SEWAGE TREATMENT PLANT (STP)
Flush. Treat.Repeat.Engineered by Deur.
Turning everyday sewage into treated water for flushing, landscaping and a greener tomorrow.
- Reliable Treatment
- High Reuse
- Low OPEX
- Compact Design
An apartment building with an underground Deur STP. Sewage from the apartments passes through screening and grit removal, an equalization tank, biological treatment (SBR, MBBR, MBR or BIO STP), a secondary clarifier, filtration and disinfection into a treated water tank. Treated water returns for toilet flushing, landscaping and other reuse.
OUR STP TECHNOLOGIES

From sewage to cleaner, reusable water.
Our STP process combines physical, biological and advanced treatment technologies to remove contaminants and produce high-quality treated water.
- 01
Raw Sewage
From the building
- 02
Screening & Grit Removal
Removes debris, grit and floating matter
- 03
Equalization Tank
Balances flow through the day
- 04
Biological Treatment (MBBR)
Microorganisms break down organic matter
- 05
Secondary Clarifier
Settles biological solids from treated water
- 06
Filtration & Disinfection
Polishing and disinfection before reuse, as required
- 07
Treated Water
For flushing, landscaping and other non-potable reuse
Simplified process. The final design depends on sewage characteristics, capacity, site and reuse requirements.
