Hydrossis Sewage Treatment Process

The Hydrossis Sewage Treatment Process was developed by HWT to provide reliable, energy-efficient sewage treatment for sites where consistent compliance with discharge standards is required. By combining the proven principles of the Modified Ludzack-Ettinger (MLE) process with the flexibility of a Sequencing Batch Reactor (SBR), a treatment system has been created that delivers excellent performance while maintaining operational simplicity. The process is inspired by the remarkable bacterial communities that naturally remove pollutants from wastewater.

Why the Hydrossis Sewage Treatment Process Works

Biological sewage treatment relies on microorganisms to break down dissolved organic matter and nitrogen compounds. In nature, these biological reactions occur slowly and continuously. Consequently, treatment systems perform best when conditions are carefully controlled and sufficient time is provided for biological activity.

The Hydrossis Process has been designed around this principle. Aerobic and anoxic treatment conditions are provided within a carefully managed operating cycle. As a result, organic pollutants are reduced efficiently while nitrogen removal is enhanced. Furthermore, energy consumption is minimized because aeration is only provided when required.

Combining the Advantages of MLE and SBR Technology

The Modified Ludzack-Ettinger process has long been recognised as an effective method for biological nutrient removal. Similarly, SBR technology has been widely adopted because treatment, settling and decanting can be achieved within a compact footprint. By combining these technologies, the Hydrossis Process benefits from both proven nitrogen removal and flexible batch operation.

In addition, the process can be adapted to suit a variety of applications. Whether a remote lodge, office development, school, labour camp or industrial facility is being serviced, the system can be configured to match the required treatment objective.

Designed for General Limit Compliance

Many sewage treatment plants are required to achieve General Limit discharge standards. The Hydrossis Process has been specifically developed for these applications. Through careful control of aeration, mixing and settling cycles, high-quality treated effluent can be produced on a consistent basis. As a result, treated water can often be reused for irrigation, dust suppression and toilet flushing, depending on local requirements.

Moreover, modern process control systems are incorporated to improve reliability and reduce operator intervention. Therefore, dependable operation can be achieved even at remote installations.

A Practical and Energy-Efficient Solution

The Hydrossis Process is not intended to be a one-size-fits-all solution. Instead, it has been engineered for applications where robust biological treatment, nutrient removal and operational efficiency are required. By combining established treatment principles with modern automation, a sewage treatment process has been created that delivers excellent performance while keeping operating costs under control.

For projects requiring dependable General Limit sewage treatment, the Hydrossis Sewage Treatment Process provides a proven and practical solution.
