ADVANCED & EASY SOLUT IONS TO EVERYWHERE

Our long term experience of UW-Tech’s in water treatment is applied in our new compact containerized Water Treatment

unit. Our system is based on Reverse Osmosis (R.O.) process which provides several benefits.

The R.O. technology is an advanced high effi-ciency rate water treatment process and repre-sents the finest level of liquid filtration available today. Whilst ordinary filtration systems use a screen to remove particles from a water stream, Reverse Osmosis utilizes a membrane to re-move dissolved minerals. More specifically, R.O. is a membrane process for desalting saline wa-ter by the application of hydrostatic pressure to drive the feed water through a semi permeable membrane while a major portion of its impuri-ty content remains behind and is discharged as waste.

The largest and most important application of reverse osmosis is the production of pure wa-ter from seawater and brackish water; seawa-

a high pressure is exerted on the high concen-tration side of the membrane, usually 2–17 bar (30–250 psi) for fresh and brackish water, and 40–82 bar (600–1200 psi) for seawater, which has around 27 bar (390 psi) natural osmotic pressure that must be overcome.

We produce high quality Containerized or Skid mounted Reverse Osmosis Systems and we support their operation through our own inter-national technical assistance support service teams. This way we guarantee that our plants wherever they may be installed will run efficient-ly at all times.Our company also provides services of its expert engineering team on the design, manufacture, operation and maintenance of reverse osmosis systems. Laboratory facilities are also available to serve our clients with the control of the prod-uct water quality as well as complete ionic and bacteriological analyses of the water to be treat-ed.

ter or brackish water is pressur-ized against one surface of the membrane, causing transport of salt-depleted water across the membrane and exit of low salt water from the low-pressure side.

The membranes used for reverse osmosis have a dense layer in the polymer matrix – either the skin of an asymmetric membrane or an interfacially polymerized lay-er within a thin-film-composite membrane – where the sepa-ration occurs. In most cases, the membrane is designed to allow only water to pass through this dense layer, while preventing the passage of solutes (such as salt ions). This process requires that

Key Features and Benefits

• A number of benefits derive from the use of Containerized Reverse Osmosis Sys-tems in the UW-Tech RO-Plants:

• Very Small Foot-Print Area • Suitable for sea and brackish water (de-

pend on the applications)• Friendly to the environment, as they do

not produce or use any harmful chemicals during the process

• Production of purified water, colour free, without minerals and other contaminants that cause unpleasant water taste

• Very Compact design and robust opera-tion

• Fully automatic operation with remote monitoring is possible (Minimum Attend-ance)

• Low energy requirements and low running cost

• Excellent Treatment Efficiency and Effluent Quality

• Easy transportation, fast installation and quick start up

Appl ications

Because of its efficiency, the Reverse Osmosis technology can be used for Sea and Brackish water as well as for both domestic water (e.g. Municipalities, ho-tels, house complexes, camps, tertiary Wastewater Treatment, raw water pre-treatment, etc) and Industrial wastewa-ter (food & drink industry, process water, etc for details please contact us for con-sultation).

The new UW-Tech’s Containerized R .O . Treatment Unit

UW-Tech provides a wide range of con-tainerized R.O. treatment units (UW-

BOX-RO) ranging from 24m3/d up to 1,000m3/d (depending of the type). This unit is the main treatment part of an integrated Water Treatment Plant (WTP) with Reverse Osmosis.There are two main models; the Model called UW-BOX-RO/BW which is for brackish water desalination, with recovery rate from 60 up to 80% and the Model called UW-BOX-RO/SW for sea water desalination, with recovery rate from 25 up to 42%. All models can be transported by standard road-trucks or shipped inside ISO container in order to reach even the most distant and remote part of the world. This fact makes our Treatment Units the easiest and fastest way to implement a Wa-ter Treatment Plant at any terrain and under any condition. Furthermore, can be equipped with Anti-frost pack (includes frost protection, heated engine-room, and insulated tanks). Standard in all models, the engine-room includes lockable doors for security reasons. For bigger models an additional machine-room maybe required (prefabricated or not) in order to install additional equipment, electrical switch board (MCC) and also to accommodate a small office for the operator and or a storage area.
