摘要： Proposed is a process for collecting and removing microplastics in wastewater. The process includes coagulating microplastics in wastewater and adding an enzyme to the coagulated microplastics. Also, a method for collecting and removing microplastics is provided, the process comprising: pulverizing polyethylene terephthalate (PET) bottles into microplastics; dispersing the microplastics into a water system; coagulating the microplastics to produce coagulated microplastics; and adding an enzyme to the coagulated microplastics whereby the coagulated microplastics are decomposed by the enzyme into their monomer constituents. According to this process and method, the microplastics in wastewater can be removed with high efficiency.

摘要： A water purification system is disclosed which, includes a reverse osmosis (RO) system or component that is connectable to a city or other outside water feed that is capable of responding to and compensating for low or no feed water pressure coming into the RO system to ensure the outgoing supply of purified water is provided consistently and at a minimum water pressure. This can be accomplished without the need for communication with another device or system-wide facility, such as a hospital, or a pharmaceutical or semiconductor manufacturing system, requiring a constant water supply.

摘要： The present invention is a process, a method, and system for recovery and concentration of dissolved ammonium bicarbonate from a wastewater containing ammonia (NH3) using gas separation, condensation, and crystallization, each at controlled operating temperatures. The present invention includes 1) removal of ammonia from waste (sludges, semi-solids, and solids and liquids) without the use of chemicals at a temperature of at least 80 degrees Celsius, 2) condensing the gaseous containing ammonia, carbon dioxide and water vapor to remove water vapor concentrating the amount of gaseous ammonia and carbon dioxide, 3) concentrating the ammonia and carbon dioxide in the water by established means, such as concentrating the gas using partial condensation followed by passing the concentrated gas through an absorption column at a temperature of between about 20 and 50 degrees Celsius to form dissolved ammonium carbonate and ammonium bicarbonate, or total condensation followed by dewatering using reverse osmosis, and 4) crystallizing concentrated dissolved ammonium carbonate and ammonium bicarbonate at a temperature of less than about 35 degrees Celsius to form solid ammonium bicarbonate and ammonium carbonate.

摘要： In some embodiments, a method may include treating pulp in pulp and paper mills. The methods may include providing a peracetate oxidant solution and generating a reactive oxygen species. The peracetate solution may include peracetate anions and a peracid. In some embodiments, the peracetate solution may include a pH from about pH 10 to about pH 12. In some embodiments, the peracetate solution has a molar ratio of peracetate anions to peracid ranging from about 60:1 to about 6000:1. In some embodiments, the peracetate solution has a molar ratio of peracetate to hydrogen peroxide of greater than about 16:1. The peracetate oxidant solution may provide enhanced treatment methods of bleaching, brightening, and delignifying pulp fibers involving the use of peracetate oxidant solutions.
