The equipment is appropriate especially for wastewater from meat processing plants, rendering plants, starch factories, poultry farms, canneries and for technological waters from paper mills and petrochemical industries. The flotation equipment is successfully used as the primary cleaning before sand filtration at the water treatment plants and for very fine treatment of technological water. Technical description: Flotation equipment SUPRAFLOT LC works in a cylindrical tank where a static lamella grid is placed. The lamellas restrict the water movement within the tank. The collecting arms radially project from the central column. The collecting arms rotate between the bottom and the lower edge of the lamellas and they have a double function. The front part (in the sense of rotation) collects the clarified water from the tank into the outlet section. The raw water is distributed from the rear part of the arms (in the sense of rotation). The jets for distribution of the pressure water are placed near to the raw water inlet. The impurities collected on the water level are removed and transported by a special collecting mechanism. The raw water inlet piping is at the bottom of the tank. The unit drive is equipped by a frequency converter to set optimally the arms velocity. An inductive flowmeter with a digital indication is used to measure the flow. Parameters: Diameter from 1,2 m to 14 m, flows from 5 to 1500 m3.hod-1 . Materials : Stainless steel, plastics. Scope of supply: Supraflot LC, air dissolving tube with a pump and compressor, electrical control box, chemicals dosage unit. We provide with chemical analyses and tests of wastewater flotation and pilot tests at the clients plant.

The equipment is appropriate especially for wastewater from meat processing plants, rendering plants, starch factories, poultry farms, canneries and for technological waters from paper mills and petrochemical industries. The flotation equipment is successfully used as the primary cleaning before sand filtration at the water treatment plants and for very fine treatment of technological water. Technical description: Flotation equipment MAXIFLOT LC works in a rectangular tank where a static lamella grid is placed. The lamellas restrict the water movement within the tank. The raw water inlet into the equipment is through a inlet pipe, which is mouthed to the bottom part of the tank. The raw water inlets the chamber of calming object, where from it flows into the tank. The jets for pressurised water distribution are placed near to the raw water inlet. The process of flotation is carried out during the water flow from the inlet object towards the outlet object. The impurities collected on the water level are removed and transported by a special collecting mechanism into a through placed along the tank and consequently to a next treatment. An inductive flowmeter with a digital indication is used to measure the flow. Parameters : Flows from 5 to 144 m3.hod-1 Materials: Stainless steel and plastics.

The filters are appropriate for filtration of cooling water of compressor plants, condensers of power plants and other technological plants. Technical description: Pressure filter FILTROMAX TF is fitted in the delivery pipes behind a pump. The water inlets the filter in the sieve axes, goes through the sieve and by the filter shell is directed to the outlet pipe. The impurities are caught on the inner part of the sieve. The level of sieve clogging is recorded by two pressure sensors in the inlet and outlet pipes and if the pressure value exceeds the set value of pressure difference, the shaft drive is started and the sucking pipe valve is opened. The impurities caught on the filter sieve are continually sucked away by the sucking hoods. During the cleaning period the filter sieve is washed by the filtered water – the water streams back through the sieve into the sucking hood and the discharge pipe. After the pressure difference drops below a set value then the wiping and sucking of the sieve is stopped. Parameters: Flow from 50 l. s-1 to 10 000 l. s-1, filter sieve openings from 1mm to 15 mm, in the straight or elbow version. Materials: The filter shell is made from carbon steel, sucking equipment, sieve, shaft and shaft bearings from stainless steel.

The filters are appropriate for filtration of cooling water of compressor plants, condensers of power plants, paper mill plants and for filtration before sand filters. Technical description: Pressure microsieve filter FILTROMAX TMF is fitted in the delivery pipes behind a pump. The water inlets the filter in the sieve axes, goes through the sieve and by the filter shell is directed to the outlet pipe situated perpendicularly to the filter axes. A stainless steel cylindrical sieve consists of two parts – a cylindrical cage and the microsieve. The level of sieve clogging is recorded by two pressure sensors in the inlet and outlet pipes and if the pressure value exceeds the set value of pressure difference, the shaft drive is started and the sucking pipe valve is opened. The impurities caught on the filter sieve are continually sucked away by the sucking hoods. During the cleaning period the filter sieve is washed by the filtered water – the water streams back through the sieve into the sucking hood and the discharge pipe.

The rake head is a part of the truck. The truck bears reducer and lifting mechanism of the rake. The lifting mechanism enables all movements of the rake during wiping of the screenings from the screen bars and from the channel bottom, the lifting of the rake during the movement of the rake into the lower position and discharge of the screenings from the rake. The truck moves only above the water level and only the rake is in contact with water. Parameters : Channel width from 500 mm to 2000 mm, channel depth to 10 m, clear space between bars 4 mm - 100 mm. Materials : Stainless steel. Scope of supply : Screen, electrical control box, anchor bolts and support for anchoring of the screen. Screening press and discharge container on request.

It is appropriate for wastewater treatment plants, where it is placed into the enter object of the mechanical pretreatment. Technical description: The wastewater inlets the grit chamber through the inner calming cylinder. Heavy particles, especially sand, sediment and the cleaned water overflows the upper edge of the chamber to the outlet channel. Sediment sand is occasionally pumped by air-lift pump after whirling of the sediments by pressurised air. Parameters: Diameters 0,8 m, 1,0 m, 1,2 m, 1,5 m a 1,7 m, maximum flows 19 l.s-1, 33 l.s-1, 50 l.s-1, 78 l.s-1 a 106 l.s-1. Materials: Stainless steel, carbon steel. Scope of supply: Air lift pump DN 100, pressurised air piping with fittings, delivery piping with fittings, grips and consoles, food bridge with handrail, on request a roof.

It is appropriate for wastewater treatment plants, where it is placed into the enter object of the mechanical pretreatment. Technical description: The wastewater inlets the grit chamber through a channel tangentially placed to the chamber and heavy particles, especially sand, sediment due to the radial acceleration. Sediment sand is occasionally pumped by air-lift pump after whirling the sediments by pressurised air. Parameters: Diameters 3,0 m, 3,6 m, 4,2 m, 4,8 m, 5,4 m and 6,0 m, maximum flows 112 l.s-1 , 215 l.s-1, 265 l.s-1, 320 l.s-1, 510 l.s-1 and 560 l.s-1. Materials: Stainless steel, carbon steel. Scope of supply: Air lift pump DN 100, pressurised air piping with fittings, delivery piping with fittings, grips and consoles, food bridge with handrail, on request a roof.
