Sewage Treatment Plant (STP)

Sewage Treatment Plant (STP)

A Sewage Treatment Plant (STP) plays a vital role in treating wastewater from homes, businesses, and industries before it's released into the environment. It uses a combination of physical, chemical, and biological processes to remove contaminants such as solids, organic pollutants, harmful microorganisms, and nutrients.

The process starts with screening to remove large particles, followed by settling tanks that separate heavier solids. The water then undergoes biological treatment, where microbes digest organic material. Finally, disinfection ensures the treated water meets environmental and safety standards.

By managing sewage responsibly, STPs help reduce pollution, preserve ecosystems, and support public health. Treated water can also be reused for non-potable purposes, like landscaping or cooling, promoting water conservation and sustainability.

Working of an STP Plant

• STPs follow a defined process to ensure safe water discharge or reuse:
• >> Preliminary Treatment: Screens remove large solids; grit chambers eliminate sand and fine particles.
• >> Primary Treatment: Solids settle at the bottom in tanks, separating them from partially cleaned water.
• >> Biological Treatment: Microbes break down dissolved organic matter in the water.
• Secondary Clarification: The resulting sludge is removed; cleaner water progresses to the next stage.
• >> Tertiary Treatment: Fine filtration and disinfection (UV or chlorine) polish the water and kill pathogens.
• >> Sludge Management: Collected sludge is dried or digested and safely disposed of or reused as fertilizer.
• Each stage ensures compliance with regulations while protecting the environment and conserving resources.

Our Approach to Your STP Needs

At Konark WaterDoc, we deliver end-to-end solutions based on a clear understanding of your plant's goals and challenges.

We begin with a detailed assessment of the wastewater quality, volume, and site specifics. Based on this, we suggest appropriate treatment methods that balance performance, cost-efficiency, and environmental responsibility.

We also conduct capacity forecasting to ensure your plant is future-ready. Throughout design and execution, we work collaboratively with you, ensuring the system aligns with your operational goals and compliance needs.

Types of STP Technologies We Offer

• Our STPs are built using diverse, scalable technologies suited for various industries:
• >> Activated Sludge Process (ASP) – Aerated tanks where microbes break down waste.
• >> Sequential Batch Reactor (SBR) – Treats water in controlled batches for flexible operations.
• >> Membrane Bioreactor (MBR) – Combines microbial treatment and membrane filtration for high-quality output.
• >> Moving Bed Biofilm Reactor (MBBR) – Plastic media supports biofilm growth for efficient treatment.
• >> Extended Aeration – Longer aeration for small to medium systems with stable loads.
• >> Rotating Biological Contactor (RBC) – Microorganisms on rotating discs break down pollutants.
• >> Trickling Filter – Wastewater passes over media colonized by microbes.
• >> Oxidation Ditch – A continuous loop system that ensures extended biological treatment.
• Each system offers specific advantages depending on budget, space, treatment goals, and effluent quality requirements.
