High Mediums Pressure Filters - Filtration and Water Treatment

Filters with a high filling level are intended especially for treatment of surface and ground water into drinking water. They find their application also during the process of removal of undesirable substances [metals, minerals, bacteria...] from process water.

The height of the filtration mediums for filters with a high filling level is at least 1000mm and the total height of the pressure filtration vessel is higher than 2000mm.

The filtration rate of these filters is rather slow, it moves between 5 and 15m/hr, whereby it is possible to achieve a perfect removal of fine insoluble and settled substances, soluble substances, bacteria and turbidity from water …

By means of filtration through the filtration bed of pressure filters with a high filling level it is possible to remove turbidity, colloid substances, undesirable colour or odour, microbiological contamination, ammonia ions, iron, manganese from water and to reduce water acidity …

A part of the process of iron and manganese removal from water is:

• pH control, oxidisation with air, dispensing of chlorine or other oxidisation additives
• filtration with the help of deep sand or catalytic mediums
• filtration rate is 5 to 15 m/hr

• Gross pre-filtration by automatic screen filters - removal of mechanical impurities from water flowing from the waste water treatment plants
• Slow filtration through the sand bed of pressure filters with a high filling level
• Disinfection by the dosing of sodium hypochlorite and by using the UV system

The result is formed by optimum values of BSK5 and CHSK. Then it is possible to release water freely into an open water source or it can be further used e.g. for irrigation, car washing lines, street sprinkling …

• Pumping of water from the river
• Gross pre-filtration by automatic screen filters - removal of mechanical impurities, protection and extension of the lifetime of the sand bed of pressure filters, reduction of back washing frequency
• Dosing of the coagulate material
• Slow filtration through the sand bed of pressure filters with a high filling level – removal of settled substances from water
• Disinfection by the dosing of sodium hypochlorite or by using the UV system
• Water distribution into the water tower and water main system

The result of the entire process is drinking water of the highest quality.

• Gross pre-filtration by automatic screen filters - removal of mechanical impurities from water pumped from the well
• Dispensing of chemicals - flocculation
• Slow filtration through the sand bed of pressure filters with a high filling level
• Additional water treatment through pressure filters with active charcoal
• Disinfection by the dosing of sodium hypochlorite, storage tanks with water

The result of the entire process is drinking water of the highest quality.

This compact automatic unit serves for production of a small quantity of high-quality drinking water from both open and closed sources. The capacity of this compact unit oscillates, according to the size, between 20 - 150m³/day. The system is installed on the frame and is intended for a fast installation and immediate activation. It is suitable for the use in camping sites, on farms and in the places of temporary assemblies ...

• Design materials: stainless steel 304L or 316L
• Special coating and jets resistant to high temperatures [+95°C]
• Colour design according to colour shades of the RAL system

Although the filters are manufactured in a top technical and technological quality, their installation, operation and maintenance are very easy. They are intended for a continuous operation and are non-demanding in terms of both rinsing water consumption and consumption of energy.

If you require production or treatment of drinking water, removal of any organic or soluble substances from water, please contact us and we will draw up, free of charge, a proposal for the most suitable solution for you, on the basis of a raw water analysis, required filtration capacity [m³/hr] and required quality of output water.
