For water treatment plants to function optimally, it is best to automate the several different procedures used to treat water. This helps to achieve perfect delivery of results with minimum human intervention and thus reducing the possibility of human errors. NANDINI ENTERPRISES is a pioneer in the field, offering best-in-class design & engineering services to automation solution providers for water treatment plants. Our skills are augmented by inputs from our experts, who have deep knowledge of the processes at play in water treatment plants. Since we plan each project according to its merits, our services are tailor-made for the particular requirements of specific EPC / owner of water treatment plants.

Here are a few unit controls for water treatment plants where our engineering team has provided design engineering / implementation / FAT/ SAT support –

• Aeration control for easy control of aerator fountains which focuses on quality analysis and flow control of the water and adjusting the dosing of chemicals with respect to quality and rate of flow.
• Automated chemical dosing which allows you to control the amount of rate of dosing in proportion to the quality of the incoming water and its rate of flow.
• Clarifier automation which includes automated functioning of the flocculation and sedimentation processes. This makes the system more efficient by giving you complete control over the flocculation process and automating the opening and closing of valves for sludge removal.
• Automated water disinfection for worry-free results. This gives you the option to automatically adjust chlorination parameters and monitor the levels of residual chlorine in treated water for removal procedures.
• Water filtration automation for automatic monitoring and control of filter beds, monitoring and adjusting the rate of flow of water, and automatic periodical cleaning with back flush procedure which improves overall performance and productivity.

Water Treatment
We provide optimum solutions to improve the reliable operation of water treatment plants. These solutions include sophisticated technologies, unsurpassed product quality, and extensive application know-how throughout the lifecycle.

Desalination
The demand for seawater desalination as a stable water resource has been increasing. Yokogawa has a wealth of experience in controlling various types of desalination plant such as RO (Reverse osmosis), MSF (Multi-stage flash) and MED (Multi-effect distillation).

Water Pipeline
Water pipelines play an important role by transporting water from water sources, particularly in dry areas undergoing rapid industrialization and population growth. Yokogawa provides pipeline control solutions over distances as long as 600 km.

Water Distribution
One critical issue for a water distribution network is water leakage from the piping. Yokogawa provides water loss management solutions to minimize losses from the water distribution network, thus reducing non-revenue water.

Wastewater Treatment
Wastewater treatment plants use many motors, pumps, blowers, etc., and so it is important to reduce their electricity consumption in order to reduce running costs. Yokogawa provides optimum control solutions to improve energy efficiency.

Industrial Water
Industrial water is used in all industrial plants such as power generation stations, refineries and petrochemical plants. Yokogawa’s single control platform handles all water and wastewater control processing integrated with the main process.
