The application of SBR in the treatment and nutrient recovery of sludge from the ISF can be a potential technical alternative to current technologies in the management of sludge. The objective of this study was to evaluate the removal efficiencies and recovery performance of nitrogen, carbon, and phosphorus (P) in sludge from the intensive whiteleg shrimp ponds under different sequences of react periods (aerobic/ anoxic).

In general, the phosphorus use efficiency is less as only 30 % of the applied phosphorus is taken by plants in its entire growing season and phosphorus recovery efficiency of applied fertilizers in soil by the crop plant is less than 20 % (Fageria et al., 2011). Intercropping system is one of the best strategies to improve PUE (Hasan et al., 2016).

In this study, salmon by-products were utilised to produce high ash content (AC) salmon bone powder (SBP) using hydrolytic enzyme and apply in the production of Tra catfish cake. The byproducts included 61.9 of moisture, 43.1 of protein, 45.4 of lipid, 10.2% of ash, 3.7 of calcium and 2.3% of phosphorus (on dry weight basis).

Linseed is one of the most important crops and it has exceptionally high content of AlphaLinolenic acid, dietary fiber, high quality protein, phytoestrogens and minerals especially phosphorus, magnesium and calcium. To increase the uptake of linseed, value addition is attempted. Standardization of protocol was carried out based on pH, titrable acidity and sensory characteristics for the parameters - seed processing technique, substrate, sugar, inoculum, honey concentrations, incubation temperature and fermentation duration using Lactobacillus acidophilus and Saccharomyces ellipsoideus.

Phosphogypsum is a by-product of the wet phosphoric acid production. In this study, chemical compositions of phosphogypsum waste (PG) in Hai Phong diammonium phosphate plant (DAP1) and Lao Cai diammonium phosphate plant (DAP2) in Viet Nam were surveyed for the purpose of gypsum recovery by P2O5 , F removal to meet TCVN11833 for use treated gypsum as cement retarder. Studies of impurities P2O5, F, TOC removal by sulfuric acid 10 % at 28 oC was presented.

In coastal areas and islands, farmlands often lack of nutrients. This research assessed the precipitation of phosphorus presenting in urine in the form of struvite of magnesium ammonium phosphate (MAP) by adding of supplement of Mg2+ ion from MgCl2 solution contained in seawater (Cat Ba island area). The urine and seawater have been mixed at different ratios.
