Abstract: A method for treating water including: passing water to be treated containing organic matters and ammonia nitrogen through a reaction tank containing a carrier for treatment under aerobic conditions, wherein a water content of the carrier is 50% or more and 96% or less; the carrier has continuous pores with a pore size of 30 ?m or less; an organic matter concentration in the water to be treated is 100 mg/L or less as a BOD5, and an ammonia nitrogen concentration is 50 mg/L or less; a retention time of the water to be treated in the reaction tank is 2 hours or less; and the organic matters and the ammonia nitrogen in the water to be treated are treated in the same tank.

Abstract: A process for treating wastewater including: feeding organic wastewater to a first aerobic tank and an anoxic tank; nitrifying and denitrifying the organic wastewater by bacteria supported on carriers in the first aerobic tank followed by discharging primary treated water; denitrifying the organic wastewater and the primary treated water by bacteria in an activated sludge in the anoxic tank followed by discharging secondary treated water; nitrifying the secondary treated water by bacteria in an activated sludge in the second aerobic tank followed by discharging tertiary treated water; and separating the sludge from the tertiary treated water in the solid-liquid separator followed by discharging final treated water while returning the sludge to the anoxic tank. According to this process, a load in a latter anoxic tank can be reduced, the anoxic tank can be downsized compared with the prior process and treated water with good water quality is stably provided.

Abstract: A non-limiting example method includes receiving a request to publish content that is stored on a user storage server in a personal data store. The method includes preparing the content for publication and moving the prepared content to a content repository to generate published content. The method includes receiving a request to make a personal copy of the published content and making a copy of the published content in a personal data store in a user storage server. The copy is independently editable of the published content. A non-limiting example system includes an application programming interface that includes a publish command to generate a published copy of a specified first content stored in a first personal data store in a content repository, and a retrieve command that generates a personal copy of a specified second content stored in the content repository in a second personal data store.
