and improve process reliability. SIGMA Design Company’s Automated Tubular Backwash Filter Systems provide an engineered approach to these challenges by combining filtration, automation, solids concentration, and water recovery into one integrated solution.

    Unlike traditional bag and cartridge filters that rely on disposable media, SIGMA’s tubular filtration systems automatically backwash to remove accumulated solids while maintaining the filtration process. The result is clean water that can be reused or returned to the process, along with a concentrated solids stream that can be directed to or integrated into existing solids-handling equipment.

    SIGMA Design Company’s Automated Tubular Backwash Filter Systems provide continuous, automated filtration for demanding industrial water applications designed for process water, water reuse, cooling water, and solids concentration, the system removes suspended solids while reducing reliance on disposable filter media.

    SIGMA’s systems can be customized to meet specific flow, filtration, footprint, and controls

    requirements. Applications include cooling tower side stream filtration, heat exchanger and spray nozzle protection, food processing wash-water reuse, plastics recycling wash water, and pretreatment for membrane and DAF systems.

    What sets SIGMA apart is our engineering-led, turnkey approach. Rather than simply supplying a filter, SIGMA can design and manufacture complete skid-mounted systems with PLC/HMI controls, multiple filter configurations, solids dewatering integration, and water recovery. With in-house engineering and manufacturing support, customers gain a single partner capable of designing, building, testing, and supporting the complete system.

    SIGMA Automated Tubular Backwash Filter Systems provide an intelligent alternative between standard catalog filters and costly custom-engineered filtration projects— helping industrial facilities recover more water, manage solids more effectively, reduce consumables, and improve overall process efficiency.

     

  2. Sigma Design Company’s New Industrial Water Systems

    Comments Off on Sigma Design Company’s New Industrial Water Systems

    Industrial facilities today are demanding higher efficiency, tighter water quality control, and more reliable system uptime than ever before. For customer engineers in the water filtration sector, the pressure is clear: filtration performance must be smarter, more integrated, and more sustainable across the full process water lifecycle.

    Water is the quiet workhorse of modern industry. It cools, cleans, transports, and transforms—but it also represents one of the biggest operational costs and sustainability challenges many manufacturers face today.

    At Sigma Design, we’ve answered this demand with a new suite of industrial water system solutions purpose-built for filtration-intensive operations—from high-purity process water to closed-loop cooling and water reuse applications. This new platform focuses on modularity, energy efficiency, and advanced controls to help engineers deliver measurable value to their plants or clients.

  4. New Industrial Product Release Differential Pressure Alarm System

    Comments Off on New Industrial Product Release Differential Pressure Alarm System

    A New Differential Pressure Alarm System With Communications Module Model DPC-4570

    Differential Pressure Alarm Panel

    DPC-4570 SPECIFICATIONS:

    The new SIGMA DP Alarm Panel is ready to satisfy your Differential Pressure monitoring needs. The Differential Pressure (DP) Alarm Panel is a simple, easy to install and configure solution to monitor the pressure drop across a filtration media or other pressure sensitive processes. It is suitable for liquid and gas process systems.

    Using our HMI Touch Screen, the user can easily:

    Monitor inlet/outlet pressure on a continuously updating display with 0.1 PSI accuracy both locally and remote.

    • Dynamically adjust the DP alarm setpoint.
    • Monitor the current DP up to 20 PSID. A red LED stack light will turn on when the current DP pressure exceeds the setpoint value. The light can be configured to turn on solid or blink.
    • An optional audible alarm module can be added for non-visual indication. Additionally, a “dry” set of relay contacts will close (Ø1, 6A, 250 VAC). These contacts can be used to power ancillary equipment or remotely communicate with other industrial systems.

    Why Monitoring Differential Pressure is Crucial in Process Applications:

    Safety: Differential pressure measurement can also play a vital role in ensuring the safety of a process. By monitoring pressure differentials, operators can take immediate action to prevent accidents, equipment damage, and potential harm to personnel.

    Efficiency: By monitoring differential pressure with the SIGMA DP Alarm Panel, you can assess the efficiency of the fluid process and identify potential issues such as blockages, leaks, or flow restrictions. This information can help optimize the process to ensure that it operates at its maximum efficiency.

    Quality Control: In industries where precise control of fluid flow is essential for maintaining product quality, monitoring differential pressure becomes critical. Deviations in pressure can indicate changes in the composition, viscosity, or density of the fluid being processed, which can affect the quality of the end product. Regular monitoring with the SIGMA DP Alarm Panel allows for quick detection and correction of any issues that might compromise product quality.

    Process Control: Many industrial processes require precise control of fluid flow rates to achieve desired outcomes. Using the SIGMA DP Alarm Panel, operators can adjust control valves and other equipment to maintain the desired pressure differentials, thus ensuring that the process operates within the specified parameters.

    Equipment Health Monitoring: Changes in differential pressure can often signal equipment wear and tear or clogging. By regularly monitoring pressure differentials across filters, heat exchangers, and other components, maintenance teams can schedule preventive maintenance activities, reducing the likelihood of unexpected breakdowns and downtime.

    Energy Efficiency: In systems where pumps and compressors are used to maintain fluid flow, monitoring differential pressure with the SIGMA DP Alarm Panel can help optimize energy consumption.

    Regulatory Compliance: Is your industry subject to strict standards related to process conditions? Differential pressure measurement can provide documentation of compliance by demonstrating that pressure differentials are being maintained within specified ranges.

    Troubleshooting: When an issue arises in a process, differential pressure measurement can provide valuable diagnostic information. The SIGMA DP Alarm Panel can detect sudden changes in pressure, which can help operators identify the location and nature of the problem, enabling faster troubleshooting and resolution.
