Remove more screening solids and reduce TOTEX and OPEX with small, packaged inlet works and larger escalator inlet screens.

Upgrading small WwTWs can be made easier for engineers using Hydro International’s M&N inlet works packages. They deliver screening, washing, transport, compaction and de-watering in a single ‘stand-alone’ package.

Engineers and operators can benefit from the many key operational features that provide both OPEX and TOTEX savings; including low power consumption, hard wearing components and easy access for routine maintenance as screens are fitted on pivotal frames.

For larger WwTWs with flows over 150 l/s an escalator or centre flow band screen will provide operators with an average capture ratio of over 85%.

Engineers can also increase flow throughput by up to 30% in the same footprint by switching to a specialised Frankenberger screen.

Due to reduced solids load ferric dosing plants and downstream processes will be more efficient. Removal of more solids than conventional screens at the inlet works can lead to a reduction in the amount of phosphorus that needs to be removed at the end of the process before discharge.

Prevent abrasion and clogging of plant equipment, and protect capacity and efficiency, by removing more and finer grit at the inlet works.

When upgrading WwTWs, adding or improving grit removal systems at the inlet works can help to prevent downstream processes from clogging with grit and reduce wear on conveyor systems including pumps.

Our range of grit management systems include grit removal, grit washing and grit classifying technologies that enable WwTW operators to remove more and finer grit more efficiently. This helps to reduce Totex costs by reducing wear on pumps and removal of grit from primary settlement tanks and improving efficiency of aeration and digesters.
