Material removed from sewage by the fine screen is most frequently:

The material removed from sewage by the fine screen is most frequently ground up and returned to the sewage. This process is often referred to as "grit removal," and it is critical in the treatment of wastewater. Fine screens are designed to capture smaller particles and solids that can interfere with the treatment process. By grinding this material, it can be reduced to a smaller size, which allows it to be reintroduced into the sewage stream for further treatment rather than being discarded as waste. This not only helps maintain the efficiency of the treatment processes but also minimizes the loss of organic matter that could otherwise contribute to the treatment process.

The other methods of dealing with screened material, such as blowing it to a grit storage tank, burning it as fuel, or drying it for disposal at sea, are less common practices for the output from fine screens. Typically, the focus is on maximizing the treatment efficiency and utilizing all possible organic matter within the sewage system, making the approach of grinding and returning material to ongoing processes the standard practice in sewage treatment facilities.
