​Frequently Asked Questions (FAQs)

 

1. What is a Sewage Treatment Plant (STP) and how does it work?

A Sewage Treatment Plant (STP) is a facility designed to treat and purify wastewater from residential, commercial, or industrial sources. It typically involves stages like primary clarification, aeration (biological treatment), and sludge separation, followed by disinfection. This process ensures the treated effluent meets environmental discharge standards or can be reused.

 

2. Which STP technology is best for residential or small-scale projects?

For residential societies, schools, or small hotels, compact systems like MBBR (Moving Bed Bio Reactor), SAFF, or SBR (Sequential Batch Reactor) are ideal. These are low-maintenance, energy-efficient, and can be containerized or skid-mounted for space-saving installation.

 

3. What is the difference between STP and ETP systems?

An STP (Sewage Treatment Plant) treats domestic wastewater (from kitchens, bathrooms, etc.), while an ETP (Effluent Treatment Plant) is designed for industrial wastewater, which may contain chemical or hazardous substances. Zeta4 Water Solutions offers consultancy to choose the right system based on your application.

 

4. Do you provide installation and AMC (Annual Maintenance Contract) services?

Yes, Zeta4 Water Solutions provides end-to-end services, including design, supply, installation, commissioning, and AMC support. Our team ensures smooth operation and compliance with environmental regulations throughout the plant’s lifecycle.

 

5. Can STP-treated water be reused?

Absolutely. Treated water from STPs can be reused for flushing, landscaping, cooling towers, or even agricultural irrigation, depending on the treatment level. Our systems help in maximizing water recycling, promoting sustainability, and reducing overall water consumption.
