Compact High Throughput Filtering Systems for Wastewater

A system suitable for converting wastewater to a primary output of clear water and. a secondary output of concentrated sludge, the system occupying a rectilinear space of volume VS, wherein the system is configured such that, for wastewater having a total suspended solids (TSS) content of TSS1 and a chemical oxygen demand (COD) of COD1;

• the system receives, the wastewater at, a flow rate F1 and provides the primary output at least in part while receiving the wastewater;
• the primary output has a flow rate F2, where F2 is at least 40% of F1;
• the primary output has a TSS of less than 1% of TSS1, a COD of less than 2% of COD1, and a turbidity of less than 1 NTU;
• and
• VS is at least 5 m3, and F1/VS is at least 0.2 hr−1.

A filtering system suitable for converting wastewater to a primary output of clear water and a secondary output of concentrated sludge, the system comprising:

• a debris management (DM) section having a DM input, a DM filtered output, and a DM concentrated output;
• a first filtration section having a first input, a first filtered output, and a first concentrated output;
• and
• a second filtration section having a second input, a second filtered output, and a second concentrated output;
• wherein the first input couples to the DM filtered output, and the second input couples to the first filtered output;
• and
• wherein the primary output is the second filtered output.

A filtering system suitable for converting wastewater to a primary output of clear water and a secondary output of concentrated sludge, the system comprising:

• a debris management (DM) section having a DM input, a DM filtered output, and a DM concentrated output;
• a first filtration section having a first input, a first filtered output, and a first concentrated output;
• a second filtration section leaving a second input, a second filtered output, and a second concentrated output;
• a tank;
• and
• an electronic control system configured to control fluid flow through the DM module, the first filtration module, and the second filtration module;
• wherein the electronic control system is configured to operate the system in a first mode wherein the DM filtered output from the DM section is received by the MF section, and the first, filtered output from the MF section is received by the tank, and contents of the tank are directed to the RO section;
• and
• wherein the electronic control system is configured to operate the system in a second mode wherein the DM section and the RO section are fluidly isolated from the MF section, and the contents of the tank are received by the MF section, and the first filtered output from the MF section is received by the tank.
