Biological Treatment.
Membrane bioreactors and aerated biofilm systems that remove the organic load.
Biology does the heavy lifting on organic pollution. RTW builds membrane bioreactors and biofilm systems that produce a consistently clear effluent in a compact footprint, and that keep performing when loads swing with production.
Removes
BOD, COD, ammonia and nitrogen
Used in
What we manufacture.
Each unit is sized from lab tests on your own effluent and built in our facilities in Saudi Arabia, Bahrain and Pakistan.
Membrane bioreactor (MBR)
Biological treatment with submerged membranes in place of a clarifier — clear, disinfected permeate in a small footprint, ready for reuse or for feeding reverse osmosis.
Membrane aerated biofilm reactor (MABR)
Oxygen delivered through gas-permeable membranes to a biofilm, which cuts aeration energy sharply and removes nitrogen in a single tank. Also used to upgrade existing tanks.
Package sewage treatment plant
Complete biological plant for compounds, camps and developments, delivered as a civil-built or containerized package with TSE-quality output.
Why it matters.
- Reuse-quality effluent without a separate filter
- Smaller footprint than conventional systems
- Stable through production peaks
- Low odour, enclosed designs
