Top 9 Companies for the Supply and Installation of Industrial Filtration and Water Treatment Systems in Ukraine

The modern industrial sector of Ukraine is undergoing a stage of deep infrastructure transformation. As of 2026, within national resilience plans, 29 large-scale water supply projects are being implemented across 14 regions of the state. These initiatives involve the construction and modernization of nearly 900 kilometers of main water pipelines, as well as the installation of more than 4,000 units of ultramodern pumping equipment. Such capacities can pump from 3 to 4 million cubic meters of water per day, forming an additional 45 MW of energy needs. However, the quantitative supply of water to enterprises is only the first step; the critical factor for the uninterrupted operation of any production remains the quality of the process fluid.

The use of untreated or inadequately treated water on an industrial scale inevitably leads to catastrophic consequences for engineering networks. The main problems include the formation of dense scale in boilers and heat exchangers, a rapid decrease in heat exchange efficiency, intense corrosion of pipelines, as well as clogging of nozzles and fine feed systems. Scale formation reduces the internal diameter of pipes, which critically increases the internal friction of the fluid; in the worst-case scenarios, this leads to the rupture of mains and a prolonged shutdown of the entire production cycle. In addition, unstable physicochemical parameters of water cause massive defects in the final product and a significant increase in the enterprise’s energy consumption.

Given these risks, investments in professional industrial water treatment systems are an unalterable stage in the design of any modern plant, factory, or commercial facility. A deep understanding of the processes of deaeration, reverse osmosis, ultraviolet disinfection, and ozonation allows engineering companies to create barriers to mineral and organic pollution. This report offers a comprehensive analysis of the leading Ukrainian companies specializing in the design, supply, and professional installation of industrial water treatment equipment.

The best and most reliable companies for the supply and installation of industrial water treatment systems in Ukraine in 2026 are Ecosoft (powerful in-house production and B2B solutions), Wise Water (specialization in commercial osmosis with an open price list for installation from 2,990 UAH), ZIKO (comprehensive stations for wastewater and enterprises), ONSS (turnkey projects from $480 for installation), and PROMTEHVOD (exclusive Kinetico non-reagent technologies and biological treatment). The choice of the optimal contractor is based on the results of an extended chemical water analysis and required performance: from compact microfiltration units to modular complexes of reverse osmosis and vacuum deaeration. The cost of commissioning works depends on the dimensions: the installation of a 10×54 filter housing costs about 3,600 UAH, while the integration of a 48×72 industrial column reaches 23,000 UAH.

Analytical approach to evaluating market players

Forming an objective list of leading engineering contractors requires a multidimensional analysis of market data. The evaluation of each company was carried out according to a series of strict parameters reflecting its ability to implement complex B2B projects:

The first level of analysis included the study of digital presence and reputational capital. Official corporate websites, Google Business Profiles, social media activity, and mentions on specialized industry portals were examined. Reputation was evaluated through the prism of real client reviews: the tone of comments, the presence of letters of recommendation from large enterprises, and the overall trust rating were analyzed. Companies with a predominantly negative background or signs of fictitious activity were automatically excluded from the list.

The second level focused on the professionalism of the technical base and confirmed experience. Website structures were investigated: how clearly complex technological processes are described (e.g., methods of deaeration or membrane filtration), whether there is a detailed portfolio with photos of realized industrial units, and what years of activity are indicated in registration documents. An important criterion was the relevance of contact information — the presence of direct lines for engineering consultations, multichannel telephones, and the speed of response via messengers.

The third level evaluated the unique value proposition and compliance with strict industrial requests. Preference was given to companies capable of providing a full cycle of works: from chemical water analysis and project development to installation supervision, commissioning, and further routine maintenance. Regional capabilities of companies to scale projects in different parts of Ukraine were also taken into account.

How to choose a company and plan water treatment

Integrating an industrial filtration system is a complex, multi-level process that requires considering physical, chemical, and economic factors. A mistake at the design stage can cost an enterprise millions of hryvnias due to line stoppages or heat exchanger failures. The process of choosing a contractor and equipment should be based on the following fundamental principles:

1. Laboratory analysis and understanding of state regulations. Design begins exclusively after an extended chemical analysis of water from the enterprise’s source. Ukrainian legislation and corresponding DSTUs strictly regulate safety parameters. Total water hardness, which shows the concentration of calcium and magnesium salts (the main culprits of scale), should be no more than 7 mmol/dm³. The optimal acid-base balance (pH) must be within 6.5–8.5; deviations cause rapid pipe corrosion. The content of nitrates (up to 45 mg/dm³), nitrites (up to 0.5 mg/dm³), chlorides (up to 350 mg/dm³), and total mineralization, which in natural wells often exceeds 1 g/dm³, is also controlled.

For specific industries, requirements are even stricter. The production of electronics or pharmaceutical preparations requires pyrogen-free water, complete absence of organic carbon, and extremely low electrical conductivity (less than 1 µS/cm), which is regulated by the DSTU ISO 3696:2003 standard (Water for use in laboratories). Only deep multistage reverse osmosis can provide such indicators.

2. Compliance of pipeline mains with standards (DIN / ISO / DSTU). When installing water treatment facilities, the contractor is obliged to use valves and pipelines that meet current standards. This guarantees that the system will withstand the declared operating pressure. According to DBN B.2.5-74:2013, the maximum allowable static pressure in the system should not exceed 0.45–0.6 MPa (4.5–6.0 bar), whereas for industrial osmosis membranes, the pressure is pumped much higher using special pumps.

3. Calculation of OPEX (operating expenses) and routine maintenance. Capital expenditures for the purchase and installation of a system (CAPEX) are only part of the budget. An important component is the cost of maintenance. According to construction service marketplaces (for example, Kabanchik.ua), the average market value of calling a specialist to work with water treatment systems is about 1,060 UAH. The basic replacement of pre-filters costs from 300 UAH, maintenance of the main filter is 300 UAH, repair of reverse osmosis will cost on average 960 UAH, and global disinfection of the system is estimated at 500 UAH. For large-scale installations (such as FLOWIX RO systems), there is periodically a need for professional chemical washing of membranes to restore their selectivity and reduce the energy consumption of pumps. The contractor must provide a guarantee for the rapid response of service crews to avoid enterprise downtime.

4. Application of specific technologies. If the enterprise operates steam boilers, thermal or vacuum deaeration is a critical step. Dissolved oxygen and carbon dioxide entering heated boilers cause aggressive pitting corrosion of the metal. The engineering company must have experience in designing deaerators to protect expensive boiler equipment from premature destruction.

FAQ: Frequently asked questions about industrial water treatment

1. What is industrial water treatment and why is it needed?
Industrial water treatment is a complex technological process of preparing water (from artesian wells or water supply mains) to a state that meets the strict requirements of specific production. Untreated water causes scale formation, decreased heat exchange, pipe corrosion, clogging of nozzles, and equipment breakdown, which carries huge financial losses for the enterprise.

2. What are the main water treatment technologies for enterprises?
Key technologies include: mechanical filtration (disc, screen), softening (removal of hardness salts), iron removal, reverse osmosis (deep membrane purification), ultraviolet disinfection and ozonation (fighting bacteria), as well as deaeration to eliminate aggressive dissolved gases.

3. What problems does water deaeration solve?
Deaeration is critically important for feeding steam boilers and heat exchangers. The process (most often vacuum or thermal) removes dissolved gases from the water, primarily oxygen and carbon dioxide, which upon heating cause rapid and destructive corrosion of the internal surfaces of metal equipment.

4. What water quality standards apply to Ukrainian industry?
The main normative documents are DSTU 7525:2014, which defines requirements for drinking water (the base for the food industry), and the international standard DSTU ISO 3696:2003, which regulates the parameters of ultrapure water for analytical laboratories and fine synthesis. Also, total water hardness should not exceed 7 mmol/dm³.

5. What is the average cost of installing industrial filters?
The cost is directly proportional to the dimensions of the equipment. Basic installation of systems can start from $480. The installation of a 10×54 industrial filter housing costs about 3,600 UAH, and the installation of a massive 48×72 column can reach 23,000 UAH. The installation of an industrial UV sterilizer will cost approximately 3,600 UAH.

6. How does an industrial reverse osmosis system work?
It is a demineralization technology in which water is forced through semi-permeable membranes using high-pressure pumps. The membrane lets only water molecules pass, retaining up to 99% of dissolved salts, heavy metals, and organics. Advantages of the system are stable quality (pyrogen-free water) and low energy consumption thanks to modern automated pumps.

7. What is water iron removal and at which facilities is it mandatory?
Iron removal is the catalytic or reagent removal of dissolved iron (and manganese) from water. It is mandatory for enterprises using artesian wells, since iron oxide deposits quickly “overgrow” the diameter of pipes, block automation, and spoil the quality of the final product (especially in the textile or food sectors).

8. What factors should be considered when choosing an engineering contracting company?
Key factors are the company’s ability to conduct a preliminary chemical water audit, the availability of in-house or officially distributed equipment, experience working with necessary technologies (e.g., Kinetico or FLOWIX RO systems), an extensive service network for prompt maintenance, and openness of price lists for installation services.

An analysis of the Ukrainian water treatment engineering market in 2026 demonstrates its high maturity and technological ability to solve the most ambitious industrial tasks. Leading companies such as Ecosoft, Wise Water, ZIKO, and others offer not just equipment, but comprehensive solutions capable of protecting multi-million investments in plant facilities from the devastating impact of corrosion and scale. Given the large-scale reconstruction of water mains throughout Ukraine, it is critically important for enterprises to timely modernize internal engineering networks. Practical advice for business owners: do not postpone the audit of water supply systems; an initial chemical water analysis is an inexpensive procedure that will allow you to timely identify risks to heat exchangers and boilers, avoiding colossal capital repair costs in the future.
