The Goal is written by the Eliyahu M. Goldratt which explains the methods for optimization of the work environment with respect to the company’s goal. The Theory of Constraints focuses on the utilization of the bottleneck machine or machines. In this book bottleneck impedes company’s goal A bottleneck is a resource which is determined when it equals to or less than the market demand placed on it. In other words‚ total capacity or maximum output are blocked by the bottleneck. In the book‚ there are

but it is also vital for sanitation and irrigation. Wastewater treatment facilities were designed to treat the outflow before entering the receiving waterways. The ideal modern system collects storm water separately from wastewater and treats it to remove all pollution‚ but that has become a difficult task. There are four different types of wastewater pollutants and all four are treated before being released. The primary treatment in removing pollutants from wastewater is the removal of the
