Water Treatment Introduction

In the steam boiler power plant or industry, high purity feed water is required to ensure proper operation of steam generation systems. High purity feed water reduces the use of boiler chemicals. Scale buildup is reduced due to a smaller concentration of impurities in the boiler feed water to foul heat transfer surfaces. The lower level of impurities also reduces corrosion rates in the boiler.

When a boiler is used to run a steam turbine, turbine blade erosion is reduced due to higher purity steam generated. Silicate, particulate matter, suspended solids, total organic carbon (TOC)  and colloidal deposits decrease boiler efficiency and also result in premature failure of turbines.

By Raw Water Treatment Plant, that impurities can be removed or decreased so turbine and boiler efficiency can be maintained. Here is the simple diagram of water treatment position:
