Waste Water Valve

Water is among the world’s most essential natural resources. Just as it aids in the development of human life and agricultural products, water is utilized to support various industrial processes such as heating, cooling, and sterilization. Transportation, management and treatment of the great quantities of water needed to supply growing global populations and industries requires large piping systems and treatment facilities.

The water treatment industry consists of three main segments: wastewater treatment, which removes impurities caused by any industrial process from nearby water supplies; boiler water treatment, which safeguards boiler systems against potentially hazardous chemical substances; and cooling water treatment, which maintains the integrity of recirculating water systems in industrial facilities.

Special materials are available to suit your needs. We can also work with you to ensure that our valves meet specific impact and specification requirements.

How to Select Waste Water Valve

To begin understanding how the waste water treatment valves process let us take a look in to these water treatment stations structures. The waste water treatment stations are designed in to a wet well or a wet and dry well design here the dry well usually contains the pumps and its related equipment. The valves that are deployed in a lift station are located in the basin of the wastewater, in a separate valve vault or in a dry well. The four main types of valves typically found in the lift stations include shutoff valves, check valves, air valves and knife gate valves.

The function of shutoff valves is the isolation when repair or maintenance is needed. The work of the check valve is preventing the reverse flow when the pump is turned off. Air valves are used to expel the air present in the pump column and the forces main to provide efficient flow to minimize the surges. Knife gate valves are used for their ability to cut through the sludge’s since they have flow resistance whereas in other valves are having blunt seating which will not cut the media and leads to operation failure.

Selecting valves for a wastewater plant is similar to that of selection of the pumps where the consideration must be given to the contents of solid medium of the flow media. The water treatment valves of these wastewater treatment plants must be selected to operate safely and consistently with higher efficiency so as to avoid unwanted maintenance situations that are costlier.

The main criteria that should always be considered while selecting valves are:

Purpose: Isolation

Parameters: Essential Flow, pressure and temperature.

Requirements: Frequency of operation, admissible rate of leakage, space available, level of cleanliness

Compatibility: Percentage of concentration, percentage of solids, media, and their density.
