A cartridge for extracting a beverage from a particulate substance contained therein by means of water under pressure is provided. The cartridge comprises a main body with a cup portion and a lid portion. The cup portion comprises a base, a sidewall and a rim opposed to the base, while the lid portion is fixedly attached to the rim of the cup portion so as to define an internal volume of the cartridge. The internal volume of the cartridge houses the particulate substance comprised within filtering means for retaining the particulate substance and for percolating fluid substances therethrough. The lid portion comprises a lid port defining a first passage for percolation fluid substances, the base of the cup portion comprising a cup port defining a second passage for percolation fluid substances. The cartridge further comprises a disc of porous material arranged between the filtering means and the base of the cup portion, so as to support the filtering means and the particulate substance and to define a fine canalization between the filtering means and the cup port.

The present invention provides a method for estimating an amount of immobilized probes, including the successive steps of: providing a sample on a substrate to form one or more spots of the sample on the substrate, the sample containing particulate substances and probes in a predetermined ratio, the probes being reactive with a predetermined target; measuring the number of the particulate substances contained in at least one of the spots; and estimating the amount of the probes contained in the at least one of the spots from the thus measured number of the particulate substances.

This application discloses a method for preparing tree whitening agent from solid waste, which uses shells, eggshells, broken glass, waste ceramic polishing powder, and desulfurization ash as raw materials from a wide range of sources and low cost, and is prepared by a one-pot firing process. Film formers and cellular glass. The formulation of the whitening agent is composed of lime and biological glue as film-forming substances, foam glass as thermal insulation material, and the hydration product is solidified with CO 2 , Adsorbs particulate matter in the air and has bactericidal and insecticidal properties. Eggshell-loaded MOFs photocatalysts degrade sulfur dioxide in the air under natural light conditions. In order to increase the strength of the whitening agent after hardening, it is mixed with sugar water. The preparation method of sugar water is to boil the water of sweet potatoes at high temperature. It has the social and environmental benefits of protecting trees, ensuring public safety, and purifying the air.

The invention relates to a waste gas treatment device, which belongs to the technical field of environmental protection equipment, including a turbulent mixing dust removal device, a drying device, a pre-filter, a zeolite runner concentration device, a fan I, a chimney, a heat exchanger, and a rotary RTO incinerator Device, blower II, the present invention pretreats the waste gas through the turbulent mixing dust removal device installed in front of the pre-filter, removes the particulate matter in the waste gas, and then filters the residual dust in the waste gas through the pre-filter In this way, it can avoid frequent replacement of the filter material of the pre-filter, and avoid the clogging of the zeolite runner concentrator due to the poor filtering effect of the pre-filter; at the same time, the present invention is to process the gas in the adsorption area of ​​the zeolite runner As the cooling gas in the cooling zone, avoid using the original exhaust gas as the cooling gas, which will cause the zeolite runner to absorb certain organic harmful substances when it reaches the cooling zone, and cause the adsorption capacity of the zeolite runner to decrease when it reaches the adsorption zone, resulting in excessive harmful substances in the exhaust gas.

A process for washing a particulate substance comprising: (i)combining a particulate substance and a first washing medium in a first vessel to form a slurry and washing the particulate substance with said washing medium; (ii)transferring the slurry to a hydrocyclone; (iii)removing a first by-product stream depleted in particulate substance and a first product stream enriched in particulate substance from the hydrocyclone; (iv)transferring the first product stream to a second vessel and in the presence of a second washing medium forming a slurry and washing the particulate substance with said second washing medium e.g. by agitation thereof; (v)transferring the slurry to ahydrocyclone; (vi)removing a second by-product stream depleted in particulate substance and a second product stream enriched in particulate substance from the hydrocyclone.
