When do you need AHET services?
1. Wastewater treatment
plants are designed on the
basis of assumptions in feed
effluent quality, but the actual
conditions encountered are often
different
2. Additionally, due to changes in
product mix, production processes, use
of chemicals, or increase in production over a
period of time, the effluent quality and
quantity undergo changes from what was
originally envisaged
3. Both these scenarios
lead to deteriorating plant
performance and/or increasing
cost of operation
You can profitably use
AHET’s expert services in
such cases, to:
 improve the ETP and recycling
plant efficiency
 reduce the ETP and recycling
plant operating costs
 stabilise the operations of ETP
and recycling plant
 identify the root causes for
recurring issues and provide
long term solutions
 analyse the feasibility of
upgrading the existing ETP and
recycling plant without stopping
operations
 training of operating staff

 Provide detailed treatability study report

7. 7
Process optimisation studies
Process optimisation studies are designed to enhance the existing treatment
process to minimise process upsets and to improve system efficiency
Features:
 Carried out under expert supervision
 Characterise incoming effluent
 Undertake treatability and pilot trials, in case required
 Provide reliable, reproducible and practical suggestions
 Provide detailed report comprising optimised treatment steps for wastewater treatment,
recycling, and zero liquid discharge, as applicable
 Provide training for building competency of operators, chemists, and engineering staff

8. 8

biological systems
BBE-1 concentrate for fats, oil and grease removal includes a mixture of non-
bacterial active enzymes with a proprietary non-ionic surfactant package and
catalyst.
The surfactant in the BBE-1 concentrate acts as a wetting agent, reducing surface
tension and improving the enzymes’ ability to cleave organic contaminants,
thereby breaking down of fats, oil and grease molecules.

13. 13
Enzyme – BBE-2
Benefits:
 Cleaves complex organics
 Improves water quality and improves settling
 Decreases process upsets
 Removes malodours
 Achieves a balanced bacterial population
 Reduces residual/refractory COD
