Wastewater Treatment Plant for Small Communities

Introduction

Wastewater management is a tough issue for small communities to deal with. These areas often find it difficult to support conventional centralized wastewater treatment systems due to low economies of scale, lack of infrastructure and environmental concerns. Decentralized treatment plants, however, represent a cost-effective and efficient alternative that can help small communities find a better way to manage their wastewater. About Amalgam Biotech Amalgam Biotech is focussing in scalable and low-cost waste water purifying solutions targeted for villages,resorts and peri-urban clusters. In this blog, we’ll discuss the advantages of decentralized treatment systems and how the technology adopted by Amalgam Biotech is revolutionizing onsite wastewater management in rural communities.

Types of wastewater treatment plants available for small communities

The wastewater treatment of small communities does not have to be done by the same mammoth, costly facilities that service urban areas. Several customized strategies exist to efficiently and sustainably knit down the treatment of wastewater in relatively small, decentralized systems. Types of wastewater treatment plants normally used in small communities Below are the most frequently used types of wastewater treatment plants in small communities:

Packaged Treatment Units

packaged treatment units Pre-engineered, all-in-one system in containers intended for the treatment of small population (less than 5,000 people). Compartment systems are compact and quick to install and are very effective in decentralised edge of network or rural communities. NanoPlant, developed by Amalgam Biotech, is one such system and it is designed to give quality treatment in small communities. Typically, wastewater is processed by various mixed physical, biological, and chemical processes that are all combined in a single room. They are quick to deploy and have low operator skill requirements.

Constructed Wetlands

Constructed wetlands are a nature-based solution that relies upon plants, gravel beds and microorganisms to clean and treat wastewater. They are also ideal for eco-friendly regions where waste reduction is more than critical. Built marshes depend on natural processes to filter and purify the water, so they're an environmentally friendly choice. Plants (such as cattails, bulrushes, and reeds) are employed to absorb toxins and decompose organic wastes. It is possible to design such installations for small communities such as resorts or ecolibrium villages in a way that is beneficial for the local eco-system and sustainable.

Modular Bio-Towers

Modular bio-towers, such as those used by Amalgam Biotech in Pune’s Lonavala Hill Communities, offer a scalable solution for wastewater treatment. These are systems that are meant to be modular so that they can be scaled as the population increases, or with the increase in demand of treatment. Bio-towers employ state-of-the-art bio-filtering mechanism in order to achieve the treatment of the organic compound, nitrogen and phosphorus of waste water. It has been demonstrated that these systems deliver an 80% reduction in cost compared to traditional treatment processes. Versatile Cost: Effective Multi Cell Bio Tower The modular format of bio-towers enables use in villages and industrial house for low cost and effective treatment of sewage.

Emerging Technologies

Other technologies are being developed to meet changing wastewater treatment demands that are expected for small community treatment facilities. Some innovations to watch on the bottle include:

Solar-Powered Membrane Bioreactors (MBRs)

Solar MBRs can be considered as good choice for off-grid or rural regions. These systems combine physical/chemical treatment and membrane filtration to supply treated water to the highest specifications. Solar MBRs are self powered, as they operate on photovoltaic (PV) panels with no external electricity grid connection, which is ideal for remote areas with low electricity supply. These systems are efficient and effective in treating wastewater to a quality appropriate for reuse in agriculture or other nonpotable applications.

Anaerobic Baffled Reactors (ABRs)

ABRs (anaerobic baffled reactors) are a novel low-solids, low maintenance system. ABRs are especially well suited to small-scale and isolated communities as they treat significant quantities of wastewater with little operational input. These are considered biological treatment reactors and are characterized by multiple chambers which facilitate the degradation of organic material present in wastewater by means of anaerobic stages (in the absence of oxygen). The sludge from ABRs is minimal, hence easy to handle and there is no need for expensive sludge management. The treated water can be used for irrigation or to water landscaping, making it a valuable commodity for communities.

Phytoremediation Tanks

Phytoremediation is the technique that uses plants to filter and pinpoint contaminants in water. In phytoremediation tanks, plants like water hyacinths or duckweed are employed to soak up heavy metals and other water-borne pollutants from the surrounding water. These systems are low in cost and energy consumption, and, therefore, are suitable for small-population communities. Excellent for processing wastewater from farms or factory floor where pollutants like heavy metals are often left behind.

Advantages of decentralized wastewater treatment in small communities

Compared to centralized plants with large design, decentralized plants provide many benefits. Small communities with limited resources, such as ours, could benefit most from these advantages:

Cost-Effectiveness

Conventional ways of processing that waste can be costly to construct and operate — especially for small communities with limited coffers. De-centralized systems (e.g., package treatment units, or modular bio-towers) are generally less costly to install and to operate. They are cheaper in terms of both capital and operating costs, and as such are suitable for certain rural or peri-urban regions. Furthermore, the small size of the decentralized systems make them adaptable to the conditions of a given community, and allow the appropriate treatment performance to be achieved without wasting any resources.

Sustainability

Sustainable practices low the overall effect on the environment for decentralized wastewater treatment systems. Natural treatment, such as systems like constructed wetland or phytoremediation tanks, are based on the use of natural processes to treat wastewater, which means that there is fewer chemicals and energy used. In addition, several decentralized systems are equipped for re-sale and recycling of water, all of which supports water saving in water-scarce areas.

Flexibility and Scalability

Centralization on one hand is gubby but decrearization umboric. This is one of the most important benefits of any deentralired order. As communities and needs expand and/or change, their wastewater treatment system can be “scaled up” to serve new demands. A modular plant like a bio-tower or a packaged treatment unit can be added to, or retrofitted, to come up with a future-proof design for the community at large.

Rapid Deployment

Small community decentralized systems can be implemented rapidly and are well-suited for regions requiring rapid interventions. Packaged units and skid mounted treatment trailers may be installed and made operational in just a matter of days, small communities from inedible water.

Trends in the Development of Small Communities Wastewater Collection and Treatment Systems

With a number of trends on the horizon that only stand to improve the efficiency and sustainability of decentralized systems, the future of wastewater treatment for small towns and communities looks promising:

Pay-As-You-Treat Modelssome

Communites may transition to "pay-as-you-treat" systems combining modular treatment units which can be leased and charged by the gallon of water treated. This design offers a simple and low-cost solution to the decentralised treatment of the domestic effluent, without the need for a large initial investment in infrastructure. Companies such as Amalgam Biotech are already investigating such models in order to provide small communities with the means to treat wastewater.

Mobile Treatment Units

Mobile treatment trailers are also gaining traction in small communities. These plants are conceived for an emergency stand-by from disaster areas or for a temporary waste water treatment. Mobile systems are small and can be easily deployed for waste water treatment, supplying safe and clean water in emergency relief situations.

Blockchain Water Credits

Blockchain could be used to one day treat wastewater. Credit and reward Proposals Communities that reach certain targets for wastewater treatment or water reuse might be given blockchain based water credits that can be traded in or cashed in for monetary rewards and incentives. This system motivates communities to become more sustainable and rewards all who help conserve resources.

Conclusion

How do small communities handle wastewater treatment? With the implementation of decentralized treatment technologies (package plants, modular bio-towers, constructed wetlands) small populations may effectively treat their sewage at a low cost budget and low environmental impact.
