Processing of sea water for swimming pool, bathing pool and fish farming pool, comprises contacting sea water with organisms in biotope zone and periodically flowing water through porous substrate in bottom filter zone

摘要

The processing of sea water for swimming pool, bathing pool and fish farming pool, includes contacting sea water with organisms in biotope zone (30) and periodically flowing water through porous substrate bottom filter zone (50). The organisms used in the process are macro algae and/or shell residues, sponges and/or red algae, blister seaweed, sea salad, intestine seaweed, knot seaweed and/or cartilage seaweed, shells, mussels and/or oysters. The filter basins are fixed to carrier elements (32, 33) that allow a flow region of the water to flow perpendicular to the filter zone. The processing of sea water for swimming pool, bathing pool and fish farming pool, includes contacting sea water with organisms in biotope zone (30) and periodically flowing water through porous substrate bottom filter zone (50). The organisms used in the process are macro algae and/or shell residues, sponges and/or red algae, blister seaweed, sea salad, intestine seaweed, knot seaweed and/or cartilage seaweed, shells, mussels and/or oysters. The filter basins are fixed to carrier elements (32, 33) that allow a flow region of the water to flow perpendicular to the filter zone. The water is periodically fed into each bottom filter basin, in which filling up of the water to first level of basin and discharging the water upto a given second level, which is lower than the first level. The bottom filter zone has multitude of bottom filter basins (51a-d) that are phase-displaced and periodically fed with the processed water in which a total flow of the water through the zone is constant. The substrate bottom of each bottom filter basin dries up periodically. The processed seawater is led over a trickling device in one of the bottom filter basins. The processed seawater is discharged from one of the bottom filter basins over drainage lines (53a-d), which are arranged under the entire bottom area of the bottom filter. A filter that prevents animal growth, is arranged to the upstream and/or downstream of bottom filter. A portion of the organisms is arranged in bags of strained nets transverse to the flow. A portion of the shells is fastened onto hawsers that are strained transverse to the direction of flow and/or hanging. The processed seawater is bubbled with gas in the biotope zone. The processed seawater exhibits a salt content of 10 parts per thousand. Independent claims are included for: (1) a water processing device; and (2) a swimming pool and a bathing pool.
