Reduce Potential Downtime with Wastewater Treatment Product Storage and Management Best Practices
Using coagulants and flocculants to remove suspended solids during industrial wastewater or influent surface water source treatment is common practice. However, failure to properly store or manage these chemicals can lead to downtime, impact on production, accrued costs, decreased equipment reliability and shortened lifespan, on-site safety issues, and more.?
For instance, poor water quality entering a process for boilers, cooling towers, or process makeup can severely impact the reliability of the equipment, potentially leading to downtime or reduced output, impacting a facility’s bottom line. Similarly, if wastewater is improperly treated due to chemical feed, storage, or supply issues, a facility risks violating wastewater discharge permit parameters, resulting in monetary fines and poor public relations.
Improperly stored and managed products used for water treatment can also lead to on-site safety issues for personnel dealing with handling and the disposal of these should a product’s integrity be compromised and require replacement.
As such, it’s important to ensure best practices on chemical storage and management are followed when putting together and executing a treatment program.
Storage basics for coagulants and flocculants
Understanding the characteristics of treatment chemicals is crucial to employing proper storage while building a successful treatment program.?
Coagulants vary in chemistry type, each with different characteristics, such as viscosities, pour point, and freeze point temperatures. Available storage containers, as well as feed and conveyance equipment, are important aspects of setting up a program. For example, while many coagulants have a relatively low viscosity and are easy to pump with standard chemical metering pumps, some higher-viscosity coagulants require specialized pumps to ensure proper dosing occurs.
Similarly, flocculants come in several forms (emulsion, powder, solution, etc.), each of which requires unique storage, handling, and feeding needs to ensure optimal performance. For instance, powder flocculants should be stored in conditions that avoid moisture contamination.
The characteristics and capabilities of each product are also important when changing or reusing storage containers and tanks. Care must be taken to confirm if the new and old products are compatible, or if full removal of the existing product residual and container rinsing is needed. Container clean out may be required and supplier guidelines should be followed. Coagulants and flocculants often cannot be mixed, even with similar chemistries.?
Product Safety Data Sheets (SDS) often have key information on chemical characteristics. Still, the end-user needs to work with the product supplier to ensure these factors are reviewed before implementing any program.?
The end user’s Environmental Health and Safety (EHS) policies on where and how to store coagulants and flocculants, government regulations, and the purchaser and/or end-user’s company guidelines are critical to follow to ensure proper storage, use, and safety.
Identify product use rates and inventory management
Another important consideration involves how much product to order at any given time to keep in inventory. For liquids stored in larger tanks, tank level sensors may be used to collect data on real-time product use and monitor inventory. This can be vital in inventory management and purchase decisions. Full-service suppliers commonly work closely with customers to ensure the right amount of product is ordered.
Ensuring inventory levels are large enough that the product does not run out decreases the risk of requiring temporary water flow reduction through the system to meet discharge limits, short-term curtailment of water treatment, or worst-case scenario, reduced or loss of manufacturing production at the site. Products should be ordered to have enough on hand in case inlet water conditions change, which may drive up use rates.?
In summary, coagulants and flocculants are commonly used to treat surface water and wastewater in various industries. Understanding how each product used should be stored, handled, and applied is important to ensure the best treatment outcome.
