Insait long ol wara tritmen plent, ol kemikel dosing — moa yet ol 'flocculants' na 'coagulants' — i save afektim stret kwaliti bilong wara na pe bilong wok. Viskositi bilong 'flocculant' (olsem 'polyacrylamide PAM') i klostu long hevi bilong molekiul na konsentresen bilong en, we i save makim gutpela wok bilong 'flocculation'.
Insait long ol wara tritmen plent, ol kemikel dosing — moa yet ol 'flocculants' na 'coagulants' — i save afektim stret kwaliti bilong wara na pe bilong wok. Viskositi bilong 'flocculant' (olsem 'polyacrylamide PAM') i klostu long hevi bilong molekiul na konsentresen bilong en, we i save makim gutpela wok bilong 'flocculation'. Sapos ol i no givim planti marasin, dispela i mekim na i no gat inap 'flocculation' na 'effluent turbidity' i winim mak bilong en; sapos yu givim planti marasin tumas, dispela inap long mekim 'sludge' i go antap, na dispela inap long pasim 'filter cloth'.
Long Saut-is Esia na Afrika, ol ples bilong klinim wara i save bungim bikpela hevi tru. Wara we i save kamap long ol dispela hap i save gat planti 'organic matter' na ol 'suspended solids' (olsem ol 'humic substances' insait long ol 'tropical rainforest' eria, ol 'agricultural runoff' klostu long ol taun), na i nidim planti 'flocculant' moa long ol ples we i gat hatpela san. Long wankain taim, ol wara plent long ol dispela rijon普遍面临tait opereting baset na ol teknikel tim i no gat planti wokman, na dispela i putim bikpela pe long givim marasin stret.
Testing bilong 'viscosity' em i nambawan rot bilong stretim mak bilong 'flocculant'. Long rot bilong skelim 'viscosity' bilong ol 'flocculant' solusen long ol narapela narapela konsentresen, ol i ken kamapim wanpela 'viscosity-dosage-effluent turbidity' korelesen model bilong painim gutpela 'dosing point'. Insait long ol wara plent bilong Saut-is Esia na Afrika, dispela model i ken helpim long daunim ol kemikel pipia long 10%-30% — em i wanpela bikpela seving bilong ol plent we i no gat planti mani.
Testing bilong viskositi bilong 'floculant solution' i gat ol samting bilong en yet. Namba wan, 'viscosity' bilong ol 'flocculants' (espeseli 'high-molecular-weight PAM') i klostu long 'shear rate' - bikpela 'shear' i save stretim ol 'polymer chains' moa yet, na i save daunim viskositi. Dispela i min olsem ol i mas bosim gut spit bilong spindel na tempereja bilong tes.
NDJ-1F dijitel rotesenel viskomita i sapotim steples spit adjustmen long 0.1-100 rpm, wantaim No. 1-4 standet spindel, we i mekim ol i ken kisim gut 'rheological behavior' bilong ol 'flocculant solutions' long olgeta 'shear rates'. Long ol wara plent QC leboretori, dispela inap em i wanpela ki seleksen kraeteria.
Ol kondisen bilong fil tes long ol wara tritmen plent bilong Saut-is Esia na Afrika i save stap isi tasol. Planti diwai i no gat ea kondisen, na tempereja bilong lab inap long winim 35°C. Ol bikpela hat i save daunim viskositi bilong 'floculant solution', na dispela i save mekim tes i no stret. FangService's NDJ-1 series i gat wanpela 'temperature probe' na 'automatic temperature compensation', we i save rekodim 'temperature' bilong sempel taim ol i testim na stretim ol 'viscosity readings', na dispela i save givim gutpela data maski long ol ples we i gat bikpela hat.
Na tu, ol wara tritmen plent long Saut-is Esia na Afrika i save bungim pawa 'outage' planti taim. NDJ-1 series i gat liklik pawa disain na dispela i min olsem em inap long pinisim tes bilong nau long yusim bek-ap pawa bihain long pawa i pinis, na i no gat data i lus — wanpela samting we i bikpela samting tru long ol rijon we pawa i save pawa planti taim (Nigeria, Pakistan, Cambodia).
Pasin bilong rausim wara long 'sludge' em i narapela bikpela wok insait long ol ples bilong klinim wara. Ol 'rheological properties' bilong 'sludge' - 'viscosity' na 'yield stress' bilong en - i save mekim wok bilong makim ol masin bilong rausim wara na ol samting bilong en. Sludge we i tik tumas em i hat long pamim; 'sludge' we i liklik tumas i no inap long rausim wara.
Long Saut-is Esia na Afrika, ol pipia pipia i gat planti 'organic' na planti wara (98%-99%), na dispela i mekim hat long rausim wara. Sapos ol i putim ol 'flocculants' long stretim ol 'rheological properties' bilong 'sludge' dispela inap long helpim tru wok bilong rausim wara long ol 'belt filter presses' na 'centrifuges'. Viskositi tes long hia i helpim long stiaim wanem kain 'flocculant' na makim mak bilong en, na long lukluk long ol senis long 'sludge rheological' pasin pastaim na bihain long rausim wara.
FangService's DVPlus+ LV 'touchscreen viscometer' i gat ol 'low-viscosity spindles' (long 0.1-1000 mPa·s), we i gutpela tru long skelim 'viscosity' bilong 'supernatant' na 'thin sludge'. 'Touchscreen interface' bilong en i sapotim ol 'custom test' rot, na larim ol enjinia bilong wara plent long makim ol 'sludge viscosity-dewatering efficiency' tes wokflo we ol i save yusim planti taim long wanpela tats operesen, na dispela i mekim wok i kamap gutpela moa.
Taim yu makim ol 'viscometers' bilong ol wara tritmen plent long Saut-is Esia na Afrika, yu mas painim gutpela pefomens, gutpela wok, na pe bilong en.
Entry-level rekomendesen: NDJ-1 dijitel rotesenel viskomita. Em i gat strongpela straksa, isi wok, na prais bilong en i no antap tumas (inap olsem RMB 8,000-12,000), na i gutpela long mekim wok painimaut long 'flocculant viscosity' long olgeta de insait long ol 'water plant QC labs'. Bodi bilong en we i gat ain na disain bilong en i pas long en i save sakim ol ples we i gat wara na i save bagarapim ol samting we i save kamap long ol ples bilong klinim wara.
Mid-range rekomendesen: NDJ-1E+ dijitel rotesenel viskomita. Em i putim 'touchscreen display', 'data storage', na USB 'export' antap long 'entry-level model', na i sapotim ol 'method saving' na 'audit trails', we i gutpela long ol wara plent we i nidim ol gutpela rekot bilong QC.
Premium rekomendesen: DVPlus+ series 'touchscreen viscometer'. I gat 7-inch 'touchscreen', 'automatic multi-spindle recognition', na 'temperature-controlled testing', we i gutpela long ol 'comprehensive water treatment lab' we i mas sekim ol 'flocculants', 'sludge', na 'effluent quality' wantaim. Data menesmen sistem bilong en i sapotim wok bung wantaim ol laboratori infomesen menesmen sistem (LIMS), na i bihainim ol strongpela lo.
Spesel rekomendesen: Long ol hap we pawa i save pinis planti taim, putim tu wanpela UPS (inap 30 minit bilong wok) na ol spesel bateri. FangService's NDJ-1 series i gat ol spesel bateri olsem standet, we i larim tes bilong nau i pinis na data i stap bihain long pawa i bagarap.
Taim ol i wokim 'viscosity testing capacity' insait long ol wara tritmen plent long Saut-is Esia na Afrika, mipela i rekomendim 'liklik step, hariap iteresen' rot.
Step 1: Kisim wanpela NDJ-1 dijitel rotesenel viskomita wantaim ol samting yu nidim (konstant-temperature bat, standet spindel, kalibresen fluid), olgeta kos em inap olsem RMB 15,000-20,000. Givim 2-3 de bilong besik operesen trening long ol teknikel wokmanmeri.
Step 2: Bungim ol data bilong 'correlation' namel long 'flocculant viscosity' na 'effluent turbidity' long taim bilong wok long olgeta de, na kamapim wanpela 'optimal dosing viscosity range'. Dispela data i gat bikpela pe moa long ol jenerik refrens veliu bilong ol saplaia.
Step 3: Apgredim ol ikwipmen bihainim ol nid tru. Sapos ol ikwipmen i stap pinis i no inap long inapim ol nid bilong testim sampela sempel (olsem ol 'high-viscosity sludge' o ol sempel we i no gat planti 'viscosity'), tingim long apgredim i go long DVPlus+ series o putim ol spesel aksesori.
FangService i save givim teknikel sapot na ol spesel pat saplai bilong ol wara tritmen plent long Saut-is Esia na Afrika. Mipela i gat ol sevis senta long Bangkok, Jakarta, Nairobi, na Lagos, we i save givim hariap bekim na trening long ples. Na tu, mipela i save givim wanpela 'Flocculant Viscosity Testing Standard Operating Procedure (SOP)' templet we i stret long wara tritmen indastri, na i sapotim tok Inglis, Frans, Swahili, na Indonesia, na i helpim ol kampani long kamapim hariap ol tes sistem we i stret long lo.
