Zusammenfassung: | The invention relates to a system with recirculated water used for intensively growing pikeperch during the first six months of life. According to the invention, the system comprises two units () for growing pikeperch juveniles and for conditioning the water, respectively, the first unit () being provided with fish pools () for growing the pikeperch juveniles, said pools being manufactured of polyester resins reinforced with glass fibres and provided with fish-tanks (), made of a mesh of synthetic material having a lower part () detachable by means of a slide fastener (), fixed on a frame () made of polypropylene which is also used for fastening some spray nozzles () in the proximity of some pipes () for supplying with pressurized water, whereto the water comes from a hydrophore set (), the second unit () being provided with a drum filter () for the mechanical filtration, a pool () for storing the filtered water, two float-controlled submersible pumps (), an installation () for sterilizing the water with ultraviolet radiation, a biologic filter () with nitrifying role, two air pumps () and an installation () for thermal conditioning of water.
Invenţia se referă la un sistem cu apă recirculată folosit pentru creşterea intensivă a şalăului în primele şase luni de viaţă. Sistemul conform invenţiei este constituit din două unităţi () de creştere a puietului de şalău şi, respectiv, de condiţionare a apei, prima unitate () fiind dotată cu nişte bazine () de creştere a puietului de şalău, realizate din răşini poliesterice armate cu fibră de sticlă, prevăzute cu viviere () din plasă de material sintetic, având o parte () inferioară detaşabilă prin intermediul unui fermoar (), fixate pe un cadru () realizat din polipropilenă, care serveşte în plus la fixarea unor duze () de spray-uri alături de nişte conducte () de alimentare cu apă sub presiune, la care apa ajunge de la un hidrofor (), a doua unitate () fiind prevăzută cu un filtru () tobă pentru filtrarea mecanică, un bazin () de stocare a apei filtrate, două pompe () submersibile cu plutitor de comandă, o instalaţie () de sterilizare a apei cu radiaţii ultraviolete, un filtru () biologic cu rol nitrificator, două pompe () de aer şi o instalaţie () de condiţionare termică a apei. |
