Water treatment and filtration


Alex Engineering & Construction provides complete technological solutions for purification and filtration of water for industry and households – drinking water, water used for technical purposes and pool water.

Foreign particles in the plumbing may cause great problems and enormous expenses. The water that we drink is mostly clean. However, the problem occurs during transport of water to your facility. A broken pipe, service pipelines and other factors enable foreign particles to enter the water pipes and consequently, your installations. That can cause many problems such as clogged valves, leaking faucets and, in extreme cases, breaking of the pipeline. The way to prevent that is to install a mechanical filter to stop the waste before it can cause any problems.

ALEX E&C offers a wide range of high quality devices used for water purification:
Mechanical filtration (30, 50, 100, 200 microns)
Sand (AFM) filtration – 0.1 – 30 microns Water softening (simplex and duplex systems)
Water demineralization (reverse osmosis)
Ultrafiltration – aeration of water (air diffusors)
UV sterilization of water
Water disinfection
Chemical dosing equipment
Measuring and regulation devices for dosing of chemicals

Relying on many years of our own experience as well as the experience of leading European producers of water treatment and filtration equipment, we have developed our own sector which deals with high efficiency and affordable technological solutions for industrial and drinking water quality improvement using the latest technologies. Water purification equipment is configured by our team, consisting of technologists, mechanical and sanitary engineers, based on the physical/chemical and bacteriological analysis of water.

In order to properly determine the dimensions of water treatment equipment we need to know a few additional parameters: hourly/daily/monthly water consumption, intended use of water (domestic, commercial, industrial, special purpose) and technical possibilities for installation of the equipment (pipe diameter, pressure, position). The use of the latest technologies is our starting point and constant development of the products which we are the representatives of makes a significant contribution to the growth of our company.



Interwoven with a net of crystal clear streams, Tara is synonymous with clean, deep green water and untouched nature. Inspired by Tara, we created water filters to bring you closer to the touch of untouched nature. Pressure filters are an integral part of any pool water filtration system. We offer our customers a complete and long-term solution that includes high-quality pressure filters. TARA filters can be used in the purification of water in swimming pools, communal plants for the purification of drinking water or for the purification of technical, process or waste water. They are suitable for use in the textile, chemical, pharmaceutical, agricultural and food industries – wherever mechanical water filtration is required and can be customized according to the specific requirements and needs of customers. We have the knowledge, capacity and experience to design and manufacture pressure filters, vessels and clarifiers for industrial water treatment plants, as well as storage tanks for various purposes. We have decided to adhere to globally recognized standards – the German standard AD – Merkblatt N1 and the BS4994 UK standard because compliance with the two standards ensures the highest product quality. Also, these two standards include all other European standards.


water treatment products

Our name says it all: we understand our mission to be to develop the best water treatment products and services anywhere. But even more: water is our mission. We ensure hygiene, safety and health in people’s day-​to-day contact with water. We continuously pursue our research to develop innovative solutions, and work to further enhance our products. We aspire to provide our customers with the highest quality water treatment systems, technologies and services while simultaneously conserving the resources of our blue planet. One of the engines for growth is innovation. A company that seeks to grow, expand and improve must further develop itself, its products and services on a continuous, pro-​active basis, and sometimes think outside the box rather than rely on conventional, tried-​and-tested ways. By growth, we also mean geographically: currently, there are more than 80 BWT subsidiaries and affiliated companies worldwide, as well as R&D departments in France, Germany, Switzerland, Austria and Russia. And we’re working on more! For us, however, further development doesn’t only mean thinking about the far distant future, but also on what’s lies directly ahead. This is why we’re working continuously to improve and optimise our existing processes and procedural workflows, as well as fine-​tuning current technologies and products to make them even better. Throughout this growth process, we remain committed to our obligation of assuming environmental, economic and social responsibility.
