Effluent Segregation
•Gaseous streams which are generated intermittently
•Carcinogenic Streams
•Hazardous Streams e.g. Cyanide
• Low TDS & High COD Streams
![Page 9: Zero Liquid Discharge for Pharma - Industrial Green …industrialgreenchem.com/pdf-docs/Praj.pdf 11 Using Lesser capacity Axial Pumps •Axial Pumps are cheaper than Centrifugal Pumps](https://reader033.vdocuments.us/reader033/viewer/2022041804/5e535ffab7ec327bb759ef83/html5/thumbnails/9.jpg)
9 www.praj.net
Inefficient Stripping of Solvents
•Results in high COD in MEE condensate
•Gases like Ammonia increases the Heat exchange area required in MEE,
hence need to be take care separately
• High Steam Consumption in MEE
• Reduction in MEE capacity
![Page 10: Zero Liquid Discharge for Pharma - Industrial Green …industrialgreenchem.com/pdf-docs/Praj.pdf 11 Using Lesser capacity Axial Pumps •Axial Pumps are cheaper than Centrifugal Pumps](https://reader033.vdocuments.us/reader033/viewer/2022041804/5e535ffab7ec327bb759ef83/html5/thumbnails/10.jpg)

Using Falling Film
ADVANTAGES:
• Better Heat Transfer Coefficient -Lesser Area - Lower Capex
• Low Power consumption - Lower Opex
• Can be started up quickly and changed to cleaning mode - Low Down time
• Useful in heat sensitive chemical solutions - Lower Residence Time / lower Holdup
STEAM
COND.
FEED
VAPORS
LIMITATIONS:
• Not suitable at higher suspended solid concentration and higher viscosity. - Limited Application
• Distribution system is critical and can lead to tube fouling in absence of adequate wetting rate. – Critical operation
• Frequent C.I.P. Required . – requires actual experience to confirm cleaning frequency

Using Lesser capacity Axial Pumps
•Axial Pumps are cheaper than Centrifugal Pumps
•Handles large flow rates but Low Head, hence, 1-2 Tube passes has to be
taken
•Can not Manage Pump heads
•Compared with Centrifugal pump, if axial pump flows are less, the
calendria tubes will lead to have liquid & Vapor phases resulting into
scaling & plugging
•Heavy Maintenance Problems

12 www.praj.net
High scaling & cleaning Frequency of MEEs
•Resulting in frequent cleaning and even Jet cleaning
•Due to Jet cleaning system is to be designed overall 18-20 hrs as against
24 hrs thus resulting in nearby 17% more cap. thus increasing CAPEX
• Frequent cleaning increases effluent volume thus further issues with the
MEE to handle increased load

Worst Scenario Design
WORST CASE DESIGNS
o TS consideration more - Increase in overall CAPEX & OPEX
o Hydraulic rate more - Frequent shutdowns – More effluent generation
– more chemical cost

Photo Chemical Oxidation (Advanced Oxidation)
New Technologies

• Advanced wastewater treatment using
photochemical oxidation.
• It destroys/treats non-biodegradable organic
contaminants present in wastewater, which
are generally represented as “Recalcitrant
Chemical oxygen demand”.
• Photochemical oxidation is enhancing the
oxidation rate with the help of ultraviolet
light in presence of oxidizing chemicals such
as hydrogen peroxide, ozone etc

UV Activation
Oxidant CO2+ H2O
Pollutant and oxidant are elevated to an
activated state wherein the oxidation rate
increases multifolds. As a result, the COD
contributing molecules are broken down,
oxidised and leave the effluent stream in the
form of CO2 and H2O
