BAUER WATER 3

... is one of the four elements, and theone most closely linked to the spirit oflife itself and the enjoyment of it. Theassociations it evokes extend from acool drink, through playing games atthe water's edge, to swimming in alake or the ocean ... emotional mo-ments embodying pure nature and thejoys of life. So the simple word 'water'is linked to a range of emotions andactivities, from enthusiastic enjoymentof the world to the cold fact of thechemical formula H2O.In a political, social and economiccontext, issues relating to water turnto more objective and mundane con-cerns. Are we taking sufficient care to preserve what is the most valuableand vital of resources – and the verybasis of human life? One might thinkthat the some 1.4 billion cubic kilo-metres of water on Earth should beenough ... But 97 percent of it is seawater – that is, salt water – and so not fit for human consumption withoutprior treatment. Of the remaining threepercent of our fresh water resources,much of it is enclosed in ice, either atthe North or South Pole or in glaciers.

Just 0.6 percent of all the water onEarth is available directly as freshwater, and even most of that has to besubjected to costly and complex treat-ment before it can be used as drinkingwater.And water consumption varies widelyaround the world. Each person in Germany uses an average of about 125litres of drinking water per day. Somecomparative figures are: France 156litres, Italy 213 litres, Switzerland 237litres, USA 300 litres, and the UnitedArab Emirates as much as 500 litres.Increasing industrialization and tech-nology has impacted substantially onwater as a resource, placing majorstrains on this vital natural element ininnumerable different ways. In recentdecades awareness of the need toconserve and use water more carefullyhas grown significantly. Research anddevelopment has come up with newmethods of treating and purifyingwater. Innovative technology is avail-able to treat water. This technologyincludes systems from BAUER WaterGmbH (BWS).

BAUER Water -Around the Globe

BAUER WATER4

Bauer Water is a member of the BAUER Group, based inSchrobenhausen in southern

Germany. The third and most recentGroup segment, named Resources,was established in 2007, and is focu-sed on a number of key fields whichare of vital importance to all our futu-res: water, the environment, mineralresources and energy. Bauer Water is part of the BAUER Group's Re-sources segment.

The two other segments – Construc-tion and Equipment – represent theBAUER Group's traditional operationsin specialist foundation engineeringand machinery manufacturing. Inthose segments, too, water is a per-manent concern: whether in control-ling groundwater when installingfoundations, or in the manufacture ofdrilling rigs to sink wells. In establish-ing Bauer Water, we have concen-trated our years of experience and

expertise in the planning, construc-tion and operation of water purifica-tion systems in one unit. The globalpresence of Bauer companies, withover 100 subsidiaries and branchoffices in some 70 countries, pro-vides Bauer Water with the organiza-tional backing to operate on everycontinent. Wherever Bauer Water isrunning a project, the project teamcan utilize the existing local Bauerinfrastructure.

C lean drinking water is a funda-mental aspect of hygiene, andis essential to healthy living.

However, clean drinking water is inshort supply – or indeed virtually unavailable – in many of the world'scountries. In the industrialized nations,too, the general environmental debateof recent decades has focused moreand more on issues linked to water, including an increasing scepticism inrelation to the chemicals contained in drinking water.Based on its long-standing experienceand extensive know-how, and employ-ing innovative process techniques,Bauer Water has committed itself tosafeguarding public access to freshwater at the highest level. The portfo-lio extends from compact treatmentplants for emerging countries – tocope with the new burdens they face

arising from extensive agricultural use – and for disaster relief missionsthrough to turnkey drinking waterworks for local communities. Along-side standardized products, BauerWater offers custom solutions adapt-ed to specific requirements. At theheart of many treatment plants, featur-ing in a wide variety of different proj-ects, is membrane technology. Theplants are modular in design, and canbe supplied in a variety of size options.

One example of this technology isultrafiltration, involving membraneswith a pore diameter of 20 nanometres.This scale is most easily illustrated bya comparison: if an ultrafiltration porehad a diameter of one millimetre, thediameter of a human hair would befive metres! Aiming to provide its cus-tomers with a partner in their searchfor sustainable and economical water

concepts, the company offers a package of solutions all from a singlesource – from extraction of water re-sources through to recycling. BauerWater's in-house plant manufacturingoperation processes plastic, stainlesssteel and untreated steel, as well asassembling the complete control sys-tems. Dedicated installer teams carryout the installation.

P rocess water must meet differentquality criteria depending on thespecific industrial application

concerned. Low electrical conductivity,zero oxygen content and softness aresome characteristics of process water.As the process water required is usu-ally obtained from groundwater ormains water, it must be treated appro-priately before being fed into boilers,used for cooling, turned into ultra-purewater or used in the manufacture ofproducts. Employing a range of chem-ical/physical, biological and technicalprocesses, Bauer Water is able tomeet any customer requirements withtailored solutions, thereby also help-ing to cut the actual consumption ofprocess water. Bauer Water offers itsindustrial customers a package whichencompasses consulting, engineeringand service, through to financing. Aparticular strength of Bauer Water isits in-house plant manufacturing oper-ation. Every plant is produced to spec-ification, installed and monitored by

the manufacturer through to the com-missioning stage. The company com-mits major efforts and financial re-

sources to research and development,and is continually coming up with newinnovations.

Industrial Waste Water

BAUER WATER10

W ater needed to operateindustrial plants cannot besimply extracted from clean

sources, polluted by processing andthen disposed of in sewage plants.This method is too expensive, and is the wrong approach in ecologicalterms – a fact long overlooked duringthe era of industrialization.Over recent decades, however, arange of processes have been devel-oped to recover and re-use processwater. Many industrial plants now re-cycle the water they need to run; the"closed circuit" in relation to water isstate of the art. The wide variety ofprocesses employed in the variousindustrial fields also means that differ-ent types of waste water, with specificpollutant contents, are produced. Usu-

ally this water has to be pre-treatedbefore being allowed to enter publictreatment plants, or it is definitivelytreated before being routed into anoutfall. Ideally, process water can bere-treated and returned to the produc-tion operation. In some cases it is alsopossible to extract raw materials fromthe waste water, such as from fermen-tation residues and production waste.Decontamination of polluted water bynaturally occurring radioactive materi-al (NORM) is an integral part of the

Bauer Water portfolio, as is the deacti-vation of waste water in the pharma-ceutical industry and the sterilizationof waste water from research institutes,hospitals, etc.With its PURE reed-bed treatmentplant, Bauer Water offers an opera-

tionally safe biological method for thedistributed purification of waste water.The success of this low-maintenance,stable ecological process technique isbased on the harmonious interactionbetween the plants, the filter graveland micro-organisms.

Produced Water

BAUER WATER12

P roduced water refers to waterproduced in the oil and gas in-dustry in the course of extraction

operations. Produced water containsimpurities due to hydrocarbons andmineral substances, as well as heavymetals too in some cases, which occurin oil and gas reservoirs. Producedwater is industrial waste – and in partalso a recyclable raw material – whichhas to be treated and cleaned beforebeing disposed of or re-used.Bauer Water has set itself the goal ofbecoming a leading vendor of customcomplete solutions which are advancedin design, fit for the future, sustainableand economical. Filtration, centrifuga-tion, flotation and biological processesare the technologies it is employing tothis end. As a partner to the oil and gasindustry, Bauer Water offers a range ofpackages including complete DBOOT(Design, Build, Operate, Own andTransfer) solutions. The deployment of

all available technologies enables substantial oil content to be extractedfrom the contaminated water and re-covered on behalf of the customer.Moreover, all processes are designedto further conserve valuable resourcesby saving energy. A project unmatchedanywhere in the world is Bauer NimrOman, an enormous reed-bed treat-ment plant constructed by BauerWater on a 1.8 by 3.3 kilometre site inthe desert of Oman for the treatmentof waste water from oil extraction. Theproject is an exemplary model of anecological/biological produced water

process. By employing this technique,Oman is adopting an eco-friendlyapproach to the processing of its oilresources. The biological treatmentplant is located close to the country'smost productive oil field. The prepara-tory works involved extensive earthmovement and the cultivation of thou-sands of reeds. Stepped treatmentbasins provide the plant with a natural

gradient. The contaminated water iscascaded through the basins and issubjected to biological purification.Residues produced include salt due to evaporation, which can in turn bereused for industrial purposes. Themarketing of this salt is a key elementof the project's financing. Bauer Waterhas also contracted to operate theplant for a period of 20 years.
