The water that is supplied by public companies (or private sources) can never be cleaner then the polluted environment we are living in. We can recycle the water with preliminary filtration or ultra-filtration, ion exchange and reverse osmosis, depending on economical justification and ecological reasons.


Projects for preparation and purification of the water are based on up-to-date concepts implementing the latest technological findings. They are energetically optimal, reliable and user friendly.  All processes are monitored at the central control of the factory or on the Ethernet (omrežje), so all important information can be reached from anywhere.
For better understanding of water purifying process, we present the next example:


An example of complete water preparation for use in production of starch and syrups – 2007


The source of raw water is drinking water from the system and water from wells.
In the incoming raw water forbidden components are present and we eliminate them in several stages of water preparation.


- classical filtration - anthracite filters for removing impurities,
- deferisation, demanganisation, elimination of arsenic,
- countercurrent softening for  intermediate needs of production with final UV disinfection,
- ultrafiltration,
- reverse osmosis.


In the intermediate stage the product is soft water and in the final stage demi water with 10 μS/cm conductivity. It is used for production and for making steam in low pressure steam boilers. For reducing conductivity under 0,1 μS/cm
a membrane degasser and electrodeionisation is built in. This water is used for steam turbines in electrical energy production.


The ultrafiltration device is cyclically washed with chemical additives - acid, lixivium + disinfectant, so batch neutralization of waste waters is built in.


In continuation you will find the description of the block diagram which represents technological process and capacities.


Technological/technical data:
permeator with conductivity under 0,1 μS/cm - 50 m3/h
permeator with conductivity under 10,0 μS/cm - 25 m3/h
softened water with total hardness under 0,5 odH - 40 m3/h
electrical power of the first stage equal to 170 kW


Approximate utilization rate of the devices - quantity of waste waters:
sand filtration: under 90%
catalyst - filter: under 99%
softening device - countercurrent on raw water: under 97.5%
ultrafiltration: under 96%
reverse osmosis under 75%
EDI electrodeionisation: under 97%


Media consumption:
- Natrium Chloride - in tablets 153 kg/reg
Other chemicals are periodical in disinfection, cleaning Uf and RO membranes, pH correction. They are minimal and do not influence the operating cost of the plant significantly.
The process is monitored and operated centrally, therefore there is no need for a constantly present operator.


Equipment and materials we use for this technology:
GFK- polyester pressure vessels for filters
- PVC pipe installations, AISI 316 stainless steel for reverse osmosis, pre-filters, etc.
- stainless valves with pneumatic drive
- magnetic induction flowmeter
- continuous measurements of pressure, conductivity, pH, Rx, turbidity, etc.
- the pumps are stainless, with frequency control
- membrane modules on UF are polysulfonic with permeability of 0,02 μm
- intermediate reservoirs - polypropylene


Conclusion
Projects for preparation and purification of water are based on up-to-date concepts implementing the latest technological findings. They are energetically optimal, reliable and user friendly.  All processes are monitored at the central control of the factory or on the Ethernet, so all important information can be reached from anywhere.
