Abstract
A method for creating a filtration knowledge base is used in a filtration process for separating a liquid component and a solid component from a slurry. The concentrations of the solid component in the slurry, and of the solid component in the separated liquid, are monitored and stored in a knowledge base along with a quantity relating to the amount of filtering. The knowledge base can be used for controlling the slurry-producing process, routing the separated liquid, automated billing and automated compliance reporting.
Claims8
An automated monitoring, controlling and record-keeping process adapted for monitoring and controlling a cross-flow filtration process that receives a slurry from a slurry-producing process, the slurry having a liquid component and a solid component, the filtration process acting to separate the solid component of the slurry and the liquid component of the slurry, comprising the steps of:
- monitoring an amount of filtering performed, using a first sensor to create a first signal, based on at least one of:
- the flow of slurry into the filtration process, the flow of liquid component from the filtration process, and the amount of solid component separated from the filtration process;
- monitoring a concentration of the solid component in the separated liquid component using a second sensor to create a second signal;
- creating a record including a second entry generated by comparing a value of the second signal to a compliance value and including a first entry based on the first signal;
- transmitting the record to a central station;
- and controlling at least one parameter of the cross--flow filtration process.
