Matambudziko Anowanikwa muReverse Osmosis Membrane Operation (Chikamu 2)
- High TDS Levels
High total dissolved solids (TDS) mazinga mumvura yechigadzirwa anoratidza kuti membrane haisi kunyatsobvisa zvinosvibisa. Izvi zvinogona kuve nekuda kwekusvibiswa kwemembrane, kuyera, kana kukanganisa membrane. Kugara uchitarisa uye kugadzirisa kwakakosha kuchengetedza TDS mazinga.
- Kakawanda Sefa Shanduko
Kana mafirita achida kuchinjwa kakawanda kupfuura zvamazuva ese, zvinogona kunge zviri nekuda kwekushata kwemvura yemhando yepamusoro kana kuti ine undersized system. Kuve nechokwadi chekurapa kwakakodzera uye kusarudza saizi chaiyo system inogona kubatsira kuderedza kuwanda kwekuchinja kwesefa.
- Biofouling
Biofouling inoitika apo tupukanana tudiki senge mabhakitiriya uye algae zvinokura pa membrane pamusoro. Izvi zvinogona kukonzera kuvhara uye kuderedza kushanda zvakanaka. Kugara kuchenesa nemabiocides uye kuchengetedza hutsanana hwakakwana hwemvura yekudyisa kunogona kubatsira kudzivirira biofouling.
- Chemical Attack
Mamwe makemikari, akadai seklorini, anogona kukuvadza RO membrane, zvichitungamira mukuderedzwa kwekuita uye hupenyu. Kushandisa dechlorination nzira, dzakadai activated carbon filters, mvura isati yasvika pa RO membrane inogona kuidzivirira kubva pakurwiswa kwemakemikari.
- Pressure Drop
Kudonhedza kwakakosha kudonha pa membrane kunogona kuratidza kusvibisa kana kuyera. Kuongorora kusiyanisa kwekumanikidza uye kuita nguva dzose kugadzirisa kunogona kubatsira kuziva uye kugadzirisa chikonzero chekudonha kwekumanikidza.
- Membrane Kuchembera
Nekufamba kwenguva, RO membranes inodzikisira uye inorasikirwa nekuita kwayo. Izvi zvinogona kukonzera kuderera kwehutano hwemvura uye kuderedza kuyerera kwemazinga. Kugara kurongwa membrane kutsiva kwakakosha kuchengetedza mashandiro ehurongwa.
- Kusakwana Pretreatment
Kusanyatsogadziriswa kwemvura yekudyisa kunogona kutungamira kune dzakasiyana nyaya, kusanganisira kusvibisa, kuyera, uye biofouling. Kuve nechokwadi chekugadzirisa kwakaringana, senge sediment filtration, kupfava, uye pH kugadziridzwa, kunogona kuwedzera zvakanyanya hupenyu uye kushanda zvakanaka kweiyo RO membrane.
