SEWAGE TREATMENT PLANT- STP

Optima Water is a leading Sewage Treatment Plant manufacture in India offer both customized and standardized STP Plant.

A Sewage Treatment Plant (STP) is a facility that processes wastewater from residential, commercial, and industrial sources to remove contaminants and produce clean water that can be safely discharged or reused. STPs use a multi-stage process involving physical, chemical, and biological methods to purify the water and manage byproducts like sludge. This protects public health and the environment by preventing water pollution

Sewage is a resource that can be recycled for various uses like gardening, toilet flushing, car wash, cooling towers. 

Optima Water Solutions Design and Manufacture Different kind Of Sewage Treatment Plant.

CIVIL TANK BASED SEWAGE TREATMENT PLANT (Conventional STP)

Optima Water Solutions Design and Built Civil-Based Sewage Treatment Plant (STP) is a wastewater treatment system constructed in RCC structures at the site. All the tanks and treatment units — such as Collection Tank, Equalization Tank, Aeration Tank, Clarifier, and Sludge Tank — are built permanently with civil construction. It is a permanent and durable infrastructure designed for long-term operation (20–25 years or more).

• Civil construction allows customized layouts as per site conditions, flow, and load.
• Suitable for below-ground or partially underground installations.
• Tanks can be underground, saving space and improving site appearance.
• The top surface can be used for gardening, parking, or paving.

PREFABRICATED SEWAGE TREATMENT PLANT 

A Prefabricated Sewage Treatment Plant (STP) — also called a Packaged STP or Modular STP — is a factory-manufactured, ready-to-install wastewater treatment system, made from Mild Steel (MS), MSEP, MSFRP, or HDPE tanks.
It comes in modular form, assembled and installed at site with minimal civil work.

It is designed for small to medium sewage loads (5 KLD to 200 KLD) and is ideal for residential, commercial, and institutional projects where quick installation and compact design are required.

ADVANTAGES: 

• Ready-to-install system; requires only basic foundation and piping.
• Installation time is much shorter (1-2 weeks) compared to 3–6 months for civil-based STP.
• Modular design takes up less space; ideal for small plots, basements, or retrofitted buildings.
• Prefabricated units can be shifted or relocated easily.
• Only a simple concrete base or support slab is needed.
• Saves construction cost, labor, and project time.

CONTAINERIZED SEWAGE TREATMENT PLANT 

Optima Water Solution Design and Manufacture Containerized Sewage Treatment Plant (CSTP). It is a fully assembled, plug-and-play wastewater treatment system that is built inside a standard shipping container (typically 20 ft or 40 ft). These plants are designed to treat domestic or industrial sewage efficiently without requiring large civil construction work.

They are prefabricated, modular, and portable, making them ideal for temporary sites, remote areas, or locations where quick installation and mobility are important.

Advantages: 

• Compact and self-contained unit
• Easy transportation and installation
• Fabricated from corrosion-resistant materials
• Equipped with all treatment units like collection, aeration, clarification, filtration, and disinfection
• Can be customized as per the capacity (from 10 KLD to 100 KLD or more)

Treatment Technologies Used:

Containerized STPs can be designed using various biological treatment technologies such as:

• MBBR (Moving Bed Biofilm Reactor)
• MBR (Membrane Bio-Reactor)
• SBR (Sequencing Batch Reactor)

Reed Bed / Root Zone Filtration Based Sewage Treatment Plant (STP)

A Reed Bed Sewage Treatment Plant (STP), also known as a Root Zone Filtration System or Constructed Wetland System, is a natural, eco-friendly, and low-cost method for treating domestic or organic wastewater.
It uses plants (like reeds, cattails, or canna) and gravel/sand beds to biologically treat sewage through natural filtration and microbial activity around plant roots.

The system mimics the natural purification process of wetlands.
Wastewater passes through a series of layers—gravel, sand, and soil—planted with reeds or wetland plants.
As water flows slowly through these layers:

• Microbes attached to the root surfaces degrade organic matter.
• Plant roots absorb nutrients like nitrogen and phosphorus.
• Soil and gravel filter out suspended solids.

The final water coming out is clear, odor-free, and suitable for gardening, landscaping, or flushing use.

BIO-Digester Sewage Treatment Plant 

The BIO-digester is a sustainable, eco-friendly sanitation system that uses anaerobic microbial bacteria to decompose human waste. This "flush and forget" technology converts waste into clean, usable water and harmless biogas (methane and carbon dioxide), with no need for a conventional sewage system. 

How it works

1. Specialized inoculum: The system is charged once with an Anaerobic Microbial Inoculum (AMI) developed DRDO. The consortium of bacteria can withstand extreme temperatures, from -20°C to +50°C, making it suitable for various climates.
2. Anaerobic digestion: The biodigester tank, which can be made of mild steel, fiber, or reinforced cement concrete (RCC), uses an anaerobic process, meaning no oxygen is required. The AMI feeds on the fecal matter and multiplies on its own, continually breaking down the waste.
3. Output: The biodegradation process results in three outputs:

• Usable water: The effluent is odorless, colorless, and free of pathogens. It can be used for gardening, horticulture, or recycled for flushing, without polluting the groundwater.

• Biogas: The remaining gas, a mixture of methane and carbon dioxide, is continuously released into the atmosphere or can be utilized for energy purposes.

• No sludge: The system achieves a waste reduction of up to 99%, and there is no accumulation of sludge, so the tank never needs to be emptied. 

Advantages 

• Low maintenance: After the initial one-time charge of bacteria, the system is self-sustaining and requires very little maintenance.
• Environmentally friendly: It eliminates the contamination of soil and groundwater by converting waste into non-hazardous products.
• Space-saving: The units require significantly less space than conventional septic tanks, making them suitable for crowded areas.
• Customizable: The tanks can be custom-made to fit the needs of individual houses, apartment complexes, or other institutions.

Cost-effective: Over the long term, the minimal maintenance and resource recovery make it more economical than traditional waste disposal methods.
