If there are signs of problems related to water quality issues, check the water immediately. Signs of problems are most often seen in boilers and cooling towers and may appear in any of the following forms.
- Higher energy costs.
- Frequent replacement of parts.
- Significant downtime.
- Scale buildup on the nozzles.
- High maintenance costs.
Regular sampling is recommended, even if there are no apparent problems. The source of water delivered influences the frequency of testing. In areas where the quality of the source water remains constant, modifications to the municipal water plant or distribution system may affect the quality of the water transported. In such cases, an annual inspection is recommended.
In areas where source water is affected by seasonal changes, it is essential to test the water each season to better understand and plan for differences. If the plant has its OK water supply, it is recommended that it be checked once a year to check for changes in the source water.
There are three sources of information about the water supply.
If the municipal council supplies the water, call them for an up-to-date analysis.
If the water supply is from an individual well, call your local water treatment specialist to check the water.
A third option is to contact a local inspection lab to analyze the source of water.
The scope of this analysis depends significantly on the use of the water in the facility. If water is used as a raw material for production, regulations or in-house engineering provide quality and testing requirements. If water is used as working water for cleaning/washing, cooling, or heat transfer, the following list of parameters should be analyzed. They provide a wide range of characteristics of make-up water and help determine the type of treatment required by the facility.
- TDS (total dissolved solids)
- TSS (Total Suspended Solids)
- Iron. Iron. The hyperbolic cosine value.
There is no "best" technology. Each technology is used to treat a specific type of water contaminant. Often, multiple technologies are needed to provide the best solution. Standard water treatment processes are.
- Filtration, used to reduce suspended solids, remove bacteria and iron, and absorb chlorine.
- Softening for removal of hardness and dissolved iron.
- Reverse osmosis for TDS, chloride, silica, and submicron suspended solids reduction
- Smaller, 5 GPM reverse osmosis units for boiler make-up water treatment
- Deionization for TDS, silica, and chloride reduction.
- Water treatment chemicals are used to adjust pH, alkalinity and eliminate bacteria.
- Ozone is used to eliminate bacteria.
- Ultraviolet light is used to destroy bacteria.
Water treatment depends on the application. Each use of water creates minimum requirements. The water supply does not meet the process specifications and must be treated. Even if the water quality meets the requirements, there may be opportunities for cost savings based on additional treatment.
By improving water quality, maintenance of various machines can be minimized. This cost reduction is very substantial and is the reason for the additional treatment.
The total cost depends on the quality of the source water and the degree of water quality improvement. Capital costs vary for various systems.
Capital cost per 100 GPM system.
Includes the following points.
- Chemical treatment.
- Ultraviolet light.
- Reverse osmosis.
Operating costs are also a factor. These costs typically increase with the level of contaminants in the feed water. The initial investment costs may seem high, but these costs offset the reduction in savings associated with higher quality water.
For example, heat transfer and boiler operating efficiencies can be increased by more than 20%. Reduced maintenance, downtime, and chemical savings also add to the base. Typically, water augmentation plans can pay for themselves in 1-2 years, even if the water quality is not low.
If all operations require treated water, a centralized system is recommended. There are many problems with centralized systems for high purity water. Depending on the type and length of the distribution path, there may be problems maintaining quality at the point of delivery. However, if there are multiple applications, each requiring a different treatment method, these systems should be reviewed and sized separately.
8. What is the life expectancy of water treatment equipment?
Most water treatment systems depreciate over seven years, but replacement life is between 15-25 years. After seven years, most major components need to be replaced, and rebuilding and new equipment must be studied. New equipment is recommended, but only if technological improvements can provide a more efficient operating solution to pay for the dismantling of old equipment, new equipment, and installation costs.
9. What are the essential considerations when selecting water treatment equipment?
When investigating the purchase or rebuild of an existing water treatment system, three factors in the selection of equipment, grid, product, and service. One of these factors are interrelated and determine the overall value offered.
Price is always the first consideration in a purchase decision, but all price components should be examined. This includes capital investment, operation, and maintenance costs, and installation. Product quality should influence every part of the price. When considering the cost of depreciation periods, products with enhanced features can often save money through reduced maintenance, lower operating costs, and increased reliability.
Also, inquire about the supplier's service factors. Since most water treatment systems are integrated into the overall plant operation, a quick service response, local spare parts, and treatment advice are invaluable assets for the water treatment system's smooth and long-term operation.
10. What are the latest innovations in water treatment?
The technology has not changed, but its application has evolved from strictly source water treatment to integrated recovery systems that can accept treated water for recycling in the process. For example, boiler examples condensate return circuits, zero blowdown cooling tower systems, and recovery of process water used for cleaning and purging. In these applications, water treatment can renew resources that have been abandoned in the past. Recycling reduces the dependence of many facilities on water resources and, most importantly, reduces costs and increases the bottom line.
