Independant Studies of the Filtration System
A pre-filtration system, which will decrease the cleaning frequency and blockages of pipes, drains and grease traps. The units are installed before the drains or grease trap. The MOEE Sewer-Use by-laws regulate the Biological Oxygen Demand, Total Suspended Solids, Oil and Grease loading to the sewer system. Yearly loadings to the sewer system are expensive in the treatment of waste. Also this prefiltration system would reduce the amount of waste that would not be efficiently removed by the preexisting grease trap.Fisher Environmental tested the efficiency of the system in decreasing the above three parameters. Four restaurants in the Toronto area were sampled in the study. In most cases, the removal of total suspended solids, oil and grease were greater than 75%. The Biological Oxygen Demand (BOD) removal ranges from 40 to 90% depending on the restaurant's qualities. The optimum removal occured after the filter bag was preconditioned with solid particulate matter. Maxxam Analytics Inc.

An independent laboratory ran a series of tests for RHINO Ecosystems Inc. to test the waste water stream at five locations of kitchen sink drains for the following items: 1. Total Suspended Solids (TSS) 2. Biological Oxygen Demand (BOD) 3. Fats Oils and Grease (FOGS)Testing ports were put under the sinks in front of the Rhino units top entry port, after the Rhino units exit port, in front of the grease trap entry, and after the grease trap exit port to the city sewage system.A quick summary of the test results are as follows:After the Rhino unit TSS 85.53% Reduction BOD 80.03% Reduction FOGS 89.78% Reduction. After the unit and grease trap TSS 89.50% Reduction BOD 87.27% Reduction FOGS 92.37% Reduction
