1. A coarse suction filter located at the pump inlet;
2. A high-pressure oil filter situated in the oil circuit at the pump outlet;
3. A low-pressure oil filter located in the system's return oil circuit;
4. A bypass filtration system installed external to the main system.
5. Since the adsorption capacity of an activated carbon filter has a specific saturation limit, the filter's adsorption efficiency will diminish significantly once this saturation capacity is reached. Therefore, it is essential to monitor the activated carbon's adsorption performance and either replace the carbon promptly or regenerate it through high-pressure steam sterilization.
It is worth noting that during the initial stages of using activated carbon (or immediately following a carbon replacement), minute quantities of extremely fine activated carbon powder may be carried by the water flow into the reverse osmosis (RO) system. This can lead to fouling and blockage within the flow channels of the RO membranes, resulting in elevated operating pressures, reduced permeate production, and an increased pressure drop across the system. Furthermore, this type of damage is often difficult to remedy using conventional cleaning methods. Consequently, the activated carbon must be thoroughly rinsed to remove all fine powder particles before the filtered water is directed to the downstream RO system.
