| dc.description.abstract | Проведено гідрофілізацію полівініліденфлуоридних мембран (ПВДФ) внаслідок змішування з полівініловим спиртом (ПВС), і подальшим зшиванням із
глутаральдегідом. Синтезовані мембрани досліджені в процесах очищення поверхневих вод. Для вивчення поверхневої і поперечної морфології та міжмолекулярних
взаємодій проведені дослідження мембран з використанням скануючої електронної мікроскопії та спектроскопії Фур’є. Вивчено вплив параметрів, а саме: тиску, часу та
концентрації зшиваючого агента на ефективність процесу. Для прогнозування впливу концентраційної поляризації на ефективність розділення і частоту
зворотного промивання на основі експериментально встановлених даних граничного потоку, осмотичного тиску та моделі
блокування пор знайдено відповідну теоретичну модель. Встановлено, що модель осмотичного тиску є придатною моделлю,
а прогнозовані результати добре узгоджуються з експериментальними даними. Після перевірки моделі для синтезованої
мембрани, проведено симуляцію для прогнозування утворення осаду та визначено час зворотного промивання 97 год. Для підтвердження економічної доцільності
розробленого процесу проведено оцінку вартості пілотної установки потужністю 1000 м3/добу | |
| dc.description.abstract | Indigenous polyvinylidene fluoride (PVDF)
membrane was hydrophilized by blending with polyvinyl
alcohol (PVA) which was further cross-linked with
glutaraldehyde and tested for surface water purification.
Synthesized membranes were characterized by SEM and
FTIR to study the surface and cross-sectional morphologies
and intermolecular interactions, respectively. The effect of
parameters, namely feed pressure, operational time, and the
cross-linking agent concentration on the process efficiency
was studied. PVDF/PVA blend membrane exhibited a
reasonable process flux of 205 l/m2·h at 0.5 MPa and
ambient temperature of 308 K. Experimental data were
fitted to the limiting flux, osmotic pressure and pore
blocking model to find the suitable theoretical model to
predict the effect of concentration polarization on the
separation performance and back flushing frequency.
Osmotic pressure model was found to be a suitable model
and the predicted results from the model were in agreement
with the experimental findings. After the model was
validated for the synthesized membrane, the simulation was
carried out to predict the cake formation and the back
flushing time was found as 97 h. Cost estimation was carried
out for a pilot plant of capacity of 1000 m3/day to emphasize
the economic feasibility of the developed process. | |
