Abstract: There is provided a method for controlling bio-slimes in a clean circulating water system through a physical-chemical-superconducting high gradient magnetic separation coupling process. An inorganic composite flocculant is added to circulating water to gather Zoogloea in the circulating water with micro-nano particles in hydrosol through demulsification to form alum floc. The resulting water passes through a superconducting high gradient magnetic separation system. A magnetic field strength of the superconducting high gradient magnetic separation system and flow rate of the circulating water are controlled to generate strong magnetic flocculation to allow floc to grow, such that the Zoogloea in the circulating water wraps the micro-nano particles to separate the Zoogloea from water.

Abstract: A solar distillation system includes solar panels, and receivers adjacent the solar panels to receive process water to be processed to purified process water. The process water flows from a first receiver to a last receiver and is heated by reflected sunlight. Vapor tubes are coupled to the receivers, with each respective vapor tube coupled between adjacent receivers. Water vapor is generated as the process water is heated within each receiver. The water vapor flows via the respective vapor tubes between the adjacent receivers towards the last receiver. A return vapor tube is coupled to the last receiver. A distillation tube is coupled to the return vapor tube to receive the water vapor. The distillation tube extends through the receivers from the last receiver to the first receiver. As the water vapor travels through the distillation tube it changes to a liquid, with the liquid being the purified process water.

Abstract: A liquid solid separator tank has a motor driven recirculating belt having rollers placed therein processing a mixture of materials. The top belt brings wet materials into a collection trough having overflow weirs disposed externally. These weirs permit overflow liquids to flow down towards a main tank; then, a sump pump reintroduces water back into an influent basin to cleanse the mixture once again. Also, the action of a motor driven auger within the trough forces solids towards a dewatering box attached externally thereto. This box has a motor driven rotating cage mounted on moveable rollers and internally attached removable brushes that act to clean the outer surface of the cage as it moves in addition to a stationary high pressure wash. A shroud channels the influent liquid solid mixture towards a filtered water basin disposed directly underneath the lower belt portion permitting cleansed water to be removed therefrom.

Abstract: Hygiene regulations and social distancing are very effective in blocking short distance infections. During the lockdown, the distance rules can usually be adhered to, but what happens when the actual lockdown is over and the people meet again in a confined space? Then additional effective and efficient protection is essential to stabilize infection rates. Since the viruses are spread by contact and droplet infection, technical devices are required that effectively intervene in the chain of infection and effectively block infection. An effective protection is the respiratory mask as known since 100 years. An alternative to mask is an aerosol protection system for various applications in environment. The protection system consists of adjustable air sucking device and air blowing device in different form factors based on application. The aerosol protection system uses either an air curtain or air shield to prevent the aerosol going from one side of the curtain or shield to the other side.
