About UPT

Complete Technologies

In order to achieve the client required level of purification, we take into consideration of elements such as the qua-lity of the feed water and its possible variations, client usage behavior, budget, constraints of the site, and other affec-ting factors or conditions, which are then analyzed to custom-design the most suitable pure water system that is stable and cost-effective. The successful appli-cation of various tech-nologies requires comprehensive and professional practical experiences. 
UPT adheres to and puts into practice the concept of striving for thoroughness and excellence. The systems we design, whether derived from our own R&D’s or in coope-ration with professional manufacturers, accom-plish unpa-ralleled results. Following are some of the commonly used water treatment technologies in the industry:

● Depth filtration: such as sand filters, multi-layer filters, activated carbon and so on.
● Full filter: cartridge filter such as general, absolute filtering.
● partial filter: such as ultra-filtration, micro-filtration.

● Single-stage reverse osmosis
● Two-stage reverse osmosis: combined pH adjustment or film degassing

United Purification Technology

Lewatit VWS Technology

Modern Lewatit VWS technology was first developed and patented by the Bayer Group in Ger-many. The technology is derived from the concept of counter-current regeneration. With its unique internal structure and design, the system provides the most efficient regeneration and best product water quality. Lewatit VWS Technology is currently the most-used system.
UPT has been authorized by the Bayer Group for the Ion-exchange technology since 1998. Combining technologies from Bayer and us and our working experiences, we have built many pure water systems with consistent water quality and reduced operational overhead and garnered ex-cellent praises from our clients.

Features and Benefits of Fluidised:
●Shorter regeneration time
●Lower consumption of service water
●Neutral resin preventing dispersing head from clogging
●Consistent product water quality, simple regeneration pro-cedure
●No regeneration backwash, smaller footprint, increased operating capacity
●Low regenerant requirement (about 1/2 to 2/3 that of a tra-ditional system)
●Fully automated water production and regeneration, thus reduced labor cost

Ultrafiltration Pretreatment

RO has played an important role in today’s ultrapure water systems. RO eliminates most of the im-purities from water, which include dissolvable solids, ions, bacteria, organics, silicon dioxides, etc. Therefore, how to keep a RO system in its ideal operation condition is a fundamental consideration in designing the system.Changing seasons often result in excessive silt in the water, which puts heavy load on the RO and leads to membrane clogging. The condition not only causes an increased workload on operation personnel, but also prevents RO from normal functioning. It is not uncommon that the entire pure water system must shut down.
In treating water with high Silt Density Index (SDI), most de-signers are aware that UF is the most effective pretreatment method for RO systems. However, due to factors such as higher initial cost, operator’s lack of proper skill, etc. UF is not as widely used as a pretreatment system as it should be. Through thorough study and careful evaluation, it becomes obvious that UF is the most cost effective investment in the long run. UPT personnel grasp every aspect of the design and the operation of the UF system.

The UF system we use features automatic fast flush that washes off impurities, such as silt, colloids, etc. attached to the surface of the UF membrane on timed intervals. In addition, we use UF membranes made of special material, which are less prone to clogging, chemical resistant and antibacterial, thus suitable for pretreatment systems.

Bayer Multistep Technology

Though traditional mixed-bed ion exchange resin tower can produce pure water with greater than 15MΩ-cm resistivity, it is in practice very complicated to operate and vulnerable to resin contamination, and thus requires longer regeneration and cleaning time, making the system less efficient. Furthermore, the knowledge of an operator and that of a designer can cause great variations in the system performance.
Bayer’s patented Multistep Ion Exchange System is designed to improve upon the ineffectiveness of the traditional mixed-bed technology. The system also delivers pure water with greater than 15MΩ-cm resistivity while having the benefits of consistent quality and improved regeneration rate. Though the initial investment of the system is higher than that of a mixed-bed, savings on the operation cost can be substantial in the long run. Above all, the system is environmentally friendlier.

Features and Benefits of Multistep System:
●Neutral resin preventing from clogging
●Fully automated design, reduced labor cost
●Shorter regeneration time (about 2/3 that of the mixed-bed)
●Less regenerant consumption (about 1/2 that of the mixed-bed)
●Reduced service water (about 1/2 to 2/3 that of the mixed-bed)
●No regeneration backwash, smaller footprint, increased opera-ting capacity
●Simple regeneration procedure, elimination of incomplete regeneration and thus consistent product water quality
●Longer resin service life (less workload on the top-layer resin, which can be reused in the bottom layer)

Continuous Electrodeionization Technology

CDI-LX system is a revolutionary product that uses a combination of ion exchange resins and membranes, and direct current to continuously deionize the water. It is mainly used in the pure or ultrapure water systems to continuously produce deionized ultrapure water (Approximately 18 MΩ-cm). Applications cover semiconductor, biotechnology, pharmaceutical, power generation and chemical industries. There is no need for regeneration chemicals, thus reducing or eliminating the generation of wastewater, making it the most environmentally friendly equipment in the industry.
The CDI-LX is of modular design using IONPURE’s latest patented module, which is the most advanced and reliable EDI products existing today. IONPURE is an innovator and the leader in the industry. UPT started actively promoting DCI/EDI technologies in 1995, and has earned trusts and praises from our clients, and as a result we have become a priority OEM partner of IONPURE.

Features and Benefits of CDI-LX Products:
●Lower operation cost
●No regeneration needed, continuous operation
●No brine feed, free of chlorine, improved system safety
●Modular design, high system stability, cost-effectiveness
●High operating temperature module (approximately 80℃) for hot water sanitization
●No concentrate recirculation, lower power consumption, simple operation & maintenance
●Rugged construction, high operating pressure, double o-ring design ensures leak-free operation
●No brine injection required into concentrate stream thus reduced operating cost, total recovery of concentrate
●Patented IONPURE concentrate compartment helps reduce working voltage and improve product water quality

Technology for the Removal of Low-level TOC

UV or ozone oxidization is generally used for TOC removal. For applications requiring low-level TOC such as nano or new generation semiconductor process water, either of the UV or ozone oxidization used alone yields limited results. But the combined UV and ozone treatment will be more efficient in eliminating TOC due to the conversion of ozone to free radicals in the presence of UV light.
