Delivering Cost-Effective, Custom Water Treatment Solutions Across the Globe Drinking Water Treatmen
We are committed to ensuring safe, dependable, and affordable drinking water, supported by decades of hands-on experience at hundreds of water treatment facilities around the world. We pay particular attention to capital and operating cost-effectiveness and environmental impact. Depending on its end use, water from wells, rivers, lakes, and other sources requires a variety of purification processes, which can include the following:
- Clarification and purification
- Softening and hardness treatment
- Specific treatments (removal of arsenic, uranium, nitrates, endocrine disruptors, total organic carbon, etc.)
- Sludge treatment
- Water treatment chemicals
- Mobile water treatment
All the plants and project solutions proposed by TWA are fully automated and can be controlled by local or remote-control systems.

Biological treatments use particular families of nonpathogenic microorganisms in the abatement of methane, ammonia, iron, and manganese in the water, using oxygen instead of chlorine or other chemical oxidizing reagents. Biological processes have zero environmental impact and low operating costs and do not produce harmful byproducts such as THMs (trihalomethanes).
The traditional treatment uses chlorine-based oxidizers, followed by sand filtration. This process, however, can lead to the formation of carcinogenic chlorine derivatives. In order to separate these substances, costly activated carbon filtering systems must be applied. Biological potabilization, on the other hand, does not produce any undesired substances and is a much simpler treatment. We have provided this solution to hundreds to our customers
Potabilization With Arsenic Removal
New arsenic limits in drinking water are set to 10 μg/l. Much of the well water in the world has arsenic concentrations well above this limit, and therefore must be treated. TWA proposes an innovative selective resin process, which, unlike the methods proposed by our competitors, has the advantage of being regenerable. This results in very high abatement performance and much lower operating cost than traditional arsenic removal methods.
Industrial Water and Demineralization with Ionic Exchange Resins
TWA has more than 15 years of experience in developing solutions to produce highly dependable, fit-for-purpose industrial water. These include resin demineralization solutions for industrial applications. TWA has acquired great expertise and experience in the construction of highly dependable demineralization plants, which are designed to operate for 24 hours a day, 365 days a year, without unscheduled stops.
