FRACTIONED SEPARATION OF VALUABLE SUBSTANCES FROM AQUEOUS MANY-COMPONENT MIXTURES
20200247701 · 2020-08-06 ·

The invention relates to a method for the fractioned separation of valuable substances from aqueous many-component mixtures such as aqueous wastes, sludges and sewage sludge under supercritical conditions. The invention also comprises valuable substance fractions that are enriched after the method according to the invention, more particularly phosphorous-containing and phosphorous- and ammonium-containing compounds such as fertilisers and synthesis gas as an energy source and as a valuable substance for the chemicals industry. The invention comprises devices for carrying out the methods. With the method and devices according to the invention, valuable substances can be completely recovered from wastes, sludges and sewage sludge and given a new use. The methods and devices are particularly suitable for recovering phosphorous and ammonium in the form of plant-available fertiliser, for recovering metals and heavy metals, for producing synthesis gas and for obtaining hydrogen from synthesis gas, i.e. for mobility.

Special film-coated release calcium fertilizer for peanut and preparation process thereof

A special film-coated controlled release calcium fertilizer for peanut includes a three-layer structure. Raw materials in an inner layer include calcium nitrate, humic acid, seaweed extract and adhesive. Raw materials in an intermediate layer include calcium nitrate, urea formaldehyde powder and chitosan oligosaccharide. Raw materials in an outer layer include urea formaldehyde powder and fermented livestock and poultry manure. The special controlled release calcium fertilizer for peanut releases Ca since the pod-bearing stage after the basal application. The coating film is a biodegradable film, releases calcium since about 50 days after application into soil.

INTEGRATED WASTE CONVERSION SYSTEM AND METHOD

An entirely water-based, energy self-sufficient, integrated in-line waste management system is provided for comprehensive conversion of all organic fractions of municipal and wider community waste to fuels suitable for use in transportation, with all solid residues converted to high nutrition compost. The system is based on a combination of pre-treatment, involving alkaline hydrolysis and saponification; three-way separation of the pre-treated waste into different streams that are each directed to suitable further processing including fuel production; which includes biodiesel generation in a continuous-flow catalytic esterification unit, and anaerobic digestion to produce methane or other small molecule biofuel. Remaining solids are converted to compost in a quasi-continuous process.

Methods and Systems for Stabilizing Organic Material

The present application relates to systems and methods for processing organic material. The methods may include extraction of biochemical nutrients from organic material, such as food scraps. The method can include comminuting the organic material to form a slurry from components comprising liquid and organic material; combining the slurry with microorganisms, such as a yeast, under aerobic conditions to form a mixture of the slurry and yeast; aerating the mixture; and forming a biomass and a nutrient-rich broth, in which the biochemical nutrients are stabilized and anabolized. The systems may, in some embodiments, be configured to perform the methods of processing organic materials.

Process for potash recovery from biomethanated spent wash with concomitant environmental remediation of effluent

Molasses based alcohol distilleries generate highly contaminated, dark coloured and foul smelling effluent (bio-methanated spent wash, BMSW, also known as post methanated effluent). While the prevailing practices for treatment of alcohol distillery effluents operate on the premises of liability management, high potassium content of spent wash (ca. 2% w/v in BMSW) offers an opportunity for its utilisation in production of potash fertilizersa major agricultural input. The present invention provides process for potash recovery from BMSW with concomitant environmental remediation of effluent. The process involves pre-treatment of BMSW followed by potash recovery through selective precipitation technique to produce potash fertilizers and activated carbon while generating a relatively benign effluent (>80% remediation). It may further be possible for the alcohol distilleries to achieve ZLD status by incorporating commercially practiced water recovery techniques (viz., multiple effect evaporation/nano-filtration/reverse osmosis etc.) for downstream processing of the process effluent.
