CALCIUM INJECTION PROGRAM FOR IMPROVING THE QUALITY OF EFFLUENT WATER
Water chemistry problems common to effluent water can impose limitations on the use of wastewater for irrigating golf courses, sports fields and other
green areas because soil always takes on the characteristics of the water it is irrigated with. Amending the effluent with gypsum can optimize water
quality, minimizing or eliminating its negative impacts on turf, plants and soil. Simply put, better water creates better soil conditions, which
ultimately improves overall growing conditions.
|Golf courses are typically the largest user of reclaimed water, and yet they are also the most sensitive to water quality issues. The health
and appearance of golf courses dramatically impact both their real and perceived value, as well as the quality of play and the overall golf experience. The most serious
problems associated with irrigation water are sodium and bicarbonate content. Virtually every course already has an amendment program in place to deal with these elements.
However, because soluble gypsum is logistically difficult to handle at the course level, water and soil amendment is generally accomplished with the use of sulfuric acid
or sulfur burners.
|Sulfuric acid is extremely dangerous to handle and, besides deteriorating any metal components it comes in contact with, it also exposes the
municipality and/or golf course to a serious potential health liability. Sulfur burners are safer, but they are unsightly on the golf course and produce an
annoying sulfur smell. By amending the effluent at a point nearest the source, all downstream users enjoy the benefit of improved water, and each one will
also then enjoy the cost savings associated with a reduced acid treatment
program. When considered together, these actual and potential savings will often minimize, or
even completely offset, the cost of implementing a single calcium injection site upstream.
|The bigger benefit for the City is that improving wastewater quality encourages its reuse for turf, landscape and agricultural applications in general,
and also increases its resale value. At the same time, it serves to help the environment by reducing the amount of acid being used by treating the effluent with
all-natural organic gypsum. Our gypsum injection program is made even more attractive by the ability of Wastewater Solutions to provide all of the equipment and
operate the system at their own expense, billing the City only for the gypsum as it is used, together with a monthly service fee. No capital purchase is required!
The Aqua-Ject® system is equally suited to new construction, or as an easy retrofit to existing treatment plants.
The Municipality then may choose to pass on this cost in the form of a higher selling price for the effluent water, or absorb the cost as a way to further
encourage its use. At the end of the initial Supply Agreement, the municipality may choose to either terminate the program and have the equipment removed,
purchase the installed Aqua-Ject® equipment and own it, or simply continue the program as a Service and Supply agreement for as desired. This is truly a
win-win-win situation for the Municipality, the golf courses and the environment.
Wastewater Solutions personnel can put on a slide presentation for the local golf course superintendents, together with the City personnel involved with managing
the wastewater treatment plant. We would be happy to sponsor a luncheon at a local restaurant or golf course as a convenient and casual forum to present the
program and discuss its viability for implementation in your area.
