The present invention relates to natural crude salt formulations arid their cost-effective preparation. In particular, the invention discloses the fractionation of seawater into three fractions which can thereafter be suitably combined to reconstitute seawater in its pristine form for its various applications such as growth of marine microbes, flora and fauna in a marine environment, especially where such environments have to be created in locations far removed from the sea and/or where there is a requirement to modify the composition of seawater to better its performance. The fractions can also be blended appropriately to exclude the major constituent, namely sodium chloride, and thereby be useful for mineralization/re-mineralization of waters which are deficient in mineral nutrients such as calcium, magnesium, potassium, sulphate and bicarbonate including rain water and desalinated waters obtained through thermal/RO desalination. The invention can be practiced most cost-effectively in solar salt works operated on sea brine.

Process for the preparation of natural salt formulations for seawater substitution, mineral fortification

An energy efficient process for the preparation of marine microalgaefatty acid methyl ester (CME) from hydrolysate of deoiled cake of(JOCH) and crude glycerol co-product stream (GL7 and GL8) along with seawater diluted with tap water (1:2). A small part of the crude glycerol layer in case of JME is processed to recover glycerol for glycerol washing and the otherwise problematic still bottom is utilized for microbial synthesis of PHAs and the rest is utilized for Microalgal conversion of JME byproducts into CME. The remaining part of the methanol-depleted glycerol layer is utilized, along with hydrolysate of thedeoiled cake (JOCH), for single-stage Microalgal production of lipids by a marine Microalgal isolate (sp.) without the need for any other nutrients. Waste streams from the microalgal processes can be discharged directly into agricultural fields as biofertilizer or recycled back in the mass cultivation.
