Sand Filtration and its Importance in an STP Plant


Sand Filtration


Everyone is well-versed with the term sewage treatment plant, which is a specially developed plant that has the role to treat the wastewater coming from various sources like commercial buildings, housing complexes as well as large housing societies. The wastewater that comes out from these said sources contains too much toxicity which if discharged untreated into the environment then they will cause huge trouble for both the environment as well as other human life. People often take it as a burden to set up a sewage treatment plant through a wastewater treatment plant manufacturer near them so that wastewater can be treated because they think that it is a tough process and also they do not give too much importance to it. Also, they don’t ever think about the water that can be saved through this plant rather than being dependent on alternative sources. Sewage treatment plants are readily available in the market and also our company representatives provide guidance throughout the process so that everything can be done in a smooth manner. We too provide discounts and various other offers with our plant which acts like value-added service at a very cheap rate.


As we all know the working of an STP plant is very simple and it includes various stages like primary treatment, secondary treatment along with tertiary treatment. Where the primary treatment includes the input of wastewater into the tank and which allows the heavier solids and organic matter to settle at the bottom through gravity. The second stage is the secondary treatment which eliminates the organic matter and other nutrients through various methods like the activated sludge process. Third and the final stage is the tertiary treatment which treats on the specific requirements for further purification through the process of disinfection, and filtration to remove the suspended solids, pathogens, and residual contaminants. And the best part is that these STPs can be installed at any place as it takes much less space in comparison to other companies and also they can be easily availed through sewage treatment plant manufacturers.

So till now, we have understood enough about the sewage treatment plant which can be easily installed through a STP Plant manufacturer and now is the time to understand the importance of sand filtration in a sewage treatment plant. Now, you might be thinking that what is sand filtration then let us tell you that sand filtration is a method of water treatment that allows the passage of water through the bed of sand in order to remove the impurities and particles. Below are mentioned some of the key importance of sand filtration in a sewage treatment plant:


Suspended Solid Removal - Suspended solids like organic waste, trash, and other particles are frequently present in sewage. These sediments in wastewater can be efficiently trapped and removed using sand filters, which helps to enhance the water's clarity and quality.


Bacteria and Pathogen Removal - The elimination of bacteria, viruses, and other pathogens contained in sewage can also be done by sand filters. The biological activities taking place inside the filter, along with the physical barrier of the sand bed, can assist lower the concentration of hazardous microbes, making the treated water safer for reuse or disposal.


Sedimentation and Settling- The settling and sedimentation of suspended particles can be done using sand filters. The turbidity of the water is decreased as the wastewater moves through the sand layer because heavier particles have a tendency to settle down. The removal of fine materials through sedimentation increases the effectiveness of following treatment procedures.


Nutrient Removal - Nutrients like nitrogen and phosphorus, which contribute to water pollution if discharged untreated, are needed to be removed frequently during sewage treatment. Through biological processes, sand filters can remove some nutrients. These nutrients can be converted or absorbed by microorganisms in the sand filter bed, which lowers their content in the treated water.


Pre-Treatment for further process - In sewage treatment plants, sand filtration is frequently employed as an initial stage of treatment. Sand filters help safeguard and improve the effectiveness of future treatment processes like biological treatment (activated sludge process) or disinfection (chlorination or UV treatment) by eliminating bigger solids and lowering the turbidity of wastewater.


Cost-Effectiveness - When compared to other cutting-edge treatment methods, sand filtration is a comparatively easy and affordable option. It is an efficient option for both large-scale sewage treatment plants and more compact decentralized systems since it requires less equipment and energy, so if you are thinking to install a STP then you can get in touch with the STP Plant Suppliers.
