Over the past few decades, waste water treatment has seen radical changes as world population continues to increase and concern over the environment grows. Waste water essentially means water affected by human activities such as domestic, agricultural, industrial and commercial activities.
Unlike many other manufacturers who view water and waste water as one and the same, SIGMAFLOW offers products specifically suitable for the particular use. Our commitment is to provide reliable, cost effective valves that offer the best possible solution for the particular application. The waste water process is generally segregated into three phases: Primary, Secondary and Tertiary.
- During the primary stage of waste water process, it is necessary to have valves that are able to handle slurries, as the wastewater at this point still has sediment, solids and sludge.
- During the secondary stage, actuated butterfly valves and check valves are used as the remaining organic matter is removed for which these types of valves are effective.
- During the tertiary stage, check valves, shut-off valves and butterfly valves may be used because, by this stage, there is no longer sediment in the waste water.
