GPHC to process its own drinking water
At a cost of $31M, the Georgetown Public Hospital Corporation (GPHC) will start processing its own drinking water with its newly installed treatment plant.
The water treatment plant.
Kamal Haricharan, the hospital’s Maintenance Manager in an interview with this publication said that by this weekend, the institution will be utilizing the water from its processing plant.
He noted that the treatment plant is fully operationalized. A shed was recently built to cover it.
Haricharan said that on Thursday, the quality of the purified water will be tested by the Food and Drugs Department before the facility starts to distribute it to various departments.
“It is a 5000 litre per hour water purification system. It can complete more than one cycle per day; it all depends on the demand for purified water and it is a multi-stage purification system,” the Maintenance Manager said.
He added that there are several stages in treating the raw water (water coming directly from the Guyana Water Inc. (GWI)’s lines).
There is a holding tank to store the raw water and there is another tank to store purified water.
Haricharan explained that once the water leaves the raw water holding tank, it passes through the sand filters, carbon filters, softening particle filters, reverse osmosis and ultra violet filtration before it goes into the holding tank.
The sand filters are the main workhorses of the water purification system. When the source water seeps through these filters, it is cleaned in two different ways.
First the sand works like a sieve, straining out harmful bacteria.
Clean sand is negatively charged and works like a magnet attracting positively charged particles in the water.
These particles in turn attract more negative particles, which makes it even harder for bad bacteria to pass through the filter.
The more junk the filter collects, the easier it is to strain unwanted particles from the water.
Carbon filtering uses chemical adsorption to remove contaminants and impurities from the water, while water softening is the removal of calcium and magnesium in raw water.
The Maintenance Manager said that this new move by the institution will help to save a lot of money in the “long-run.”
