Solutions for water treatment in small and medium-sized populations
We develop efficient solutions to meet the particular wastewater treatment needs of small towns, up to 2.000 population equivalent (PE), and medium-sized towns, up to 4.000 PE.
Domestic wastewater treatment plants.
Salher provides appropriate wastewater treatment solutions to small and medium populations, addressing the following challenges :
Economic:
Low or equal to zero energy consumption.
Technical:
Extremely simple installation, strong, durable and high performance equipment.
Management:
Immediate start-up, equipment able to operate right after the completion of connections, low maintenance.
Aesthetic:
Compliance with aesthetic and landscape impact criteria.
Other issues deserve special consideration such as isolated population and seasonality. Some towns multiply their population in summer, significantly increasing the volume of wastewater, with the added problem of summer water shortage.
Within its range of plants, Salher distributes wastewater treatment systems for small communities up to 50 PE for family homes, rural hotels and campsites, among others.
Reuse of treated wastewater.
Salher provides greywater and rainwater reuse systems. These systems, complementary or independent of urban wastewater treatment, are made of strong and unalterable materials, with designs to reach the highest efficiencies with the lowest operation and maintenance costs.
