A distillery focused on the production of rectified spirits, denatured spirits, special denatured spirits, anhydrous alcohol and extra neutral alcohol required a water treatment system to meet their environmental sustainability goals. To recycle and reuse the effluent from the plant, the client decided to install an effluent treatment plant (ETP).
ઇટીપીમાં પરંપરાગત જૈવિક સારવાર છે અને ત્યારબાદ તૃતીય સારવાર પદ્ધતિ છે. ડિસ્ટિલરીએ તેમની પ્રક્રિયા અને કૂલિંગ ટાવર મેકઅપ વોટર અને બોટલ ધોવા જેવી ઉપયોગિતાના ઉપયોગ માટે રિવર્સ ઓસ્મોસિસનો ઉપયોગ કરીને ETP ટ્રીટ કરેલા પાણીને રિસાયકલ કરવાની યોજના બનાવી છે.
To ensure high quality permeate, the distillery decided to select ultrafiltration (UF) as an additional filtration step to get the required turbidity and ensures consistent product water quality suitable as feed for the downstream reverse osmosis (RO) process required for reuse. The parameters required for the RO feed water are SDI <3, Turbidity <0.2 NTU.
Since a high feed turbidity of up to 50 NTU was anticipated in the feed to the ultrafiltration system, the client decided to select PVDF-based outside-in UF membranes due to their capability to filter water with a high feed turbidity. The distillery evaluated various outside-in UF membrane options; the evaluation was based on the membrane surface area, the ability to withstand higher feed water turbidity and amount of waste generation. The system integrator finally selected Q-SEP 8012 UF membrane modules because of the following advantages they offer:
1. High membrane area of 80 m, requiring a lower number of membrane modules and footprint, resulting in capex savings for the distillery.
2. સતત ધોરણે 100 NTU સુધી ફીડ ટર્બિડિટીનો સામનો કરવાની ક્ષમતા.
3. Higher product recoveries due to a lower amount of UF filtrate used for maintenance cleaning.
મોડલ: Q-SEP® 8012
Q-SEP મેમ્બ્રેન: 25 સંખ્યા
Permeate Flow: 92m/hr (405 gpm)
એપ્લિકેશન: ETP વેસ્ટવોટર રિસાયકલ
કમિશનિંગ: ઓક્ટોબર 2020
QUA has supplied 25 Q-SEP® 8012 modules which are installed after the distillery’s tertiary treatment system as a pretreatment to the reverse osmosis system. The performance of Q-SEP PVDF outside in membranes on the distillery effluent has been very encouraging. The ultrafiltration system was commissioned in October 2020, and has been delivering consistent product flow and water quality since then. The product water turbidity has been consistently less than 0.2 NTU and Silt Density Index has been less than 3. Q-SEP UF membranes thus provided a consistent, durable solution for the distillery’s process water needs.
