How does a sewage treatment plant operate?
In our rapidly growing urban landscapes, the management of wastewater has become an increasingly critical concern. As councils and industries seek sustainable solutions, sewage treatment plants emerge as vital players in ensuring the responsible and efficient handling of sewage.
At its core, a sewage treatment plant is designed to treat wastewater generated from residential, commercial, and industrial sources. The process involves removing impurities and contaminants to produce treated effluent that can be safely released into a ditch or watercourse. A well-designed system contributes not only to environmental conservation but also to public health.
The process at Binder includes the following steps:
1. Collection and Inflow:
The first step involves the collection of raw sewage from various sources through a network of underground pipes. The sewage is then transported to the treatment plant, where it undergoes a series of processes so it is transformed into effluent that can be safely discharged.
2. Screening and Primary Treatment:
Upon arrival at the treatment plant, the raw sewage undergoes a screening process. Following this, the primary treatment phase involves the separation of solid and liquids in sedimentation tanks, gravity allows the heavier solids to settle, forming sludge, while the relatively clearer effluent is ready for processing.
3. Secondary Treatment:
The next stage focuses on primary treatment, this is often achieved through biological processes, where microorganisms break down the organic pollutants. Methods used include activated sludge processes, trickling filters, and rotating biological contactors.
4. Tertiary Treatment:
In some cases, a tertiary treatment phase may be employed to further refine the treated effluent. This stage aims to remove the remaining contaminants, to meet specific effluent quality standards set by the Environment Agency.
5. Sludge Management:
The sludge produced during the treatment process is not discarded. Instead, it undergoes further treatment, such as anaerobic digestion or mechanical dewatering, to reduce its volume and convert it into biosolids. These biosolids can be repurposed as fertilisers for agricultural use or disposed of in an environmentally friendly manner.
