Abstract
A method for the sampling one or all phases of batch sewage treatment process to obtain an accurate timing of completion of one or all of the phases of the batch sewage treatment process. The number and timing of samples taken is selected to provide samples over the length of a given phase or a group of phases or all phases of the batch sewage treatment process recommended by the manufacturer of the equipment. Samples are analyzed to determine the end point of the reactions in the phase being sampled. Based upon the results of the tests the sampling regime or the timing of the phase can be revised.
Claims24
A method for sampling a sewage treatment process in a sequencing batch reactor, said method comprising the step of synchronizing of one or all of the discrete phases of the sequencing batch reactor process with a sampling scheme to draw samples during one of, a selected, a selected group, or all phases of the sewage treatment process so that analysis of the samples will provide a true picture of the operating time for the selected phase or overall sewage treatment process.
A method for sampling a sequencing batch reactor sewage treatment process, comprising the steps of:
- (a) integrating a computer driver process control system with a sample system and an analysis system;
- (b) inputting a first set of operational instruction(s) to said sampling system to obtain samples from said batch sewage treatment process;
- (c) obtaining one or more sample(s) from said batch sewage treatment during one of a selected, a selected group of, or all phases of said sewage treatment process;
- (d) performing a screening evaluation to select one of, one or more sample to be analyzed for specific physical or chemical data;
- (e) inputting said physical or chemical data into said computer for comparison with data indicating said sewage treatment process in operating in accord with parameters suggested by the manufacture of equipment used to effect said sequencing batch reactor sewage treatment process;
- (f) using said computer to generate a new operational instruction based upon the results of said data comparison;
- and
- (g) inputting said new operational instruction to said sampling system to one of maintain said sampling regime or alter said sampling regime in order to obtain a true picture of operation of said sequencing batch reactor process.
A system for sampling a sewage treatment process in a sequencing batch reactor comprising in combination:
- an apparatus adapted to withdraw and hold samples of sewage from said sequencing batch reactor according to a regime inputted into said apparatus;
- a controller adapted to initiate and terminate sampling by said apparatus, said controller including first means to enable a user to input into said controller resettable count down timers for each phase of said sewage treatment process, said controller including resettable switches to enable or disable signals to said apparatus for withdrawing samples said switches set by an operator in accord with a desired pattern of sampling one of, a selected, a selected group, or all phases of said sewage treatment process;
- and
- said controller including indicators to indicate beginning of a sequencing batch reactor treatment cycle.
A control system for a sequencing batch comprising in combination:
- means to enable a user to input into resettable count down timers in said means for each phase of a treatment process conducted by a user of said sequencing batch reactor, said means including resettable switches to enable or disable signals to an apparatus adapted to withdraw and hold at least one of a single sampler or multiple samples of sewage from said sewage treatment process, said switches set by an operator in accord with a desired pattern of sampling one of, a selected, a group, or all phases of said sewage treatment process;
- and
- indicators to indicate beginning of a sequencing batch reactor process cycle.
A method for modifying the control system for a sequencing batch reactor comprising the steps of:
- installing means to enable a user to input into resettable count down timers in said means times for each phase of a treatment process conducted by a user of said sequencing batch reactor, said means including resettable switches to enable or disable signals to an apparatus adapted to withdraw and hold at least one of, a single sample or multiple samples of sewage from said sewage treatment process, said switches set by an operator in accord with a desired pattern of sampling one of, a selected, a group, or all phases of said sewage treatment process;
- and
- installing indicators to indicate beginning of a sequencing batch reactor process cycle.
