Anaerobic decomposition of sludge - by directing sludge stream by nozzle into vertical venturi pipe and circulating and mixing sludge in container

A new procedure for anaerobic decomposition of sludge has the following stages: filling a container with sludge to above the upper end of a vertical rising pipe whose open upper end is a little below the roof of the container and whose open lower end is a little above the floor of the container; maintaining the sludge at a temp. which is suitable for decomposition; delivery of a stream of sludge under pressure into the container via an upward-pointing nozzle located below a venturi section built into the lower part of the rising pipe, so that a suction is created at the entry to the rising pipe and a flow of sludge upwards through this pipe is maintained and the incoming sludge and the sludge in the container are thoroughly mixed. The container has a wide centre section and tapers towards the top and bottom. Partly treated sludge may be withdrawn from the container and returned to it via the upward-pointing nozzle, or raw untreated sludge (144) may be introduced via. the nozzle. The sludge may be pressed through a heat exchanger by the pump entering the nozzle, in order to regulate its temp. USE/ADVANTAGE - Used for anaerobic decomposition of sludge. Energy consumption is reduced and a high degree of mixing is acheived, and the appts. is relatively simple and is suitable for withstanding the harsh conditions which normally prevail inside composting containers.

Modular individual wastewater nutrient removal system

A modular, on-site, wastewater treatment system removes total nitrogen, phosphorus, BOD, and TSS. A flow equalization module provides a constant flow rate to the system eliminating the adverse effects from variations in flow rate throughout the day. Treatment modules are similarly sized to provide a compact, modular system. The nitrification module is a fixed-film, flooded packed bioreactor to facilitate bioconversion of ammonia to nitrate. Aeration of the module provides the oxygen needed for the bioconversion as well prevents clogging of the film. Solids from the nitrification process are removed in a first cone-shaped settling tank. De-nitrification where nitrate is converted to nitrogen gas takes place in an anaerobic fixed-film bioreactor. Carbon-based bio-film carriers provide a carbon source for de-nitrification. A final cone-shaped settling tank separates solids from the treated wastewater. Additional modules to address removal of phosphorous or other contaminants can be added to the modular system.

Advanced wastewater treatment process using up & down aerobic??anaerobic basin of channel type in a unit basin with recycle

A process for advanced wastewater treatment which reduces an energy cost by allowing wastewater to flow continuously, removes most of odor generated in a channel type anaerobic tank in an aerobic tank, minimizes the influence of the temperature drop of water in the wintertime, and improves denitriding and dephosphorizing efficiencies is provided.

Aeration of wastewater ponds using airlift pumps

The subject of this invention is a submerged airlift pump using multiple concentric pipes with diameters that increase as they near the water surface. Water initially accelerated into the lowest pipe section is progressively decelerated in subsequent pipe sections, increasing the residence time of the bubbles and hence the total driving force of the pump. Pipe proportions are optimized with gas flows to maximize total pump discharge at extremely low pumping-heads, resulting in ultra-high pumping efficiencies. This device can be used to promote circulation of large volumes of deep pond water, deficient in oxygen, to the surface, creating an increase in the exchange of gases between the atmosphere and water with minimal energy requirements.

Vessel has an inlet for the liquid to be treated and an outlet for the treated liquid. The liquid is stirred and gas introduced by a venturi ejector arranged a little below the level beneath which the suspended materials normally rest with the lower opening of its outlet cone directed towards the bottom of the vessel. Pref. the opening is about 50 cm above the bottom. The outlet cone may be vertical, pref. co-axial with the vertical axis of the vessel, and an upright solid cone may be located on the bottom of the vessel also co-axial with said axis. As well as purifying waste water by oxygenation, for example as in a known activated sludge process, appts. can be used for any process in which a liquid contg. suspended solids is to be treated by intimate contact with a gas so as to obtain e.g. after decanting, the deposit of the solids. Appts. avoids the risk of blocking of the pump in the ejector, after a period of shutdown, by settlement of the solids and is less affected by sudden changes in liquid level. The gas dispersion is more efficient.

Nozzle is supplied via a throttle valve with liq. by a motor-pump in a separate balance tank in which the level of liq. is regulated by the pump being switched on and off by low and high level of electric float switches. The balance tank pref. receives incoming liq. to be purified as well as recycled sludge from the clarifying tank of the installation and liq. recycled from the oxidation tank. The nozzle pref. has in internal pipe delivering compressed air into the jet. Aeration and agitation of waste water to be purified in the oxidation tank of an activated sludge plan. Aeration and agitation by means of an impeller jet is effective, simple and inexpensive. Intermittent operation of the motor-pump is effected by the rise and fall or level in the balance tank.

Submarine discharge of effluents through the thermocline - by means for entraining compressed air

To enable the effluent to pass through the thermocline, gaseous current is injected into the effluent at the submarine out by a current of compressed air from a pipe which may either be outside or inside the outlet pipe. The ascending gaseous current entrains the stream of effluent through the thermocline layer and causes it to diffuse into the layer above the thermocline and ultimately spread out over the sea in thin layers where its purificn. is completed under a acceptable conditions. Installation costs are low and since the operation is only seasonal, the running costs are moderate. The serious effect of the effluent reaching the coast during the hot summer season, when the thermocline forms, is avoided.

APPARATUS AND METHOD FOR THE BIOLOGICAL TREATMENT OF WASTE WATER

L'appareil de traitement biologique d'eaux résiduaires selon l'invention comprend, dans une seule cuve 10, une zone 38 de réaction biologique et une zone 40 de clarification, un dispositif 18 d'oxyhénation et des moyens pour maintenir une circulation d'eau dans la zone de réaction biologique, un déversoir 16 permettant au liquide clarifié d'être évacué par la canalisation 17 au même débit que celui auquel l'eau résiduaire pénètre dans le dispositif par la canalisation 13. The apparatus for biological treatment of waste water according to the invention comprises, in a single tank 10, a zone 38 for biological reaction and a zone 40 for clarification, an oxyhenation device 18 and means for maintaining a circulation of. water in the biological reaction zone, a weir 16 allowing the clarified liquid to be discharged through line 17 at the same rate as that at which the waste water enters the device through line 13.
