How do you dissolve struvite in pipes?
RYDLYME is extremely effective in struvite removal from the piping and other affected equipment in wastewater treatment plants. The amount of RYDLYME required will be dependent on the severity of the struvite accumulation and the volume of the system to be cleaned.
How is struvite formed?
Struvite stones form when urease production by urinary bacteria results in the formation of ammonium ions as well as alkaline urine. In this setting, phosphate is present in its trivalent form and combines with three cations, ammonium, magnesium, and calcium, the last as a component of carbonate apatite.
What is struvite in wastewater treatment?
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.
How do you prevent struvite formation?
Struvite Prevention Solution The most cost-effective method is to control (chelate) the magnesium and keep it in solution. MAP will not precipitate. If one has MAP crystals already formed, then by chelating the magnesium from the MAP crystal, you can solubilize the ammonia and phosphate back into solution.
Will vinegar dissolve struvite?
Some people advocate for the use of apple cider vinegar (ACV) in cases of struvite crystals, as they are said to help dissolve the crystals. Bladder blockage is a life-threatening emergency, so always discuss any treatment options with your veterinarian.
What are the chemical constituents of struvite?
Struvite Composition and Struvite Formation from Wastewater Phosphorus comes into the plant as phosphate from our dishwasher and laundry detergents. The struvite chemical formula is written is NH4MgPO4•6H2O. The anaerobic digester in combination with the pipes and pumps makes a terrific growth site for Struvite.
Is struvite soluble in water?
Struvite has low solubility in water, with a solubility constant of 10−13.26 (Ohlinger et al., 1998). In contrast, it is readily soluble in acidic environments: 0.033 g 100−1 mL−1 in 0.001 M HCl and 0.178 g 100−1 mL−1 in 0.01 M HCl at 25°C (Le Corre et al., 2009).
What pH does struvite form in?
pH values above 8.5 are known to be optimal for chemical struvite precipitation4,33,34, hence, it was expected that solid precipitate formation was high in the controls due to the formation of precipitates through chemical routes.
What causes struvite wastewater?
When magnesium, ammonia, and phosphate come together in the plant’s piping system, it precipitates and causes struvite crystals to form. If left untreated, these crystals turn into rock like formations and heavily restrict flow through pipes and clogs equipment.
What is the chemical formula for struvite?
Struvite, also known as magnesium ammonium phosphate, has the chemical formula MgNH4PO4·6H2O. Conditions that affect struvite precipitation include pH, molar ratio of Mg:NH4+:PO43–, competing ions such as calcium, temperature, and mixing intensity and duration. For instance, optimum pH conditions are pH 8.5 or higher.
What is the melting point of struvite?

Is coffee bad for kidney stones?
Caffeine intake has been shown to be associated with increased urinary calcium excretion (6) and, as such, could potentially increase the risk of developing kidney stones, although in our previous reports we consistently found an inverse association between consumption of caffeine-containing beverages, such as coffee …
How does struvite affect a water treatment system?
Struvite, also referred to as MAP by the wastewater industry, is a phosphate mineral that forms on the interior of pipes, pumps, anaerobic digesters, and other water treatment equipment. The formation of struvite scale and rock crystals slows the flow of fluid and over time, can clog and damage your wastewater systems.
What kind of mineral is struvite in water?
What is Struvite? Struvite, also referred to as MAP by the wastewater industry, is a phosphate mineral that forms on the interior of pipes, pumps, anaerobic digesters, and other water treatment equipment.

What can I use to remove struvite from pipes?
Struvite Remover STSR: Our buffered, non-corrosive and non-hazardous struvite scale remover dissolves scale and rock without damaging pipe metal or pump components. Vivianite Remover: Struvite Wastewater Remover STSR is effective at eliminating hard to remove vivianite crystal formations from pipes.
How can you tell if Crystal Rock is struvite?
Rough surface areas are one of the first areas to look for struvite formation. When struvite crystal rock is not 100% removed from the different surfaces, the remaining rough edges will form struvite more quickly. What Are the Tell-Tale Signs of Struvite Formation?
