Due to years of margin erosion, some of which was certainly warranted, a major consolidation has occurred during the last several years. Additionally, they have started to charge for many of the services that were once part of their bundled offering. Clearly this consolidation is not benefiting the end user of these products. In summary, it is clear that these exchanges will continue due to the momentum and venture capital money behind them. However, if their basic business model does not change, increasing value to suppliers and customers alike, suppliers will suffer in the short term, and the entire industry will in the long run.

The tank is adjusted for pH followed by addition of hydrogen peroxide and discharged. A vertical concrete tank works as the anaerobic reactor. Influent having near neutral pH enters at the bottom, passes through the activated sludge blanket having anaerobic bacteria, the bacteria decompose the incoming sludge, methane gets released and water overflows through top of the reactor. Under normal operating condition the sludge blanket remains suspended in reactor. However in case of influent having high COD, the gas generation is heavy and it disturbs the sludge blanket, making it rise to the top and get washed out along with the overflow there by destabilising the system.
