4. EQUIPMENTS

1. DESCRPTIVE MEMORY: At the present time, there are two filter systems in the channel, one after the other:

The first sieve, coarse roughing, works correctly and no action is required, the second sieve does not work properly, in addition the solid compaction and transport system is inefficient and does not transport the solids removed to the desired location, which would be in the outer road close to the existing curb:

2. DESIGN DATA: The channel width is 680 mm and the depth is 1,000 mm. The passing light of the new equipment must be 3 mm. The design flow used, according to the data provided by the treatment plant, is 134 m³/h.
