ETAR de Boelhe - Penafiel

The Package WWTP is dimensioned taking into account:

• Population to serve, as defined by applicable law
• Average flow rate, in L / day
• Affluence coefficient
• Receiving media

This type of equipment is especially suitable to:

• Small population agglomerates
• Urban lottings and housing and commercial areas, not served by a municipal draining system.
• Industries with biologically treatable wastewater such as wine processing, even when technological adaptations are necessary to bring the treatment to the characteristics of the effluent to be treated.

This technology has as main advantages the ease of installation and operation of the equipment and zero impact since the equipment is buried. The equipments are manufactured in GRP – Glass Reinforced Polyester or Carbon Steel with proper coating, and have a tertiary treatment if the receiving media so require.
