GeoPool

An IMS Model 5012 LP Versi-Dredge pumps directly into a GeoPool next to a river in Europe.

The customer used the GeoPool to replace a $600,000+ dewatering system that could not remove the organics. The GeoPool solved the problem for less than 20% of the price of the dewatering system with zero polymers.

A GeoPool is almost at capacity and ready for dry down.

DEWATERING

An IMS Model 5012 HP Versi-Dredge pumps into a GeoPool in the United States. Note the active dewatering on the right hand side of the pool. A GeoPool can release several thousand gallons per minute.

A US contractor uses a GeoPool to dewater clay slurry. Due to the ultra fine particle size a polymer was used to speed up dewatering and improve clarity of the effluent due to strict site requirements.

DUMP DOORS

IMS’s patented GeoPool Dump Doors allow the operator to bulk release thousands of gallons of water from the pool after the solids have fallen out of suspension. No other comparably priced system can release water at a higher rate from a dredge discharge site.

This speeds up the dewatering process. Expensive mechanical systems and geotextile tubes require 100% of the water to go through the process and keep the slurry in higher turbulence so it cannot settle quickly and naturally like the IMS GeoPool which does not require expensive polymers.

DRY DOWN

An IMS GeoPool after several days of drying down is ready for the IMS patented Collapsible Clean Out Gate to be lowered and the excavator to remove the dry solids and prepare for the next filling. This particular pool took over a week to fill and 3 days to dry down.

A customer stands on top of the material during the dry down phase to show how compact the dry sediment has become after less than 72 hrs. Results will vary depending on material and temperature.

CLEAN OUT

A GeoPool is cleaned out with a back hoe after the dry down phase. Most customers will purchase a second GeoPool so they can continue to pump while the first GeoPool is cleaned out.

Note the level of dryness and no material is sliding away from the dewatered cake.

IMS’s patented Collapsible Clean-Out Gates allow excavators to quickly clean out a GeoPool and stockpile dry caked material near by for hauling away.

EFFLUENT

The bottle on the left shows a quick draw sample of bentonite material slurry. The two bottles on the right show two samples of the effluent released from the IMS GeoPool filter fabric. Independent lab test results showed 200-225 total suspended solids (parts per million) when working with this fine material slurry. This is after zero treatment with polymers or flocculants. Different material types will yield different dewatering rates and clarity.
