  • Demin water

    Demin water

    The main concerns in power generation are the availability, reliability and life cycle of internal systems. Water quality in terms of electrical conductivity, silica, and other solids concentration is of critical importance in maintaining efficient operation of various internal systems in limiting downtimes due to corrosion or preventative maintenance.

    The raw water from any type of source contains suspended, dissolved solids and other contaminants which need to be treated prior being fed into the process.

    Demineralization by GES systems is a proven process, successfully implemented in power plants worldwide.

    We offer a complete solution starting with pre-treatment for removing suspended solids, following by desalination and ending with final polishing for reaching extremely high purity.

  • Cooling tower make up water

    Cooling tower make up water

    A key parameter used to evaluate cooling tower operation efficiency is “cycles of concentration”.

    This is calculated as the ratio of the concentration of dissolved solids in the blow-down water compared to the make-up water and is also approximately equal to the ratio of the volume of make-up to blow-down water.

    It is desired to maximize the cycles of concentration, which will minimize the blow-down water quantity and will reduce the make-up water demand. The actual number of concentration cycles depends mainly on the make-up water quality.

    GES offers tailor made solution for cooling towers make-up water treatment. Our process design is based on vast experience and most advanced process design approaches.

    Our solution will maximize the number of concentration cycles of the cooling towers and will consequently provide the customer with significant cost reduction in both CAPEX and OPEX aspects.

  • Gas turbine / Boiler make up water

    Gas turbine / Boiler make up water

    For gas turbines and boilers, the high purity of feed water is required to ensure proper operation of steam generation systems.

    High purity feed water reduces the scale buildup, the corrosion rate and therefore the use of chemicals for the internal treatment. Moreover, it causes less frequent blowdown which results in lower fuel costs.

    GES advanced membrane processes create an opportunity to treat feed water streams to meet stricter system performance for industrial boilers and gas turbines on one hand and to ensure cost effective and stable performance on another.

    Our treatment system uses various of advanced technologies, such as UF, O, and EDI to treat raw water and to generate a permeate stream that meets boiler feed water criteria. The product of final polishing by electro deionization is of the highest quality in terms of concentrations of suspended and dissolved solids, silica, and hardness.

  • Blow down treatment

    Blow down treatment

    During the operation of the cooling tower or turbine, the dissolved solids present in a makeup water are concentrated as a result of evaporation water loss.

    To maintain total dissolved solids below allowable limits, a controlled amount is sometimes bled off. This volume, called boiler blowdown, is defined as wastewater and is replaced with high-purity make-up water

    As wastewater discharge regulations become more stringent, power plants and other industrial sites are looking for ways to reduce makeup water requirements and to recycle and reuse saturated wastewater such as blowdown streams for further reuse in the plant.

    GES offers its clients with a complete solution for all blowdown stream treatment and reuse at the highest recovery rate possible to ensure the compliance with the discharge regulation and reducing the operational costs related to a feed water price and disposal costs.
