We offer practical solutions built on engineering, proven data and real-world success.

two types of wastewater treatment plants

CLEAN WATER SYSTEMS BUILT TO LAST — ULTRA-LOW ENERGY, FAST TO DEPLOY, EASY TO MAINTAIN.

WHAT WE DELIVER IN WASTEWATER PROJECT

From concept to commissioning — our team covers every step to build reliable wastewater treatment systems.

We design systems based on actual load, site conditions and future growth.

Modular units are pre-fabricated for fast deployment and minimal civil work.

Our specialists handle installation, integration and performance validation on-site.

We provide technical support, optimisation and training long after handover.

project output

Simple, Smart and Scalable Deployment

We deliver treatment plants through a proven model — fast setup, low risk, full control.

01.

Assess & Scope

We analyse load, compliance, and environment to define the right system.

02.

Fabricate & Install

Modular units are pre-built off-site and installed with minimal disruption.

03.

Commission & Optimise

We ensure the plant runs efficiently and provide post-installation support.

04.

AUTOMATE & MONITOR

AI and smart cameras run the plant — no daily staff needed.

modular wastewater treatment plants

“Fast to Deploy, Easy to Scale, Built for Remote Sites”

Modular plants are compact, factory-built systems that offer quick setup, low energy use and scalable capacity. Each unit treats up to 40 m³/day, with systems expandable to 240 m³/day, serving up to 12,000 people daily. Ideal for rural areas, temporary setups or fast-track infrastructure.

“Engineered for Scale, Built to Last with Reinforced Concrete Precision”

Our concrete plants are designed to handle large-scale urban wastewater demands with long-term durability. Built from reinforced concrete and modular components, these systems manage from 500 m³/day up to 50,000 m³/day, supporting populations of up to 2 million. They deliver high capacity, low energy usage and exceptional performance.

Traditional Fertilizers

ESSENTIAL NUTRIENTS FOR EVERY FIELD

From nitrogen-rich formulas to balanced NPK blends, our fertilisers are crafted to meet the needs of your soil and crop at every growth stage.

NITROGEN-BASED FERTILISERS

Urea, Ammonium Nitrate and Ammonium Sulfate supply fast and efficient nitrogen to support strong vegetative growth across crops like maize, rice and wheat.

PHOSPHORUS-BASED FERTILISERS

DAP and MAP are essential for early-stage development and root formation, especially effective in acidic or alkaline soils depending on the crop.

NPK BLENDED
FERTILISERS

Custom NPK blends like 15-15-15 or 20-10-10 deliver balanced nutrition enhanced with micronutrients, tailored to local soil tests and specific crop needs.

frequently asked questions (faq)

We are servicing in more than 100 countries

Operational costs: $0.10 per m³ (includes energy, labor, sludge disposal, and maintenance).

Yes. Sludge can be repurposed as:
•  Biosolid fertilizer: Requires compliance with heavy metal limits
    (e.g., Cd, Pb, Hg).
•  Soil amendment: Enhances soil structure and nutrient
    content.
•  Energy production: Via biogas from anaerobic digestion.

Full treatment energy use: 0.2 kWh/m³ — from intake to final discharge.

Our technology requires minimal amount of chemical usage:

  • Coagulants (e.g., ferric sulfate [Fe₂(SO₄)₃], aluminum sulfate [Al₂(SO₄)₃]) for phosphorus removal.
  • Disinfectants (e.g., chlorine, UV irradiation) if tertiary treatment is required.

We offer chemical, organic, compound, and specialty fertilisers suitable for a wide range of crops.

Yes, Saver+ is designed to enhance the efficiency of chemical fertilisers without changing your existing application methods.
