When doing more of the same is not enough

Introduction

Water…life depends on it. And although about 70 percent of the earth’s surface is covered with water, more than

two billion people are deprived of a constant and reliable source of drinking water on a daily basis. Worldwide,

governments, municipalities and industries face the challenge of safeguarding current and future drinking and

process water requirements. These dire circumstances cannot be tackled simply by doing more of the same; they

require new visions and cutting-edge innovations. This is why Norit X-Flow, the world’s leading ultrafiltration (UF)

technology company for both small and large scale systems, is constantly investing in research and development

to increase the performance and efficiency of our proven technology and pioneering new solutions for water

purification.

One of Norit’s answers to the world’s water crisis is our advanced engineering upgrade to the Norit Aquaflex™

UF system. With our proven membrane technology at its core, the Norit Aquaflex™ is the best performing water

treatment system at a considerably lower total cost of ownership. Addressing the emerging legislation for turbidity

and microbiology, the Norit Aquaflex™ system provides superior separation performance and effectively rejects

viruses and chlorine resistant organisms, such as Cryptosporidium and Giardia.

As your partner in providing clean water for the world, Norit X-Flow helps you create more value using fewer resources in your on-

going effort to meet sustainability goals. After all, sustainability means conducting activities smartly and efficiently in ways that are

economic, renewable and repeatable. This is why Norit X-Flow mobilized its widely renowned research and development capabilities to

systematically identify breakthrough opportunities in each of its primary product markets. What resulted is Norit’s Efficient Performance

Technology, a mark of excellence that assures our customers are getting the best performance without compromising the environment

and their financials.

Putting the Efficient Performance Technology approach to work for the Norit Aquaflex™ system resulted in a higher output volume and

leading membrane separation performance while lowering the CAPEX/OPEX balance, decreasing the system footprint and reducing

energy and chemical use and waste production. For you this means a reduced financial, physical and environmental plant footprint

while producing the highest performance and quality.

Efficient Performance Technology

UF Water Treatment

Feed Permeate

The newly upgraded Norit Aquaflex™ UF system combines the vertical design of Norit Aquaflex™

inside-out technology with the advantages of a minor bleed flow across the membrane surface as

well as a module with a larger surface area. This allows your system to be designed with

higher flux rates, reduced footprint and the flexibility to treat a broader range of feed water

qualities.

By applying a minor bleed flow, the fouling layer on the membrane surface is minimized and the

fouling potential of the membranes is significantly reduced. Consequently for similar feed water

qualities, Norit Aquaflex™ provides higher fluxes, longer filtration times, less membrane cleaning,

and higher recoveries, which means lower investment and operational costs.

The bleed flow is typically 5-10 percent of the permeate flow and is

normally fed back directly to the feed. For small systems the bleed

flow is fed back to the feed tank. For larger systems a small dedicated

circulation pump is incorporated into the skid design. Even for feed

water with high turbidity, outside the acceptable range for normal

dead-end operation, Norit Aquaflex™ can be used by discharging a

portion of the bleed flow instead of recycling to the feed.

The new Norit Aquaflex™ system integrates Norit Smart Technology,

a newly developed automated intelligence algorithm that ensures

maximum system performance and run-time while minimizing the

energy and chemical usage. The system can respond in real-time to feed

water quality and system changes by adjusting settings as needed, thus

eliminating excess energy and chemicals. Norit Smart Technology

automatically optimizes the actual performance of the installation in

real-time.

Sustainable DesignAs a result of the “Efficient Performance Technology” approach, Norit Aquaflex™ strengthens its leading position in the water treatment

field by delivering an overall output increase of 75% per module.

Although great alone, the best performance is achieved when the new Norit Aquaflex™ module is used with the new Norit Aquaflex™

skid design, which standard incorporates Norit Smart Technology. With its excellent modular characteristics the Norit Aquaflex™ skid

offers a nominal capacity of up to 800 m3/h by featuring up to 6,600 m2 of premium membrane surface. The new skid layout represents

a considerable footprint reduction and provides convenient accessibility to all modules for fast construction and maintenance.

Unmatched Excellence

The Norit Aquaflex™ design delivers unequalled performance and efficiency ratings

in the production of potable and process water, pre-treatment of seawater and

wastewater treatment. Norit X-Flow’s innovative membrane technology is currently

used in over 40% of the largest UF plants in the world demonstrating our know-

how to design, manufacture, implement, and commission water systems that push

the envelope on both efficiency and performance.

Global Service Management

Advanced Technology

Today, service is much more than just repair and maintenance. Service contracts are an integral part of your preventive maintenance

program. During project management, Norit’s service team is introduced to the customer and assists with commissioning. On-site the

service team gathers valuable information about the local conditions of the operation. With performance data monitoring, we are able

to acquire long-term data, which ensures that troubleshooting and service activities can be very efficient and to the point in case of an

emergency. By taking advantage of the full service contract a company can be assured that the potential for continuous improvement of a

plant is explored on a regular basis and place its focus on the core business.

Norit’s lifecycle/service management can be divided into two phases: design and operation. Proposal/planning, contract management, and

engineering up to commissioning are typical design services. Start-up, monitoring, consulting (24/7 helpdesk), maintenance/ replacement

of components, evaluation and optimization are part of the operation services. The overall goal is to secure that an operation is running in

the best possible and most cost-efficient way.
