Overview
What sewage and effluent treatment do
Sewage and effluent need treatment before they can be reused for flushing and gardening or discharged. The right process — extended aeration, SBR, MBBR or MBR for sewage; physico-chemical and biological stages for effluent — depends on load, space and the quality you need.
Greenly designs and manufactures treatment plants and recycling systems, installs and commissions them, and trains your operators. We size every plant on actual flow and load, and design to the discharge norms that apply to your site.

- Decide where treated water will be reused.
- Check space available and whether the plant can be underground or above ground.
- Plan for sludge handling and for who will operate the plant.

Questions, answered
FAQs about Wastewater & Sewage Treatment
Still unsure? Ask us directly or call +91 95000 55565.
How is an STP sized?
An STP is sized on daily sewage flow (KLD), which depends on the number of people and the water use per person, plus a margin for peaks. We confirm the size after reviewing your site details.
What is the difference between an STP and an ETP?
An STP treats domestic sewage from toilets, kitchens and bathrooms. An ETP treats industrial effluent, which varies with the process and often needs chemical treatment before biological treatment.
Can treated water be reused?
Yes. Treated sewage is commonly reused for flushing, gardening and cooling towers. Additional polishing such as filtration and disinfection is added to suit the reuse.
Which technology is best for limited space?
MBBR and MBR plants need less space than conventional extended aeration. The final choice depends on load, budget and the treated water quality you need.
Do you help with operation after installation?
We commission the plant, train operators and offer service support. Operation and maintenance arrangements are confirmed with the quote.
Is STP sludge hazardous?
Domestic sewage sludge is generally non-hazardous. After dewatering it can often be used as manure, subject to local rules.
