Struvite Removal is sponsored by Jayne Products. Jayne Products is a manufacturer, formulator, and distributor of Green Chemical Cleaning products for an array of industries including Oil Refineries, Wastewater Plants, Manufacturing, Machinery, Transportation, etc. We have been in the Oil and Gas industry for over 30 years and branched off into other industries. We developed new products including our Struvite Removal, Stuvite Prevention and Descaler products in the more recent years that have a great success rate internationally. We are located in Carson, California, United States, conveniently located by the Los Angeles Ports for shipping and distribution. Over the course of our Struvite Wastewater Treatment involvement, we have conducted many tests, procedures, case studies and processes and will develop a custom plan for your struvite or scale needs.
Struvite Removal is sponsored by Jayne Products, which manufacture and distribute water treatment chemicals. Please contact us today and we will happily provide you with free samples of our products so that you may test them yourself on your Struvite or Vivianite samples, to test their effectiveness as scale removers and preventers. We differ from our competitors because we have developed test procedures, which ensures 100% effective removal. Struvite Removal also has a software program, which can calculate potential Struvite and Vivianite extent so that we can estimate the amount of product you will need to solve your problem.
When looking at photographs of struvite filled piping and clogged valves, it always leads to the question, “How do you remove struvite from waste water treatment plants (WWTP) or Concentrated Animal Feeding Operations (CAFO) without causing a major interruption?” We interviewed Charles Jennings; he is a consulting engineer for WWTPs and CAFOs, who has spent a great deal of time on the best ways to remove struvite. He gave us a few tips and shared a few of his experiences with struvite.
One of the easiest ways to stay on top of a struvite or vivianite problem is to utilize the plant data that you are collecting 24 hours a day, seven days a week and take full advantage of it. One of the pieces of data that you will have in your logs is the time it takes for a batch of solids to process through the plant and in some cases you have the data that tells you how long it takes to move from the anaerobic digester to your sludge tanks.
Jennings related to us that there was one WWTP that had a fourteen inch (14”) diameter transfer line that moved sludge from the anaerobic digester to the sludge holding pond. They noticed that it was taking 45 minutes to transfer when it should only take 4 minutes to pump the sump. When it got to the point that it was interfering with their process, they ended up replacing the valve – and it was then that they discovered that struvite had completely blocked the valve. This particular plant had periodically maintained the valve by mechanically cleaning by hydro-jetting, but that only cleaned the easy to dislodge struvite. If they had wanted to really clean the valve mechanically, they would have had to use a grinder, and that would have meant not having the valve available for a week or more.
An alternative method for removing struvite that is much easier to administer and control than mechanical grinding and spraying. JS 9325 is a liquid solution, environmentally safe product that has proven itself over time to remove struvite efficiently and cost-effectively. JS 9325 is very effective at safely attacking and dissolving the struvite crystal (rock) by targeting the magnesium component of struvite. Struvite is a compound made up of three elements: magnesium, ammonia and phosphate. In WWTPs when these three elements specific weight ratio (1:1:1) is met, struvite precipitates out of the plant’s liquid. WWTPs attempt to control struvite precipitation by controlling the pH and magnesium level of the liquid, as well as the CO2 release from the anaerobic digester. JS 9325 attacks the magnesium in the existing struvite crystal, causes it to go back into solution and the struvite breaks down. The rate at which it takes to dissolve the struvite is a function of time and concentration.
One of the more recent questions of Wastewater Treatment is 'What is Struvite?'
The scientific community defines struvite as a phosphate mineral crystal whose elemental composition of magnesium, ammonia and phosphate forms in water and is chemically written as NH4MgPO4•6H2O.
Struvite is also referred to as MAP by the wastewater industry, which stands for the nutrients magnesium, ammonia, phosphate compound, it forms when there is a mole to mole to mole ratio (1:1:1). The ammonia is from the urea in wastewater, phosphate is found through food, soaps and detergents.
Struvite can also be known as a form of scale or rock crystal formations and will be found in varying colors from white to yellow to brown, depending upon the MAP content in the water. Note that because struvite is not produced by strict stoichiometry calculations, i.e., struvite develops differently depending on water conditions and local process applications at their treatment plants. Various types of struvite need different treatment regimes for struvite control and struvite removal.
Struvite is a problem in sewage and wastewater treatment. Struvite is a form of scale that forms in pipelines, belts, centrifuges, pumps, clog system pipes, digester, Recreational Vehicles (RVs), CAFO (confined animal feeding operations), buildings, etc.
