“…In addition, the post-reaction disposal of such industrial inhibitors leads to pollution of the environment. [17][18][19] For example, when such P and N containing compounds reach water ways, they play a key role in eutrophication which can cause major ecological damage. 19 Therefore, the concept of "Green Chemistry" was proposed and scale inhibitors that are not detrimental to our environment have become a recent focus for inhibiting industrial scale formation.…”

“…Indeed, food security is 47 increasingly dependent on the availability of phosphate fertilisers. As natural phosphorus reserves 48 continue to deplete, it is necessary to improve resource efficiency by investing in the recycling 49 and recovery of phosphorus [1]. A considerable proportion of the phosphorus consumed by 50 society ends up in municipal wastewater.…”

. Phosphorus recovery from digested sludge centrate using seawater-driven forward osmosis. Separation and Purification Technology, 163 1-7.Phosphorus recovery from digested sludge centrate using seawater-driven forward osmosis AbstractIn this study, we demonstrate a novel seawater-driven forward osmosis (FO) process to recover calcium phosphate precipitates from digested sludge centrate without any chemical addition and draw solute regeneration. The FO process effectively pre-concentrated phosphate and calcium in the digested sludge centrate. Spontaneous precipitation of calcium phosphate minerals in the digested sludge centrate was achieved by the sustained concentrative action of the FO process and the gradual pH increase due to the diffusion of protons to the draw solution. Pre-concentrating digested sludge centrate by three-fold resulted in a 92% recovery of phosphate via precipitation. The phosphate precipitate only constituted 3% of the total inorganic solids recovered, therefore subsequent treatment steps would be required to recover phosphorus in a useable form. A water flux decline of 30% from the initial value was observed as the digested sludge was concentrated by three-fold. This observed water flux decline was mostly attributed to the decrease in the effective osmotic driving force due to the increasingly concentrated feed solution and diluted draw solution. It is also noteworthy that membrane fouling was readily reversible. By flushing the membrane with deionised water and subjecting the membrane to feed and draw solutions with the same osmotic pressure as the initial conditions, complete water flux recovery could be achieved. of the total inorganic solids recovered, therefore subsequent treatment steps would be required to 32 recover phosphorus in a useable form.
