Solve cooling tower troubles (adhesion of unwanted substances and reduced heat exchange)! Achieve significant savings in water and energy! [Patent obtained]
The CALFA SEP "Water Separator" gradually concentrates impurities into the lower layer by continuously and forcibly generating unique fluid cavitation with a special ring contained within the cooling water. For the total circulation volume of the cooling tower, continuous circulation is performed with CALFA SEP compatible models (one or multiple units) to separate and concentrate impurities (SS) in the cooling water that are "specific gravity 1.0 or higher" and "up to 7 microns." By regularly draining this concentrated material, it serves as a separation-type side filter that continuously purifies the cooling water.

basic information
By using our "environmentally friendly water treatment agent CALFA BAS," impurities in the water can be efficiently coagulated and concentrated, allowing us to extract only the "dirty water" with high hardness and turbidity that negatively affects the equipment. Additionally, there is no need for frequent "backwashing" like with sand filters, resulting in significant "water-saving effects." Furthermore, we use only the minimum amount of make-up water for the equipment, ensuring that only clean water is used for "circulation and heat exchange." With the cleaning action, scale prevention, and rust prevention effects of CALFA BAS within the equipment and piping, we can maintain healthy equipment at all times and achieve optimal heat exchange rates. As a result, substantial "energy-saving effects" are realized.

Applications/Examples of results
Comparison of sand filtration: Five "no" advantages 1. Frequent "backwashing" is required --> Significantly increases water costs --> S.E.P. does not require "backwashing" 2. Filter media must be replaced regularly --> Increases running costs --> S.E.P. does not require "media replacement" 3. Neglecting media replacement leads to --> Decreased "filtration capacity" --> Sand turns to stone and backwashing becomes impossible --> S.E.P. has no "decrease in filtration capacity" 4. Trying to increase filtration capacity requires --> Large space --> S.E.P. does not require large space for installation 5. Sand filters experience pressure loss, making them unsuitable for full stream use --> S.E.P. is not limited by "full side" usage

Company information
Calfa Chemical Co., Ltd. has developed the environmentally friendly cooling tower water treatment agent "CALFA BAS" (Calfa Bas) that is "phosphorus-free" and "nitrogen-free"! Using amorphous solid water treatment technology recognized in the environmentally advanced EU, it solves cooling tower problems (such as silica and calcium scale buildup, slime attachment, and reduced heat exchange) without the need for equipment or machinery! CALFA BAS (Calfa Bas) contains no "phosphorus" or "nitrogen" at all. Therefore, there is no need for "concentration measurement devices or systems" to measure residual amounts of "phosphorus" or "nitrogen." Additionally, actions such as diluting with water to meet "total water quality regulations" are unnecessary in themselves. [ISO 14001 compliant] Installation is simply placing it at the bottom of the cooling tower. That's all. It significantly achieves savings in water and energy! Some users in factories and large hotels have realized savings of several million yen in electricity costs over six months. By simply reducing power consumption (kWh) by 30%, the carbon dioxide emissions from power suppliers are also reduced by 30%, contributing to the mitigation of global warming, making the optimization of thermal efficiency essential.
