Methods are proposed to define UE behavior for performing synchronization signal block (SSB) based radio link monitoring (RLM) and channel state information reference signal (CSI-RS) based RLM. In a first novel aspect, if CSI-RS based RLM-RS is not QCLed to any CORESET, then UE determines that CSI-RS RLM configuration is error and does not perform RLM accordingly. In a second novel aspect, SSB for RLM and RLM CSI-RS resources are configured with different numerologies. UE perform SSB based RLM and CSI-RS based RLM based on whether the SSB and CSI-RS resources are TDMed configured by the network. In a third novel aspect, when multiple SMTC configurations are configured to UE, UE determines an SMTC period and whether SMTC and RLM-RS are overlapped for the purpose of RLM evaluation period determination.

Wastewater containing a significant level of dissolved readily biodegradable organic compounds matter, such as short-chain fatty acids, and ammonia can be efficiently treated to remove most or all of the organic compounds and the ammonia, with the production of microbial storage compounds such as polyhydroxylkanoates, by (i) subjecting the wastewater storage compound-accumulating microorganisms (SCAM) in the presence of oxygen, (ii) subjecting at least part of the resulting partly treated wastewater to ammonia-oxidising microorganisms (AOM) in the presence of oxygen and (iii) feeding a gas containing molecular carbon dioxide produced during step (ii) to step (i) so as to lower the pH in step (i).

The present invention relates to a method for increasing the magnesium ion concentration of feed water. The method comprises the steps of providing an inlet flow of feed water (Q.sub.IN), increasing the concentration of carbon dioxide in said inlet flow Q.sub.IN to obtain a flow of carbon dioxide-containing feed water (Q.sub.CO2), and passing said flow Q.sub.CO2 through a solid bed comprising a magnesium ion source to obtain an outlet flow of treated water (Q.sub.OUT) having an increased concentration of magnesium ions. The invention further relates to a water treatment system for increasing the magnesium ion concentration of feed water and a corresponding flow reactor.

This disclosure relates to a method, system and apparatus for inactivating microorganisms in an aqueous solution. The method comprises passing bubbles of a gas through the aqueous solution, wherein the gas comprises at least 10% CO2 by volume and has a temperature of at least 18 C. The system comprises a gas supply to supply gas comprising at least 10% CO2 and having a temperature above 18 C., a gas-delivery apparatus to receive the gas and deliver it into the aqueous solution in the form of bubbles. The apparatus comprises a gas-permeable material having a flow surface configured to enable the flow of the aqueous solution across the flow surface, a chamber arranged at an opposite side of the gas-permeable material to supply a gas that inactivates microorganisms such that the gas is able to pass through the gas-permeable material and into the aqueous solution as gas bubbles.

Provided is a wastewater treatment process including: (a) circulating wastewater including biodegradable organic material, between an anaerobic digester (AD) and at least one microbial electrolysis cell (MEC), the MEC including an anode and a cathode; (b) applying voltage on said anode and said cathode; and (c) discharging from said AD biogas with a methane fraction of above 70% v/v. Also provided is a biological wastewater treatment system including wastewater inlet, and (i) an anaerobic digester (AD) comprising biogas outlet, and effluent outlet; and (ii) at least one microbial electrolysis cell (MEC) including an anode and a cathode; said AD and said at least one MEC being in liquid communication through liquid circulation lines configured for at least circulating wastewater between said AD and said at least one MEC.

The invention is an immersion system for decontamination of ship outer surfaces while a ship is located in a lock structure. The lock structure is modified with an inflatable bladder and shortened containment gates. When the ship enters or exits the lock structure, the inflatable bladder is deflated before opening the containment gates. When the inflatable bladder is deflated, a lower treated fluid layer sinks and water adjacent to the lock structure enters the lock through wall ports to create an upper fluid layer on which the ship enters. When the ship is located in the lock structure and the containment gates are closed, the inflatable bladder is inflated. When the inflatable bladder is inflated, the lower treated fluid layer rises and surrounds the ship surface to kill invasive aquatic species.

The invention provides methods and compositions for treating wash water from concrete production with carbon dioxide. The treated wash water can be reused as mix water in fresh batches of concrete.

A method and system for self-contained growth and harvesting of plant and animal foodstuffs and energy generation for terrestrial and non-terrestrial uses. The system can be self-contained and sealed from an ambient atmosphere wherein sufficient oxygen and carbon dioxide levels are maintained (bio-regenerative) to support human life. The system and method may utilize aquaculture and hydroponic plant growth with a digester for converting waste into nutrients. Water may circulate among the digester, aquaculture tanks and hydroponic growth tanks. The method may be scalable to support varying quantities of human life. The system and method may generate energy and consume greater quantities of carbon dioxide than generated. The system may be energy self-sufficient utilizing solar, wind or other energy sources such as generated methane gas.
