Water Treatment

Water preparation processes comprise a wide range of technologies and physical-chemical methods. Methods must be selected with a view to the purpose of the use of the prepared water – the preparation of potable water requires a different approach from, e.g., the preparation of cooling water, feed water for boilers, or process water..

Factors such as a growing population, decreasing supplies of surface water, and the price of potable water consumption, represent the reasons for the increasing need to optimize existing water preparation procedures with regard to their economy. For the past 20 years, membrane processes have experienced rapid development and today they are increasingly used in the water preparation sphere, where they are replacing the technologies that have been used thus far.

Our reverse osmosis systems are made precisely in accordance with the customer’s specifications. Their design enables the use of water from various sources, e.g., potable, service, wastewater, etc.
Reverse osmosis stations are employed for the preparation of demineralized water for industrial use. The reverse osmosis technology is environmentally friendly, i.e., no chemicals are required for the regeneration or neutralization of wastewater. Its advantages are low spatial demands, low operating costs, low maintenance costs, and easy operation.

Power plant chemistry is a term that includes water preparation, corrosion, fatigue, and the service life of materials under the influence of chemical admixtures in the steam circuits of conventional and nuclear power plants, steam production, and the chemical cleaning of water and steam circuits.

     Preparation of Potable and Service Water

Preparation of studies and projects for the standard or
special treatment of groundwater and surface water, incl. elimination of Fe, Mn, NH4+, NO3-, heavy metals, Rn, As, and CO2 Softening, and improving the taste and smell of potable water. Ensuring the production, deliveries, assembly, and operation of plants for the above-mentioned water treatment, incl. the application of such procedures as micro-filtration, ultra-filtration, nano-filtration, reverse osmosis, and ozonation. Hygienic protection of potable water (chlorination, ozonation, UV irradiation), and analytic and operational checks of water treatment. Refurbishment of water preparation plants; refurbishment of waterworks. Sales of water preparation plants

The refurbishment of water reservoirs, pumping stations, technological equipment, or water reservoirs
– Pumping station technology
– Installing an automatic pressure station with a
frequency  changer
– Replacement of valves, pipelines
– Biological audit of water reservoirs
– Assistance with application for grants for the refurbish
ment / construction of water reservoirs from the EU
support programmes
On the basis of the client’s requirements, we are also able to supplement the existing technology to ensure the required potable water quality (disinfection, softening, reduction the content of nitrates, iron, etc.).
On request, we will prepare the design documentation for all stages of the approval proceedings.

Helping to solve the problem of the excessive occurrence of cyanobacteria and algae in water bodies:In recent years, the quantity and concentration of phosphorus in water bodies has been increasing.
This results in the mass development of cyanobacteria and algal bloom in lakes and water bodies. The excessive multiplication of cyanobacteria, which are highly toxic organisms, impairs the biological and hygienic quality or water.
Our company is involved in solving these problems. An important factor is always the comprehensiveness of any solution. The first steps include analyses, then we suggest a solution, and in the last stage we implement particular measures to suppress the mass development of cyanobacteria.

For this technology, the physical-chemical principle of cyanobacteria multiplication suppression is used, namely the dosing of coagulant into surface water. The vessel can be used for the controlled and exact dosing of any liquid substance into reservoirs, with detailed reporting as to the application.

The vessel for separating biomass particles from the water surface is used to remove biomass from the water surface.

Pump aeration towers are mainly used to stir the water column of the lake. They mainly use the principle of the transport of oxygenated water that is beneath the surface, to layers without oxygen that are near the bottom.

Aeration towers with an aerator are mainly used to oxygenate the water column. Air is supplied to the aerator that is installed over the bottom. In the aerator, the air is mixed with water and this mixture of air and water is distributed via the aerator nozzles to the surrounding oxygen-free environment.

In this field, through the cooperation with ASIO, spol. s r.o. we can offer to our customers the preparation of expert statements, consultant services, studies and designs, audits and preparation of operating rules for:
– water management optimization,
– design of economically suitable technologies of greywater
purification,
– economic evaluations of proposed technologies of
greywater purification,
– detailed processing of operating costs,
– proposals for rational solutions, process flow diagrams,
operating parameters and modes, and
– suitability evaluations for various types of building
structures.
Applications in the following spheres: family houses, apartment houses, wellness centres, swimming pools, bath houses, office block, hotels, industrial plants, and sports centres.
