What are small Sewage Treatment Plants?
Small Sewage treatment plants are those that fall under the category of 1 KLD to 250 KLD. EcoTec provides fully automatic systems that can be placed in underground tanks or even in existing septic tanks. The treated water from these plants beat the threshold set by government by a very high degree. The operation and maintenance of these plants are very low when compared to the expense of running a STP from where sewage is taken out in trucks regularly and sometimes even daily. For example the operation charge for a EcoTec STP system in a 50 apartment building is only 150 Rs/ day and there is no need for an operator. The treated water can be used for flushing after disinfection.
What advantages make SBR more reliable choice of technology?
SBR plants are usually automated and are less dependent on operators in small sewage treatment plants. In a batch process like SBR water is filled into the reactor and processed for a longer period of time until it is fully treated and then let out once the batch of water is treated. EcoTec SBR works in 4 batches in a day during normal operation and with lesser cycles when there is less sewage output. On the other hand continuous processes struggle when there are load and flow fluctuations.
How does SBR system take care of low occupancy and low load in sewage?
Our intelligent sensing system in our advanced plants can detect the low flow conditions and adjust the treatment to the low inflow automatically. If there is a continous low load conditions the program can be revised for low flow. Both work the same in saving energy and yet providing required treatment maintaining the MLSS necessary for the treatment process.
How does one know when to carry out maintenance or service of the plant?
Each plant has its own service and maintenance plan programmed in the controller. When the time for service and maintenance is nearing, the plants send alarm for service and maintenance respectively. You have to call the professional for service of the plant based on the warning message.
