There are three basic components in the BacComber system.

An electromagnetic descaler - for scale control

An electromagnetic magnetite generator - for corrosion control

A copper-silver ionization unit- for bacteria, algae & slime control

Electromagnetic Descaler

Principle of operation

The BacComber electromagnetic generator produces a specially designed time varying electromagnetic wave through the inductor coil unit. When water passed through the inductor coil unit, water molecules and calcium ions are "excited". This resulting in three remarkable effects:

1) Excited water molecules will trap the calcium ions and prevent the formation of calcium carbonate. 2) Calcium ions which are not trapped can precipitate into calcium carbonates. The scale thus formed at this higher energy level is called aragonite. It is different from Calcite, its counterpart formed at lower energy. Calcite is hard and adheres strongly along the pipe walls. Aragonite, on the other hand is powdery and can be dislodged easily from surfaces. 3) Excited water can cause disintegration of the existing scale present in the system thereby improving the heat transfer efficiency.

BacComberBacComber Electromagnetic Descaler Effectiveness

a) Prevention of calcite scale formationDescaling effectiveness of the BacComber can be easily verified by a simple experiment.

Water with hardness of 300 - 400 ppm, PH=9, TDS=1500ppm approximately are placed in two bakers or containers. In each container, a small pump is used to circulate the water through a transparent hose. The water in both containers are then heated to 70 degree C to promote the growth of hard scale. In one of the containers, the transparent hose is passed through the BacComber electromagnetic coil unit for treatment. The other act as a control with no treatment. After 2-3 hours, it can be seen that the hose transporting water treated by the BacComber remains very clear without any scale deposit. The hose of the control has significant quantity of hard scale deposited along the hose wall. This provides unambiguous evidence of the descaling effect of the BacComber.

b) Descaling effectExisting hard scale in pipelines / equipment surfaces will disintegrate after weeks or months of treatment with the BacComber. Some examples are cooling towers, process equipments, boilers that have water treated by the BacComber. Following pictures show scales detached from the boiler drum and descaling in the cooling water pipe.

Benefits•Saving in energy consumption due to scale prevention and removal. $$$•Cleaner system resulting in lower bacteria level.

BacComber Electromagnetic Magnetite Generator

Basic PrincipleIron oxide, Fe2O3 commonly known as "red rust" is unstable and will detach itself from the steel surface. Hence, the steel willcontinue to corrode as the "red rust" do not act as a protectivelayer. Rust formed on steel surface is usually Fe2O3 as this compound requires the lowest energy of all types of iron oxides.When the steel surface and water are electromagnetically excited by the BacComber magnetite generator, they acquired a higher energy. This causes the formation of "black rust" called "magnetite". The magnetite is also a form of iron oxide but has the composition of Fe3O4. As the magnetite is magnetic, it adheres to steel surfaces in contact with water. Unlike the Fe2O3, the magnetite Fe3O4 layer is stable and will act as a protective layer preventing further corrosion. It also has "self-repair" property when damaged.

Corrosion Control EffectivenessThe overall corrosion control effectiveness in a cooling water system can be monitored by the free Fe ion present in the water.In the event of severe corrosion, the Fe ion increment in the water will be correspondingly high. When the corrosion is minimal, theFe ions increment will be low. For cooling water treated by the BacComber system, the Fe ions level will stabilize after descaling. Typical readings are below 0.08 ppm.

Benefits•Less corrosion related repair and maintenance expenses.•Saving in capital equipment replacement cost.•Better bacterial control due to less corrosion.

BacComberBacComber Copper-Silver Ionization Unit

Basic PrincipleThe fact that copper and silver ions can be used for disinfection and algae control has been widely recognized and proven.The AC power supply current, after passing through the BacComber ionization unit, is first converted into a low voltage DC current and discharged into the water through the electrodes. When the DC current passes through the copper and silver electrodes, copper and silver ions are produced and discharged into water. The copper ions in water will kill bacteria while the silver ions will alter the bacteria DNA and prevent the bacteria from multiplying. The copper and silver ions also have the effect of controlling algae and biofilm growth.

Copper - Silver Ionization EffectivenessCooling tower treated with BacComber system can achieve a low bacteria count. Legionella bacteria can also be controlled effectively. BacComber ionization is a continuous disinfection process and will maintain the bacteria count at low levels at all times. Cooling towers with preciously high bacteria count by chemical treatment can see significant improvement in the bacteria counts after the BacComber treatment. Typically, cooling towers with initial Total Bacteria Count (TBC) exceeding 100,000 cfu/ml, can improve to 3,000cfu/ml or less after BacComber treatment.

Benefits•Saving in energy due to the reduction of biofilm.•Ensuring the safety and health by reducing the risk.•Minimizing Legionellosis disease outbreak claims and possible loss of property income and value.

BacComber System Installation

The BacComber electromagnetic descaler & magnetite generator arehoused in one enclosure and mounted outside the cooling tower together with the copper-silver ionization unit and ELCB enclosures.

Submersible pump placed in the sump delivers water through the coil unit and discharges back to the sump through the holes drilled along the PVC pipe.

BacComber System Applications

The BacComber is a hybrid system consisting of an electromagnetic descaler-magnetite generator and a copper-silver ionization unit. The ionization unit or the electromagnetic generator may also be used independently as required .

For water systems requiring only scale and corrosion control, use only the electromagnetic descaler - magnetite generator.

•Boiler water•Process equipment water •Irrigation •Water Storage Tank

For water systems require only bacteria control, use only the copper-silver ionization unit.

•Fountain•Swimming pool•Aquarium

For water systems requiring all round control of bacteria, scale, corrosion, algae and slime, a complete BacComber system should be used. These applications include

•Cooling towers

•Hot spas and tubs

•Chilled water system•Potable water system•Agricultural / Hydroponics•Closed circuit cooling water system

•Drinking water•Spa

•Potable water storage and distribution system•Cooling system using recycled wastewater
