SMART AND SUSTAINABLE BIOLOGICAL WASTEWATER TREATMENT: A TRANSFORMATIVE SOLUTION FOR CLEAN WATER AND LOWER COSTS
At WaterNext, we specialize in delivering high-efficiency and eco-friendly biological wastewater treatment systemsthat combine nature-based processes with smart engineering. Our goal is to provide industries and communities with reliable, low-cost solutions that ensure clean, reusable water while supporting sustainability and regulatory compliance.
Biological wastewater treatment uses activated sludge, a rich blend of microorganisms such as bacteria, protozoa, amoebae, and rotifers. These microorganisms work together to form flocs that play a central role in the purification process. This natural, biological approach to wastewater treatment has proven to be not only highly effective but also economically and environmentally advantageous.
HOW DOES THE ACTIVATED SLUDGE PROCESS WORK?
The activated sludge process relies on a population of suspended microorganisms that feed on biodegradable organic matter in wastewater. As these organisms metabolize contaminants, they convert them into smaller, less harmful compounds, such as carbon dioxide, water, and new microbial cells. Over time, the biological flocs grow in size and settle easily, allowing for efficient separation of clean water from the biomass.
This microbial community is sustained in an aeration tank, where optimal oxygen levels are maintained to support bacterial growth and contaminant breakdown.
THE CRITICAL ROLE OF OXYGEN IN BIOLOGICAL TREATMENT
Oxygen is a vital component of the aerobic biological treatment process. The presence of dissolved oxygen enables bacteria and other beneficial microorganisms to thrive. It fuels the biochemical reactions that break down organic pollutants and promotes the reproduction of active biomass. Without sufficient oxygen, treatment efficiency drops, and the microbial balance is disrupted.
That’s why our systems are engineered to ensure continuous aeration, stable oxygen levels, and optimal biological performance.
WHY CHOOSE 100% BIOLOGICAL WASTEWATER TREATMENT?
Unlike traditional chemical-based methods, 100% biological wastewater treatment systems offer a cleaner, greener, and more cost-effective approach. Here are the key benefits of going fully biological:
💧 Low operational costs: with operating costs as low as €0.10 per cubic meter, biological systems drastically reduce the need for costly chemicals and energy-intensive processes.
💧 Eco-friendly and sustainable: this process supports natural cycles and eliminates chemical discharge, contributing to a reduced environmental footprint and better alignment with sustainability goals.
💧 Minimal maintenance: automated controls and self-regulating microbial processes ensure reliable performance with limited operator involvement.
💧 Extremely low sludge production: compared to traditional systems, biological treatment produces significantly less sludge—and the sludge generated is non-toxic and easier to manage.
💧 High removal efficiency: biological systems are effective at removing COD (Chemical Oxygen Demand), BOD (Biochemical Oxygen Demand), TSS (Total Suspended Solids), nutrients, and other contaminants, resulting in crystal-clear effluent.
💧 Water ready for reuse or discharge: treated water meets high-quality standards and is suitable for irrigation, industrial reuse, or safe discharge into the environment.
A SMART INVESTMENT IN SUSTAINABILITY AND LONG-TERM EFFICIENCY
A 100% biological wastewater treatment system is more than just an operational upgrade—it’s a transformative step toward smarter, more responsible water management. These systems are ideal for a wide variety of applications, including:
- Industrial wastewater treatment (e.g., food & beverage, textiles, chemicals)
- Municipal and urban wastewater facilities
- Commercial and hospitality complexes
- Remote or decentralized communities seeking autonomous solutions
By adopting biological treatment, operators can reduce their dependency on chemicals, improve effluent quality, and simplify regulatory compliance. At the same time, they reduce carbon footprint, lower sludge disposal costs, and contribute to water reuse strategies.
