Modular wastewater treatment for a pharmaceutical plant: up and running in 5 working days
I designed a 50 m³/day wastewater treatment module for a pharmaceutical plant. The module was assembled and tested at the factory before shipment, so on site it took 3 working days to install and 2 to commission.

Input data
| Capacity | 50 m³/day |
|---|---|
| Format | modular plant: module assembled and tested at the factory before shipment |
| On-site installation | 3 working days |
| Commissioning | 2 working days |
| My role | module design, installation supervision, commissioning, analyses, handover |
Engineering challenge
A pharmaceutical plant needed a 50 m³/day treatment plant fast: no lengthy construction on site and start-up within days. Treated water is discharged to the ground, so treatment had to reach steady performance right after start-up.
Solution
All treatment except equalisation sits in one module. It was assembled and tested at the factory before shipment, so installation and start-up took 5 working days. The diagram below shows how it works.
Result
| On-site installation | 3 working days |
|---|---|
| Commissioning | 2 working days |
| Project | handed over to the client |
The solution step by step: effluent path from the plant to discharge
- 01
Equalisation
50 m³
Effluent flows by gravity into a tank with a Flygt jet aerator.
- 02
Chemicals
coagulant + flocculant
Pumps feed the module; mixing in the coagulation chamber.
- 03
DAF
KWI DAF Minicell
Removes suspended solids and flocs.
- 04
Polishing and discharge
multimedia filters
Clarified water is discharged to the ground.
Sludge
DAF sludge is dewatered in filter bags.
Speed of start-up
The module was assembled and tested at the factory: 3 working days to install on site, 2 to commission.
My role
Module design, installation supervision inside the module and on site, commissioning, analyses, staff training and handover.
