Engineering Nature-Based Water Treatment Solutions

Expert consulting in constructed wetlands, lagoon systems, and sustainable stormwater management

Engineering for the nature

About us

Phragmyra is a specialized environmental engineering consultancy dedicated to designing and implementing nature-based water treatment solutions. Our multidisciplinary team brings together deep field experience from numerous constructed wetland projects, including: Domestic wastewater treatment system, Agro-industrial applications and Integrated water reuse systems.

Phragmyra combines Phragmites, the common reed that serves as the foundation of constructed wetland systems, with Myra, derived from the ancient Greek « myron » meaning « sweet essence » or « pure fragrance. » Just as Phragmites transforms polluted water through its complex root systems and microbial partnerships, we engineer nature-based solutions that reveal the pure essence within contaminated water. The name embodies our core philosophy: harnessing the robust engineering principles of wetland plants to create elegant, sustainable treatment systems.

Core expertise

Constructed Wetlands Design

We design horizontal subsurface flow (HSSF), vertical flow (VF), and hybrid constructed wetland systems optimized for specific hydraulic loading rates and pollutant removal requirements.

Our engineering approach integrates biofilm kinetics modeling, substrate selection, and plant species optimization to achieve target effluent quality standards and regulatory compliance.

Each system is sized using advanced hydraulic modeling to ensure proper residence time distribution and treatment efficiency across varying seasonal conditions and flow variations.

Lagoon Systems Engineering

Our lagoon design expertise encompasses facultative, aerated, and anaerobic lagoon configurations with precise hydraulic and organic loading calculations based on climate-specific parameters.

We utilize computational fluid dynamics (CFD) modeling to optimize mixing patterns, oxygen transfer efficiency, and algae management strategies for consistent BOD and nutrient removal performance.

System design includes detailed thermal stratification analysis and sludge accumulation predictions to ensure long-term operational performance and maintenance scheduling requirements.

Stormwater Management

We engineer bioretention systems, constructed stormwater wetlands, and green infrastructure solutions using hydrologic modeling to meet specific runoff volume reduction and water quality improvement targets.

Our designs incorporate detailed soil media specifications, underdrain configurations, and vegetation selection based on local precipitation patterns and pollutant loading characteristics for optimal performance.

Each system includes overflow structures and monitoring provisions to ensure compliance with municipal stormwater regulations and long-term operational effectiveness under varying climate conditions.

Consulting and Support

We provide specialized technical support to nature-based water treatment companies including process optimization consulting, regulatory compliance assistance, and custom software development for treatment system modeling.

Our services encompass peer review of engineering designs, troubleshooting of underperforming systems, and development of proprietary calculation tools for sizing and performance prediction applications.

We also offer technical training programs and specialized database management solutions for performance monitoring and regulatory reporting across multiple treatment technologies and project scales.

Frequently Asked Questions

What are the main advantages of constructed wetlands over conventional treatment systems?

Constructed wetlands offer lower operational costs, reduced energy consumption, minimal maintenance requirements, and superior resilience to flow variations. They provide consistent treatment performance while creating valuable habitat and requiring no chemical additives for operation.

What treatment performance can we expect from constructed wetlands?

Our systems consistently achieve 85-95% BOD removal, 80-90% TSS removal, and significant nutrient reduction (70-85% nitrogen, 60-80% phosphorus) when properly designed and operated. Performance guarantees are provided based on specific influent characteristics and regulatory requirements.

In which regions do you specialize and operate?

While we provide consulting services across different continents, Phragmyra has developed specialized expertise and extensive experience in warm developing countries. Our deep understanding of tropical and subtropical climates, local regulations, and economic constraints enables us to deliver cost-effective solutions tailored to these challenging environments.
