Tips For Selecting The Valve For Medical Wastewater Treatment

Since the 20th century, the rapid development of pharmaceutical industry has brought a leap to human civilization and solved many plague problems. At the same time, the wastewater discharged from its production process has caused pollution to the environment, affecting human life as well as health.

What Is Medical Wastewater?

Hospital wastewater contains three major categories of pollutants, one of which is pathogenic microorganisms, the other is toxic and harmful physicochemical pollutants, and the third is radioactive pollutants. These medical wastewaters have complex composition, high concentration and salinity, high chromaticity and toxicity, and contain a wide variety of organic pollutants, many of which are difficult to biochemically degrade and can remain in the environment for a considerable period of time. Therefore, the treatment of medical wastewater is urgent and we must solve it in order to guarantee the safety and health of human living environment.

How To Treat Medical Wastewater?

For the treatment of medical wastewater, biological oxidation method and disinfection process are mainly used for treatment at present.

● The traditional biological oxidation method mainly includes biological contact oxidation method, biological carousel method, tower biofilter method, jet aeration method, oxidation ditch method and biofilm (MBR) bioreactor method.

● Disinfection process mainly includes chemical disinfection and physical disinfection process. The chemical disinfection process is specifically liquid chlorine, chlorine dioxide, sodium hypochlorite and ozone. The physical disinfection process is mainly UV disinfection.

Valves, pipes, pumps, flow meters, membranes, tanks and other industrial components can be assembled into an efficient medical wastewater treatment system. Valves play a role in transmitting and regulating the flow. Depending on the capacity or purification effect, a signal is input to the control system to adjust the opening and closing angle of the valve, thus achieving fluid automation. Thus, valves can help medical wastewater treatment systems to accomplish the purpose of water purification and complete the task efficiently.

Types Of Valves For Medical Wastewater Treatment

Considering that medical wastewater contains all kinds of corrosive or toxic substances, we suggest choosing the right valve material according to the process. Valves are available in stainless steel, biaxial steel, carbon steel, cast iron, UPVC, PTFE, PVDF and other materials to meet fluid control requirements.

Shut-off Valves

Shut-off valves are valves used for flow and cut-off. Their advantages are simple operation, easy installation and low leakage. Shut-off valves are generally available as ball, butterfly, gate and globe valves. Meanwhile, shut-off valves can work with electric actuators or pneumatic actuators to achieve remote control purposes.

Control Valves

A control valve is an industrial valve used to regulate the flow and pressure of a pipeline. It receives and feeds back signals through positioners or electric actuators to achieve precise flow regulation. According to the driving method, control valves are divided into pneumatic control valves and electric control valves.

Check Valves

Check valve is a valve that relies on the internal pressure of the pipeline to open or close automatically. Check valves can effectively prevent the backflow of media to protect the safety of pumps, flow meters and other electrical equipment, so that the whole pipeline operation is safe and smooth.


Y-Strainer contains a strainer, which can help filter solid impurities inside the pipeline as well as help extend the life of pumps, valves, flow meters and other industrial fittings, reducing maintenance costs.

These are the 4 types of valves that can be used in medical wastewater treatment systems. Choosing a suitable valve can make the system run more smoothly. We hope this article will help you in valve selection. Any demand for valve, feel free to consult us at

Tips For Selecting The Valve For Filter

Groundwater can be developed and utilized as a water source for domestic water, industrial water and farmland irrigation. Moreover, groundwater has the advantages of stable water supply and less pollution. It is an essential resource for human life and development. However, most groundwater contains excessive levels of iron and manganese, which can affect the color, taste and purity of the water source. If it is used directly, it will not only cause stains on utensils or washings but also affect other industrial production, such as paper making, textile industry, chemical industry, leather industry, etc. Therefore, when groundwater is required as a water source, iron and manganese removal must be carried out. We can choose to treat groundwater through iron and manganese removal filters to make groundwater a usable water source.

Benefits of Groundwater Treatment

1. Able to guarantee project quality
2. Able to ensure timely completion
3. Ability to reduce costs

Application of Valves In Iron & Manganese Removal Filters

Valves are widely used in various water treatment equipment, including iron and manganese removal filters. It is used to regulate the flow and delivery of water or other chemical agents. It is convenient to increase the productivity of the whole system.

Shut-off Valves

Ball valves, butterfly valves, gate valves and globe valves are widely used shut-off valve types. Their advantages are easy installation and easy operation. Only need to rotate the handle or turbine to open or close the valve, so as to achieve the purpose of transmitting or cutting off the flow.
Shut-off valves are available in stainless steel, carbon steel, duplex steel, cast iron or plastic. A variety of material options to match the needs of various types of pipes or water treatment systems.

At the same time, the use of electric actuators or pneumatic actuators can easily achieve the purpose of remotely controlling valves, reducing labor costs and effectively increasing production capacity.

Check Valves

The check valve is a valve used to prevent the medium from flowing backward. It uses the pressure of the pipeline to automatically open or close. It is generally used next to electrical equipment such as pumps to ensure the safe operation of electrical equipment.


Groundwater will contain solid impurities, in order to make the entire iron and manganese removal system run more smoothly and reduce maintenance costs. We recommend using a Y-type filter to filter solid impurities in the media.

The above is the introduction of valves that can be used for iron and manganese removal filters. Choosing the right valve can make your system run more smoothly and smoothly. Any demand, feel free to consult us at
