The Golder Associates laboratory facility in Vancouver, BC, conducts various
concrete sample core tests daily, including concrete crushing and sawing.
These tests ensure concrete used in developments throughout the greater
Vancouver area meet the designed and required strength specifications. This
testing produces a waste-slurry of fine concrete particles. If untreated, the
concrete sediment would add an unnecessary load and blockage concern to
the Vancouver water treatment system.
Initially, consultants were unaware of a cost effective technology to eliminate
the resulting waste concrete sediment load. Then, the Jellyfish Filter was
proposed. This facility wanted to achieve particulate removal down to the
5 micron level, which is accomplished by the Jellyfish Filter membrane
technology. The Jellyfish Filter membrane is easy to rinse and clean, and
operates from gravity flow making this a very simple and convenient solution.
The Jellyfish Filter stops the daily laboratory concrete waste sediment from
clogging the city’s wastewater treatment system by removing the very fine concrete particles prior to discharge. The system
design used multiple 15-inch lightweight membrane filtration cartridges. The cartridges are easily accessed at floor level by
opening a hatch in small precast vaults and are designed to treat a maximum 6.94 L/s (0.25 cfs).
Though commonly used for urban stormwater runoff treatment, the Jellyfish Filter was identified as a cost-effective waste water
treatment solution within the test facility. Its compact design, with unique gravity flow, requires no electric power to provide
the discharge treatment result. An additional benefit was the ease of access for periodic cleaning and rinsing. The small,
lightweight filtration cartridges are easily removed so the membrane can be rinsed, and then re-used keeping the operation and
maintenance cost to a bare minimum.
“We are extremely pleased with the quality of discharge to the sewer and simple cleaning
procedures,” noted Gary Fitzgerald, Equipment Coordinator at Golder Associates.
