Palgey Maim performed an engineering survey for a SEAPAL water company in Puerto Vallarta – Western Mexico, to analyze its water sources.
The survey included the water and sewer networks as well as the wastewater treatment plants.
The water supply system in the city is in crisis in terms of available water, and a number of issues were identified, which must and can be solved.
Palgey Maim proposed the development of alternative water sources in short time-frames by operating existing wells that are not in use, and which had been polluted as a result of high concentrations of iron (Fe) and manganese (Mn).
In order to remove iron and manganese, there are technologies available based on the use of chlorine, flocculation and sedimentation.
Palgey Maim proposed its innovative Nano-Bubble solution technology, which has a significant advantage in terms of efficiency in removing iron (Fe) and manganese (Mn), both in the context of non-formation of the negative by-products (in terms of health) obtained as a result of the use of chlorine and with regards to the testing process.
Moreover, the use of chlorination facilities in the wells located near populated centers was saved.
**The most common and cheapest chlorination method is based on gaseous chlorine
The engineering solution
The proposed solution is designed to treat well water with a flow rate of 144 m3 per hour – 40 liters/second
The proposed solution is built of two primary modules.
Module 1 – three Nano-Bubble reactors + ozone (obtained from an ozone generator).
Module 2 – sand filtration (12 pressure filter units).
Facility Description
- Facility for removing iron (Fe) and manganese (Mn) (flow of 40 liter/hour)
- Three reactors in which Nano-Bubble generators installed and fed with ozone
- A pressurized sand filtration system that includes 12 filters
- Control system
- Two units for exporting ozone 100 gr/hour
- Two pumps 160 m3/hour 35 meters (feed for filtration)
- Continuous monitoring system for turbidity and dissolved ozone.
