If the distance is exceptionally long, or the amount of grease more than normal, a grease trap should be installed close to the house. For restaurants, etc. the installation of a grease trap is always recommended. In the first settling tank, the solid particles are stopped and gradually liquefied. Accidental dumping of small amounts of detrimental substances are partially taken care of in this tank. Liquid and suspended solids flow into the second tank. This tank is the aeration tank. Here, by means of one or more bubble aerators (see the table on page 3) oxygen is dissolved into the liquid obtaining optimal mixing and consumption of the biological waste. The pump of the Opur Supercompact works continuously, whereas it works intermittently in the WZ. The aerators can easily be removed and reinstalled (for inspection or cleaning) without having to empty the tank. The third tank is the second settling tank (secondary sedimentation). Here the sludge settles down and from this tank the purified water is discharged from the still water area. There is no need to add bacteries during the start-up of the system. OPTIONAL Alarm (standard with the WZ): functions by means of differential pressure, to be installed between the aerator and the aeration pump. Please contact our technical service to determine the correct number of inhabitants.

The installation requirements should be read FIRST BEFOR placement. In the event of loss by the customer of the installation requirements the customer must always ask for a new copy of the installation requirements at Boralit nv, or download them from the Boralit Web site. For CE-installations it is mandatory to choose a contractor who has been approved of by Boralit. If not, please inform your contractor to get in touch with us. This is in order to get your recognition. B.3.1 INSTALLATION PROCEDURES IN CONSOLIDATED SAND They apply to the articles under categories B 1.3, B 1.4 and B 2. WHERE TO INSTALL? Find a place were the facility can be easily installed and where the drain of the house can be led. Check for enough fall to the drain of the infiltration-facility. Make sure there is no possible flow-back from flooding, high water, heavy rainfall. The pump(s) should be in a dry and well-ventilated place. At preference in a cellar, garage, shelter or a separate room. The standard delivered aeration pump can be installed up to 15 m from the aeration tank. In case there is a greater distance between the pump and the system, please contact us as this will require a pump with more power. It is also possible to install a special stainless steel pump housing (see B.2.5 options) near the wastewater treatment system. This way, the pump can be installed near the aeration tank and it will be protected against bad weather. What’s more, the pump will be easy to reach during maintenance of the system. TABLE OF CONTENTS Boralit products category B – Water treatment Version 2013 v3 - English 11 Boralit N.V. - Nijverheidslaan 12 – 9880 AALTER – Belgium Tel.: +32 (0) 9 375 11 11 – Fax: +32 (0) 9 375 22 22 Site: www.boralit.com - E-mail: sales@boralit.com HOW TO INSTALL? ? Dig a square pit of adequate dimensions. See to it that all ground water present in the pit, is pumped out. Once the pit is dry, it must be covered by at least 10cm of consolidated sand (150 kg/m³). Make sure the sand is level so the tank is installed perfectly level to insure proper flow through the system. A concrete cap can be placed over the tanks to prevent tank floatation from groundwater pressure. ? Install the facility in correct order (tank 1: primary-sedimentation, tank 2: aeration tank, tank 3: secondary sedimentation). The arrows show the direction in which the water will flow. ? Connect the drain pipe of the house (if necessary, install a grease-trap between drain and wastewater treatment system) with the inlet of the facility (tank1: primary sedimentation). ? Connect the outlet of the wastewater treatment system with the drain pipe that goes to discharge or dispersal area, ... Make sure there is no flow-back possible. ? Connect the tanks (only for types WZ). ? Fill up the 2 (3) tanks with water through the first tank and let the water flow from the first tank through the other tanks until all tanks are filled with clear water. Attention: the secondary sedimentation tank (last tank) should be filled as follows: first fill the cone, then fill the outer part of the tank. At the same time backfill the pit round the tanks with consolidated sand (150 kg/m³) up to the level of the in-and outlet. ? Pull up the ballast-blocks from the aeration tank with the provided ropes. Screw the aeration discs on the provided screw thread and lower the blocks back into the tank. ? Saw the risers to the correct height to have them at ground level. ? Make sure there is adequate ventilation of the primary sedimentation tank and on the aeration tank. For this purpose the primary settling tank has been provided with a 50 mm pipe and a muff pipe DN100 (Ø110 mm) in the riser. Connect them to a T of 110 mm with reduction to 50 mm and lead the 110 mm to a well-ventilated place (For the Opur Supercompact the connection between tank 1 and 2 has already been made). Bring it to sufficient height above the ground and fix 2 curves 110 mm 90° to get a chimney-effect. ? Connect the aeration tube(s) and the aeration pump(s). For this, use a tube of 110 mm through which the aeration tube goes from the aeration pump to the manhole of tank 2. In case of several pumps, either pump can be put on either connection. ? Back-fill the pit with consolidated sand (150 kg/m³) to requested level. Remark: In case the facility gets embedded deeper in the ground than is permitted by the PE-riser, or in case one wants to make a manhole himself (e.g. brick-work) a support structure or concrete cap should be installed. This structure or cap should not rest on the tank nor on the brick-work and should divert the pressure to undisturbed ground. TABLE OF CONTENTS Boralit products category B – Water treatment Version 2013 v3 - English 12 Boralit N.V. - Nijverheidslaan 12 – 9880 AALTER – Belgium Tel.: +32 (0) 9 375 11 11 – Fax: +32 (0) 9 375 22 22 Site: www.boralit.com - E-mail: sales@boralit.com BE CAREFUL In case any vehicles might drive in the immediate surroundings of the facility: ? A strong cover should be used e.g. pedestrians’ 50kN, vehicles 125 kN, trucks 250 kN or heavy weight vehicles 400 kN. ? The cover should be cast in a sufficiently strong, reinforced concrete slab (=pressure plate) to avoid any immediate pressure on the tanks (ask for information at a recognized technician or desk). The slab should rest on the ground around the pit that has not been churned. ? The PE covers which come standard with the wastewater treatment system cannot carry the weight of persons/vehicles passing above the system and have no lock. That’s why you should always install Boralit PE covers that are adapted to the persons/traffic passing above them and which can be locked. ELECTRIC CONNECTION ? Connect (Branch) the aeration pumps to a grounded receptacle (230V) in a well-ventilated, dry place. Make sure correct fuses guard the electrical circuit. ? In case of installation of an alarm, it should be branched to a second socket or fixed connection. This alarm should be put in one of the aerial tubes from the pump to the aerator. ADJUSTMENTS All of the systems should be adjusted. Which means that the present flow-taps (possibly one or more) that are in the manhole of the aeration tank, should be adjusted correctly. This adjustment is not difficult but will take some of your time: ? Make sure the pump(s) are electrically connected and no possible waste water can enter the tank (the water should be at rest, wait until no more water enters the installation) ? The flow-taps should be closed. Accurately open the taps just a little bit. ? Let the facility work for some hours and check the level of the liquid in the middle-tank. ? On the PVC tube of the airlift you will find 2 marks. If the liquid is between the marks, the taps are correctly adjusted. ? If the liquid is beneath the lower mark, the taps should be closed some more. If the liquid is above the upper mark, the taps should be opened some more. ? Wait again for some hours and check again. Adjust more if necessary until the liquid is at the desired level. B.3.2 INSTALLATION PROCEDURES IN REGULAR SAND They apply to the articles under categories B 1.1 and B1.2 Follow above instructions and If there is no groundwater, the consolidated sand can be replaced by regular sand. Please contact us if the tank becomes more deeply embedded in the ground than is permitted by the PE-riser.
