NAME: Borough of Ramsey
LOCATION: Ramsey NJ, USA
DATE INSTALLED: 2008
DESCRIPTION:
The Borough of Ramsey is a local water authority. There are 6 well sites of differing sizes across the borough. The North Central site is a typical example; it takes feed from 2 wells, combines them and then the pH is adjusted. Following this the arsenic is removed using MEL´s ISOLUX media before going to a VOC stripper. Finally the water is chlorinated before leaving the site. This site demonstrates Isolux fitting into a system requiring several treatment stages.
CAPACITY:
This varies for each of the 6 sites. The North Central site has a flow rate of 225 gpm; treated for arsenic using 3 x 75 gpm Isolux modules. Each module has 18 cartridges split between 2 tanks. Another site, East Oak, is a space constrained situation, the Isolux system was modified to meet these challenges.
TYPE OF SYSTEM:
pH adjustment is used at each of the Ramsey sites; a flow meter adds carbon dioxide steadily, aiming to reduce pH from 7.8 to 7.2. Consumption at the large, North Central site is estimated at 10 lb of carbon dioxide per day.
INITIAL ARSENIC LEVEL: up to 10 ppb
TARGET ARSENIC LEVEL: < 5 ppb
ACTUAL ARSENIC LEVEL: below limit of detection
PERFOMANCE: Cartridges are changed at the North Central site approximately once a month. A SCADA system is used to keep track of the flow rates through each of the 6 sites. The bed volumes treated varies between each site from 2,275,000 to 11,000,000 gallons.
OTHER INFORMATION:
There are many considerations for water quality at this site: including pH control and VOC stripping. This example demonstrates the ability of the Isolux system to slot into an existing water treatment program and into space limited environments. Below is a case study summary of the Borough of Ramsey installation.
