The purpose of the present invention is to provide a method for evaluating the clogging of a filtration membrane with a protein-containing solution, including the steps of: a) passing a protein-containing solution through a filtration membrane, b) after the step a), obtaining a filtration membrane cross-section from the filtration membrane, c) treating the protein-containing solution before the step a), the filtration membrane before the step b), or the filtration membrane cross-section after the step b) with at least one stain specific to a protein aggregate, and d) confirming the presence of the protein aggregate in the filtration membrane cross-section.

Waste gas mixtures produced and used in industry may contain harmful sulphurous compounds. The present disclosure provides a method for treatment of gas mixtures contaminated with harmful sulphurous compounds by using microorganisms capable of degrading said harmful sulphurous compounds which involves controlling nitrate levels in the medium in which microbiological conversion of harmful sulphurous compounds takes place at high levels.

A method for simultaneously removing high-load sulfur dioxide and nitrogen oxide in waste gas, relating to the technical field of industrial waste gas purification by biological methods. According to the method, the waste gas is led into a simultaneous desulfurization and denitrification packing tower and removed, microbial floras for simultaneously removing the sulfur dioxide and the nitrogen oxide are loaded on fillers of the packing tower, and the molar concentration ratio of the sulfur dioxide to the nitrogen oxide in the waste gas is (0.76˜1.06):1.

A device for recovering polluted air is disclosed. The device includes air collecting part, a main control part, a discharging part, and an air sending pipe. The air collecting part includes a cover body, a lower side of which is opened, and a filter member attached to an inside of the cover body. The main control part includes a pump capable of sucking and delivering gas. The discharging part including an air storage container to be installed in the sea. The air sending pipe couples between the air collecting part and the main control part and between the main control part and the discharging part to permit movement of the gas between the parts. The gas that is polluted air is sucked from the air collecting part by the pump and is delivered to the discharging part, and the gas is discharged from the air storage container into the sea.

A Kurthia gibsonii strain EO-06 with Deposit Number of CGMCC No. 18436, a Clostridium kogasensis strain EO-08 with Deposit Number of CGMCC No. 18438 and a Clostridium acidisoli strain EO-09 with Deposit Number of CGMCC No. 18439 are provided. The above strains can be used to treat pollution, for example, to treat industrial gas or wastewater containing ethylene oxide, which greatly improves the decontamination disposal capacity of ethylene oxide in industrial production. The present disclosure also provides a degradation agent for degrading ethylene oxide and a method for biodegrading ethylene oxide.

A mobile emissions control system having an emission capturing system and emission control system is provided for diesel engines operated on ocean-going ships at-berth. The emissions control system may be mounted on a towable chassis or mounted on a barge, allowing it to be placed alongside ocean-going ships at-berth. A crane or boom transfers a duct of the emissions capturing system extending from the emissions control system to the ship to capture exhaust from its engine. Alternatively, the system may be mounted on an automated guided vehicle (AGV) equipped with a tower and a crane. The crane mounted on the AGV then lifts the duct forming part of the emissions capture system to the ship's exhaust system to capture exhaust from the ship's diesel engine and transfers it to the emissions control system, which cleans the exhaust and then passes clean air into the atmosphere through an exhaust outlet.

The present disclosure relates to methods and systems for algae cultivation including the integration of electrochemical carbonate production for enhancing algae growth. More particularly, the present disclosure relates to methods and systems for producing a sodium hydroxide from brine using an electrochemical cell, contacting the sodium hydroxide stream with a CO.sub.2 gas sweep and producing a carbonate stream, and cultivating an algae slurry in a cultivation vessel comprising at least a portion of the carbonate stream.

The invention relates to a biofilter for biologically cleaning a waste gas stream containing contaminants, having at least one filter module through which the waste gas stream is to flow. The filter module has at least one filter layer containing an organic filter material, and the at least one filter layer being supported by at least one grating structure which is in particular oriented at least substantially horizontally. According to the invention, so that the biofilter can be operated cost-effectively, with low effort and with a high filtering efficiency over the longest possible period, the at least one grating structure formed by elongate grating elements which are arranged at least substantially crosswise and are in particular oriented at least substantially horizontally.

A bio-barrier for reducing combustible gas emissions from the ground into the atmosphere is disclosed. The bio-barrier includes a geocomposite layer extending laterally beneath a top surface of the ground and a first geotextile layer extending laterally beneath the top surface of the ground and positioned above the geocomposite layer. The geocomposite layer and the geotextile layer configured to laterally disperse the combustible gas through at least the geotextile layer. In addition, at least one sensor may be positioned beneath the top surface of the ground and in or above the geocomposite layer, the at least one sensor measuring a parameter indicative of the concentration or oxidation of the combustible gas beneath the top surface of the ground.

The invention includes systems, methods, compositions, and processes for designing, manufacturing, and utilizing carbon dioxide-sequestering substrates that can fully or partially replace natural sand in coastal engineering applications. These engineered substrates can offset demand for scarce native sand resources, while also effecting the conversion of gaseous carbon dioxide to dissolved or solid-phase products thereby offsetting impacts of anthropogenic climate change.
