In order to fully service our clients and end users, Pro Aqua also offers a variety of services to help maximize the efficiency of our customer’s treatment equipment and systems. These services include clarifier services, diffuser/ aeration services, rotary lobe pump services, filter cleaning, odour characterizations/ studies, and equipment conditions assessments.
For clarifier service, Pro Aqua not only represents Evoqua for capital sales, but we also provide service for their clarifiers all over Canada. This includes training, inspections, drive repairs/ replacements, as well as equipment assessments. If your current equipment is not made by Evoqua/ Envirex, we also provide adaptors and custom equipment to fit most applications.
Pro Aqua is the full-service sales representative for Sanitaire (Xylem) in Ontario providing a series of diffuser/ aeration services. We provide training, start-up/ commissioning, and site inspections for capital and aftermarket installations for Sanitaire systems. These are our standard services for aeration equipment. In addition to this, Pro Aqua provides diffuser replacement service, ceramic diffuser gas cleaning (see below for more detail) and aeration system assessments.
For pump service, Pro Aqua provides any needed service on Boerger Pumps and Grinders. This includes standard services such as training, inspections, and start-up/ commissioning that is generally a part of any pump purchase (as specified in each project). In addition to this, we can provide lobe replacement, mechanical seal replacement, oil changes, and equipment assessment services.
Pro Aqua also represents a unique chemical manufacturer, called Blue Earth Products, who provides a full line of specialized cleaning products. In addition to providing the chemicals, Pro Aqua can also provide filter cleaning including in situ media, underdrain and backwash system cleaning. This can restore the performance of a filter to like new condition. As a part of this service, if you provide samples of your media, Blue Earth Products will test the media for sample cleaning efficiencies and elemental breakdowns of the residues that are building up on the media. This can not only tell you the condition of your media, but also give you some idea of where your foulants are coming from providing helpful process information to operators.
Pro Aqua also represents some state-of-the-art odour control equipment. In order to ensure that your current odour control system is working correctly, we can perform an odour characterization and assessment of your current system. This includes independent laboratory sampling and specialized odour control engineer review. In addition, we can provide odour source characterizations as well as dispersion modelling which not only helps with existing equipment, but can also help ensure that the correct equipment is being installed for new applications.
With over 30 years of water and wastewater equipment and a linecard that includes a full flow sheet, Pro Aqua has a well-rounded and thorough understanding of water and wastewater treatment. Our staff can provide process equipment assessments (for nearly any treatment equipment) giving feedback on lifecycle, any needed repairs/ maintenance, as well as overall process performance of your treatment plant.
Please call us if you have any questions or concerns regarding service, as we are willing and able to provide additional services if needed. Please feel free to contact us also for overall support as we hope to provide innovative ideas on how to keep your treatment plant running smoothly and efficiently.
For aftermarket services, please contact Tracy Lenhardt at firstname.lastname@example.org or by phone at 905-864-9311 ext. 224.
Sanitaire is a name has the been synonymous with fine bubble and coarse aeration for years in the municipal water and wastewater markets. If you have installed any of their systems in your plant, then you have the O&M Manual explaining the what’s, how’s and when’s of routine maintenance; but how many plants are really keeping up with it? What difference does it make to the operation of your system from a process standpoint? What about from an efficiency standpoint? The following will explain why you should keep your ceramic diffusers clean and how we propose that you do it.
Biological secondary treatment is the single largest energy cost for a municipal activated sludge wastewater treatment plant, accounting for up to 60% of the total energy consumption of a plant. As a result, there is a great opportunity to save energy and money by ensuring that the system is running as efficiently as possible. The gradual fouling of diffusers happens over time and increases with each shutdown/ start-up that the aeration blowers experience. A fouled diffuser not only causes backpressure on the air header, but also results in inefficient transfer of oxygen. The photo below shows the impact that the fouling has on the bubble size and uniformity.
As you can see from the photograph, there is a notable difference in the quantity and size of the bubbles which greatly affects the oxygen transfer efficiency of your system as well as its energy usage. Regular cleaning and maintenance of your system will ensure that your system is working optimally with consistent performance and doing so with a substantial reduction in energy costs. There are five general warning signs that it’s time for you to clean your diffusers:
- More air is required to maintain process performance
- Residual DO levels are decreasing or are too low
- The back pressure at the blowers in increasing
- There is an increase in energy consumption of the blowers
- It has been over a year since your last cleaning
The in-place gas cleaning that Pro Aqua offers has some very unique benefits that can greatly improve the performance of your aeration system and also minimize any impact to the process of the plant. The key benefits of the patented In-Place Gas Cleaning are as follows:
- The cleaning can be done while the plant is in service without interruption or reduction in capacity. It is an in situ process that uses the air from normal blower operation to push the anhydrous HCl gas through the ceramic diffusers. There is no need to dewater the aeration tanks and remove them from service to return them to like-new.
- It eliminates the need for any labour-intensive manual cleaning in confined spaces and the need to remove tanks from service.
- The cleaning of the porous ceramic discs removes biologically-fouling and scaling.
- The result of the In-Place Gas Cleaning will reduce the diffuser Dynamic Wet Pressure (DWP) to like-new condition and restores the Oxygen Transfer Efficiency (OTE) to the same.
- It reduces blower back pressure, discharge volume, and electrical energy costs.
- Diffuser cleaning not only has direct impacts on the process and performance of the diffusers, but also extends the life of blowers. Not only will there be a reduction in header pressure, but the amount of air required to maintain BOD goes down. As you can see in the photo above, the bubbles become much finer increasing contact surface area and maximizing the efficiency of the oxygen transfer.
- This system is proven. There have been hundreds of installations to date that have returned the operation of the aeration systems to like-new condition.
The bottom -line benefits are significant power savings, improvement of process performance, elimination of plant downtime and reduced maintenance costs and it should be done routinely at least once per year depending on your plant’s loading.
