Color Removale System

Established technology that removes colour from waste water generated in textile processing and printing houses, to products clear water which can be further treated for reuse Designed specifically for textile process houses - removes 100% colours Available range - from 0.1 to 50 m3/h Low power requirements Low capital investments Standardised designs - hence quicker deliveries Nominal civil work


Bio - Filter

• A compact,reliable,robust,and low maintenance sewage treatment system for low flow capacities

• Principle: System is based on facultative aerobic treatment using a bio-filter and aerobic digestion system in a single stage module

• Standard Range:- 10,20,30,50,m3/day of sewage treatment


Sewage Recycle Treatment

Fab reactors. Fluidized aerobic bio reactors-an ideal solution for sewage treatment . Thermax was the first indian company to come out with the most advanced technology of fluid bed for aerobic treatment. This is based on attached growth principle by bacterial growth on the medias with reduction of bod/cod content in the presence of oxygen available from the air that is used for fluidization.



Membrane Bio-Reactor (MBR) is the latest advancement in the field of waste water treatment. Using membranes to treat and recycle sewage, these systems give the best quality of treated sewage. Today, Thermax provides solutions in both submerged type as well as side stream type membrane. These solutions are the best in class and cost effective.


• Produces high quality treated water; this can be directly fed to RO

• Elimintes secondary clarifier, filteration and disinfection units

• It has no sludge settling problems

• Reduced tank volumes – almost 25% of ASP and up to 50% of that of SBR

• Reduces construction cost

• Small footprint due to high concentration of biomass

• Low sludge generation due to long sludge age

• More robust to load variations

• Free from regular problems like filamentous growth, bulking, floating sludge, etc.

• Can be made fully automated with zero manual intervention

• Easy expansion – retrofitting – capacity enhancement



:- A Complete Solution For Solid Waste Disposal

• Specially designed to treat solid waste of infectious and hazardous natures

• Available range- from 8 to 250 kg/h and 300 to 1500 kg/h

• Unique,indigenous multi-chamber design

• Based on controlled air principle

• Minimum site work required for erection and commissioning
