Sewage treatment plants using plantation technology, also known as Constructed Wetlands or Botanical STPs, treat sewage through the combined action of specially selected plants, soil, bacteria, and micro-organisms. These systems mimic natural wetlands, with plant roots and associated microflora removing pollutants naturally and efficiently.

Technology and Process

• Wastewater passes through a series of beds or basins planted with wetland species like sedge, grasses, and reeds.

• The roots provide a large surface for beneficial bacteria to colonize, supporting the breakdown of organic matter and absorption of nutrients and pollutants.

• Plants uptake certain contaminants and help sequester them in their biomass, while the root zones promote aerobic and anaerobic degradation.

• The system is low-maintenance, energy-efficient, and blends well into landscapes.

• Suitable for domestic, institutional, and small-scale industrial sewage, and can be enhanced with other treatment stages for larger flows.

Advantages

• Lower energy consumption compared to conventional mechanical STPs.

• Minimal odor and reduced operational costs.

• Treated water is suitable for landscape irrigation or safe surface discharge.

• Creates green, eco-friendly sites that can educate and raise awareness.

Applications in India

• Used for housing complexes, hospitals, resorts, factories, and rural projects.

• Neptune Technologies and similar companies offer "Sewage Treatment Plant - Through Plantation" systems designed for industrial and community use, priced competitively with traditional STP systems.

Sewage treatment through plantation is an innovative ecological method, ideal for projects focused on sustainability, landscaping, and low operational costs while meeting environmental standards.

A 20 KLD Sewage Treatment Plant (STP) is a compact, efficient, and fully engineered wastewater treatment system designed to treat up to 20, 000 litres of domestic sewage per day. It is ideal for small hotels, residential complexes, schools, hostels, commercial buildings, clinics, and small industries where space is limited and reliable wastewater treatment is essential. The plant ensures compliance with pollution control board norms and helps users reuse treated water for gardening, flushing, and general utility applications.

The STP typically incorporates primary, secondary, and tertiary treatment processes within a compact footprint. Sewage first passes through screening and grit removal units that eliminate large particles and oil/grease content. The equalization tank stabilizes flow variations, ensuring uniform loading to the biological system. The biological treatment is carried out using either the MBBR (Moving Bed Biofilm Reactor) or Extended Aeration ASP technology. Both processes effectively reduce organic load (BOD/COD) by supporting active microbial growth and maintaining adequate dissolved oxygen levels through fine-bubble aeration systems.

After biological treatment, wastewater flows to a secondary clarifier, where suspended solids and biomass are settled and returned to the aeration tank for process stability. The clarified water then undergoes tertiary polishing through a Multimedia Filter or Activated Carbon Filter, followed by disinfection using Chlorination or UV treatment. This ensures high-quality treated water suitable for safe discharge or onsite reuse, helping conserve fresh water and reduce environmental impact.

The 20 KLD STP is supplied as a pre-fabricated, easy-to-install system with pumps, blowers, piping, valves, instrumentation, and an electrical control panel.

Ozone Water Treatment Plants use ozone (O3), a powerful oxidizing agent, to purify water by oxidizing and decomposing contaminants such as bacteria, viruses, organic compounds, and metals like iron and manganese.

How Ozone Water Treatment Works:

• Ozone is generated on-site by electrical discharge (corona discharge) or ultraviolet (UV) light, which splits oxygen molecules (O2) into atomic oxygen that recombines to form ozone (O3).

• The ozone gas is injected into water using systems like venturi injectors or diffusion bubbles, where it dissolves rapidly.

• Once dissolved, ozone oxidizes bacteria and organic/material contaminants, rupturing cell membranes and breaking down complex molecules.

• It converts metals such as iron and manganese into solid oxides, which can be filtered out easily.

• Following oxidation, remaining ozone decomposes back to oxygen, leaving no harmful residues.

• Contact time, ozone dose, and mixing efficiency are critical to maximize treatment efficacy.

• Ozone treatment often complements other filtration and disinfection methods like UV and activated carbon filters.

Applications:

• Municipal drinking water disinfection.

• Industrial wastewater treatment for removing odors, colors, and toxic substances.

• Food and beverage processing water purification.

• Aquaculture water treatment.

• Ballast water treatment on ships.

Advantages of Ozone Water Treatment:

• Extremely strong and fast oxidant, more effective than chlorine.

• Broad-spectrum antimicrobial action without chemical residues.
