In every power plant in the world, steam from water is the driving force. The quality is important to ensure efficient and reliable operation of the power plant equipment and to protect important and expensive assets.
X-Flow ultrafiltration (UF) tehcnology is developed to meet the challenges in the power generation industry. This is because of the importance of the pretreatment unit in the reverse osmosis (RO) membrane process for demineralized process water to feed the boiler and cooling water recycling. Those challenges are compounded by the need to deal with the more and more complicated contaminants found in raw water. Water losses must be minimized during processing while maximizing water recycling. These requirements are driven by the increasing awareness of water scarcity and on the subsequent regulations for water conservation and discharge.
The cooling water condenses the vapor out of the turbine. Because of the chemical dosing in the process, the water is exposed to the atmosphere allowing dirt and microorganisms to enter. The cooling water recycling has to face the following challenges:
It decreases the heat transfer efficiency and causes corrosions under deposit, which shortens the service life of the equipment.Corrosion: the corrosion caused by circulating water is mainly electrochemical corrosion. Contributing factors are equipment manufacturing defects, oxygen in the water, corrosive ions (Cl-, Fe2+, Cu2+), and microbial mucus slime. If the corrosion is not controlled, the heat exchanger and pipeline will be damaged in a short period.
The X-Flow brand offers a wide range of innovative technologies for Power Generation Industry. As effective tools for the pre-treatment of RO membrane for demineralization process, these solutions reduce the overall water footprint of plants, reduce downtime, and make plants operate more efficiently and at a lower cost.
This increases operation energy consumption and the maintenance frequency of the system. Those contaminants that can impact the performance and economical operation of downstream demineralization equipment can effectively and efficiently be removed by X-Flow ultrafiltration technology with excellent SDI control.
Seawater desalination requires extensive pretreatment expand the lifetime of the RO membranes and prevent the RO membranes from fouling and plugging with fine silt. X-Flow offers dedicated UF technologies specifically designed for seawater pretreatment to remove all fine silt and turbidity and screen microbiology. The UF technology provide a simple solution to produce water that meets the highest standards for SDI, turbidity and microbiology. X-Flow’s Seaguard and Seaflex membranes guarantee the best possible water to the desalination process in power plant boiler makeup water. OurHFS60 membrane is specially designed for silica removal.
