Optimizing Cooling Tower & Waste Water Filtration
Are you having corrosion or rust issues with your current housings?
The better choice are stainless steel bag housings,
but at the cost-effective prices of carbon steel.
Cooling Tower & Waste Water Filtration
Cooling water whether used in comfort cooling (air conditioning) or industrial cooling water is vital to many processes. Open recirculating cooling towers, act as air washers and pick up any air-born debris, they are utilized to conserve water by its re-use in a cooling tower. The water is diffused into small droplets and evaporative cooling decreases the water temperature. This process requires a high volume of outside air forced through the cooling tower via a fan to initiate evaporative cooling in the tower.
The cooling tower with the outside air flowing over it not only cools the tower water but also acts as an air cleaner. Anything in the air ends up in the cooling tower water. Cooling tower water filtration is just one of the industries that implement both filter bag housings and filter media to ensure a water filtering process that is safe and effective; whether they are used for an industrial site or air-conditioning in a building, the water treatment can make a large impact on their overall operations.
Filter bag housings paired with their bag filter media make it possible for efficient cooling water filtration, just one of the many industries we serve here at Filter Sciences.
Many types of filtration require backwash and loss of vast amounts of water when the whole purpose of the cooling tower is water conservation. Bag filtration requires no regeneration, it is truly zero water discharge. The bags filled with particulate are simply removed and cleaned or discarded. A second great advantage is the level of filtration can be altered by simply changing to a different type of bag. Even if you have another type of filtration system in use, such as a sand filter, which regenerates and wastes a large volume of water our system can be utilized to filter the regenerate and recycle it back into the system.
When facilities opt for cooling towers as a part of their system, some variation is needed to establish effective and efficient water filtration processes and system longevity. When neglected, cooling tower water is subjected to organic growth, scaling, corrosion, and fouling — all of which cost time in money as employee and plant productivity is reduced. So, how do you avoid facility downtime and costly equipment replacements? You use high-quality stainless steel filter bag housings and optimal filter media for your operation.
What is cooling tower water filtration?
Cooling tower water filtration is a set of technologies that filter potentially harmful debris and particles from your cooling tower feed water to reduce bleed off and filter the process water. Each system varies some, but the specific configuration depends on the following:
- The nature of your cooling tower
- Closed-loop, once-through, or open circulating
- The water quality
- The makeup and chemistry of your water
- The option of your bleed off water being treated for reuse
- Circulating concentration
- The type of heat exchanger
What are the components of a basic cooling tower water filtration system?
The variations you will observe in cooling water filtration will come from the chemistry of your circulatory water and the quality of feed water. A basic system implements the following:
- Inhibitor feed
- Biocide
- Automated monitoring
- Filtration and/or ultrafiltration
- Ion softening and/or exchange
Because each facility will have a different water quality, the filtration process will use a combination of the above methods which is why it is critical to talk with a water filtration specialist to find the optimal system for your business.
What does the cooling tower water filtration manage?
There are many elements of the filtration system, and it typically controls levels such as:
- Iron
- Organic matter (microorganisms which lead to corrosion)
- Air-borne Particulate pulled into the tower water
- Total suspended solids (TSS)
While there are many steps in industrial cooling water filtration including the water uptake, ion exchange and water softening, chemical treatment, and bleed off, as well as biocide treatment, we will go more into depth on filtration, ultrafiltration, and side-stream filtration.
- Filtration and ultrafiltration - Running cooling tower water through filtration helps remove any debris or suspended particles such as organic matter and sediment. It is important to tackle this step early to remove any solids that may escape upstream that can cause fouling later on down the line. Depending on the type of filter media and filter bag housing being used, particles can be removed to under one micron.
- Side-stream filtration - If your cooling water tower system processes and recirculates water, a side-streamed unit is helpful to control for drift contamination. If your system requires side-stream filtration, it is a good idea to consider a multimedia filtration system.
Filtering water in a cooling water filtration system is advantageous in keeping your equipment clean, efficient, effective, and corrosion-free.
Waste Water Filtration
Historically, industrial water and wastewater solids filtration has been conducted using filter cartridges. However, improved technology and superior bag options have allowed bag filter bag housing units to do the job at a much lower cost and higher flows.
Industrial Process Water - Filtration systems are essential in the treatment of industrial process water including wash water and cooling water before it is reused or disposed of. Fragments of what was cooled — metal, plastic, rubber or any other particulate— that are present will be left behind if an effective filter bag housing unit is used.
Wastewater Filtration - Wastewater from municipal, commercial, and industrial sources must be treated and filtered prior to being reused or disposed of. Filter bag housing systems help to rid the water of harmful contaminants before being disposed of or recycled. Particulates that are removed include sand, grease, oil, and other solid particulates.
Agricultural Water - Water that is used for agricultural processes faces some unique challenges by way of availability and quality. With the declining availability of fresh surface water sources, the agricultural industry has had to turn to groundwater and recycled industrial wastewater, in addition to recycling its own water for reuse. Bag filter systems help to remove sand, salt and any other solid particulate ranging from 1 to 1000 microns.
Surface-water Filtration - Surface water is that which is collected from streams, rivers, lakes, and reservoirs. Filter bag housings and bag filters remove dirt, salt, algae, and sediments that may have been collected.
