Bartica Water Supply Rehabilitation Project

The Bartica Water Treatment Plant, located on the bank of Essiquibo River, is a 3.5 MLD treatment plant supplying treated water to a locality of approximately 12,000 people. The treatment plant draws water from the Essiquibo river. The water is characterized by high color & iron content, mediocre turbidity and extremely low pH & alkalinity. To make the river water potable (within the World Health Organization's drinking water standards) the following process units were included in the treatment scheme:

On line static mixer for adequately mixing the chemicals
2 Nos. solid contact clariflocculators each with sludge scrapping mechanism and a flocculation zone with a turbine mixer
2 Nos. dual media pressure filters
500 M³ chlorine contact / reservoir tank
Chemical dosing system comprising of lime, alum & polymer dosing facilities
Chlorine dosing facilities for disinfection

The following eletro-mechanical equipment was installed in the project:

2 Nos. 40 lps raw water pumps
3 Nos. 20 lps booster pumps
2 Nos. backwash pumps
2 Nos. air blowers
1 No. service water pump
Chemical dosing pumps, mixers and tanks
Chlorine dosing system
