SCR L 250-130 self-cleaning filter

Flow rate: 220 m³/h
By choosing a 25 micron filtration, the customer saved several hours of maintenance on the heat exchangers thanks to the filtration of the cooling tower water.
The washing discharge helps to maintain a stable level of saline concentration in the cooling tower water.

FILTER ELEMENT SECTION AND CLEANING SYSTEM

FILTRATION PHASE

During the filtration phase, the fluid (water) passes through the filter element from the inside to the outside, retaining all suspended solids larger than or equal to the installed filtration degree. The continuous deposition of suspended solids inside the filter cylinder creates an impediment to the passage of water, which translates into a pressure difference (∆P).

FILTER ELEMENT SECTION AND CLEANING SYSTEM

WASHING PHASE

At a set value of ∆P (adjustable 0.3 ÷ 1 Bar), the automatic cleaning cycle of the filter cylinder takes place. This operation starts with a signal that opens the drain valve, and connects the suction nozzles with the external environment. At the same time, the electric motor creates a rotational movement that allows the nozzles to inspect the entire filtering surface, washing a small portion at a time. This allows for very high washing efficiencies and limited portions of water in discharge. The dirt is evacuated through the drain valve. The cleaning cycle lasts approximately 15/20 seconds.

TECHNICAL SPECIFICATIONS OF THE PLANT

The plant filters canal water at a flow rate of 54 mc/h with self-cleaning filters having the following sequence:

• First filtration step 500 microns
• Second filtration step 80 microns
• Third filtration step 10 microns
• Fourth filtration step 1 micron

The plant will operate with a maximum SST concentration of 250 mg/l. The guaranteed filtration efficiency is 90% for particles ≥ 2 microns.
