Over the years, wastewater solutions around the world have become conscious about their uses. Water is the most crucial resource and companies are striving to limit the wastage of water. With that in mind, the demand for wastewater treatment has gone up as it helps in recycling and makes impure water resourceful once again.
There are many wastewater solutions available these days that come handy in setting up high-functioning wastewater or sewage treatment plants. From different valves such as swing type check valves to specialised system units like odour control units, many elements come into play.
In this post we have enumerated a few of the essential solutions/products that are used in wastewater treatment plants. Keep on reading till the end to find out more details about them.
Sewage/Wastewater Treatment System Valves
In any wastewater treatment system, there are different types of valves used for maintaining the flow of media. Whether it is to stop, open or regulate the flow, valves are used to perform the intended function.
Some of the commonly used valves that are found in such systems are sewage check valves, gate valves, sewage butterfly valves and more.
Butterfly Valves –
These are quarter-turn valves that are quite like a ball valve. This type of valve utilises a series of centre-mounted circular-shaped flaps that allows opening or closing of the pipe.
A butterfly valve’s handle is connected to the stem and the stem is connected to a disc found inside the valve. Butterfly valves are an excellent choice when it comes to regulating and shutting off fluids. These valves are also a great solution for pipes having a larger diameter.
Gate Valves –
Other than water supply and process plants, gate valves are also used in wastewater plants. The primary function of gate valves is to deliver the function of a shut-off valve, however, they are also great for regulating fluid flow.
There are many varieties available for gate valves as they come in different designs and seat features such as a metal seated gate valve. Gate valves come in really handy when isolation services are needed for a system for repair, maintenance or any section of the pipeline system does not need fluid flow.
Ball Valves –
Another valve that is found in many wastewater treatment plants are ball valves. Just like butterfly valves, these are quarter-turn motion operating valves that utilise rotating ported spheres inside the pipe to prevent or allow flow of fluid.
A ball valve not just helps in regulating flow of the fluid but also controls pressure within the system. They shut the flow of fluid from a compressed air line to a high-pressure hydraulic system. These valves are designed to be easy-to-operate and leak-proof.
Ball valves need only a 90-degree turn to close or open the valve.
While there are many other standard type valves used in wastewater treatment plants, there are also a set of specialised valves fitted to carry out certain specific operations. For example, duckbill check valves are specialised valve types that are mainly used for controlling the backpressure of sewage treatment plants in a cost-effective way.
Sludge Treatment Solutions
Sludge is a byproduct that is found in wastewater treatment plants. After the treatment of wastewater, the residue that remains is referred to as sludge. Sludge is either in solid, semi-solid or slurry form.
Sludge is generally classified as primary and secondary sludge. The disposal of sludge cannot be done just like that as it can be toxic for the environment and human life. This is why sludge needs to be treated appropriately before being disposed of or recovered.
Now there are a series of steps involved when it comes to treating the sludge. This means there are different types of solutions available in order to carry out the sludge treatment. Some of these solutions are –
Scrapers –
Scrapers are basically mechanically operated elements that are used in sedimentation tanks with a large diameter. They help in removing the sludge accumulated at the bottom of the tank. Scrapers for sludge treatment systems are an important element.
There are different types of scrapers available, each one of them serving the demands of distinct system application. For example, circular scrapers and more.
In recent times, there are scrapers for different sedimentation tank orientations as well. The longitudinal scrapers are one of the many types that are mainly used for rectangular-shaped sedimentation tank design. This scraper is designed to scrape out the sludge along with the sand residue longitudinally and subsequently transfer it into the collection hopper.
There are tons of other wastewater solutions other than these –
swing type check valves, scrapers, etc. that are in demand to establish the treatment plants.
