7. AHET is one of the first companies to deploy successfully
anaerobic technology for pharmaceutical (API) wastewater.
Anaerobic biodegradation breaks down complex molecules,
enhances biological treatment efficiency, reduces COD and
minimizes sludge generation for pharma industry wastewaters. The
use of anaerobic digestion reduces chemical consumption and
sludge generation by almost 30-40% compared to the conventional
treatment process and also ensures consistent treated effluent.
➢ Two-stage biological process reduces COD 85-90%, and plant
footprint by 30-35%
➢ Sludge generation is reduced by 30-40%
➢ Produces methane-rich biogas, which can be used as fuel
➢ Reduces overall power consumption by almost 25%
➢ Provides consistent quality of treated wastewater
➢ Incorporation of anoxic step will helps reducing total Nitrogen
➢ Option of remote monitoring

(India); Amway, Madurai (India)

8. ➤➤➤ Tertiary Treatment – SUFRO®
The SUFRO® system comprises high quality submerged
ultrafiltration (UF) membrane laminates with 38 nm pore size
followed by a reverse osmosis (RO) plant. This technology offers
huge benefits in terms of savings in chemicals, balance of
equipment, backwash water requirements, and space.
➢ A unique system that protects downstream RO membranes as
well as upstream biological treatment
➢ Can withstand high inlet suspended solids load upto 1000 ppm
➢ Eliminates sand filter, carbon filter, and UF
➢ Reduces backwash water and consumption of cleaning
chemicals
➢ 50% smaller footprint compared to conventional UF
➢ Easy to operate and control
➢ Plug and play
➢ Robustly engineered RO recycle systems offers maximum
recovery and enhanced membrane life
➢ Option of remote monitoring
Reference: Novozymes, Patalganga (India)

10. ➤➤➤ HUBER Disc thickener S - Disc
HUBER S – Disc is used for thickening of sludge
prior to dewatering. This improves dewatering
machine performance, reduces operating hours
incase of decanters.
HUBER Disc Thickener S-DISC
➢ Simple operating principle
➢ Minimum operator intervention
➢ High operating reliability
➢ Compact and closed design
➢ Accessible for full inspection
➢ Minimised wash water demand
➢ Wear-resistant stainless-steel parts
➢ Noiseless operation
➢ Specific power consumption <0.02 kWh/m3
➢ Hundreds of installations worldwide
Reference: Cipla, Patalganga (India)

➤➤➤ Solar Active Dryer
The HUBER Solar Active Dryer is a simple, natural and accelerated
sludge drying system. The specially designed turner helps sludge
spreading, granulation and transport in a greenhouse construction.
➢ Continuous sludge feeding possible, even during monsoon
➢ Suitable even for small sludge volumes from 1,000 tons per annum
➢ Sturdy design, low energy consumption of 0.015 kWh/kg of sludge
➢ True backmixing of sludge for a perfect drying and granulation
➢ Modular design
➢ Fully automatic operation (including feeding and withdrawal system
which is optional)
➢ Virtually operator-less operation
➢ Option of remote monitoring
➢ Optional use of exhaust heat to support solar drying

13. ➤➤➤ Packaged STP
The comprehensive treatment process comprises steps for
sedimentation, anaerobic-aerobic biodegradation and disinfection –
all combined in a single FRP tank. The combination of anaerobic-
aerobic biological system results in the removal of high BOD and
nitrogen in the treated stream. The air pumps used for aeration
ensure perfectly balanced mixing.
➢ 2-stage anaerobic-aerobic treatment process
➢ Compact, single FRP tank design
➢ Underground or over ground installation
➢ Modular construction
➢ Low operating cost
➢ Option of remote monitoring
