Today’s power industry is already subject to strict official regulations. These rules will only become more stringent in the future. As a result, environmentally friendly, cost-effective solutions that ensure plant and operational safety are in high demand.
The process of electricity generation from fossil fuels such as coal, oil and natural gas is water-intensive. Between 40-50% of all water abstracted and used in developed countries is used in the generation of electricity. Thus, a reliable, abundant and predictable source of raw water supply to a power plant is a critical factor in site selection. Water supplies are required to provide various process waters for the following essential main purposes such as make-up water, cooling water for steam turbine condensers,...
Chlorine dioxide is a significant product in the control of algae, planktonic and sessile bacteria, bio-film and scale in power plants, cooling towers, loops and cooling systems. CleanOxide helps maintain the efficiency of heat exchanger surfaces, reservoir intakes and ancillary equipment. Traditional oxidising agents such as chlorine and bromine, on the other hand, are associated with pH constraints and corrosion problems.
Use natural air currents for aerobic sewage treatment via venting pipes.
Alternatively, they can be solar powered using a very low energy 12 Volt fan.
The FILTERPOD requires no electricity for the treatment process. They finally allow modern, high quality sewage treatment for all regions of the world, even for off-grid locations.
Fossil fuel or solar-thermal power plants require clean water for their operation. Water used may contain several impurities such as calcium, magnesium or silica which can cause damages to turbines or heat exchangers. For this reason, water must be treated by ionic exchange or mechanical filtration. Also, the appropriate wastewater treatment for its reuse through sand filters in order to contribute to a sustainable water use is of vital importance.
With the demand for power reaching new highs, large power plants are being constructed at an incredible rate. In the years to come, these new plants, along with existing facilities, will be relied upon to meet the needs of a continually growing population.
The Fractional Electrodeionization (FEDI) process is an advancement of conventional EDI. The patented dual voltage process allows for a higher flexibility and tolerance to inlet water conditions, thus lowering the risk of scaling, and improving the plant& design economics and reliability. By incorporating a two-stage separation process with different voltages the FEDI process is able to: Achieve a higher hardness tolerance by having distinctly different concentrate chambers with separate reject streams and thus...
We offer a complete line of solutions as follow: Desalination by reverse osmosis, brackish water reverse osmosis, multimedia filters, feed pump & feed pump skids, EDI, pre & post treatment options, membranes, softners, services & maintenance.
KISTERS solutions provide powerful data management capabilities for water/wastewater treatment plant operators. Easily interfaced to existing SCADA and telemetry systems, KISTERS solutions provide superior graphical and tabular editing and reporting capabilities for your process data. KISTERS solutions are a “future proof” choice for your data historian.
QUA’s FEDI® (Fractional EDI) stacks have superior hardness tolerance compared to the other EDI products on the market. With a dual voltage process this allows for a higher flexibility and tolerance to inlet water conditions, thus lowering the risk of scaling, and improving the plant's design economics and reliability. FEDI stacks are available in three different models which can be applied either for higher hardness tolerance or high water flow rates.
MEGA FEDI stacks are ideal for large capacity, high flow...
The fresh water requirement for a cooling tower in a typical coal-based power plant is approximately 80% of the total consumption of water. These concentrated cooling water blowdown streams are extremely rich in silica, are characterized by higher hardness levels and include other organic loads. Aquatech has vast experience in recycle/reuse solutions for cooling tower blowdown and cooling tower water treatment.
Water is one of the single biggest raw materials used in meat processing, and its quality is of great importance to prevent contamination of food product. The use of contaminated water in the processing plant can spread infection across the whole food batch. This is a cause of serious concern to the food industry, consumers and regulatory bodies, besides that, it causes financial losses and food scare. Chlorine dioxide, a very powerful biocide, has a number of advantages over other products commonly used in the...
Sulfide Odor Control
Sulfide is found throughout the environment as a result of both natural and industrial processes. Most sulfide found in nature was produced biologically (under anaerobic conditions) and occurs as free hydrogen sulfide (H2S) - characterized by its rotten egg odor. We are most likely to encounter biogenic H2S in sour groundwaters, swamps and marshes, natural gas deposits, and sewage collection/treatment systems. Manmade sources of H2S typically occur as a result of natural materials containing...
Cities and towns are often responsible for maintaining critical assets such as water and wastewater treatment facilities and power generation plants. Oil analysis on this critical equipment as part of a robust maintenance program is a very cost effective way of failure avoidance. Additionally, greater emphasis on environmental conservation and a focus on delivering critical services while operating under reduced budgets leads municipalities to activate these programs. Spectro oil analysis solutions are...
FGD is Key to Coal-Fired Power Generation: Wet Flue Gas Desulfurization (FGD) is a process by which coal-fired power plants remove sulphur dioxide (SO2) before emitting their flue gas into the atmosphere. The water intensive scrubbing process requires a durable treatment technology as FGD blowdown wastewaters are highly contaminanted.
