摘要： A method of treating an algal containing aqueous medium comprises adding an effective amount of the treatment composition to the aqueous medium wherein the treatment composition comprises 1) a) a water soluble cationic quaternary ammonium starch or b) a water soluble quaternary ammonium starch/gum blend or c) a water soluble modified tannin and 2) a metal containing inorganic coagulant. In certain aspects of the invention, the so-treated algal containing aqueous medium is filtered such as by microfiltration and/or ultrafiltration to result in potable water. In another aspect of the invention, the algal containing aqueous medium is an agglomerated mass of algae with water dispersed throughout the mass. The method comprises a step of separating the algae from the water, thereby harvesting the algae for further processing such as may ultimately lead to the production of biodiesel fuel.

摘要： Recalcitrant chemical oxygen demand (COD) of a liquid is reduced in a water treatment system. The method includes pretreating the liquid in a pretreatment unit to remove indigenous bacteria or microbes to a population level below which the indigenous organisms can interfere with the screened and externally introduced microorganisms. The liquid is then provided to a reactor that has a filter bed formed with a carrier material. Special microbes are screened and used to colonize the carrier material to remove recalcitrant COD. A biofilm is cultured on the surface of the carrier material to immobilize the screened microbes in the reactor. The method further includes percolating the liquid from the pretreatment unit through the filter bed colonized with the screened microbes to degrade at least part of the recalcitrant COD under aerobic conditions. In one embodiment, the filter is formed with biological granular activated carbon (GAC) as the carrier material and the screened microbes comprise at least one microbial species selected from the group consisting of Bacillus, Comamonas, Arthrobacter, Micrococcus, Pseudomonas, Pediococcus, Achromobacter, Flavobacterium, Mycobacterium, Rhodanobacter, Stenotrophomonas and Yeast.

摘要： A membrane filtration process includes pretreating an influent solution to remove suspended solids, to produce a pretreated solution. pH of the pretreated solution is adjusted to at least 8.3 or lower by injecting CO2 into the pretreated solution, to produce a conditioned solution. Injecting CO2 also serves to supplement bicarbonate in the conditioned solution. The conditioned solution is flowed through a membrane filtration unit, to produce a permeate solution and a retentate solution. The membrane filtration unit comprises reverse osmosis membranes or nanofiltration membranes, or both. The retentate solution is then treated to cause precipitation, to produce a supernatant solution and a reject solution. At least a portion of the supernatant solution is recirculated by combining it with the influent solution prior to the step of pretreating.
