Basic Information

Brand	:	Waste water
Model	:	Floating unit
Operating Voltage	:	400/50
Year manufactured	:	unknow
Description	:	It is a floatation unit. That means that effluent is pumped to it from a storage/homogenisation tank. This tank normally should hold the total water consumption. In this case it is a 250m3 concrete tank which by obvious reasons is not included. Read more Sulphide oxidation also takes place in a tank out doors and is not included. The plant is as you ask set up for liming to finishing, but the two above mentioned tanks will be considered “infra structure” and have to be built on site. The original manual exist but would in any case be outdated as it has never been set up to go fully automatic, and has expanded with new sludge dewatering system (filter presses) Capacity is approx. 30-35 m3/hour. Naturally depending on quality of the water, how much solids. Tannery had a total water usage of 500-550 m3 per day and was operating the plant on 1-1,5 shifts. They had a large proportion of vegetable in their retanning which produces a lot of solids. The actual building is approx. 120 meter square. Electric installed power is about 65 kW Naturally depending on how much space you want around, all sulphide oxidation tank and homogenisation tank which are all outside. Plant is still as it was while in use. The flotation tank is in one unit approx. 8 metres long. The two chamber filter presses are approx. 5 metres. Not in the pictures is the pre screening and the compressor for the DAF System Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms tiny bubbles which adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be removed by a skimming device.[1][2][3]Dissolved air flotation is very widely used in treating the industrial wastewater effluents from oil refineries, petrochemical and chemical plants, natural gas processing plants, paper mills, general water treatment and similar industrial facilities. A very similar process known as induced gas flotation is also used for wastewater treatment. Froth flotation is commonly used in the processing of mineral ores. Read Less
