The allowed injection dose of membrane anti-fouling agent is influenced by important factors such as detailed analysis of incoming water, water flow rate, water pH level, system recovery, water tank, injection pump degree, solution concentration and type and arrangement of membrane filters. The dosage of antiscalant injection in the system is mainly around 1 to 6 ppm. However, it should be noted that the injection of antiscalant must be done accurately, because the inappropriate dose of this substance, even slightly above the permissible limit, can lead to fouling of the membrane.
In the industrial water treatment system, antiscalant is usually injected into the device after sodium meta bisulfite to remove the chlorine in the water before it enters the membrane filter. The proper injection dose of antiscalant in the reverse osmosis system is measured as follows: amount of antiscalant consumed in 24 hours (gr) = (1-6ppm) recommended dosage x volume of water entering the system in (m3) for 24 hours

Checking the condition of the installed equipment:
The installed equipment and systems are damaged and lose their efficiency under the influence of the expiration of their useful life as well as unfavorable environmental conditions. This issue is especially seen in instrumentation and control systems.
Examining the condition of the control system and instruments in order to create the necessary ground for renovation is of particular importance and requires appropriate experience. This company provides the required engineering services by relying on the experiences gained from similar projects. Inspections are based on the site visit, as well as the review of relevant technical documents and existing maintenance reports.
Examining the issues and problems in the above fields and providing solutions:
After carrying out the above studies according to the existing experiences of engineering standards and also taking into account the advances made in technology, the future solutions are determined and presented in reports explaining the limits of the advantages and disadvantages of each.
Feasibility of rebuilding systems in the industry:
Reconstruction or renovation of control systems and instruments needs to be investigated from two aspects. One is the cost that the supply of the replacement system or equipment imposes on the industry, and the other is the problems and finally the cost that arises in the replacement phase due to the interruption in production.
On the other hand, the significant benefits of the modernization of the control system can justify the above costs in certain circumstances, but the determination of this issue as well as the investigation of existing technical issues and obstacles requires specialized studies and requires sufficient experience in this field. .
Relying on the technical knowledge available to experienced experts, as well as the implementation of instrumentation and control design projects, this company is able to provide the necessary consulting services regarding the recognition of the process and the possibility of defining advanced control in the desired process, preparing the necessary documentation to define the issue. Provide design or cooperation in selecting the designer and finally create the necessary documentation for the realization of the completed design.
