Industries generate significant volumes of sewage containing organic matter, suspended solids, oils, chemicals, and pathogens. An Automatic Industrial Sewage Treatment Plant (STP) is engineered to treat this wastewater, ensuring it meets environmental discharge norms or is suitable for reuse in non-potable applications like gardening, flushing, or cooling towers. The plant’s automation ensures consistent treatment quality, low manual intervention, and operational efficiency.

An Industrial Sewage Water Treatment Plant (STP) is designed to treat wastewater generated from industrial processes, staff facilities, and other on-site activities. It ensures that the effluent discharged into municipal sewers, rivers, or reused within the facility complies with environmental standards and regulatory norms.

✅ 1. Preliminary Treatment

• Screening of large solids (plastic, cloth, etc.)

• Grit removal to separate sand and silt

✅ 2. Primary Treatment

• Sedimentation tanks for settling suspended solids

• Removal of floating oil and grease

✅ 3. Secondary (Biological) Treatment

• Activated sludge process or MBBR/MBR systems

• Biological degradation of organic pollutants

• Aeration tanks for microbial growth

• Clarifiers to separate biomass

✅ 4. Tertiary Treatment

• Sand filtration or pressure filtration

• Activated carbon filters for color, odor, and chemical removal

• Disinfection through UV, chlorination, or ozone treatment

✅ 5. Sludge Handling

• Sludge thickening and dewatering

• Drying beds, filter press, or centrifuge systems

• Safe sludge disposal or composting

Effluent Treatment Plant or ETP is one type of waste water treatment method which is particularly designed to purify industrial waste water for its reuse and it's aim is to release safe water to environment from the harmful effect caused by the effluent.

Commercial establishments such as hotels, hospitals, residential complexes, office buildings, malls, and educational institutions generate significant volumes of sewage containing organic matter, suspended solids, oil, grease, and pathogens. A Commercial Sewage Treatment Plant (STP) is engineered to treat this wastewater to safe levels for discharge into municipal sewers, surface water bodies, or for reuse in applications such as gardening, toilet flushing, and cooling towers.

Modern commercial STPs are designed to be compact, energy-efficient, low-maintenance, and compliant with stringent environmental regulations.

A Domestic Sewage Treatment Plant (STP) is a compact and efficient system designed to treat household wastewater from kitchens, bathrooms, toilets, and washing areas. It ensures that water discharged into the environment or municipal drains is safe, odor-free, and compliant with regulatory standards.

Domestic STPs are ideal for individual homes, small residential buildings, villas, gated communities, farmhouses, and small institutions. They help conserve water by enabling treated wastewater to be reused for gardening, flushing, and landscaping.

⚙️ How It Works

Domestic STPs treat sewage in several stages:

1. Screening: Removes large particles like hair, plastics, and debris.

2. Equalization: Balances flow fluctuations from daily household use.

3. Primary Treatment: Settles suspended solids through sedimentation.

4. Biological Treatment: Degrades organic matter using bacteria (via methods such as MBBR, SBR, or ASP).

5. Secondary Clarification: Settles biological sludge.

6. Tertiary Treatment: Filters and disinfects water using sand filters, activated carbon, and UV or chlorine.

7. Sludge Handling: Safely removes and disposes of sludge.
