Revitaliztion of water well - Srebrenik

U Valjevu je u oktobru 2018.g. održan 39. Međunarodni stručno-naučni skup “Vodovod i kanalizacija” na kojem je prezentovan i rad pod naslovom “Rezultati izvedene fizičko-hemijske revitalizacije bunara B-7 na izvorištu vodovoda Opštine Srebrenik” autora Vaso Novaković, Nikola Nikolić, Sanel Buljubašić, Aleksandar Tomić, Ranko Grujić. Tokom višegodišnjeg rada kapacitet bunara se smanji, u većini slučaja na jednu trećinu početnog kapaciteta, a povećaju se hidraulički otpori na otvorima filtera i u pribunarskoj zoni zbog njenog kolmiranja sitnozrnim česticama i inkrustacije mineralnih soli. Zbog toga je u okviru održavanja bunara, svakih 2 do maksimalno 5 godina neophodno izvršiti fizičko-hemijsku revitalizaciju bunara, koju izvode specijalizovana preduzeća koja se bave i izvođenjem bunara. U radu su prezentovane i obrađene primijenjene metode revitalizacije bunara i rezultati testiranja bunara B-7 na izvorištu Vlahulje vodovoda Srebrenik u Bosni i Hercegovini, prije i poslije revitalizacije koju je izvelo preduzeće DOO “IPIN” iz Bijeljine. Rezultati do kojih se došlo prilikom izvođenja snimanja i testiranja bunara B-7 vodovoda Srebrenik, prije i nakon sprovedene fizičko-hemijske revitalizacije, ukazuju da su postignuti odlični rezultati, koji se ogledaju u smanjenju bunarskih otpora čak oko 8 puta i povećanju specifičnog kapaciteta za oko 2,8 puta, a i povećanju optimalnog kapaciteta bunara B-7 sa 8 na 22,2 l/s ili skoro za tri puta, što je čak nešto veći kapacitet nego kada je bunar bio nov.
