Different filter types have different applications. Utilizing filters in the correct way can greatly increase the optimization of water systems.

🌧🚰 ASR (aquifer storage & recovery) has been an ongoing experiment throughout many locations in Florida to address the conservation of potable water sources.

The demand for water due to development and farming is straining many of the aquifers; this causes drops in water levels to the point where saltwater intrusion is becoming a major issue.

To mitigate aquifer water loss, state government agencies have been providing grants for ASR pilot programs. These programs take advantage of Florida’s average annual rainfall of +/- 40 inches per year by pumping surface water underground through drilled wells for later withdrawal.

Many Florida aquifers are porous limestone formations, where freshwater flows through the pores. Before pumping underground, the water must be filtered to meet the limestone porosity protection guidelines. Geologists and engineers determine the final filtration degree necessary to protect aquifer porosity. The challenge is trying to establish the correct stages of filtration for surface water. Each stage of filtration removes a segment of the particle sizes in the water until the final stage of 25 microns is reached.

Once in the aquifer, the water is withdrawn and tested for all constituents that would have an effect on the final potable drinking water treatment.

While filtration in these programs has been successful, other problems involving water chemistry, such as arsenic levels, have proven to be a challenge.

Orival was contacted for just such a program in North Port, Florida. Pictured below are 6 filters for 2 stages of filtration (x2 80 micron units followed by x4 25 micron units) from that installation.

Thanks to all those who stopped by our booth at NPE 2024!

We loved learning about the different processes surrounding the plastics industry and look forward to discussing them further to see how we can help!

Another successful startup with our northern neighbors in Ontario ⚙️🔧

A commercial building’s aging chiller and cooling tower were recently replaced and an Orival filter was added. A filter configuration was chosen that could fit into the existing mechanical room. Thanks to our sales partners, GPA Inc. and building staff for providing the sales and engineering support for this job.

Pictured below is the new chiller and filter that were installed. A 3” side-stream line can be seen coming off of the 8” main chilled water line prior to entering the chiller. A booster pump was used to raise the pressure in the side-stream line from 20 to 40 psi. This provided the necessary pressure for the filter’s automatic rinse cycle and allowed the side-stream to be pumped back into the 20 psi, 8” main line.

A new Florida citrus grove 🍊 with an existing low operating 25 PSI pump station required a unique solution.

Automatic filters need a minimum operating pressure of 30-35 PSI during cleaning to effectively remove debris from the elements.

Unfortunately, this application could only provide 22 PSI at several double-filter sites in the field.

The Orival onsite sales engineer reviewed the operating parameters and modified a few mechanical peripherals to successfully operate all five filter installations.

At each site the flow rate was 1800 GPM with 200-micron screens, and because of the remote locations had to be equipped with battery-operated controllers.

A smooth start-up in a downtown Toronto mall! 🎉

Thanks to our sales partner, GPA Inc., and all those involved, for a successful startup of a 4” self-cleaning filter in this tight squeeze 🤏 of a mechanical room.

The filter is protecting the plate-and-frame heat exchanger pictured.

With the rising need for data centers throughout the world, comes the rising need to cool data centers ❄️, and cooling data centers many times requires water💧.

Whether this water is recirculated and passes through a cooling tower or is taken from another body of water such as a lake or river, it requires filtering. Filtering cooling water ensures clean heat transfer surfaces and prevents clogging in your cooling system from things like algae, leaves, pollen and other particles found in the water or air.

The following 3 skid mounted systems are used for side-stream filtration of 3 BAC cooling towers’ heat rejection loop. They each filter about 10% of the cooling tower’s 2700 GPM flow.

The filters were originally supplied with 10 micron sintered screens which were later changed to 100 micron sintered screens as it was found that they could still supply the desired amount of particle removal while reducing the rinse frequency.

Reducing energy use and conserving potable water.
When we all do our part, we all benefit ♻️💧

A resort in the Bahamas makes use of non-potable sea water 🌊 in the heat rejection loop of their AC system’s chillers. This allows them to conserve precious potable water and reduce energy usage.

To maintain optimal heat transfer efficiency, a self-cleaning filter with a 500 micron screen was chosen for removing suspended particles from the sea water.

To withstand the corrosive salt water, the filter is made of 316 stainless steel and protectively coated with a 2-ply sea water coating.

The unit pictured is one of seven such filters installed in the resort.

A point-of-entry (POE) city water filtration system to prevent scale, rust and other suspended solids from contaminating sensitive lab equipment and sanitizers in a U-Penn building.

City underground mainlines, some from the 1800s, contain layers of debris from settling in low water velocity segments from the distribution system.

When there are line breaks, construction repairs, or city fires this sediment can break loose and cause plugging and contamination of sensitive building equipment.

Having a POE filter can mitigate these issues and provide less maintenance of other building mechanical support schemes.
