Chowunikira cha Turbidity cha TBG-2088S/P Paintaneti

Kugwedezeka, muyeso wa mitambo m'madzi, kwadziwika ngati chizindikiro chosavuta komanso choyambira cha ubwino wa madzi. Kwakhala kukugwiritsidwa ntchito poyang'anira madzi akumwa, kuphatikizapo omwe amapangidwa ndi kusefedwa kwa zaka zambiri. Kuyeza kugwedezeka kumaphatikizapo kugwiritsa ntchito kuwala, komwe kuli ndi makhalidwe odziwika bwino, kuti mudziwe kupezeka kwa tinthu tating'onoting'ono tomwe tili m'madzi kapena chitsanzo china chamadzimadzi. Kuwala kumeneku kumatchedwa kuwala kwa chochitika. Zinthu zomwe zili m'madzi zimapangitsa kuwala kwa chochitikacho kufalikira ndipo kuwala kumeneku komwe kwafalikira kumadziwika ndikuwerengedwa poyerekeza ndi muyezo wowerengera wotsatira. Kuchuluka kwa tinthu tating'onoting'ono tomwe tili mu chitsanzo kukakhala kwakukulu, kuwala kwa chochitikacho kufalikira kwambiri ndipo kugwedezeka komwe kumachitika kumakhalanso kwakukulu.

Tinthu tating'onoting'ono tomwe tili mkati mwa chitsanzo chomwe chimadutsa mu gwero lodziwika bwino la kuwala (nthawi zambiri nyali ya incandescent, diode yotulutsa kuwala (LED) kapena laser diode), tingathandize kuwononga chilengedwe chonse mu chitsanzo. Cholinga cha kusefa ndikuchotsa tinthu tating'onoting'ono kuchokera mu chitsanzo chilichonse. Pamene makina osefa akugwira ntchito bwino ndikuyang'aniridwa ndi turbidimeter, kutayika kwa madzi otuluka kudzadziwika ndi muyeso wochepa komanso wokhazikika. Ma turbidimeter ena sagwira ntchito bwino pamadzi oyera kwambiri, komwe kukula kwa tinthu tating'onoting'ono ndi kuchuluka kwa tinthu tating'onoting'ono kumakhala kochepa kwambiri. Kwa ma turbidimeter omwe alibe mphamvu pamlingo wotsikawu, kusintha kwa kutayika komwe kumachitika chifukwa cha kusweka kwa fyuluta kungakhale kochepa kwambiri kotero kuti kumakhala kosasiyana ndi phokoso loyambira la kutayika kwa chipangizocho.

Phokoso loyambira ili lili ndi magwero angapo kuphatikizapo phokoso la zida (phokoso lamagetsi), kuwala kobisika kwa zida, phokoso la chitsanzo, ndi phokoso lomwe lili mu gwero lokha la kuwala. Zosokoneza izi ndizowonjezera ndipo zimakhala gwero lalikulu la mayankho abodza a matope ndipo zimatha kuwononga malire ozindikira zida.

Mutu wa miyezo mu muyeso wa turbidimetric umavuta pang'ono chifukwa cha mitundu yosiyanasiyana ya miyezo yomwe imagwiritsidwa ntchito nthawi zambiri komanso yovomerezeka popereka malipoti ndi mabungwe monga USEPA ndi Standard Methods, komanso pang'ono chifukwa cha mawu kapena tanthauzo lomwe limagwiritsidwa ntchito pa iwo. Mu Kope la 19 la Standard Methods for the Examination of Water and Wastewater, kufotokozedwa kwafotokozedwa pofotokoza miyezo yoyambirira ndi yachiwiri. Standard Methods imafotokoza muyezo woyamba ngati womwe umakonzedwa ndi wogwiritsa ntchito kuchokera ku zinthu zopangira zomwe zingathe kutsatiridwa, pogwiritsa ntchito njira zolondola komanso pansi pa mikhalidwe yolamulidwa yachilengedwe. Mu turbidity, Formazin ndiye muyezo wokhawo wodziwika bwino woyambirira ndipo miyezo ina yonse imachokera ku Formazin. Kuphatikiza apo, ma algorithms a zida ndi mafotokozedwe a turbidimeters ayenera kupangidwa motsatira muyezo woyamba uwu.

Standard Methods tsopano ikufotokoza miyezo yachiwiri ngati miyezo yomwe wopanga (kapena bungwe lodziyimira pawokha loyesera) wavomereza kuti apereke zotsatira zowunikira zida zofanana (mkati mwa malire ena) ndi zotsatira zomwe zapezeka pamene chipangizocho chikuyesedwa ndi miyezo ya Formazin yokonzedwa ndi ogwiritsa ntchito (miyezo yayikulu). Miyezo yosiyanasiyana yoyenera kuwunikira ikupezeka, kuphatikiza zoyimitsidwa zamalonda za 4,000 NTU Formazin, zoyimitsidwa za Formazin zokhazikika (StablCal™ Stabilized Formazin Standards, zomwe zimatchedwanso StablCal Standards, StablCal Solutions, kapena StablCal), ndi zoyimitsidwa zamalonda za microspheres za styrene divinylbenzene copolymer.
