What is Commissioning?
Commissioning is a set of activities used to establish the integrity of the system's components and verification of its equipment’s, including all mechanical, electrical, and instrumentation devices, and to ensure the process's sustainability for satisfactory operation of the entire system. It is usually the last phase of any project before the handover to the owner and occurs immediately after the completion of all civil and mechanical construction.
Basic functions of commissioning
(a) Owners' Point of View- Did we get what we paid for in terms of an improvement once the project was completed?
(b) Engineers' Point of View- Can we demonstrate that we kept our promises made during design?
(c) Contractor's Point of View- Did we complete the project according to the plans and specifications?
(d) Viewpoint of a Regulator - Has a regulatory concern been addressed?
To commission equipment’s, we need a well-defined plan that includes-
(b) Methods for determining the effectiveness of the system. (For example, a chlorine feed system must be capable of releasing a specific chlorine residual, as well as a method for measuring the output of our metering pumps using an analyser);
(c) Methods for examining all kinds of monitoring and control, for example, pump control in "local mode" or via a process control network;
(d) The ability to simulate anomalous operating modes.
How to RO Plant Commissioning in India?
Netsol Water is a pioneer water treatment plant manufacturer offering best water management solutions using state-of-the-art technology.
Industrial and Commercial RO Plants offered by us are quite effective in removing all kinds of chemical, physical, and biological impurities from the water, and hence are extensively demanded across various industries. Our RO plants are known for long service use and are economically viable to operate and have maximum compliance with the regulatory authorities’ norms. Our service team stands right beside the clients while the entire commissioning of RO plants anywhere in India to train the on-site employees of the clients and to impart post-commissioning technical assistance, if required.
There are nine key elements for commissioning systems, which are usually carried out in three phases: pre-commissioning, commissioning, and trail operation.
All of these key elements are the same and applicable in a wide range of industries, including petrochemical plants, refineries, power plants, gas, most of thewater and wastewater treatment plants, with some limitations and adaptations, to fit each one.
Reverse Osmosis Plant Commissioning Elements
1: Planning, as we will not be able to commission a plant safely and on time if we do not plan properly.
2: Mechanical completion (MC) is the point at which the commissioning team takes over the system from the construction team's quality control.
3: Piping and instrumentation checking (PID checking) entails commissioning engineers ensuring that every pipe, device, and instrument in the field is in accordance with the approved PID.
4: Pre-commissioning, which entails cleaning of all pipes using various methods such as air ploughing and flushing before entering the commissioning step. Mechanical cleaning of vessels and tanks, as well as ensuring that motors and other equipment’s are not overloaded.
5: Commissioning, which includes things like introducing utilities, dry tests, wet runs, and hot runs depending on the industry, as well as safe flow dynamic testing, solving dynamic testing, and process flow testing. It is expected that many problems will arise during this stage, and they must be resolved before moving on to the next stage.
6: Start-up, which entails bringing the entire plant online, including all water supply connectors, pressure regulators, sedimentation, pre-filtration membranes, auto shut-off valves, reverse osmosis valves, and check valves in reverse osmosis plants.
7: The initial operation, which includes the preparation of performance tests for the entire reverse osmosis plant, takes place at which time the processes will be optimised and pump & other equipment’s adjustments will be made.
8: Performance testing, which includes ensuring that the water treatment plants meet regulatory requirements under normal operating conditions.
9: Following commissioning, the Engineers will address any grade C elements of the punch list, which are issues that do not immediately impair the operation or process. This may take a long time due to a shortage of funds, which is common at the end of many projects.
