BRINE INJECTION SYSTEM WITH IMPROVED FILTERING SYSTEM
A brine injection system with a plurality of needles, which are inserted into a product and through which brine is injected into the product. Brine which does not end up in the product is collected and recycled, and during recycling, the brine flows through a filter. The filter includes a filter element, along which unfiltered brine flows in a flow-direction and through which filtered brine passes and which holds back residues in the unfiltered brine. The filter element includes a multitude of slots, each with a main extension direction which extends parallel to the flow direction of the brine.
MULTI-STRUCTURE FILTRATION DEVICE FOR FILTERING, SEPARATING, AND DEHYDRATING FOREIGN SUBSTANCES IN WATER
The present invention provides a multi-structure filtration device for filtering, separating, and dehydrating foreign substances in water, the multi-structure filtration device comprising: a filtration tank filled with filtration target fluid inside; a filtration device unit having a cylindrical double drum structure, installed in the filtration tank so that a part of the filtration device unit is submerged in the filtration target fluid, and including two or more filters having different mesh sizes that are respectively wound on an inside and an outside of the filtration device unit, and one or more washing modules washing foreign substances attached to the filter wound on an outside of the filtration device unit. Accordingly, the multi-structure filtration device can have excellent filtration performance by double-filtering the target fluid using two or more filters, can operate in an eco-friendly manner by recycling filtered water and effectively washing the filters using the filtered water without separate chemicals, can increase the durability of the filters, and can reduce the washing and processing cost by reusing the filters.
SEPARATOR MONITORING AND CONTROL
A system for separating solids from fluids, the system including a separator having a deck having a feed inlet and a solids outlet and a plurality of screens disposed on the deck. Also, an image sensor disposed proximate the solids outlet, the image sensor to capture images of the separator, and send the captured mages to a remote location for analysis. Additionally, a method of monitoring a separator, the method including capturing an image of the separator and sending the image of the separator to a control module disposed at a remote location. The method also including analyzing the image with the control module to determine a separation property and modifying the operation of the separator based on the determined separation property.
Continuous rotary plate filter and methods of use thereof
The present disclosure provides for a continuous rotary plate filter apparatus and a method of using the apparatus to separate slurries into liquids and solids. The methods and apparatus are useful for the production of fine chemicals and pharmaceuticals, particularly using Integrated Continuous Manufacturing (ICM), but can also be integrated with other manufacturing processes, such as batch and semi-continuous processes.
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.
Controlling a separation device
There is described a system and a process for optimizing and controlling upstream fluid treatment processes using information on fluid characteristics obtained from response variables of a separation device (such as the belt speed or water level of an RBF). This system and process allow for the upstream or downstream treatment processes to be adjusted and optimized against the instantaneous operating conditions of the separation device such that both the pre-treatment and post-treatment processes and the separation system always run at an optimal efficiency. Additionally, since the information obtained from the response variables of the separation device truly reflect the fluid characteristics at the point where the separation system is installed, the same can be used to control a downstream process (for example, the amount of oxygen required in the biological oxidation stage or the sludge retention time in an side stream sludge treatment process such as fermentation or anaerobic digestion).
