A Case Study on STP at Trends Whispering Woods Apartment Bogadi, Mysuru

By selecting a traditional process for treatment of wastewater, you have made the right choice. Tremendous research has grown out of this tradition. The basis of this perfection the manufacturers offers is from operators who are responsible for its performance.

It is very essential to bear in mind that the desired volumes required in collection and reactors (aeration tanks) should hold minimum of one and half day’s capacity to perform. These sizes will guarantee the consortium of microbes to adapt to the unexpected environment. Most of these plants are designed similar to facilities that are often seen in the large treatment facilities including oil & grease removal. Small and medium plants treating domestic wastewater don’t require it. The consortium is capable of digesting these wastes.

At Trendz whispering woods, Mysuru, a sewage treatment facility was developed to initially treat 60 KLD and later enhanced to 120 KLD. Modules of bar screens, oil & grease trap and several aeration chambers to treat the wastewaters from the apartments were based on MBBR technology. These perform uninterrupted when engineered with the right quantity and choice of bioflm. Some of these technologies designed work wonders to perform with no human assistance.

Issues occurred as the manufacturers/suppliers of the plant changed operators. Very little treatment to wastewater was rendered as know how transfer was insufficient. You rely on operators who are committed to perform irrespective of who has supplied equipment to treat wastewater, with very little freedom to save expenditure. It is unlikely in the case of dissatisfaction operational expenditures are often redressed. All attempts to eradicate the deficiencies in the design to accommodate the consortium of microbes were a casualty.

This plant was finally referred to OxyO. The collection tank capacity was simply expanded to accommodate the whole day’s flow. The choice of biofilm was critical. A completely submerged biofilm having the same specific gravity of sludge helped develop a robust consortium of microbes in the collection tank to combat the pollutants. The ultimate objective is the same to apply massive active biomass for treatment. We have achieved it in the collection facility. This actually eliminates the need to design any further or separate operations.

Our solutions are unique and built to suit all customers. Our designs can be supplied to the end users who needs with no specialised skills to start their biological process plants. The aim is to minimise the struggle of operating the biological treatment plants. All our plants have operated without the need for any external help
for initiating microbial activity.
