Water is a vital resource, but only 3 % of the water on our planet is fresh. Of these reserves, just 10 % can be exploited economically. It is estimated that 1.5 billion people lack access to clean drinking water and there is a water shortage in already 32 countries. Water is the most vital raw material of the 21st century. Accordingly, a secure water supply is regarded as one of the most important global objectives for the coming years.
Today, a secure drinking water supply is impossible without the use of the latest technology In many locations. Innovative technologies for the treatment of drinking water as well as water reuse are gaining in importance in all the world's regions.
VTP WATER TECHNOLOGIES has responded to this challenge with a comprehensive and highly qualified range of solutions and offers a wide spectrum of chemical, physical and biological processes for the water treatment in line with the different water sources:
- Ground water
- Surface water
- Sea and brackish water
VTP WATER TECHNOLOGIES performance meets all the stricter limits in the drinking and wastewater sectors and in many cases, future developments are also taken into account. We design and build plants of the highest standard and contribute to the prevention and removal of environmental loads through the realisation of our scientific know-how and constant process development work.
GROUND WATER TREATMENT SYSTEM:
Rising levels of groundwater pollution are confronting water utilities with increasing difficulties. The problem of nitrates and pesticides in areas of intensive agricultural activity and the contamination caused by halogenated hydrocarbons from site leachate, make the treatment of natural water reserves essential.
Moreover, apart from these manmade impurities, groundwater may also contain natural substances, which affect drinking water quality.
VTP WATER TECHNOLOGIES has developed and optimised numerous technologies especially for groundwater. We offer top processes, ranging from biological denitrification and advanced oxidation, to membrane technologies (MF, UF, NF, UO):
- Biological denitrification for nitrate removal.
- Nitrate removal using electrodialysis.
- Removal of organic impurities by use of ozone and advanced oxidation.
- Membrane filtration – Microfiltration, Ultrafiltration, Nanofiltration
- Reverse osmosis
- Removal of ammonia, iron, manganese, and arsenic
- Removal of suspended solids by means of floc-filtration
- Adsorption of pollutants on activated carbon
- Softening and demineralisation (by precipitation, ion exchange)
- Ion exchange techniques for partial and total desalination
SURFACE WATER TREATMENT SYSTEM:
Surface water is comprised by water from rivers, reservoirs and lakes, i.e. all the water resources found on the surface of the earth's landmasses.
Surface water is exposed to various natural and human influences. For this reason, it contains a diversity of dissolved or suspended materials, which are normally found in a variety of differing combinations. For this reason, multi-barrier systems are required, in order to produce high-quality drinking water and permit the problem-free use of treated water for a range of industrial applications.
Following intensive development work, in recent years VTP WATER TECHNOLOGIES has introduced numerous innovative processes for surface water treatment including filtration technology, advanced oxidation and membrane filtration.
Membrane technology is of growing importance for the removal of dissolved organic matter, micro-organisms and suspended solids, as well as drinking water softening and desalination. VTP WATER TECHNOLOGIES has successfully utilised membrane processes such as micro-, ultra- and nanofiltration and reverse osmosis for surface water treatment.
VTP WATER TECHNOLOGIES has completed numerous surface water treatment plants with differing capacities in a range of countries. During the past decade, we will design and build around 10 surface water treatment plants.
SEA WATER TREATMENT SYSTEM:(Desalination)
- Thermal desalination
- Reverse osmosis
- Electro dialysis
Approximately 97.5% of the world's available water reserves consist of seawater containing salt, which is therefore undrinkable. Many countries of the world are suffering from an acute water shortage. Accordingly, the desalination of sea- and brackish water has gained enormously in importance and is now a technically and economically recognised method of obtaining clean drinking water and fresh water for industrial operations.
VTP WATERTECHNOLOGIES has over 10 years of experience in this sector is one of the world's few companies to possess a complete range of technologies for the desalination of sea- and brackish water. Indeed, VTP WATER TECHNOLOGIES is able to offer optimised, tailor-made solutions for both the production of drinking water and industrial desalination.
- Reverse osmosis
- Thermal desalination
- Electro dialysis
- Ion exchange
VTP WATER TECHNOLOGIES has designed, installed and successfully commissioned over 10+ plants worldwide.
INDUSTRIAL WATER TREATMENT PLANTS:
Water is an important production factor. In industry water is required that corresponds with the differing needs of respective processes. The spectrum of industrial water ranges from cooling and boiler feed water in power stations and process water for a wide range of industrial uses to ultra pure water for the electronics and pharmaceutical industries.
We can supply a tailor-made solution for each specific task. VTP WATER TECHNOLOGIES offers an extensive portfolio of treatment processes for the securing of the quantitative and qualitative supply of water to industrial companies, covering 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.
- Process water
- Boiler feed water
- Service water
Industry needs water of different qualities for production purposes. The demands with regard to the standard and purity of the water range from simple, low-quality washing water, to pure boiler-feed water for steam production. The public drinking water network can be used as source of raw water, along with ground- and surface water.
VTP WATER TECHNOLGIES offers an extensive portfolio of treatment processes for the securing of the quantitative and qualitative supply of water to industrial companies. Flocculation, sedimentation, filtration, membrane filtration, full and partial desalination by softening, reverse osmosis, ion exchange and thermal desalination processes, are combined and implemented according to individual requirements.
The availability and integration of these diverse processes, not only facilitates an optimum response to specific situations, but also water recycling in closed cycles, which conserves resources.
VTP WATER TECHNOLOGIES has designed and installed plants for various industrial branches such as power generation, the chemicals, petrochemicals and pulp & paper industries. VTP WATER TECHNOLOGIES plants for process water treatment are in operation around the world.
BOILER FEED WATER
In various industrial facilities, such as those in the field of power generation or the petrochemical industry, boiler plants are often the key component in the production process. Such plants need top quality water, in order to prevent dangerous scaling.
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 composition and the required boiler feed water quality.
Typical components in VTP WATER TECHNOLOGIES boiler feed water treatment processes are:
- Systems for make-up water supplies, e.g. pre-treatment and demineralisation and silica removal (thermal or RO desalination and ion exchange)
- Systems for condensate treatment, e.g. with filtration, cation exchange and mixed bed filtration.
- System components for mechanical, thermal and chemical degasification.
VTP WATER TECHNOLOGIES has vast experience in this specific field and has equipped many industrial plants with boiler feed water treatment systems. Highly respected companies such as Siemens and Lurgi, ABB, BASF as well as national power authorities like the CEZ in the Czech Republic, or TEAS in Turkey, number among more customers.
Industrial operations need various water qualities for differing applications, e.g. process water for direct use in production, boiler feed water and treated condensate for boiler plants and service water either as a supplement in cooling towers, or for general purposes.
Service water is necessary for preparatory processing phases or industrial purposes. Typical applications include, e.g. the supply of thermal power stations and petrochemical plants with cooling water, water for fire-fighting systems and the cleaning of machinery.
During treatment, flocculation, sedimentation, filtration, membrane filtration, full and partial desalination by softening, reverse osmosis, ion exchange and thermal desalination processes can be combined or used alternately. Service water of an appropriate quality is taken from the corresponding point in the water treatment plant.
VTP WATER TECHNOLOGIES has a comprehensive range of experience with such combined plants for industrial applications.
