Abstract: Struvite crystallization is a methodology to remove phosphorus from wastewater and reuse as struvite (fertilizer) to ease both the scarcity of phosphorous rock resources and water eutrophication. Wastewater treatment plants, especially those employing secondary treatment and anaerobic sludge digestion, have historically encountered phosphate precipitates, most commonly being Struvite. In Established cities, the intensive livestock farming generates massive livestock wastewater with elevated concentration of phosphorous. Liberation of these compounds into surface water not only seeds to water eutrophication but also wastes phosphorus resources which is indispensable for the plant growth. Henceforth, it is crucial to remove the phosphorous from livestock wastewater with its recovery and reuse as fertilizer. As a valuable slow-release mineral fertilizer, struvite crystallization looks good on phosphorus recovery. The reaction factors including molar ratio of magnesium and phosphate, solution pH, co-existing substances and seeding assist of struvite crystallization are summarized. In this closure, struvite crystallization is a favourable tool to recover phosphorous from livestock wastewater. The blade agitator reactor which shall be setup and used is one of the promising solutions for removing more than 80% of phosphorous and recovering as struvite. Struvite precipitation occurs in an equimolecular concentration of Mg2+, NH4+, PO4 at slightly alkaline conditions. The raw wastewater type shall be the domestic wastewater & shall be collected from the Sewage Treatment Plant nearer to the locality. Initially Jar test shall be performed for 1L each to derive the optimum dosage of Mg source, A reactor shall be fabricated for up to 7.5litres of capacity. The fertilizers extracted from the wastewater using the Mg sources as reagents shall be used to grow the Ragi plants (Finger millet) and the observations shall be made at 7th, 12th, and 18th day. Five pots shall be used, where 1st is for conventional (absence of fertilizer), chemical fertilizer (urea) shall be used in 2nd, fertilizer such as MgCO3, MgCl2 and MgSO4 shall be used in 3rd, 4th, and 5th pots respectively. A Comparison is to be made for the use of MgCO3 (struvite fertilizer) & MgCl2 and MgSO4 and similar results compared to chemical fertilizer (urea) used in the plant growth, thus using struvite crystals as fertilizers shows the faster growth rate. After the struvite crystallization process in the supernatant, Phosphate and Nitrate removal from the wastewater sample is also planned to be assessed.
