Perfector-E
Contents
Technical specification
Operation
System operation is based on plug and play, making it easy for users to operate.
Treatment Efficiency
Maintenance
The system is very robust and almost no maintenance is required even under harsh circumstances. For example, in many places in the tsunami affected area and also in Haiti 2010 the perfector-E was successfully used as a purification system.
The machine does need to be cleaned, without moving it, every 3 months. This usually takes about 2 hours.
Manufacturing
It comes complete with power generator or solar panels/wind mill to produce the required electricity and a pump with a floating hose to feed the unit with the polluted water. The system can be bought from the manufacturer or an option to rent the unit is available.
Estimated Lifespan
The membrane lifetime is 3-5 years depending on water source quality.
Cost
| Capital cost | Operating cost | Replacement cost | Estimated 5 year cost | Cost / metre cubed treated |
|---|---|---|---|---|
| ~US$ 42.000 = €30.000 | € 1450/year (electricity) + € 500/year (salary) * | 2,5 * € 300 | US$ 30 (estimated cost over 1 year) | € 0,69 |
- Note: Assuming a lifetime of 5 years, 16 hours daily operation, meaning approximately 2.000 litres/day is processed, no membrane replacement is required. The UV lamp should be replaced every 2 years. The cost of one UV lamp is €300 (medium pressure; 9.000 hours). Operation cost is based on 16 hours per day * 3,1 kWh; electricity price in the Netherlands per kWh is €0,08. Hence, estimated annual electricity cost is €1450. Salary is assumed €500/year (fulltime); based on GNI per capita of least developed countries (World Bank).
Country experiences
The Perfector-E has been successfully applied and still in full operation in Indonesia, India, Pakistan, Peru, Soudan, Rwanda, Angola, Romania, Benin, south Africa, Egypt, Sudan, Kenya, Nepal, Philippines, Congo and China
