摘要： This invention relates to apparatus, methods and applications for treating wastewater, and more particularly to a technique of biological processes that integrates lowering the levels of effluent pollutants and reducing accumulated sludge volume from wastewater. This invention further relates to apparatus and methods for using a blend of non-pathogenic microbes, spores, unicellular organisms, and enzymes on-site at a wastewater treatment facility to rapidly, ecologically, and cost-effectively solve numerous contaminant issues common in wastewater.

摘要： A method the filtering a liquid in a membrane filter immersed in the liquid and including membranes, the method including introducing a gas through a gas introduction device into a base of the membrane filter in successive pulses so that the membranes are cleaned wherein the gas introduction device includes a liquid flow channel which vertically penetrates a gas collection cavity and admits the liquid into a bottom of membrane filter; and initially filling a gas volume arranged below a free surface of the liquid and defined in a downward direction by an enclosed level of the liquid with the gas wherein the gas simultaneously displaces the liquid top down from a gas lifting channel until the enclosed level of the liquid drops below an inlet cross section of a gas flow out channel.

摘要： A filtering well has a body defining an inner volume, the body having a mineral membrane made of a pervious concrete composition in order to filter water flow into the inner volume of the body. An outlet conduit is in fluid communication with the inner volume for discharging water therefrom. The outlet conduit is formed in the mineral membrane of the body. Other aspects are also disclosed.

摘要： The invention relates to water regeneration in a fish breeding complex combining closed and flow-through water supply systems. A module of a biological filter in a water regeneration system comprises a reservoir, an aerator, a channel for sludge accumulation and discharge and a reservoir bottom sloped in direction of the water movement and, with the water surface, forming a diffuser providing for circulation of water and filler in the biological filter. Fish breeding complex comprises fish breeding pools and a water regeneration system comprising a mud settler-denitrificator, a device for water lifting and aeration, a biological filter, degassing and disinfection units. Each fish breeding pool comprises water oxygenation and disinfection systems, dosage units, water discharge systems and insoluble residues collecting and discharge systems. In the water flow-through mode, water regeneration system is switched off and water supply from an outside source and wastewater discharge are switched on.

摘要： A method for aerating water in a treatment basin includes positioning at least one bridge above an upper surface of the water in the basin; providing a retrievable mounting frame assembly; securing a guide rail assembly to the bridge; transporting the mounting frame assembly on a transport device to a selected position on the walkway near the guide rail assembly; securing a transfer crane to the walkway proximate the guide rail assembly; transferring the mounting frame assembly from the transport device for connection to the a one guide rail assembly; connecting the mounting frame assembly to the guide rail assembly to provide a supply of air to the first air distribution conduit; moving the retrievable mounting frame assembly from a first position above the upper surface of the water to a second position below the water; and initiating a flow of air to the first air distribution conduit.

摘要： A cord for supporting a biofilm has a plurality of yarns. At least one of the yarns comprises a plurality of hollow fiber gas transfer membranes. At least one of the yarns extends along the length of the cord generally in the shape of a spiral. Optionally, one or more of the yarns may comprise one or more reinforcing filaments. In some examples, a reinforcing yarn is wrapped around a core. A module may be made by potting a plurality of the cords in at least one header. A reactor may be made and operated by placing the module in a tank fed with water to be treated and supplying a gas to the module. In use, a biofilm covers the cords to form a membrane biofilm assembly.

摘要： A water filtering system includes providing light deep into a liquid used in applications such as the cultivation of both attached and suspended photosynthetic organisms. The system is configured to inject a stream of bubbles into the liquid and a light source is configured to shines light through the bubbles. The bubbles allow some light to travel deep into the liquid along the length of the bubble stream and scatter/deflect some light out of the bubble stream and into the surrounding liquid including screens for growing algae.

摘要： Systems for use in one or more sludge or waste collection devices (e.g., containers, vessels or basins). One such system is a sludge removal system for removing sludge from one or more sludge collection devices. The sludge removal system includes one or more sludge removal grids disposed in one or more sludge collection devices. Each sludge removal grid preferably includes at least one header and a plurality of sludge collection laterals. Another such system includes a fluid distribution system for distributing one or more fluids in one or more sludge or waste collection devices. A movement restricting or prevention member is provided in both the fluid distribution and sludge removal systems to prevent or restrict movement of the sludge collection laterals and the fluid distribution laterals away from or towards a floor of a corresponding collection device without anchoring or fixing the laterals to the floor.

摘要： A mixing aerator is disclosed that includes a housing defining a chamber having a bottom end and a top end, the housing having at least one inlet and at least one outlet; and a longitudinally extending diffuser disposed within the chamber and configured to deliver air bubbles into the chamber when the chamber is filled with liquid. The diffuser includes (a) a tubular elastomeric membrane having a plurality of perforations and, within the tubular elastomeric membrane, (b) an air pipe having a plurality of openings, the openings being larger and fewer than the perforations, and the tubular membrane having upper and lower ends that are sealed against an outer surface of the air pipe.
