SPECTRAGUARD chemical "scale inhibitors, " prevent mineral deposits from building on your membrane, causing fouling. Our VASU-PWT product line helps resolve these problems-and in almost every instance, at a lower cost than it would be to use ion exchange to remove hardness.

RO MEMBRANE CLEANING
When a membrane does need cleaning, our VASU-PWT chemical product line removes most foulants and restores performance in all types of membrane systems. We can provide you cleaning chemicals specifically formulated to remove mineral scale, insoluble scale, organic fouling or microbial residue.

Flash steam can be effectively recovered by using a Condensate Flash Vessel as a part of a Flash Steam Recovery System. The flash steam is free steam and can be used to supplement the normal steam requirement. Flash steam should be separated from the condensate to maximise the system''s efficiency. Since the flash steam is utilised, it will not be vented to the atmosphere where it is wasted and can be a safety hazard.

Hot condensate still contains 20% of the energy you used to make steam in the first place. And since condensate is distilled water, it makes perfect boiler feedwater. Our positive displacement pressure Powered Pump is the heart of a money and energy saving Condensate Return System.The PPPU pumps condensate at 100 oC without electricity, using just a small blast of steam or air pressure, even under vacuum and stall conditions. Due to its sealed & gland-less design, the collected condensate can be pumped immediately, without waiting for it to cool, and with no risk of cavitation

Pressure Powered Pumping Packaged Unit (PPPPU)

Pressure Powered Pumping Packaged Unit is a positive displacement pump unit operated by steam, compressed air or pressurized gas. The unit is specifically designed to pump hot liquids of specific gravity 1.0 down to 0.9.

Condensate Recovery (CRM) is also an integral part of the PPPPU. It is an effective management tool which not only shows the condensate quantity & condensate temperature, but also shows the energy saved through condensate return.

Together, this unit is a complete solution to collect condensate, pump it to desired level and destination, to measure the condensate temperature and meter the condensate quantity. PPPPU has to be preceded with properly sized flash vessel depending upon the condensate parameters.

Fitted on your feedtank, the FORBES Deaerator Head mixes cold make-up water, hot condensate, and flash steam in a single stainless steel (SS) head to get the most out of your captured heat.Cold make-up water atomizes in the mixing head releasing 90% of dissolved oxygen, a primary source of downstream corrosion. The single head design eliminates the need for cumbersome spurge pipes.

FORBES Disc Check Valves are recommended after traps discharging into closed systems to guarantee against return or spill back. DCVs feature a compact and rugged stainless steel design and are suitable for any process liquid & gas, not just steam. Main advantage of these check valves is they can be mounted between pipe flanges in any direction.

DCV 1, 2, 3
DCV 1, 2 and 3 Disc Check Valves are designed to be sandwiched between flanges i.e. wafer type. They are suitable for use on a wide range of fluids for applications in process lines, hot water systems, steam and condensate systems etc.

DCV 4 Wafer Check Valve
The DCV 4 Disc Check Valve is designed to be sandwiched between ANSI flanges. It is suitable for use on a wide range of fluids for applications in process lines, hot water systems, steam and condensate systems etc.

One FORBES Strainer upstream of every trap, control valve, and flowmeter can save you a bundle in annual maintenance and wear & tear costs. Available in Y or T type designs, our Strainers remove suspended grit from steam and condensate that would otherwise damage your downstream equipments with no additional pressure drop.

FORBES Marshall brings to you the Automatic Pumping Trap - the world's smallest condensate drainage system that works under all the load conditions, even vacuum. It's compact design makes it convenient to install within 200 mm of the installation head. The Automatic Pumping Trap is fully mechanical with no requirement for electrical power, pnuematic supply, motors or level switches.

What do you mean by Stall ?
Stall is the reduction or the cessation of condensate flow from the steam space, and occurs when the pressure in the steam space is equal to, or less than, the total backpressure imposed on the steam trap.

Northman starts water treatment with boiler water treatment, and more than 15 years ago, we began treating boilers for industry. And that long-term commitment to developing the most innovative boiler water treatment technologies in the industry continues today. It is a result of our desire to improve your competitive advantage and decrease your total operating costs.
A single day of lost steam production can cost you much more than the cost for one or two years of our boiler water treatment programs. While our program costs may not significantly impact your bottom line, we understand that our results do, and we are passionate about helping you produce reliable, safe, and cost-effective steam. Successful boiler operation requires a total system approach to:

• Prepare feed water before it goes to the boiler
• Protect and keep the internal boiler surfaces clean
• Maximize condensate return

We can perform detailed system audits and diagnostics in association with our principals who are leaders in water and steam to prescribe the best chemical, steam distribution and service programs to maximize your boiler system performance and efficiency through an effective boiler water treatment program. Through utilizing our innovative programs, we can help you achieve water and energy savings, asset preservation, and increased plant reliability and safety.

VASU-NORTHMAN understands that effective primary waste water treatment is critical to your plant operations, whether you are discharging directly to a municipal wastewater treatment system or treating prior to your own biological wastewater treatment system. Optimizing the performance of treatment chemicals and equipment can dramatically minimize overall costs and maximize your return on investment, and we can provide creative solutions to help meet your most stringent water quality requirements.
Solids dewatering is the second-highest cost area in a wastewater treatment plant, second only to electrical utility costs. Effectively optimizing the performance of dewatering equipment and chemicals can dramatically minimize the total cost of operation and maximize your return on investment. In addition, as processors endeavour to meet stringent regulatory requirements, solids handling and disposal continues to be one of the most important areas requiring creative, sustainable-technology solutions.
We also understand that effective secondary wastewater treatment is critical to your plant operations. We can provide you with creative treatment chemicals and equipment solutions, helping you meet your most stringent water quality requirements and maximize your return on investment. Our programs typically focus on the following and can help you with:

• Improving overall plant economics
• Increasing operator capabilities and effectiveness

The FORBES pressure reducing station is an engineered and factory assembled unit. It is designed in line with good steam engineering practices using our proprietary software. FORBES Marshall manufactures all the components of the pressure reducing station in-house, which enables quality control for each component to FORBES standards. Every component is tested on live steam & the entire assembly is hydro tested.
