KIRISH
Ultrafiltratsiya qurilmalarining ishlashida muhim vazifa membranalarda ifloslantiruvchi moddalarning to'planishi jarayonini nazorat qilish va boshqarishdir. Ushbu muammoni hal qilish, birinchidan, membrana ifloslanishi minimal bo'lgan membrana qurilmalarining ishlash rejimini yaratishdan, ikkinchidan, ma'lum bir manba suvining ifloslanishiga eng kam sezgir bo'lgan mos membrana materialini tanlashdan iborat.
TADQIQOT MATERIALLARI VA METODOLOGIYASI
Bundan tashqari, membrana elementining dizayni o'zi membranani maksimal samaradorlik bilan gidravlik yuvish imkonini berishi zarur.
Membrana yuzasi ustidagi cho'kindi o'sishiga qarshi kurashish uchun tozalangan suyuqlikdan qo'shimcha oqim hosil bo'ladi, bu esa to'plangan cho'kindini xiralashtiradi. Membrananing yuzasidan chiqarilgan ifloslantiruvchi moddalarni o'z ichiga olgan suyuqlik (konsentrat) ajratish qurilmasidan chiqariladi.
TADQIQOT NATIJALARI
Ifloslantiruvchi moddalarni sirtdan va membrananing teshiklaridan samaraliroq olib tashlash uchun teskari yuvish usuli qo'llaniladi, bunda tozalangan suv (filtrat) filtrlash yo'nalishiga teskari yo'nalishda membrana orqali o'tkaziladi. Bunday yuvishlar donador yuklanish bilan an'anaviy filtrlarni yuvishdan ko'ra tez-tez amalga oshiriladi - yer usti suvlarini tozalash uchun mo'ljallangan ultrafiltratsiya membranalari uchun ularning chastotasi soatiga 1 dan 4 martagacha o'zgarib turadi, lekin yuvish davomiyligi atigi 10-60 sekund, shuning uchun chiqarilgan suv hajmi filtrat hajmining 5% dan oshmaydi. Ultrafiltratsiya membranalari yordamida suvni tozalash jarayoni sxemasi 2 -rasmda ko'rsatilgan .

Ultrafiltratsiya qurilmalarini ishlashning asosiy sxemalari
a - ish aylanishi (filtrlash); b - yuvish davri.
Ko'pgina zamonaviy polimerik membranalar mikroorganizmlarga va kimyoviy birikmalarga 2 dan 11 gacha bo'lgan keng pH diapazonida chidamli (ba'zi membranalar kimyoviy yuvish paytida pH ning 1 dan 14 gacha o'zgarishiga imkon beradi), yuqori selektivlik va mahsuldorlikka ega, ammo kuchli oksidlovchi moddalar: erkin xlor, yod, ozon ni o'tkazmaydi. Membranalarning xususiyatlari butun xizmat muddati davomida faqat bir oz yomonlashadi, bu besh yil yoki undan ko'proq. Membrananing eskirishi tozalangan suv tarkibidagi to'xtatilgan va abraziv moddalar yoki kimyoviy tozalash vositalari bilan o'zaro ta'sirlashganda yuqori qatlamning yupqalashishi tufayli yuzaga kelishi mumkin. Cheklangan ish harorati 40-45 ° C ni tashkil qiladi, ba'zida 50 ° C gacha qisqa muddatli o'sishga ruxsat beriladi.
Boshi berk va o'zaro oqim rejimda ishlovchi ultrafiltrlarni taqqoslashda asosiy e'tibor tizimning foydali ishlashi va energiya sarfiga qaratiladi. Ma'lumotlarga ko'ra, boshi berk filtrli tizimlar uchun foydali ishlash mos ravishda 55-80 dan 90-98% gacha, o'zaro oqim rejimi uchun esa 75-90 dan 90-96% gacha va umuman olganda boshi berk rejimi yanada tejamkor. Muhim omil - bu elektr energiyasini iste'mol qilish: boshi berk filtrlash uchun u taxminan 0,18-0,22 kVt / m 3 ni tashkil qiladi - bu o'zaro oqim bilan filtrlashdan ancha kam, -0,54-0,72 kVt / m 3.
Boshi berk rejimida ishlovchi ultrafiltratsiya membranasi qurilmasining ishlashi umumiy ma'noda quyidagi formula bilan tavsiflanadi:

Q =

Bu yerda : AP - membrananing ustidagi va ostidagi bosim farqi ; S - qurilmadagi membrana yuzasi ; ^ — suvning dinamik yopishqoqligi ; Rm -membrana qarshiligi; Rq — uning teshiklari tiqilib qolishi tufayli membrananing qo'shimcha qarshiligi; Rq,ch membrana yuzasidagi cho'kindining qarshiligi.
