Page 3: Introduction
1 Introduction AQUALOOP direct (AL‐direct) is a direct filtration unit with an ultrafiltration membrane. The membrane technology retains even the smallest particles in the water, such as microorganisms, bacteria and viruses larger than 0.02 μm. AL‐direct can be operated either with geodetic pressure or with the aid of a pressure pump. The following waters, among others, can be filtered: Rainwater River water ... -
Page 4: Safety Instructions
(e.g. increase in turbidity), the system must be stopped, cleaned and checked immediately. The operator is responsible for compliance with the safety and installation regulations. The following points must be observed for installation and operation: Check the product for visible defects before installation. If there are any defects, the product must not be installed. All products must be checked regularly to ensure that they are in good condition. AQUALOOP-direct, manual version 1.0b_en... -

(or for ventilation during maintenance) so that the water can drain away. V1 V4 ‐ Outlet valve The clear water pressure pipe system to the consumers is connected to this connection. When commissioning the filtration unit for the first time, the filter unit must be flushed (see Commissioning) AQUALOOP-direct, manual version 1.0b_en... - Page 13 Commissioning 1. Close all valves except for inlet valve V1 and start the pressure pump 2. Carefully open vent valve V3 to allow the air to escape until water emerges. Then close vent valve V3 again. 3. Open the outlet valve V4 so that the filtered water can be pressed to the consumers. The AL‐direct ultrafiltration unit is now ready for filtering. Note: When using the ultrafiltration unit for the first time, discard the first approx. 30 litres of filtered water until clear water comes out of the system. In this case, connect a hose to the outlet and drain the water, otherwise skip this step. AQUALOOP-direct, manual version 1.0b_en...

Page 16: Dry Cleaning
All components must therefore be thoroughly rinsed with water after acid cleaning and before adding the chlorine solution! Observe and follow the warning and safety instructions for the chemicals used! Protective gloves, protective clothing and safety goggles must be worn during the cleaning process! We recommend mixing the cleaning solution with standard household cleaning agents as follows: 1) Acidic cleaning against precipitation, e.g. limescale with citric acid Concentration of the cleaning solution 1% citric acid a.) Citric acid in powder form Dissolve 100 g per 10 litres of warm, clean water (30°C) b.) Citric acid as a solution available in drugstores Add 200 ml per 10 litres of warm, clean water (30°C) 2) Alkaline cleaning against chlorine‐based biofouling NHCl Concentration of the cleaning solution 0.25% chlorine ‐ Observe the concentration and mix the cleaning fluid according to the mixing table below. AQUALOOP-direct, manual version 1.0b_en... - Page 17 If the desired filtration performance is not achieved after chem. If the desired filtration performance is not achieved after dry cleaning, the cleaning process can be repeated. Cleaning steps for cleaning with alcohol (only if oil and grease are suspected): 1. Fill the container with 10 litres of alcohol. 2. Immerse the membrane in the alcohol. 7. Leave the membranes in the cleaning solution for a minimum of 1 hour and a maximum of 24 hours. During this time, move the membrane up and down several times so that the cleaning fluid is exchanged in the membrane fibres. 3. After the cleaning time, drain the cleaning solution into a channel via valve V2. 4. Rinse the system clean at least twice with 20 litres of water (two buckets) each time. 5. As with the initial start‐up, the first 30 litres of the filtrate must also be discarded. AQUALOOP-direct, manual version 1.0b_en...
