Drinking and Utility Water Chemicals

The biofilm layer formed due to the multiplication of microorganism in drinking and utility water may spread along these systems and may have pathogenic effect. The control of furring, corrosion, and the biofilm layer in the drinking and utility water and in the network through which this water is transferred is essential for the quality of drinking/utility water. The corrosion and furring formed in these systems lead to an increase in the concentration of heavy metals in the water and thus impair the quality of drinking water. Also, the furring, corrosion and other impurities that accumulate in drinking/utility water pipelines cause narrowing in the diameter and pitting on the pipe, thus it increases the energy costs of the company.

Our drinking/utility water chemicals are produced in accordance with the FDA norms.

The aim of heat transfer systems that benefits from the energy transfer characteristics of the water, is to transfer the heat, which is loaded to the water with very high costs in central stations, to another location with the highest possible efficiency. For this purpose, it is tried to minimize the effects of the factors that may block or slow down the heat transfer, or the failures which may occur in the heat transfer systems.

Designed for non-stop operation, the heat transfer systems are like the heart of the facility. For this reason, the heat transfer systems have no tolerance for an unexpected halt. In terms of electronics and mechanics, the operation should be planned and carried out without any fault.

The basis of the water treatment concept is to use the water that has the optimum conditions, in the system. Possible Ca and Mg salts contained in the water, cause furring in the form of crystals on the heat transfer surfaces. This furring hampers the heat transfer and causes energy loss. In addition, dissolved gases in the water, mostly the oxygen, cause corrosion by reacting with the metal components of the system. And the corrosion leads to deformation in the system equipment thus it causes failures and dangerous accidents.

Specialized in water management, Deren Kimya takes the responsibility of the operation of the system in terms of water, through the Water treatment Program implemented by the service engineers. At first, it ensures the use of optimum conditioned water in the facility with the optimum investment, then it ensures that the system operates with the most proper control parameters by using preservative chemicals to eliminate the risks of furring and corrosion that might be caused by the water in the system.

   The machines and equipment at various locations in the plant get heated due to their functions and therefore their efficiency decreases as they get warmer or even they cannot function because of thermal increase. And certain areas in the plant need to be cooled.

   The aim of the cooling systems that also benefit from the heat transfer characteristics of the water, is to cool the machines and equipment at various locations in the plant, and to ensure that the systems operate under the certain temperature through the continuous cycle of the water that is cooled in a central station.

   For this purpose, it is tried to minimize the effects of the factors that may block or slow down the heat transfer, or the failures which may occur in the heat transfer systems.

   The main purpose of cooling water treatment is to ensure the prevention of the lime salts in the water from causing furring layer at the heat exchangers of the system’s cooling process. Also, the biological formations, that can be widely seen in the water which is exposed to air and sunlight in open air environments, such as algae and fungus can cause deposits and blockage in the system. In addition to the corrosion caused by the reaction of oxygen in the water with the system metals, as the water allows electrons transfer, it causes cell corrosions between the system metals and therefore it causes failures in the system due to wearing away.

   Specialized in water management, Deren Kimya takes the responsibility of the operation of the system in terms of water, through the Water Treatment Program implemented by the service engineers. At first, it ensures the use of optimum conditioned water in the facility with the optimum investment, then it ensures that the system operates with the most proper control parameters by using preservative chemicals to eliminate the risks of furring, corrosion and biological contamination that might be caused in the system by the water.

Reverse Osmos Membran Kimyasalları

In theory, the nearly pure water is the best quality water for applications requiring industrial use of water. Dissolved solid matters and impurities in the water reduce the quality of the water. Therefore, reverse osmosis systems are the most common systems and the most efficient water treatment systems to produce high quality water for the industrial applications, in terms of operating cost.

The impurities in the water are expected to be resolved during the transfer of water through special filters, called membranes, under high pressure. In a general, 75% of the water transferred through the membranes is obtained as nearly pure water (below 50 ms) as a product, and 25% of it is obtained as concentrated waste.

Due to the filtration process performed by the membrane filters, contamination and blockage occur over the time. In order to ensure the membranes to operate with high efficiency and for long time, antiscalants applications are carried out as preservative chemicals.

Specialized in membrane preservation applications, Deren Kimya ensures the operation of Reverse Osmosis Systems with the highest efficiency through its own Membrane Master Program by antiscalants applications depending on the properties of the membrane and water. The unit cost of water obtained from reverse osmosis equipment can be kept low by using this membrane software.
