Antimicrobial application system with recycle and capture

A capture unit for use with an antimicrobial application unit may include an upstream filter and a downstream filter. The upstream filter may be positioned to receive effluent from the application unit and to filter solid components from the effluent. The resultant upstream effluent filtrate may then be passed downstream to the downstream filter. The downstream filter may be used to filter an antimicrobial component from the upstream effluent filtrate and the resultant downstream effluent filtrate may be suitable for disposal as wastewater discharge. The antimicrobial is preferably a quaternary ammonium compound, is more preferably an alkylpyridinium chloride, and is most preferably cetylpyridinium chloride.

An incised surface is formed in one surface of a suction plate on the basis of a slit and a pattern roller is placed in a room, which is provided at a thickness part of the slit in which the incised surface is formed, to rotate in place so that the pattern roller partially protrudes outward from the incised surface and forms patterns on a surface of fleeces which are backwashed while passing through the slit so as to increase a filtration area of the fleeces. The backwash may be performed and the filtration area of the fleeces may be increased using the room. The spline-shaped patterns including splines cut to a certain length, patterns including several annular protrusions formed on an outer circumference of the pattern roller, spline-shaped patterns formed on the outer circumference, lattice-shaped patterns, and the like may be formed on a surface of the pattern roller.

Liquid solid separator

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.

Optimization of rotary filters relative to risk of clogging a facility for pumping water from a natural site

In the management of a facility pumping water from a natural environment containing impurities, the facility makes use of at least one rotary filter purifying the pumped water while some impurities at least partially clog the rotary filter. In particular, provision is made for estimating an evolution over time of a pressure loss caused by impurities clogging the rotary filter, based at least on data relating to the natural environment, dimensions of the rotary filter, and local measurements relating to at least one water level N.sub.amont upstream of the filter and to a flow rate of water Q.sub.aspiré drawn in downstream of the filter. Such an estimate of the evolution over time of the pressure loss makes it possible to anticipate possible risks of insufficient water supply to the pumping system (POM) downstream of the filter (FIL), or even to design filters (FIL) adapted to the needs of specific pumping facilities.
