Water is our element.

Water is our element.

Today, over a billion people around the world still

have no access to clean drinking water and even in

the industrialised nations, water as source of nutri-

tion is becoming an increasingly precious item. The

reasons for this development are not only climate-

related, but also due to environmental problems

and shrinking ground water reserves. Accordingly,

water treatment and wastewater purification, as

well as new technologies for water reuse and recyc-

ling, are of growing significance gobally.

WABAG has dedicated itself to taking these chal-

lenges with a range of problem solutions, which is

both comprehensive and highly advanced. With

our innovative technologies and services we make

a sizeable contribution to the provision of secure

water supply and wastewater treatment in both

the municipal and industrial sectors. The know-how

that we put into practice is based on more than

80 years of experience with water as an element.

Indeed, our trademark is a profound understanding

of everything relating to H2O.

The scope of the services that we can offer extends

from consulting and planning, financing and instal-

lation, to the operational management of plants

and systems. For our customers this means all the

advantages of tailor-made solutions provided on a

one-stop shopping basis.

Guaranteeing top quality drinking water.

In many locations, a secure drinking water supply

in the desired quantity and quality is impossible

without the use of the latest technology. Specific

technologies are employed in line with the source of

the water and the extent of its pollution.

WABAG has established itself as an ideal partner for

this communal challenge with an extensive selection

of chemical, physical and biological processes for the

treatment of surface and ground water. Our leading

technological competence is underpinned by a high

degree of process know-how and a profound under-

standing of customer needs. We engineer complete

plants, which guarantee safe adherence to the

required parameters, are designed to accommodate

future developments and are characterised by high

levels of technical reliability.

New sustainable solutions

WABAG is pushing ahead with the development and

use of technologies that conserve resources by me-

ans of modern concepts for energy recovery, which

employ small-scale hydropower plants combined

with drinking water treatment, and efficient back-

wash water recycling using membranes.

The company has also evolved advanced processes

for the safe removal of specific micro-pollutants from

drinking water, which utilise increased oxidation

(ADOX®) and oxidation processes in combination

with ceramic membranes (CERAMOPUR®).

Wenzhou WTP, China (100,000 m3/d) Bouira WTP, Algeria (74,000 m3/d)

Surface water

As a rule, multi-stage treatment processes are re-

quired to make certain that drinking water obtained

from surface sources is suitable for human consump-

tion at all times and does not cause any problems

with regard to storage and network distribution.

We have complete mastery of these multi-barrier

systems, which derives from the experience gained

during innumerable projects. Optimum solutions

using conventional processes and in combination

with advanced technologies such as membrane

filtration, guarantee high levels of flexibility and first

class water quality.

Groundwater

The quality of ground and spring water is increa-

singly subject to the negative influences of anthro-

pogenic substances, agricultural pollution and the

growing presence of chlorinated hydrocarbons.

WABAG has developed and optimised technolo-

gies, which are specifically designed for ground wa-

ter treatment. We offer top processes, ranging from

biological denitrification (BIODEN®) and advanced

oxidation (ADOX®), to membrane technologies (MF,

UF, NF, RO, EDR).

Municipal wastewater treatment

Technological progress is currently expanding the

possibilities offered by traditional environmental

protection. In the municipal wastewater sector, the

ecological focus is on water protection and wastewater

reuse, which adds up to a need for the highest possible

degree of wastewater purification.

WABAG provides complete, state-of-the-art plants for

just this purpose. We offer the best possible individual

solutions for every requirement, from carbon to

nutrient removal. As key technologies, we employ one-

and two-stage activated sludge processes, biofiltration

(BIOPUR®), moving bed biology (FLUOPUR®) and

membrane bioreactors (MARAPUR®).

Conventional processes with one- or two-stage

activated sludge systems, which include our two-

stage Hybrid™ process and SBR technology, are

used as standard solutions for average to high

cleaning requirements. Biofiltration is employed as an

alternative or supplement, whereby this has proved

to be especially advantageous where space is at a

premium and stringent requirements exist with regard

to integration into the surroundings. This in-house

developed fixed bed technology also impresses

through maximum process stability and efficiency.

The advanced MARAPUR® process, which has been

employed successfully in numerous plants, is based

on a combination of modern membrane filtration

technology (ultrafiltration) with the proven activated

sludge process. MARAPUR® stands out due to a

combination of enormous cleaning capacity and

comparatively low operating costs. Due to an outflow

that is solid-free and contains low levels of bacteria and

microbes, the process makes water reuse possible even

in the case of stringent requirements.

Sludge Treatment & Energy Recovery

For WABAG, sludge treatment is an integral part

of efficient wastewater treatment. In addition, the

anaerobic stabilisation of sewage sludge can secure an

ecologically and economically advantageous supply of

energy through the use of biogas. Large wastewater

treatment plants are thus able to cover up to 100 per

cent of their power needs.

WABAG has developed its innovative BIOZONE-AD®

process with an eye to improving the efficiency of

sewage sludge stabilisation.

Boiler feed water and condensate treatment

Boiler feed water is obtained from a wide range of raw

water sources. The related treatment processes are

tailor-made to match the respective raw water compo-

sition and the required boiler feed water quality.

The major processes involved consist of make-up water

treatment (e.g. with the process steps pre-treatment

and demineralisation with silica removal), condensate

polishing (e.g. with the process steps filtration, cation

exchange and mixed bed filtration), thermal and che-

mical degassing.

In industry water is required that corresponds with the

differing needs of respective processes (power gene-

ration, cooling, etc.). Therefore, a secure water supply

in terms of both quantity and quality is of enormous

importance to industrial enterprises. Technically opti-

mised, cost-effective water management systems make

an important contribution to successful, long-term

economic strategy.

WABAG supplies the correct individual concepts and

solutions for this purpose. With our compre hensive

competence portfolio, we cover virtually every need

from conventional processes to high-performance

systems (e.g. membrane processes). We attach special

value to reliable, low-maintenance systems that offer

high economy.

Meeting the highest environmental standards.

Industrial wastewater contains a diversity of impurities

and therefore for this reason alone, its treatment cons-

titutes a special task. In addition, effluent standards are

constantly being tightened up. Therefore, in practical

terms the treatment of industrial wastewater demands

an extensive knowledge of process technologies and

their economic combination.

Due to the experience gathered during numerous

projects, our engineers know how to fulfil customer

requirements and mandatory stipulations in full.The aim

is to achieve a perfect combination of efficiency and

economy. Naturally, this not only involves a focus on

investment expenditure, but also the minimisation of

running costs during the plant life cycle.

Innovative and flexible

In the case of biological, anaerobic wastewater treat-

ment we employ conventional processes and space-

saving, high-performance reactors. We have completed

a large number of large-scale plants on the basis of

the world’s most frequently used UASB process. Other

systems are also utilised in accordance with the charac-

teristics of the wastewater, e.g. the activated sludge

process or our high-performance BIOPUR® system for

less polluted water. In the case of maximum cleaning

requirements (e.g. water reuse and recycling) we em-

ploy membrane processes with submerged or external

membranes, and if required, cleaning phases such as

reverse osmosis and ion exchange that go even further.

Our team has designed and implemented waste water

treatment plants for customers from a variety of indus-

trial branches, including aerobic and aero bic/anaerobic

plants for the food industry, membrane bioreactor

systems (MARAPUR®) for the chemical industry and

wastewater reuse schemes for diverse branches.

For many years, WABAG has enjoyed an excellent

reputation as a reliable partner for the supply of

complete solutions in the desalination technology

sector. We have planned, installed and successfully

handed over more than 100 plants. An additional

customer advantage derives from the fact that we

are one of the few companies worldwide, which of-

fers the complete range of desalination technologies

(thermal processes, reverse osmosis).

Desalination by Reverse Osmosis, Al Wasia, Saudi Arabia (168,000 m3/d)

Saving energy and costs

Desalination plants separate sea and brackish water

into two flows consisting of a freshwater stream

(condensate in thermal processes, permeate in reverse

osmosis) and a stream with a high salt concentration

(brine or concentrate). Every desalination technology

requires energy for this separation process, which is

supplied to the system by thermal or mechanical me-

ans. Our com prehensive know-how ensures maximum

energy efficiency and hence economy in this regard.

MED — XXL

In WABAG’s newly developed XXL™-MED systems,

which have capacities of up to 45,000 m3/d and line, all

the preheaters are enclosed in an extremely compact

manner. This design not only prevents heat losses, but

also guarantees optimised operations.

Optimum pre-treatment

As a systems supplier, we provide the required in- and

outflow structures and place a special emphasis on

efficient pre-treatment. In this connection, apart from

conventional filtration technologies, highly effective

micro- and ultrafiltration systems are employed.

Sustainability through water reuse.

In view of the limited availability of water and the ne-

cessity of preserving existing resources, the use of wa-

ter recycling concepts within the scope of sustainable

water management strategies is of enormous impor-

tance. Water recycling increases availability to private,

commercial, agricultural and industrial consumers and

also enhances the security of supply. Therefore, it is of

special significance in arid and semi-arid regions.

In recent years, WABAG has carried out a series of

projects for water reuse and recycling for both munici-

pal and industrial purposes. In the industrial sector, we

have planned and completed wastewater reclamation

plants to the complete satisfaction of customers in the

petrochemical and steel industries, textile and chemi-

cal industries as well as for thermal power plants. In

addition, we have also realised the world’s only direct

potable reuse plant for the conversion of wastewater

into drinking water in Windhoek/Namibia, an achieve-

ment of which we are especially proud.

Systematic efforts in the name of progress.

We believe in the power of innovation and invest

in technologies that point the way to the future.

As a progressive company, we constantly make every

effort to develop and implement inventive solutions

to the benefit of our customers. To this end, we carry

out a great deal of R&D, whereby the current emphasis

is on the areas of membrane technology, the removal

of micro-pollutants, energy-optimised processes and

advanced pre-treatment techniques.

If some twenty years ago, membrane filtration proces-

ses were still regarded as a technology of the future,

we have already established them as a state-of-the-art

separation method. To date WABAG has completed

over 100 membrane filtration plants for the treat-

ment of fresh water (UF, MF, NF, RO) and wastewater

(MARAPUR®).

On the basis of this experience, the focus at present

is on the development of processes using optimised

membranes, which above all are characterised by

low life cycle costs. In this connection, ceramic

membranes are being used for the newly developed

CERAMOZONE® and CERAMPUR® processes.

Another important task is the safe removal of micro-

pollutants from pre-treated, municipal wastewater

and contaminated groundwater. Outstanding test

results have been achieved with new processes em-

ploying ozone and activated carbon (CARBOPUR®,

PACOPUR®).

One highlight of WABAG’s R&D activities is provided

by the development of MICROPUR®, a new technology

for advanced, mechanical pre-treatment. When this fine

sieving is employed upstream of a membrane bioreac-

tor (MICROPUR-MBR®), the related technology gua-

rantees secure and stable system operation. Moreover,

through its use for pre-treatment prior to a conventi-

onal activated sludge process (MICROPUR-CAS®), the

required activated tank volume is reduced significantly,

which results in lower investment costs. Following

successful large-scale testing, the first system is to be

installed at the Andermatt WWTP in Switzerland.
