By the following pre-treated raw water stream the filter material is precoated to the special Berkefeld filter candles located in the precoat filter, and there it forms the filtering layer. Flow direction in the precoat filter is upwards (see attachment 6).
  • Page 3 Standard dosing plan “Berkefeld EMERGENCY EXERCISE and ACTION (full) SDP“ 1. The Berkefeld SDP is used in case of disaster abroad with unknown waters and - in reduced extent - for exercises. 2. The EMERGENCY EXERCISE SDP is used with extremely strongly polluted, unknown waters or in case of chemical disasters.

    Install the raw water pump as close to the intake place as possible. Connect one or two raw water suction hoses with strainer, protective basket and plastic float with chain on suction side. Secure the suction valve and hoses with an arrester cable. Hang the raw water inflow pipe into the first raw water tank and connect it to the raw water pump with a corresponding number of raw water pressure hoses.

  • Page 8: 1.3 Precoat Filter

    IV 1.3 Precoat filter The precoat pump has to be connected with the four-way suction valve. A raw water suction hose has to be connected from the raw water collector to the four-way suction valve (C-Storz). The precoat hose which is 2 m long and which is equipped with one Storz coupling D only has to be connected to the four-way suction valve.

    supporting ring and the cover has to be laid on the bracing (see annex 1). Brace the cover with the cords at the supports of the supporting ring. Pay attention to utmost cleanliness at the pure water tank. Attention Then on suction side the pure water pump is coupled with a pure water suction hose and a gate valve to the pure water tank (Storz C).

    The deaerators have to be opened from time to time, so that entered air can escape. After approx. 5-7 min. circuit operation the 3-way tap is brought to position „filtration“ again. The first water (approx. 30 sec.) should be used for rinsing of the pure water pipes. Only hereafter the pure water inflow pipe is put in the pure water tank.
  • Page 11 valve and ball valve are closed, the pressure manometer on precoat filter side shows approx. 3 - 4 bar. The ball valve at the sludge outflow hose is opened suddenly and remains open for approx. 5 sec., then close slowly. This process must be repeated 6 times.

  • Page 13 The unit is used for dosing of water treatment chemicals in mobile drinking water purifiers. Installation can be carried out preceding or after a Berkefeld precoat filter plant by coupling the unit with the connections between 2 hoses. Dosing is carried out continuously into the treated pure water.
  • Page 14 IV 1.4.3. Chemical addition in proportion to the water supply The quantity of the chlorine added is determined by the corresponding responsible man in each single case. If no instruction has been given, we recommend to adjust chlorination of the water having a chlorine excess of 0.5 - 1 mg Cl The following mentioned common chlorinous chemicals are used: 1.

  • Page 16 8. Control function of the dosing unit at the control valve and overflow pipe If the outflow for filling of a tanker has been elevated, the dosing quantity has to be changed. Re-adjustment at control valve is absolutely necessary. If no pure water is given and the filter plant is switched to circuit, the control valve and gate valve have to be closed or the quick-coupling has to be separated respectively.

  • Page 18 The quantity flow rate meter has to be controlled continuously during operation of the precoat filter. Should - for any reason - the precoat filter suck air or should the precoat pump fail, one would recognize this at the float of the flow rate meter and one could switch the 3-way tap to „circuit“, so that the pure water cannot be polluted.
