Title: Pneumatic timer at ambient air pressure - is for reversing pump and uses bellows fixed to piston, having controlled air bleed rate to delay reversing of bidirectional valve
IPC: F01L27/04
Filed: 1981-07-02
Abstract: The pneumatic pump controller comprises an actuating rod driven by a piston, a bi-directional control valve, and a controlled delay timer for the interval between forward and reverse strokes. The valve (10) admits air initially to the left side of a piston in a cylinder (14). The piston moves to the right to draw fluid from a reservoir (32) into the left hand chamber of the cylinder. At the same time, a link (38) fixed to the piston rod (28A) slides along the piston rod (52) of the timer (44) till it reaches a stop (58). Further piston motion draws a vacuum in the bellows (42) attached to the timer piston (50) and also displaces the bidirectional (10) valve from one detent stop to another (80), reversing the direction of compressed air supply to the piston so it immediately commences to move to the left, forcing the fluid in the left chamber out (83). Air is meanwhile allowed into the timer bellows at a controlled rate. The timer piston (50) is forced back against the air in the bellows (42) by a spring (56) and as it returns the linkage (56) from the timer piston rod to the bidirectional value forces this valve in the opposite direction to recommence the cycle.

Patent NL-9101917-A (NL)
IPC: C02F3/30
Filed: 1991-11-18
Abstract: The invention relates to a method for the treatment of (raw) sewage in a package plant consisting of three bioreactors in series. The treatment is being carried out using three types of biomass. In a first step (3,4) phosphate is removed by biological means and, at the same time, the chemical and biological oxygen demand is lowered in a highly loaded active sludge system, in a second step (10) a nitrification is carried out, ammonium being converted to nitrate, and in a third step a denitrification (12) is carried out using a carbon source. In the denitrification step acidified surplus sludge from the P-removing step can also be used instead of an external carbon source. The nitrifying and denitrifying bioreactors are both fixed film processes. The thickness of the biofilm on the support material in the nitrifying bioreactor can be influenced by adjusting the aeration system or by adjusting the hydraulic loading. In the denitrifying bioreactor the thickness of the biofilm can be adjusted by raising the shear by means of raising the superficial velocity in the support material. The system according to the invention makes possible effective treatment of raw sewage in a highly loaded system resulting in the far-reaching removal of COD, nitrogen and phosphate. The process can be operated in an alternative mode, where the nitrifying and denitrifying bioreactors are exchanged; first bioreactor: biological-P-removal and simultaneous reduction of COD, second bioreactor: denitrification and third bioreactor: nitrification. The effluent of the nitrifying bioreactor is recirculated to the denitrifying bioreactor. The first step is carried out in a plug flow bioreactor with an anaerobic and an aerobic zone. By using an intermediate settling tank (5) between the first and the second step, it is possible to discharge phosphate-rich surplus sludge. The mixing in the nitrifying step is advantageously maintained by aeration under the packages of support material. Mixing in the denitrifying step is accomplished by means of a propellor. <IMAGE>

Title: Collecting phyto- and zoo-plankton or purifying waste water - by using granular bed to flocculate microscopic particles in suspension
IPC: C02F/
Filed: 1983-05-02
Abstract: Process for flocculating microscopic particles in suspension in a liquid is disclosed. The suspension is passed through a fixed, granular filter bed until the bed becomes noticeably obstructed by retained particles. The bed is then at least partially cleared by flushing through with a second liq. The second liq. is passed through the bed in the same direction as the suspension but at a higher speed. Downstream of the bed, the flocculated particles are accumulated separately from a clarified effluent. Pref. the second liq. also contains microscopic particles in suspension. The second liq. is pref. the same as the liq. of the first suspension. Pref. part of the clarified effluent is recycled with suspension entering the filter bed. Pref. all liq. flows upwards through the filter bed. The speed of flow of second liq. through the granular bed is pref. between 0.1-5 m/h. The granular material pref. has a density of about 1.1 g/cu.cm and a grain size between 0.005 and 3 cm. A partic. preference is calcined clay ground to a grain size between 3-5 mm. The process is for collection of microscopic, living particles from natural waters, esp. phyto-plankton and zooplankton for use in foods, medicines or in fermentation to produce methane. The process can also be adapted for the purificn. of waste water. Compared with previous concn. rates of 20-30 times, the new process offers a concn. rate of around 100 for plankton etc. without alteration of nutritional qualities. In the purificn. of waste water, flocculation is now effected without treatment agents.
