A system configured to treat a wastewater stream collection system including a source of a treating agent, a metering valve, a sensor, and a controller operatively connected to the metering valve and the sensor. A non-transitory computer-readable medium including instruction that instruct a controller to perform a method of controlling addition of a treating agent into a wastewater stream collection system. A controller for a system configured to treat odor and control corrosion in a wastewater stream collection system that is operatively connectable to a metering valve for administering a treating agent to a wastewater stream collection system.

An agricultural processing system includes a process that uses water and produces wastewater having insoluble solids, a pump configured to receive and pressurize the wastewater from the process, and a plurality of centrifugal separators connected in parallel and configured to receive the wastewater from the pump. The separators are each configured to separate out the insoluble solids from the wastewater to produce a cleaned wastewater.

A reverse osmosis (RO) system is described that is connectable to a dialysis machine and is capable of using heated purified water to clean and disinfect an external connection section or portion disposed between the RO system and the dialysis unit (or any other external heat tolerant device) without forming a closed loop system between both systems before and during a heat forward process. This can be accomplished without the need for direct/indirect or wired/wireless communication with the dialysis unit or the need to introduce a chemical cleaner or process that would require further rinsing after chemical disinfection.

A treatment system and method for cephalosporin wastewater are disclosed. The treatment system includes: a flocculation and sedimentation device, an alkali reaction tank, a PAC reaction tank, a PAM reaction tank, a wastewater heat exchanger, a wastewater heater and an oxidation reactor that are connected with each other in sequence, wherein the wastewater heat exchanger is provided with a material inlet, a material outlet, a heat source inlet and a heat source outlet.

A digital twin model based operation and optimization of a reverse osmosis plant uses a data processing system to receive data for a reverse osmosis membrane in a plant that with a plurality of assets. The data processing system can determine a level of performance of the membrane based on the data for the membrane input into a model generated with sa topology indicative of one or more relationships and a flow path between the plurality of assets, predict, based on the model and responsive to the level of performance input into an optimization function for the plant, a time at which the level of performance degrades below a threshold, and provide an indication of the time at which the level of performance degrades below the threshold predicted using the optimization function to cause servicing of the membrane used to process the fluid at the plant.

Methods for treating phosphogypsum-containing water are disclosed. The water may be treated so as to promote precipitation of one or more target constituents and to facilitate downstream membrane treatment. A coagulant may be added to promote phosphate recovery. Ammonia may optionally be removed. Related systems are also disclosed.

A filtering time control method includes testing water quality to obtain a water quality status value, determining whether a current filtration meets requirements. Based on whether the current filtration meets the requirements, setting a duration of the next filtering based on the current filtration duration. Adaptive adjustment of the duration of filtration may ensure a filtering effect while saving water resources.
